Black Arrow Cyber Advisory 26/04/2022 – Actively exploited vulnerability affecting Microsoft Exchange Server (on-premise)

Executive Summary

A vulnerability which was previously disclosed in May 2021 and confirmed to be actively exploited in August 2021 is still being actively exploited by malicious actors on Microsoft Exchange systems that have not been patched. This vulnerability can be exploited by any compromised user account that can access an unpatched exchange server using PowerShell, and is a potential ingress point for further attacks including ransomware. This vulnerability relates to Microsoft Exchange instances that are either ‘on premises’, importantly this includes any IT provider hosted private cloud instances.

What’s the risk to my business?

The initial exploit required related CVE notices for the three vulnerabilities known as ‘ProxyShell’ were classified as two critical and one medium. However, it is now being actively exploited with only the medium vulnerability used to deliver ransomware attacks to unpatched systems. The compromised account does not need administrative access and could be any account which makes phishing a very likely vector for initial compromise.

What can I do?

If your business is using Microsoft Exchange on-premise, ensure that the appropriate security updates have been applied. If Microsoft Exchange is being hosted by an MSP, then ensure that the MSP confirms the vulnerabilities have been patched. As these security updates are for Exchange which facilitates business email, the application of these patches can involve system downtime. Since these vulnerabilities are being actively exploited it is now recommended that the patches are applied as soon as possible.

Technical Summary

The following Microsoft Exchange products are affected by this vulnerability: Microsoft Exchange Server 2019, 2016 and 2013. To address this, KB5003435 was issued which targets four CVE vulnerabilities: CVE-2021-31195, CVE-2021-31198, CVE-2021-31207 and CVE-2021-31209.

Further information on the security update can be found here, including the specific updates for different systems, and troubleshooting steps if the update is not applying correctly. Details on each individual CVE can also be found through this link: Description of the security update for Microsoft Exchange Server 2019, 2016, and 2013: May 11, 2021 (KB5003435)

Black Arrow Cyber Threat Briefing 22 April 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

• Why Ransomware Attacks Prefer Small Business Targets Rather Than Rich Enterprises

Enterprise businesses with 25,000 employees+ are less likely to get hit by a ransomware attack than smaller businesses — even though big companies typically can afford to pay higher ransoms, the 2022 CyberEdge Cyberthreat Defense Report concluded.

What explains hackers taking aim at small businesses more frequently than enterprise giants?  The answer: Damaging a critical infrastructure facility or similar disruptions are certain to catch the eye of federal law enforcement, or national governments — something that no hacker wants, CyberEdge said. Smaller to medium-sized firms, as it turns out, get hit more frequently by ransomware attacks, on average at roughly 70 percent, the report said.

Overall, some 71 percent of organisations have been bitten by ransomware in 2022, up a point and a half from last year and by 8.5 points in 2020. It’s companies of 10,000 to 24,999 employees that are the sweet spot for ransomware hackers, nearly 75 percent of which are victimised by cyber extortionists.

The extensive study, which surveyed 1,200 security decision makers and practitioners employed by companies of greater than 500 people in 17 countries across 19 industries, is geared to helping gauge their internal practices and investments against those of their counterparts in other parts of the world.

• Ransomware Plagues Finance Sector as Cyber Attacks Get More Complex

Cyber criminals have evolved from hacking wire transfers to targeting market data, as ransomware continues to hit financial firms, says a new VMware report. Here's what to do about it.

Ransomware plagues financial institutions as they face increasingly complex threats over previous years owing to the changing behaviour of cyber criminal cartels, according to VMware's latest Modern Bank Heists report.

This has happened as the cyber crime cartels have evolved beyond wire transfer frauds to target market strategies, take over brokerage accounts, and island-hop into banks, according to the report.

For the report, VMware surveyed 130 financial sector CISOs and security leaders from across different regions including North America, Europe, Asia Pacific, Central and South America, and Africa.

Report findings were consistent with observations by other security experts. "The Secret Service, in its investigative capacity to protect the nation's financial payment systems and financial infrastructure, has seen an evolution and increase in complex cyber-enabled fraud," says Jeremy Sheridan, former assistant director at the US Secret Service. "The persistent, inadequate security of systems connected to the internet provides opportunity and methodology."

• 76% of Organisations Worldwide Expect to Suffer a Cyber Attack This Year

Ransomware, phishing/social engineering, denial of service (DoS) attacks, and the business fallout of a data breach rank as the top concerns of global organisations, a new study shows.

The newly published Cyber Risk Index, a study by Trend Micro and the Ponemon Institute, shows that more than three-quarters of global organisations expect to suffer a cyber attack in the next 12 months — 25% of which say an attack is "very likely."

More than 80% of the 3,400 CISO and IT professionals and managers surveyed say their organisations were hit with one or more successful cyber attacks in the past 12 months, and 35% suffered seven or more attacks, according to the report, which covers the second half of 2021.

• Most Email Security Approaches Fail to Block Common Threats

A full 89 percent of organisations experienced one or more successful email breaches during the previous 12 months, translating into big-time costs.

On overwhelming number of security teams believe their email security systems to be ineffective against the most serious inbound threats, including ransomware.

That’s according to a survey of business customers using Microsoft 365 for email commissioned by Cyren and conducted by Osterman Research, which examined concerns with phishing, business email compromise (BEC), and ransomware threats, attacks that became costly incidents, and preparedness to deal with attacks and incidents.

“Security team managers are most concerned that current email security solutions do not block serious inbound threats (particularly ransomware), which requires time for response and remediation by the security team before dangerous threats are triggered by users,” according to the report, released Wednesday.

Less than half of those surveyed said that their organisations can block delivery of email threats. And, correspondingly, less than half of organisations rank their currently deployed email security solutions as effective.

https://threatpost.com/email-security-fail-block-threats/179370/

• Financial Leaders Grappling with More Aggressive and Sophisticated Attack Methods

VMware released a report which takes the pulse of the financial industry’s top CISOs and security leaders on the changing behaviour of cyber criminal cartels and the defensive shift of the financial sector.

The report found that financial institutions are facing increased destructive attacks and falling victim to ransomware more than in years past, as sophisticated cyber crime cartels evolve beyond wire transfer fraud to now target market strategies, take over brokerage accounts and island hop into banks.

In the Modern Bank Heists report, 63% of financial institutions admitted experiencing an increase in destructive attacks, with cyber criminals leveraging this method as a means to burn evidence as part of a counter incident response.

Additionally, 74% experienced at least one ransomware attack over the past year, with 63% paying the ransom. When asked about the nation-state actors behind these attacks, the majority of financial instructions stated that Russia posed the greatest concern, as geopolitical tension continues to escalate in cyberspace.

• Hackers Sneak Malware into Resumes Sent to Corporate Hiring Managers

A new set of phishing attacks delivering the ‘more_eggs’ malware has been observed striking corporate hiring managers with bogus resumes as an infection vector, a year after potential candidates looking for work on LinkedIn were lured with weaponised job offers.

"This year the more_eggs operation has flipped the social engineering script, targeting hiring managers with fake resumes instead of targeting jobseekers with fake job offers," eSentire's research and reporting lead, Keegan Keplinger, said in a statement.

The Canadian cyber security company said it identified and disrupted four separate security incidents, three of which occurred at the end of March. Targeted entities include a US-based aerospace company, an accounting business located in the UK, a law firm, and a staffing agency, both based out of Canada.

The malware, suspected to be the handiwork of a threat actor called Golden Chickens (aka Venom Spider), is a stealthy, modular backdoor suite capable of stealing valuable information and conducting lateral movement across the compromised network.

"More_eggs achieves execution by passing malicious code to legitimate windows processes and letting those windows processes do the work for them," Keplinger said. The goal is to leverage the resumes as a decoy to launch the malware and sidestep detection.

• West Warns of Russian Cyber Attacks as Concerns Rise Over Putin’s Nuclear Rhetoric

Cyber crime groups have publicly pledged support for Russia, western officials worry about Putin’s reliance on nuclear threats and the battle for Mariupol in Ukraine grinds on.

The US and four of its closest allies have warned that “evolving intelligence” shows that Russia is contemplating cyber attacks on countries backing Ukraine, as the Kremlin’s frustration grows at its failure to make military gains.

Vladimir Putin used the launch on Wednesday of a powerful new Sarmat intercontinental ballistic missile (ICBM), capable of carrying ten or more warheads, to make nuclear threats against western countries.

The Sarmat has long been in development and test flights were initially due to start in 2017. The Pentagon confirmed that the US had been given notice of the test and was not alarmed. Western officials are more concerned by the increasing emphasis Moscow puts on its nuclear arsenal as its conventional forces have faltered in Ukraine.

The Ukrainian army continued to put up resistance in the besieged and devastated city of Mariupol, but Putin’s Chechen ally, Ramzan Kadyrov, predicted that the last stand of the port’s defenders at the Azovstal steel works would fall on Thursday.

The Kremlin has made repeated threats against the many countries that have been supplying Ukraine’s army with modern weapons, and members of the “Five Eyes” intelligence sharing network – the US, Britain, Canada, Australia and New Zealand – predicted Moscow could also work with cyber crime groups to launch attacks on governments, institutions and businesses.

• Criminals Adopting New Methods To Bypass Improved Defences, Says Zscaler

The number of phishing attacks worldwide jumped 29 percent last year as threat actors countered stronger enterprise defences with newer methods, according to researchers with Zscaler's ThreatLabz research team.

Cyber criminals have adapted to multi-factor authentication (MFA), employee security awareness training, and security controls by broadening who and where they will attack.

While the United States remained the country with the most phishing attempts, others are seeing faster growth in the number of incidents – exploiting new vectors like SMS and lowering the barrier of entry for launching attacks through pre-built tools made available on the market.

"Phishing attacks continue to remain one of the most prevalent attack vectors, often serving as a starting point for more advanced next stage attacks that may result in a large-scale breach," Deepen Desai, CISO and vice president of security research and operations at Zscaler, told The Register.

• Cyber Criminals Are ‘Drinking the Tears’ of Ukrainians

In biology, when an insect drinks the tears of a large creature, it is called lachryphagy. And in cyberspace, malicious actors are likewise “drinking tears” by exploiting humanitarian concerns about the war in Ukraine for profit. Different forms of deception include tricking people into donating to bogus charities, clicking on Ukraine-themed malicious links and attachments, and even impersonating officials to extort payment for rescuing loved ones.

It is an unfortunate reality that cyber opportunists are engaging in lachryphagy to exploit humanitarian concerns about the war for profit or data collection. To date, one of the largest cryptocurrency scams involving fraudulent Ukrainian relief payments totalled $50 million in March, the Wall Street Journal reports.

Immediately following Russia’s invasion of Ukraine, cybersecurity companies warned the public that criminals were preying on Ukrainian relief fundraising efforts with cryptocurrency scams. Bitdefender Labs reports that cyber criminals have impersonated Ukrainian government entities and charitable organisations such as UNICEF, and the Australian humanitarian agency, Act for Peace. “Some [scammers] are even pretending to be Wladimir Klitschko, whose brother Vitali is mayor of Ukraine’s capital, Kyiv,” according to the BBC.

• Hackers For Hire Attempt to Destroy Hedge Fund Manager's Reputation

Hackers bombarded a British hedge fund manager with 3,000 emails and fake news stories about his mortgage in an effort to destroy his reputation after being hired by a corporate rival.

Criminals even sought to gain personal information about Matthew Earl by pretending to be his sister in a three-year campaign when he raised concerns over the controversial German payments company Wirecard.

Mr Earl, a former City analyst who runs the hedge fund ShadowFall, said he was targeted by a group called Dark Basin.

This group has been linked to Aviram Azari, who this week pleaded guilty in New York to a conspiracy to target journalists and critics of Wirecard using phishing emails.

Mr Earl said the hacking attempts started in 2016 after ShadowFall, nicknamed the “dark destroyer” in the City, criticised the financial performance of Wirecard. The German company was later mired in a series of accounting scandals and went bust.

He said: “I was being sent very targeted emails, which were crafted with personal information about my interests, friends and family’s details. They were very specific.”

Mr Earl received news stories that appeared to be from media outlets such as Reuters and Bloomberg. Another email appeared to be sent by his sister, sharing family photographs, he added.

• New Threat Groups and Malware Families Emerging

Mandiant announced the findings of an annual report that provides timely data and insights based on frontline investigations and remediations of high-impact cyber attacks worldwide. The 2022 report––which tracks investigation metrics between October 1, 2020 and December 31, 2021—reveals over 1,100 new threat groups and 733 new malware families.

The report also notes a realignment and retooling of China cyber espionage operations to align with the implementation of China’s 14th Five-Year Plan in 2021. The report warns that the national-level priorities included in the plan “signal an upcoming increase in China-nexus actors conducting intrusion attempts against intellectual property or other strategically important economic concerns, as well as defence industry products and other dual-use technologies over the next few years.”

Economic Warfare: Attacks on Critical Infrastructure Part of Geopolitical Conflict

We’ve known for years that since at least March of 2016, Russian government threat actors have been targeting multiple U.S. critical infrastructure sectors including the energy, nuclear, commercial facilities, water, aviation, and critical manufacturing sectors. The Department of Homeland Security (DHS), the Federal Bureau of Investigations (FBI), and other agencies have acknowledged this for quite some time in many of their technical alerts and statements.

In the intervening years, with the acceleration of digital transformation, cyber criminals and nation-state actors have increasingly set their sights on these sectors. The convergence of physical and digital assets brings competitive advantage but also inevitable risks. Attacks against hospitals, oil pipelines, food supply chains, and other critical infrastructure, have brought into sharp focus the vulnerability of cyber-physical systems (CPS) and the impact on lives and livelihoods when they are disrupted. Now, overwhelming signs indicate critical infrastructure companies are in the bullseye of geopolitical conflict.

Black Arrow Cyber Advisory 20/04/2022 – Vulnerabilities identified within Lenovo Laptop UEFI BIOS

Executive Summary

UEFI Firmware provides an interface allowing for configuration of a computer at the beginning of the boot sequence, prior to the operating system loading. This firmware is supplied with every modern computer and allows an administrator to make hardware and security configuration changes to the system, while allowing the computer to boot successfully into the operating system. Lenovo has disclosed three vulnerabilities within this UEFI Firmware, affecting its consumer laptop range. These vulnerabilities could allow an attacker with local access to the machine to execute arbitrary code on the laptop.

What’s the risk to my business?

A malicious actor with local access to an affected laptop may be able to compromise the security and data stored on the laptop.

What can I do?

Updates to the UEFI Firmware on affected laptops are available and should be installed onto affected laptops. It’s noted that this firmware will need to be downloaded and installed from the Lenovo website, and these updates will not be supplied through Windows Update. As these firmware updates apply to low-level software that effectively makes the computer work, it is critical that the laptop is plugged in and not restarted while the update is taking place.

Important: Firmware updates have not been supplied for models that have reached end of development support with Lenovo. It is important to ensure that all corporate systems are within a support window with the manufacturer for this reason.

Technical Summary

Lenovo have issued firmware updates for the following CVE’s: CVE-2021-3970, CVE-2021-3971, CVE-2021-3972. Security researchers originally disclosed these updates on 11/10/2021, and Lenovo released fixes on 18/04/2022.

CVE-2021-3970 relates to a validation vulnerability within a variable named “LenovoVariable SMI Handler” which may allow an attacker with local access and elevated privileges to execute arbitrary code.

CVE-2021-3971 relates to a vulnerability within an older driver used during the manufacturing process that was mistakenly included within the BIOS image. This vulnerability could allow an attacker with elevated privileges to modify the firmware protection region by modifying an NVRAM variable.

CVE-2021-3972 relates to a vulnerability within an older driver used during the manufacturing process was mistakenly not deactivated which could allow an attacker with elevated privileges to modify secure boot settings by modifying an NVRAM variable.

Information on affected models with firmware updates available can be found here: Lenovo Notebook BIOS Vulnerabilities - Lenovo Support GB

Black Arrow Cyber Threat Briefing 15 April 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

• Cyber Security Is Getting Harder: More Threats, More Complexity, Fewer People

Splunk and Enterprise Strategy Group released a global research report that examines the security issues facing the modern enterprise. More than 1,200 security leaders participated in the survey, revealing they’ve seen an increase in cyber attacks while their teams are facing widening talent gaps.

According to the report, 65% of respondents say they have seen an increase in attempted cyber attacks. In addition, many have been directly impacted by data breaches and costly ransomware attacks, which have left security teams exhausted:

·       49% of organisations say they have suffered a data breach over the past two years, an increase from 39% a year earlier.

·       79% of respondents say they’ve encountered ransomware attacks, and 35% admit that one or more of those attacks led them to lose access to data and systems.

·       59% of security teams say they had to devote significant time and resources to remediation, an increase from 42% a year ago.

·       54% of respondents report that their business-critical applications have suffered from unplanned outages related to cyber security incidents on at least a monthly basis, with a median of 12 outages per year. The median time to recover from unplanned downtime tied to cyber security incidents is 14 hours. Respondents estimated the cost of this downtime averaged about $200,000 per hour.

·       64% of security professionals have stated that it’s challenging to keep up with new security requirements, up from 49% a year ago.

• Terrible Cloud Security Is Leaving the Door Open for Hackers. Here's What You're Doing Wrong

A rise in hybrid work and a shift to cloud platforms has changed how businesses operate - but it's also leaving them vulnerable to cyber attacks.

Cloud applications and services are a prime target for hackers because poor cyber security management and misconfigured services are leaving them exposed to the internet and vulnerable to simple cyber attacks.

Analysis of identity and access management (IAM) polices taking into account hundreds of thousands of users in 18,000 cloud environments across 200 organisations by cyber security researchers at Palo Alto Networks found that cloud accounts and services are leaving open doors for cyber criminals to exploit – and putting businesses and users at risk.

The global pandemic pushed organisations and employees towards new ways of remote and hybrid working, with the aid of cloud services and applications. While beneficial to businesses and employees, it also created additional cyber security risks – and malicious hackers know this.

• More Organisations Are Paying the Ransom. Why?

Most organisations (71%) have been hit by ransomware in 2021, and most of those (63%) opted for paying the requested ransom, the 2022 Cyberthreat Defense Report (CDR) by the CyberEdge Group has shown.

The research company says that possible explanations for the steady yearly rise of the percentage of organisations that decided to pay the ransom may include: the threat of exposing exfiltrated data, increased confidence for data recovery, and the fact that many organisations find that paying a ransom is significantly less costly than system downtime, customer disruption, and potential lawsuits.

“72% of ransom-paying victims recovered their data [in 2021], up from 49% in 2017. This increased confidence for successful data recovery is often factored into the ransom-paying decision,” the company noted.

Similarly, BakerHostatler’s 2022 Data Security Incident Response Report says that in ransomware incidents the US-based law firm was called in to manage in 2021, ransomware groups provided decryptors and stuck to their promise to not publish stolen data 97% of the time.

• Cyber Attack Puts City Firms on High Alert to Bolster Defences

Experts warn a combination of 'ignorance and arrogance' makes City executives vulnerable to attacks.

City firms on high alert for cyber attacks were sent a clear warning recently, bolstering concerns of the potential for breaches from Russia.

Ince Group, the London-listed law firm, last month fell prey to hackers who infiltrated its computer systems and stole confidential data. The company's security systems detected the intrusion on March 13, prompting the IT team to shut down servers to try and prevent widespread damage.

But soon after, the hackers demanded a ransom for stolen data and threatened to publish it on the dark web if Ince Group, which has clients in the shipping, energy and healthcare sectors, didn't pay up.

The incident has intensified worries of possible breaches after warnings that City firms could be targeted by Russian hackers following Putin’s invasion of Ukraine.

Julia O'Toole, chief executive of MyCena Security Solutions, says executives should be "very concerned" about any news of a cyber attack at a rival company.

• More Than 60% of Organisations Suffered a Breach in the Past 12 Months

Firms focus too narrowly on external attackers when it's insiders, third parties, and stolen assets that cause many breaches, new study shows.

The majority of companies — 63% — have suffered at least one breach in the past 12 months. The global average breach cost $2.4 million — a price tag that increases to $3.0 million for companies unprepared to respond to compromises.

The new data from Forrester Research, released on April 8 in a report titled "The 2021 State Of Enterprise Breaches," found that the number of breaches and the cost of breaches varied widely depending on the geographic location of the business and to what degree the organisation is prepared to respond to breaches. Companies in North America had the largest disparity between the haves and have-nots: While the average organisation required 38 days to find, eradicate, and recover from a breach, companies that failed to adequately prepare for security challenges took 62 days.

The difference in response resulted in a large difference in cost as well, with the average North American company paying $3.0 million to recover from a breach, a bill that rises to $4.0 million if the company suffered from a lack of incident-response preparation.

"The misalignment between the expectation and the reality of breaches has become very important," says Allie Mellen, an analyst with Forrester's Security and Risk group. "On a global scale, there is a big disparity of about $600,000 between those who are prepared to respond to a breach and those who are not."

• Account Takeover Poised to Surpass Malware as The No. 1 Security Concern

As most researchers and financial executives can attest, virtually all types of fraud have dramatically risen over the past two years. However, attackers taking over legitimate financial accounts have become even more of a favourite with cyber criminals than most fraud schemes.

Many major recent research reports have pointed out that account takeover (ATO), a form of identity theft where bad actors access legitimate bank accounts, change the account information and passwords, and hijack a real customer’s account, has skyrocketed since last year. According to Javelin Research’s annual "Identity Fraud Study: The Virtual Battleground" report, account takeover increased by 90% to an estimated $11.4 billion in 2021 when compared with 2020 — representing roughly one-quarter of all identity fraud losses last year.

Like many types of financial fraud, cyber thieves are betting on the fact that if they attempt to seize a large number of legitimate accounts, eventually they will get a payoff.

Account takeovers are a numbers game, the more accounts that an organisation has, the bigger their risk that some of them will be compromised.

Account takeovers often piggyback off of previous attacks, making these crimes a way for hackers to make the most out of stolen information. Diskin pointed out that account takeovers most commonly happen when a password is “taken from another data leak and reused for different accounts. But there are a variety of risky scenarios that can lead to compromise.”

• Security Research Reveals 42% Rise in New Ransomware Programs In 2021

Critical infrastructure in the crosshairs: operational technology vulnerabilities jump 88% .

Threat intelligence analysts at Skybox Research Lab uncovered a 42% increase in new ransomware programs targeting known vulnerabilities in 2021. The Silicon Valley cyber security company released its annual 2022 Vulnerability and Threat Trends Report, revealing how quickly cyber criminals capitalise on new security weaknesses – shrinking the window that organisations have to remediate vulnerabilities ahead of an attack.

With 20,175 new vulnerabilities published in 2021, Skybox Research Lab witnessed the most vulnerabilities ever reported in a single year. And these new vulnerabilities are just the tip of the iceberg. The total number of vulnerabilities published over the last 10 years reached 166,938 in 2021 — a three-fold increase over a decade. These cumulative vulnerabilities, piling up year after year, represent an enormous aggregate risk, and they’ve left organisations struggling with a mountain of cyber security debt. As the US Cybersecurity and Infrastructure Security Agency (CISA) highlights in its Top Routinely Exploited Vulnerabilities list, threat actors are routinely exploiting publicly disclosed vulnerabilities from years past.

The sheer volume of accumulated risks — hundreds of thousands or even millions of vulnerability instances within organisations — means they can’t possibly patch all of them. To prevent cyber security incidents, it is critical to prioritise exposed vulnerabilities that could cause the most significant disruption, then, apply appropriate remediation options including configuration changes or network segmentation to eliminate risk, even before patches are applied or in cases where patches aren’t available.

• Fraudsters Stole £58m with Remote Access Trojans (RATs) in 2021

2021 saw victims of Remote Access Tool (RAT) scams lose £58m in 2021, official UK police figures show.

RAT scams involve scammers taking control of a victim’s device, typically in order to access bank accounts.

Some 20,144 victims fell for this type of scam in 2021, averaging around £2800 stolen per incident.

Typically, RAT attacks begin with a victim being inundated with pop-ups claiming there is a problem with the computer. Users are often then asked to call a “hotline” number, when a scammer will persuade them to download a RAT.

RAT scams are often compared to the classic “tech support” scams. Modern RAT scams are typically more devious, however, with scammers often cold-calling their victims pretending to work for their bank and claiming that they need computer access to investigate a fraudulent transaction.

• As State-Backed Cyber Threats Grow, Here's How the World Is Reacting

With the ongoing conflict in Eurasia, cyber warfare is inevitably making its presence felt. The fight is not only being fought on the fields. There is also a big battle happening in cyberspace. Several cyber-attacks have been reported over the past months.

Notably, cyber attacks backed by state actors are becoming prominent. There have been reports of a rise of ransomware and other malware attacks such as Cyclops Blink, HermeticWiper, and BlackCat. These target businesses as well as government institutions and nonprofit organisations. There have been cases of several attempts to shut down online communications and IT infrastructure.

The ongoing list of significant cyber incidents curated by the Center for Strategic and International Studies (CSIS) shows that the number of major incidents in January 2022 is 100% higher compared to the same period in the previous year. With the recent activities in cyberspace impacted by the emergence of the geopolitical tumult in February, it is not going to be surprising to see an even more dramatic rise in the number of significant incidents.

• Q1 Reported Data Compromises Up 14% Over 2021

The Identity Theft Resource Center published a First Quarter 2022 Data Breach Analysis which found that Q1 of 2022 began with the highest number of publicly reported data compromises in the past three years.

Publicly reported data compromises totalled 404 through March 31, 2022, a 14 percent increase compared to Q1 2021.

This is the third consecutive year when the number of total data compromises increased compared to Q1 of the previous year. It also represents the highest number of Q1 data compromises since 2020.

• Europol Announces Operation to Hit Russian Sanctions-Evaders

European police have announced a major new operation designed to crack down on Russian oligarchs and businesses looking to circumvent sanctions.

Operation Oscar will run for at least a year as an umbrella initiative that will feature many separate investigations, Europol explained.

The policing organisation’s European Financial and Economic Crime Centre will work to exchange information and intelligence with partners and provide operational support in financial crime investigations.

A key focus appears to be on illicit flows of money, which Russian individuals and entities will be trying to move around the region in order to bypass sanctions imposed since President Putin’s invasion of Ukraine.

“Europol will centralise and analyse all information contributed under this operation to identify international links, criminal groups and suspects, as well as new criminal trends and patterns,” Europol said.

“Europol will further provide tailor-made analytical support to investigations, as well as operational coordination, forensics and technical expertise, and financial support to the relevant national authorities.”

Black Arrow Cyber Threat Briefing 08 April 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

• Nearly Two-Thirds of Ransomware Victims Paid Ransoms Last Year, Finds "2022 Cyberthreat Defense Report"

CyberEdge Group, a leading research and marketing firm serving the cyber security industry’s top vendors, announced the launch of its ninth annual Cyberthreat Defense Report (CDR). The award-winning CDR is the standard for assessing organisations’ security posture, gauging perceptions of information technology (IT) security professionals, and ascertaining current and planned investments in IT security infrastructure – across all industries and geographic regions.

A record 71% of organisations were impacted by successful ransomware attacks last year, according to the 2022 CDR, up from 55% in 2017. Of those that were victimised, nearly two-thirds (63%) paid the requested ransom, up from 39% in 2017.

• New Android Banking Malware Remotely Takes Control of Your Device

A new Android banking malware named Octo has appeared in the wild, featuring remote access capabilities that allow malicious operators to perform on-device fraud.

Octo is an evolved Android malware based on ExoCompact, a malware variant based on the Exo trojan that quit the cyber crime space and had its source code leaked in 2018.

The new variant has been discovered by researchers at ThreatFabric, who observed several users looking to purchase it on darknet forums.

https://www.bleepingcomputer.com/news/security/new-android-banking-malware-remotely-takes-control-of-your-device/

• Network Intrusion Detections Skyrocketing

A WatchGuard report shows a record number of evasive network malware detections with advanced threats increasing by 33%, indicating a higher level of zero day threats than ever before.

Researchers detected malware threats in EMEA at a much higher rate than other regions of the world in Q4 2021, with malware detections per Firebox at 49%, compared to Americas at 23% and APAC at 29%. The trajectory of network intrusion detections also continued its upward climb with the largest total detections of any quarter in the last three years and a 39% increase quarter over quarter.

Researchers suggest that this may be due to the continued targeting of old vulnerabilities as well as the growth in organisations’ networks. As new devices come online and old vulnerabilities remain unpatched, network security is becoming more complex.

https://www.helpnetsecurity.com/2022/04/08/network-malware-detections/

• Organisations Underestimating the Seriousness of Insider Threats

Imperva releases data that shows organisations are failing to address the issue of insider threats during a time when the risk is at its greatest.

New research, conducted by Forrester, found that 59% of incidents in EMEA organisations that negatively impacted sensitive data in the last 12 months were caused by insider threats, and yet 59% do not prioritise insider threats the way they prioritise external threats. Despite the fact that insider events occur more often than external ones, they receive lower levels of investment.

This approach is at odds with today’s threat landscape where the risk of malicious insiders has never been higher. The rapid shift to remote working means many employees are now outside the typical security controls that organisations employ, making it harder to detect and prevent insider threats.

Further, the Great Resignation is creating an environment where there is a higher risk of employees stealing data. This data could be stolen intentionally by people looking to help themselves in future employment, because they are disgruntled and want revenge, or it could be taken unintentionally when a careless employee leaves the business with important information.

• Watch Out for Phishing Emails from Genuine Mailing Lists, Following Mailchimp Hack

A Mailchimp hack means that you’ll want to be even more vigilant than usual about phishing emails. Attackers have taken a clever approach to making their emails appear genuine …

When you subscribe to an email list, there’s a decent chance that the emails you received are actually sent by a company called Mailchimp, rather than directly by the company itself. Mailchimp offers companies a range of tools that make it easy to manage email databases, and send marketing emails and newsletters.

Hackers managed to gain access to more than 100 Mailchimp customer accounts, giving them the ability to send emails that would appear to have come from any one of those businesses.

Users will need to be more vigilant when receiving emails and avoid clicking on links in emails, even if they appear genuine.

• SpringShell Attacks Target About One in Six Vulnerable Orgs

Roughly one out of six organisations worldwide that are impacted by the Spring4Shell zero-day vulnerability have already been targeted by threat actors, according to statistics from one cyber security company.

The exploitation attempts took place in the first four days since the disclosure of the severe remote code execution (RCE) flaw, tracked as CVE-2022-22965, and the associated exploit code.

According to Check Point, who compiled the report based on their telemetry data, 37,000 Spring4Shell attacks were detected over the past weekend alone.

• New Threat Group Underscores Mounting Concerns Over Russian Cyber Threats

Crowdstrike says Ember Bear is likely responsible for the wiper attack against Ukrainian networks and that future Russian cyber attacks might target the West.

As fears mount over the prospects of a “cyberwar” initiated by the Russian government, the number of identified Russian threat actors also continues to climb. Last week CrowdStrike publicly revealed a Russia-nexus state-sponsored actor that it tracks as Ember Bear.

CrowdStrike says that Ember Bear (also known as UAC-0056, Lorec53, Lorec Bear, Bleeding Bear, Saint Bear) is likely an intelligence-gathering adversary group that has operated against government and military organisations in eastern Europe since early 2021. The group seems “motivated to weaponize the access and data obtained during their intrusions to support information operations (IO) aimed at creating public mistrust in targeted institutions and degrading government ability to counter Russian cyber operations,” according to CrowdStrike intelligence.

Despite its state-sponsored Russia nexus, Ember Bear differs from its better-known kin such as Fancy Bear or Voodoo Bear because CrowdStrike can’t tie it to a specific Russian organisation. Its target profile, assessed intent, and technical tactics, techniques, and procedures (TTPs) are consistent with other Russian GRU cyber operations.

• Consumer Fraud Tripled in The Last Two Years

Reported cases of consumer fraud more than tripled in the years 2020-2021 from prior years, finds a new report by Accenture, presenting a growing challenge for public safety agencies to find new strategies to counter the trend.

The report compiled data from eight developed nations (Australia, Canada, France, Germany, Italy, Singapore, the United Kingdom, and the United States) on consumer fraud, defined as any fraud directly targeting citizens and excluding fraud targeting government agencies and companies. Reports of such fraud increased at an estimated 6.8% rate annually during 2013-2019 and then increased to a 22.5% annual growth rate yearly during 2020-2021 in parallel with the large shift of workers and consumers to digital channels and greater use of technology during the pandemic.

• Borat RAT: Multiple Threat of Ransomware, DDoS and Spyware

A new remote access trojan (RAT) dubbed "Borat" doesn't come with many laughs but offers bad actors a menu of cyberthreats to choose from.

RATs are typically used by cyber criminals to get full control of a victim's system, enabling them to access files and network resources and manipulate the mouse and keyboard. Borat does all this and also delivers features to enable hackers to run ransomware, distributed denial of service attacks (DDoS) and other online assaults and to install spyware, according to researchers at cyber security biz Cyble.

"The Borat RAT provides a dashboard to Threat Actors (TAs) to perform RAT activities and also has an option to compile the malware binary for performing DDoS and ransomware attacks on the victim's machine," the researchers wrote in a blog post, noting the malware is being made available for sale to hackers.

Borat – named after the character made famous by actor Sacha Baron Cohen in two comedy films – comes with the standard requisite of RAT features in a package that includes such functions as builder binary, server certificate and supporting modules.

• Bank Had No Firewall License, Intrusion or Phishing Protection – Guess the Rest

An Indian bank that did not have a valid firewall license, had not employed phishing protection, lacked an intrusion detection system and eschewed use of any intrusion prevention system has, shockingly, been compromised by criminals who made off with millions of rupees.

The unfortunate institution is called the Andra Pradesh Mahesh Co-Operative Urban Bank. Its 45 branches and just under $400 million of deposits make it one of India's smaller banks.

It certainly thinks small about security – at least according to Hyderabad City Police, which last week detailed an attack on the Bank that started with over 200 phishing emails being sent across three days in November 2021. At least one of those mails succeeded in fooling staff, resulting in the installation of a Remote Access Trojan (RAT).

Another technology the bank had chosen not to adopt was virtual LANs, so once the RAT went to work the attackers gained entry to the Bank's systems and were able to roam widely – even in its core banking application

• Global APT Groups Use Ukraine War for Phishing Lures

Security researchers have detected multiple APT campaigns leveraging Ukraine war-themed documents and news sources to lure victims into clicking on spear-phishing links.

Check Point Research said victim locations ranged from South America to the Middle East, with malware downloads designed to perform keylogging and screenshotting and execute commands.

The threat groups in question include El Machete, which is targeting the financial and government sectors in Nicaragua and Venezuela with malicious macro-laden Word documents containing articles on the war.

One of the docs was an article written by the Russian ambassador to Nicaragua titled: “Dark plans of the neo-Nazi regime in Ukraine.”

Another is Lyceum, an Iranian state-linked group targeting the energy sector with emails about war crimes in Ukraine that link to a malicious document hosted elsewhere. Its victims so far have been in Israel and Saudi Arabia, according to Check Point.

One email contained a link to an article from The Guardian hosted on the news-spot[.]live domain, alongside several malicious docs about the war.

• Paying Ransom Doesn’t Guarantee Data Recovery

OwnBackup announced the findings of a global survey conducted by Enterprise Strategy Group (ESG) that reveals a staggering 79% of respondent organisations have been targeted by ransomware within the past 12 months. Of those organisations, nearly three quarters said the attack was successful, meaning that it disrupted business operations.

Other key findings

·       Of the respondents that said their organisation paid a cyber ransom to regain access to data, applications, and/or systems after an attack, only 14% were able to recover all of their data.

·       87% of respondents who made ransom payments said that they experienced additional extortion attempts beyond the initial ransomware demand.

·       31% of respondent organisations targeted by ransomware indicated that application user and permission misconfigurations were the initial point of compromise.

·       87% of respondents are very or somewhat concerned about their backups being infected by ransomware attacks.

Black Arrow Cyber Advisory 07/04/2022 – VMware provides patches for critical vulnerabilities in multiple products.

Executive Summary

VMware is a large supplier of virtualisation products which are used to run a variety of different services. They announced on 06/04/2022 that updates have been released for multiple products in their range to address different vulnerabilities. Some of these vulnerabilities have been marked as “critical”, including Spring4Shell due to the ability for a malicious actor to remotely execute code.

What’s the risk to me or my business?

As VMware are one of the primary suppliers of virtual infrastructure, it is highly likely that some business services will be hosted on machines running VMware software. There are a range of different critical and medium vulnerabilities being patched with these updates, including Spring4Shell, which CISA are now stating is being actively exploited.

What can I do?

As patches have been released, it is important that these are applied as soon as possible, particularly as some of the vulnerabilities are now being actively exploited.

Discuss with you Managed Service Provider (MSP) whether any of your devices or services are impacted, and when they can expect to be patched. While VMware has supplied workaround to help mitigate the issue if it cannot be immediately patched, it is strongly noted that the work arounds do not remove the vulnerabilities and may introduce additional unforeseen issues.

Black Arrow Cyber Advisory – Spring4Shell Remote Code Execution Vulnerability - updated 05/04/2022 under active exploitation

Update 05/04/2022: CISA have now confirmed that there is Active Exploitation of Critical Spring4Shell Vulnerability. It is recommended that patches are applied as soon as possible.

Executive Summary

Spring Core is a popular framework used for creating Java-based enterprise applications. Spring4Shell is a critical zero-day bug within this framework, that allows attackers to remotely execute code on affecting systems running certain, non-default configurations. Due to the popularity, Spring Core may be found within many java-based enterprise applications, and Java, is an almost ubiquitous software that’s found in billions of devices across the globe, from the enterprise to the home. The bug has been deemed “Critical”, primarily due to the remote root or administrator capabilities of an attacker if exploited.

This bug is currently receiving a large quantity of media attention. While we do not believe that this issue is of major concern at this time, it is something that is important to be aware of. We will continue to monitor and upgrade our advisory if we deem appropriate.

What’s the risk to me or my business?

While the use of the Spring Core framework is very popular, this exploit appears to be only exploitable in certain configurations. The bug is not noted to be widely exploited at this time, however attackers will leverage anything they can when compromising a network, and it may only be a matter of time now the bug has been made public. The risk will primarily come from a failure to patch the flaw, which may be easy to overlook.

What can I do?

A patch has been released for the Spring Framework. The bug affects versions 5.3.0 to 5.3.17, 5.2.0-5.2.19 and all other older versions. This bug will be present in any java application made using the Spring Framework.

Discuss with you Managed Service Provider (MSP) whether any of your devices or services are impacted, and when they can expect to be patched. Equally, keeping devices at home or elsewhere up to date is an important step to mitigation, both for your professional and private life.

It is advised that network administrators patch as soon as possible.

We are continuing to monitor this and will provide updates when more information is available.

Technical Summary

The bug, tracked as CVE-2022-22965, was first reported to VMware late Tuesday evening, 29/03/2022. Investigation and analysis into the issue was being conducted with the aim for an emergency release on Thursday, 31/03/2022 however details were leaked in full online prior to this. The vendor has detailed that if the application was deployed using the default configuration, then it should not be exploitable, however due to the nature of the vulnerability there may be more unknown ways to exploit it. Further technical details will be supplied when more details are released.

Black Arrow Cyber Advisory 05/04/2022 – Sophos Remote Code Execution Vulnerability identified.

Executive Summary

A critical flaw has been discovered in Sophos Firewall, allowing for remote code execution within the User Portal and Webadmin areas of the product. The bug impacts Sophos Firewall Network Access Control (NAC) systems, running versions v18.5 MR3 [18.5.3] and lower. The bug, achieving a 9.8 on the Common Vulnerability Scoring System (CVSS), allows attackers to remotely execute code on the device.

What’s the risk to my business?

Due to the severity of the bug, and the ability for attackers to gain remote code execution on a critical perimeter defence, the risk to businesses operating Sophos Firewalls is high, however if the device is configured using device access best practices as recommended by Sophos, then the bug is mitigated.

What can I do?

The bug has been reported, and a patch has been issued. Businesses operating these devices are urged to implement as soon as possible. Note: If “Allow automatic installation of hotfixes” feature is enabled, then the hotfixes should have already been installed.

Additional mitigations of ensuring that the User Portal and Webadmin portal are not exposed to the Wide Area Network (WAN) should be applied if not already in place following device access best practices issued by Sophos.

Technical Summary

Sophos have issued a patch for bug CVE-2022-1040, which was disclosed on 25/03/2022. Older, unsupported versions will require an upgrade in order to apply this fix. Follow Sophos Firewall: Verify if the hotfix for CVE-2022-1040 is applied to confirm that the hotfix has been applied. No further technical details on the bug are available at this time.

Black Arrow Cyber Threat Briefing 01 April 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

• One Tenth of UK Staff Bypass Corporate Security

A new study from Cisco has found that a tenth of UK employees actively circumvent their organisation’s security measures.

The network technology company polled over 1000 UK professionals working for organisations that allow hybrid working, in order to better understand the potential security risks of the modern, flexible workplace.

The research has revealed that many hybrid workers do not see cyber security as their responsibility, with many actively finding workarounds or engaging in risky behaviours such as password reuse.

19% of employees said they reuse passwords for multiple accounts and applications, with only 15% using password managers.

The problem seems to stem from user friction in existing security measures. Only 44% of survey participants said they found it easy to securely access their IT equipment.

A majority said they would be willing to use biometric authentication, a reflection of how enterprise security is still catching up to consumer functionality.

https://www.itsecurityguru.org/2022/03/28/one-tenth-of-uk-staff-bypass-corporate-security/

• Majority Of Data Security Incidents Caused by Insiders

New research from Imperva has revealed that 70% of EMEA organisations have no insider risk strategy, despite 59% of data security incidents being caused by employees.

The shocking revelation comes as part of a wider study carried out by Forrester: Insider Threats Drive Data Protection Improvements. The study involved interviewing 150 security and IT professionals in EMEA.

An insider threat is defined by Imperva as originating from “inappropriate use of legitimate authorised user accounts” by either their rightful owner or a threat actor who has managed to compromise them.

The study found that insider threats were responsible for 59% of incidents impacting sensitive data in the past 12 months. This supports a previous Imperva analysis of the most significant breaches of the past five years, revealing that 24% were caused by either human error or compromised credentials.

https://www.itsecurityguru.org/2022/04/01/majority-of-data-security-incidents-caused-by-insiders/

• One-Third of UK Firms Suffer a Cyber Attack Every Week

Cyber attacks and related incidents at UK organisations continue their seemingly unstoppable upward trajectory, with new statistics from the Department for Digital, Culture, Media and Sport (DCMS) revealing that 31% of businesses and 26% of charity organisations now experience incidents on a weekly basis.

The data, contained in the annual cyber security breaches survey report, paints a stark picture of the scale of the threat facing the average organisation, and the urgent need to boost standards and defences.

It is vital that every organisation takes cyber security seriously as more and more business is done online and we live in a time of increasing cyber risk.  No matter how big or small your organisation is, you need to take steps to improve digital resilience.

Some 20% of businesses and 19% of charities said they had experienced a negative outcome as a direct consequence of an attack. The average cost of an attack, spread out across all organisations, now works out at £4,200, or £19,400 if only medium and large businesses are considered, although there is probably a vast amount of under-reporting, so the true figures are certainly higher.

Meanwhile, 35% of businesses and 38% of charities said they had experienced some kind of negative impact during the incident, such as service downtime.

• Russia's Cyber Criminals Fear Sanctions Will Erase Their Wealth

Punitive economic sanctions over Russia's invasion of Ukraine had crooks discussing the best ways to adapt to the new reality.

Members of Russian-language underground forums are not immune to the latest news. Russia's invasion of Ukraine and subsequent economic sanctions against Moscow got forum users to discuss how to live in this new world they find themselves in.

According to a report by the Digital Shadows Photon team, dark web forums are teeming with questions on how to ensure the safety of funds held in Russia-based accounts.

One user sought advice on what to do with dollars held in a Russian bank, with others suggesting converting dollars to rubles for a few months.

"I hope you were joking about [holding the funds in rubles for] half a year? After half a year, your rubles will only be good for lighting a fire, they will not be good for anything else," a forum user responded.

• 86% Of Organisations Believe They Have Suffered a Nation-State Cyber Attack

A new study by Trellix and the Center for Strategic and International Studies (CSIS) has revealed that 86% of organisations believe they have fallen victim to a nation-state cyber attack.

The research surveyed 800 IT decision-makers in Australia, France, Germany, India, Japan, the UK and US.

It has also been revealed that 92% of respondents have faced, or suspect they have faced, a nation-state backed cyber attack in the past 18 months, or anticipate one in the future.

Russia and China were identified as the most likely suspects behind said attacks. 39% of organisations that believe they have been hit with a nation-state cyber attack believe Russia were the perpetrators.

• Multiple Hacking Groups Are Using the War in Ukraine as A Lure in Phishing Attempts

Hostile hacking groups are exploiting Russia's invasion of Ukraine to carry out cyber attacks designed to steal login credentials, sensitive information, money and more from victims around the world.

According to cyber security researchers at Google's Threat Analysis Group (TAG), government-backed hackers from Russia, China, Iran and North Korea, as well as various unattributed groups and cyber criminal gangs, are using various themes related to the war in Ukraine to lure people into becoming victims of cyber attacks.

In just the last two weeks alone, Google has seen several hacking groups looking to take advantage of the war to fulfil their malicious aims, whether that's stealing information, stealing money, or something else.

• 4 Ways Attackers Target Humans to Gain Network Access

Since the day we started receiving email, we hope that our antivirus or endpoint protection software alerts us to problems. In reality, it often does not. When technology fails, it’s likely because the attacker made an end run around it by targeting humans. Here are four ways they do it:

1. The targeted human attack

2. Fraudulent wire transfer email

3. Tricking users into handing over credentials

4. Bypassing multi-factor authentication

• Security Incidents Reported to FCA Surge 52% in 2021

The number of cyber security incidents reported to the UK’s financial regulator surged by over 50% last year after a significant increase in cyber-attacks, according to new figures from Picus Security.

The security vendor submitted Freedom of Information (FoI) requests to the Financial Conduct Authority (FCA) to compile its latest report, Cyber Security Incidents in the UK Financial Sector.

The 52% year-on-year increase in “material” security incidents reported to the FCA seems to have been driven by cyber-attacks, which comprised nearly two-thirds (65%) of these reports.

Picus Security claimed that the rest are likely explained by “system and process failures and employee errors.”

In addition, a third of incident reports were about corporate or personal data breaches, and a fifth involved ransomware.

Picus Security explained that to qualify as a material incident, there needs to have been a significant loss of data, operational IT outages, unauthorized IT access, and/or an impact on a large number of customers.

https://www.infosecurity-magazine.com/news/security-incidents-reported-fca/

• NCSC Suggests Rethinking Russian Supply Chain Risks

The National Cyber Security Centre (NCSC) of the UK has urged organisations to reconsider the risks associated with “Russian-controlled” parts of their supply chains.

Ian Levy, technical director of the NCSC argued that “Russian law already contains legal obligations on companies to assist the Russian Federal Security Service (FSB), and the pressure to do so may increase in a time of war. We also have hacktivists on each side, further complicating matters, so the overall risk has materially changed.”

Levy has suggested that while there is currently nothing to suggest that the Russian state intends to force commercial providers to sabotage UK interests, that doesn’t mean it will not happen in the future.

• 25% Of Workers Lost Their Jobs in The Past 12 Months After Making Cyber Security Mistakes: Report

For business leaders, there is never a good time for their employees to make mistakes on the job. This is especially true now for workers who have anything to do with the cyber security of their companies and organisations. Given the growing risks of cyber attacks across the world and the increased threats posed by Russia in the aftermath of their invasion of Ukraine, these are certainly perilous times.

Indeed, a new study released by email security company Tessian found that one in four employees (26%) lost their job in the last 12 months after making a mistake that compromised their company’s security.

According to the second edition of Tessian’s Psychology of Human Error report, people are falling for more advanced phishing scams—and the business stakes for mistakes are much higher.

The study also found that:

• Two-fifths (40%) of employees sent an email to the wrong person, with almost one-third (29%) saying their business lost a client or customer because of the error

• Over one-third (36%) of employees have made a mistake at work that compromised security and fewer are reporting their mistakes to IT.

https://www.forbes.com/sites/edwardsegal/2022/03/29/25-of-workers-lost-their-jobs-in-the-past-12-months-after-making-cybersecurity-mistakes-report/?sh=d47cdfa49b26

• Attackers Compromise 94% of Critical Assets Within Four Steps of Initial Breach

New research from XM Cyber analysing the methods, attack paths, and impacts of cyber attacks has discovered that attackers can compromise 94% of critical assets within just four steps of initial breach points. The hybrid cloud security company’s Attack Path Management Impact Report incorporates insights from nearly two million endpoints, files, folders, and cloud resources throughout 2021, highlighting key findings on attack trends and techniques impacting critical assets across on-prem, multi-cloud, and hybrid environments.

The findings showed that 75% of an organisation’s critical assets are open to compromise in their current security state, while 73% of the top attack techniques used last year involved mismanaged or stolen credentials. Just over a quarter (27%) of most common attack techniques exploited a vulnerability or misconfiguration.

• UK Spy Chief Warns Russia Looking for Cyber Targets

A UK intelligence chief warned that the Kremlin is hunting for cyber targets and bringing in mercenaries to shore up its stalled military campaign in Ukraine.

Jeremy Fleming, who heads the GCHQ electronic spy agency, praised Ukrainian President Volodymyr Zelenskyy’s “information operation” for being highly effective at countering Russia’s massive disinformation drive spreading propaganda about the war.

While there were expectations that Russia would launch a major cyber attack as part of its military campaign, Fleming said such a move was never a central part of Moscow’s standard playbook for war.

“That’s not to say that we haven’t seen cyber in this conflict. We have — and lots of it,” Fleming said in a speech in Canberra, Australia, according to a transcript released in London on Wednesday.

He said GCHQ’s National Cyber Security Centre has picked up signs of “sustained intent” by Russia to disrupt Ukrainian government and military systems.

“We’ve seen what looks like some spillover of activity affecting surrounding countries,” Fleming said. “And we’ve certainly seen indicators which suggest Russia’s cyber actors are looking for targets in the countries that oppose their actions.”

He provided no further details. He said the UK and other Western allies will continue to support Ukraine in beefing up its cyber security defences.

Black Arrow Cyber Advisory – Apple releases patches for actively exploited zero-days across Mac, iPhone and iPad

Executive Summary

Apple has released security updates yesterday, 31/03/2022, in response to two actively exploited zero-day vulnerabilities affecting iPhones, iPads and Mac Computers. One vulnerability allows attackers to execute malicious code with privileged access, while the other allows attackers to read privileged memory on the device. Apple has only released limited information on the vulnerabilities at this time.

What’s the risk to me or my business?

These bugs have been confirmed to be actively exploited, and it affects all users of iPhones, iPads and Mac Computers. The risk will primarily come from a failure to patch the critical vulnerability.

What can I do?

Patches have been released for both bugs by Apple within MacOS 12.3.1, iPad OS 15.4.1 and iOS 15.4.1. It is strongly advised that these updates are applied as soon as possible.

Technical Summary

There are two separate bugs tracked as CVE-2022-22675 and CVE-2022-22674.

CVE-2022-22675 affects MacOS versions prior to 12.3.1, iPadOS prior to 15.4.1 and iOS versions prior to 15.4.1. This bug relates to AppleAVD, which is used to decode certain media files. This vulnerability allows an application to execute arbitrary code with kernel privileges through an out of bounds write issue. Apple has not provided any further details on this specific vulnerability.

CVE-2022-22674 affects MacOS versions prior to 12.3.1. This bug specifically relates to the Intel Graphics Driver so is unlikely to affect M1 devices, but this has not been confirmed by Apple. This bug allows an application to read kernel memory through an out-of-bounds read issue. The patch addresses this issue with improved input validation. Apple has not provided any further details on this specific vulnerability.

Need help understanding your gaps, or just want some advice? Get in touch with us.

Black Arrow Cyber Advisory – Spring4Shell Remote Code Execution Vulnerability

Executive Summary

Spring Core is a popular framework used for creating Java-based enterprise applications. Spring4Shell is a critical zero-day bug within this framework, that allows attackers to remotely execute code on affecting systems running certain, non-default configurations. Due to the popularity, Spring Core may be found within many java-based enterprise applications, and Java, is an almost ubiquitous software that’s found in billions of devices across the globe, from the enterprise to the home. The bug has been deemed “Critical”, primarily due to the remote root or administrator capabilities of an attacker if exploited.

This bug is currently receiving a large quantity of media attention. While we do not believe that this issue is of major concern at this time, it is something that is important to be aware of. We will continue to monitor and upgrade our advisory if we deem appropriate.

What’s the risk to me or my business?

While the use of the Spring Core framework is very popular, this exploit appears to be only exploitable in certain configurations. The bug is not noted to be widely exploited at this time, however attackers will leverage anything they can when compromising a network, and it may only be a matter of time now the bug has been made public. The risk will primarily come from a failure to patch the flaw, which may be easy to overlook.

What can I do?

A patch has been released for the Spring Framework. The bug affects versions 5.3.0 to 5.3.17, 5.2.0-5.2.19 and all other older versions. This bug will be present in any java application made using the Spring Framework.

Discuss with you Managed Service Provider (MSP) whether any of your devices or services are impacted, and when they can expect to be patched. Equally, keeping devices at home or elsewhere up to date is an important step to mitigation, both for your professional and private life.

It is advised that network administrators patch as soon as possible.

We are continuing to monitor this and will provide updates when more information is available.

Technical Summary

The bug, tracked as CVE-2022-22965, was first reported to VMware late Tuesday evening, 29/03/2022. Investigation and analysis into the issue was being conducted with the aim for an emergency release on Thursday, 31/03/2022 however details were leaked in full online prior to this. The vendor has detailed that if the application was deployed using the default configuration, then it should not be exploitable, however due to the nature of the vulnerability there may be more unknown ways to exploit it. Further technical details will be supplied when more details are released.

Black Arrow Cyber Threat Briefing 25 March 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

• Morgan Stanley Client Accounts Breached in Social Engineering Attacks

Morgan Stanley Wealth Management says some of its customers had their accounts compromised in social engineering attacks.

The account breaches were the result of vishing (aka voice phishing), a social engineering attack where scammers impersonate a trusted entity (in this case Morgan Stanley) during a voice call to convince their targets into revealing sensitive information such as banking or login credentials.

The company said in a notice sent to affected clients that, "on or around February 11, 2022," a threat actor impersonating Morgan Stanley gained access to their accounts after tricking them into providing their Morgan Stanley Online account info.

After successfully breaching their accounts, the attacker also electronically transferred money to their own bank account by initiating payments using the Zelle payment service.

• Ransomware Is Scary, But Another Scam Is Costing Victims Much, Much More

Business email compromise (BEC) remains the biggest source of financial losses, which totalled $2.4 billion in 2021, up from an estimated $1.8 billion in 2020, according to the Federal Bureau of Investigation's (FBI) Internet Crime Center (IC3).

The FBI says in its 2021 annual report that Americans last year lost $6.9 billion to scammers and cyber criminals through ransomware, BEC, and cryptocurrency theft related to financial and romance scams. In 2020, that figure stood at $4.2 billion.

Last year, FBI's Internet Crime Complaint Center (IC3) received 847,376 complaints about cybercrime losses, up 7% from 791,790 complaints in 2020.

BEC has been the largest source of fraud for several years despite ransomware attacks grabbing most headlines.

• Phishing Kits Constantly Evolve to Evade Security Software

Modern phishing kits sold on cybercrime forums as off-the-shelf packages feature multiple, sophisticated detection avoidance and traffic filtering systems to ensure that internet security solutions won’t mark them as a threat.

Fake websites that mimic well-known brands are abundant on the internet to lure victims and steal their payment details or account credentials.

Most of these websites are built using phishing kits that feature brand logos, realistic login pages, and in cases of advanced offerings, dynamic webpages assembled from a set of basic elements.

• Ransomware Payment Demands Rose Dramatically in 2021

Ransomware attackers demanded dramatically higher ransom fees last year, and the average ransom payment rose by 78% to $541,010, according to data from incident response (IR) cases investigated by Palo Alto Networks Unit 42.

IR cases by Unit 42 also saw a whopping 144% increase in ransom demands, to $2.2 million. According to the report, the most victimised sectors were professional and legal services, construction, wholesale and retail, healthcare, and manufacturing.

Cyber extortion spiked, with 85% of ransomware victims — some 2, 556 organisations — having their data dumped and exposed on leak sites, according to the "2022 Unit 42 Ransomware Threat Report."

Conti led the ransomware attack volume, representing some one in five cases Unit 42 investigated, followed by REvil, Hello Kitty, and Phobos.

• 7 Suspected Members of LAPSUS$ Hacker Gang, aged 16 to 21, Arrested in UK

The City of London Police has arrested seven teenagers between the ages of 16 and 21 for their alleged connections to the prolific LAPSUS$ extortion gang that's linked to a recent burst of attacks targeting NVIDIA, Samsung, Ubisoft, LG, Microsoft, and Okta.

"The City of London Police has been conducting an investigation with its partners into members of a hacking group," Detective Inspector, Michael O'Sullivan, said in a statement shared with The Hacker News. "Seven people between the ages of 16 and 21 have been arrested in connection with this investigation and have all been released under investigation. Our enquiries remain ongoing."

The development, which was first disclosed by BBC News, comes after a report from Bloomberg revealed that a 16-year-old Oxford-based teenager is the mastermind of the group. It's not immediately clear if the minor is one among the arrested individuals. The said teen, under the online alias White or Breachbase, is alleged to have accumulated about $14 million in Bitcoin from hacking.

• Here's How Fast Ransomware Encrypts Files

Forty-two minutes and 54 seconds: that's how quickly the median ransomware variant can encrypt and lock out a victim from 100,000 of their files.

The data point came from Splunk's SURGe team, which analysed in its lab how quickly the 10 biggest ransomware strains — Lockbit, REvil, Blackmatter, Conti, Ryuk, Avaddon, Babuk, Darkside, Maize, and Mespinoza — could encrypt 100,000 files consisting of some 53.93 gigabytes of data. Lockbit won the race, with speeds of 86% faster than the median. One Lockbit sample was clocked at encrypting 25,000 files per minute.

Splunk's team found that ransomware variants are all over the map speed-wise, and the underlying hardware can dictate their encryption speeds.

• HEAT Attacks: A New Class of Cyber Threats Organisations Are Not Prepared For

Web malware (47%) and ransomware (42%) now top the list of security threats that organisations are most concerned about. Yet despite the growing risks, just 27% have advanced threat protection in place on every endpoint device that can access corporate applications and resources.

This is according to research published by Menlo Security, exploring what steps organisations are taking to secure themselves in the wake of a new class of cyber threats – known as Highly Evasive Adaptive Threats (HEAT).

As employees spend more time working in the browser and accessing cloud-based applications, the risk of HEAT attacks increases. Almost two-thirds of organisations have had a device compromised by a browser-based attack in the last 12 months. The report suggests that organisations are not being proactive enough in mitigating the risk of these threats, with 45% failing to add strength to their network security stack over the past year. There are also conflicting views on the most effective place to deploy security to prevent advanced threats, with 43% citing the network, and 37% the cloud.

• The Cyber Warfare Predicted in Ukraine May Be Yet to Come

In the build-up to Russia’s invasion of Ukraine, the national security community braced for a campaign combining military combat, disinformation, electronic warfare and cyber attacks. Vladimir Putin would deploy devastating cyber operations, the thinking went, to disable government and critical infrastructure, blind Ukrainian surveillance capabilities and limit lines of communications to help invading forces. But that’s not how it has played out. At least, not yet.

The danger is that as political and economic conditions deteriorate, the red lines and escalation judgments that kept Moscow’s most potent cyber capabilities in check may adjust. Western sanctions and lethal aid support to Ukraine may prompt Russian hackers to lash out against the west. Russian ransomware actors may also take advantage of the situation, possibly resorting to cyber crime as one of the few means of revenue generation.

• The Three Russian Cyber Attacks the West Most Fears

The UK's cyber authorities are supporting the White House's calls for "increased cyber-security precautions", though neither has given any evidence that Russia is planning a cyber-attack.

Russia has previously stated that such accusations are "Russophobic".

However, Russia is a cyber-superpower with a serious arsenal of cyber-tools, and hackers capable of disruptive and potentially destructive cyber-attacks.

Ukraine has remained relatively untroubled by Russian cyber-offensives but experts now fear that Russia may go on a cyber-offensive against Ukraine's allies.

"Biden's warnings seem plausible, particularly as the West introduced more sanctions, hacktivists continue to join the fray, and the kinetic aspects of the invasion seemingly don't go to plan," says Jen Ellis, from cyber-security firm Rapid7.

This article from the BCC outlines the hacks that experts most fear, and they are repeats of things we have already seen coming out of Russia, only potentially a lot more destructive this time around.

• Do These 8 Things Now to Boost Your Security Ahead of Potential Russian Cyber Attacks

The message comes as the US Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) ramp up warnings about Russian hacking of everything from online accounts to satellite broadband networks. CISA's current campaign is called Shields Up, which urges all organisations to patch immediately and secure network boundaries. This messaging is being echoed by UK and other Western Cyber authorities:

The use of Multi-Factor Authentication (MFA) is being very strongly advocated. The White House and other agencies both sides of the Atlantic also urged companies to take seven other steps:

• Deploy modern security tools on your computers and devices to continuously look for and mitigate threats

• Make sure that your systems are patched and protected against all known vulnerabilities, and change passwords across your networks so that previously stolen credentials are useless to malicious actors

• Back up your data and ensure you have offline backups beyond the reach of malicious actors

• Run exercises and drill your emergency plans so that you are prepared to respond quickly to minimize the impact of any attack

• Encrypt your data so it cannot be used if it is stolen

• Educate your employees to common tactics that attackers will use over email or through websites

• Work with specialists to establish relationships in advance of any cyber incidents.

• Cyber Crime Victims Suffered Losses of Over $6.9B in 2021 in the US Alone

The FBI's Internet Crime Complaint Center (IC3) reported a record-breaking year for 2021 in the number of complaints it received, among which business email compromise (BEC) attacks made up the majority of incidents.

IC3 handled 847,376 complaint reports last year — an increase of 7% over 2020 — which mainly revolved around phishing attacks, nonpayment/nondelivery scams, and personal data breaches. Overall, losses amounted to more than $6.9 billion.

BEC and email account compromises ranked as the No. 1 attack, accounting for 19,954 complaints and losses of around $2.4 billion.

"In 2021, heightened attention was brought to the urgent need for more cyber incident reporting to the federal government. Cyber incidents are in fact crimes deserving of an investigation, leading to judicial repercussions for the perpetrators who commit them," Paul Abbate, deputy director of the FBI wrote in the IC3's newly published annual report.

• Expanding Threat Landscape: Cyber Criminals Attacking from All Sides

Research from Trend Micro warns of spiralling risk to digital infrastructure and remote workers as threat actors increase their rate of attack on organisations and individuals.

“Attackers are always working to increase their victim count and profit, whether through quantity or effectiveness of attacks,” said Jon Clay, VP of threat intelligence at Trend Micro.

“Our latest research shows that while Trend Micro threat detections rose 42% year-on-year in 2021 to over 94 billion, they shrank in some areas as attacks became more precisely targeted.”

Ransomware attackers are shifting their focus to critical businesses and industries more likely to pay, and double extortion tactics ensure that they are able to profit. Ransomware-as-a-service offerings have opened the market to attackers with limited technical knowledge – but also given rise to more specialisation, such as initial access brokers who are now an essential part of the cybercrime supply chain.

Threat actors are also getting better at exploiting human error to compromise cloud infrastructure and remote workers. Trend Micro detected and prevented 25.7 million email threats in 2021 compared to 16.7 million in 2020, with the volume of blocked phishing attempts nearly doubling over the period. Research shows home workers are often prone to take more risks than those in the office, which makes phishing a particular risk.

Black Arrow Cyber Threat Briefing 18 March 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

Guernsey Cyber Security Warning for Islanders and Businesses

There has been a rise in cyber-attacks since the war in Ukraine began, according to the States of Guernsey and a cyber-security firm.

The States said: "We have seen a noticeable increase in the number of phishing emails since the war began."

The Channel Islands see more than 10 million cyber attacks every month, according to research by Guernsey firm Black Arrow Cyber Consulting.

It encouraged vigilance, as the islands are not immune to these attacks.

A States spokesman said: "The whole community needs to remain vigilant against such emails, which are designed to appear to be from reputable sources in order to dupe people into providing personal information or access to their device via the clicking of a link."

Bruce McDougall, from Black Arrow Cyber Consulting, said: "Criminals don't let a good opportunity go to waste. So they're conducting scams encouraging people to make false payments in the belief they're collecting for charities."

CISOs Face 'Perfect Storm' Of Ransomware and State-Supported Cyber Crime

As some nations turn a blind eye, defence becomes life-or-death matter

With ransomware gangs raiding network after network, and nation states consciously turning a blind eye to it, today's chief information security officers are caught in a "perfect storm," says Cybereason CSO Sam Curry.

"There's this marriage right now of financially motivated cyber crime that can have a critical infrastructure and economic impact," Curry said during a CISO roundtable hosted by his endpoint security shop. "And there are some nation states that do what we call state-ignored sanctioning," he continued, using Russia-based REvil and Conti ransomware groups as examples of criminal operations that benefit from their home governments looking the other way. 

"You get the umbrella of sovereignty, and you get the free license to be a privateer in essence," Curry said. "It's not just an economic threat. It's not just a geopolitical threat. It's a perfect storm."

It's probably not a huge surprise to anyone that destructive cyber attacks keep CISOs awake at night. But as chief information security officers across industries — in addition to Curry, the four others on the roundtable spanned retail, biopharmaceuticals, electronics manufacturing, and a cruise line — have watched threats evolve and criminal gangs mature, it becomes a battle to see who can innovate faster; the attackers or the defenders.

Four Key Risks Exacerbated by Russia’s Invasion of Ukraine

Russia’s invasion of Ukraine has altered the emerging risk landscape, and it requires enterprise risk management (ERM) leaders to reassess previously established organisational risk profiles in at least four key areas, according to Gartner.

“Russia’s invasion of Ukraine has increased the velocity of many risks we have tracked on a quarterly basis in our Emerging Risks survey,” said Matt Shinkman, VP with the Gartner Risk and Audit Practice.

“As ERM leaders reassess their organisational risk models, they must also ensure a high frequency of communication with the C-Suite as to the critical changes that require attention now.”

There are four major areas of risk that ERM leaders should continually monitor and examine their mitigation strategies as part of a broader aligned assurance approach as the war continues: Talent Risk, Cyber Security Risk, Financial Risk and Supply Chain Risk

These Four Types of Ransomware Make Up Nearly Three-Quarters of Reported Incidents

Any ransomware is a cyber security issue, but some strains are having more of an impact than others.

Ransomware causes problems no matter what brand it is, but some forms are noticeably more prolific than others, with four strains of the malware accounting for a combined total of almost 70% of all attacks.

According to analysis by cyber security company Intel 471, the most prevalent ransomware threat towards the end of 2021 was LockBit 2.0, which accounted for 29.7% of all reported incidents. Recent victims of LockBit have included Accenture and the French Ministry of Justice. 

Almost one in five reported incidents involved Conti ransomware, famous for several incidents over the past year, including an attack against the Irish Healthcare Executive. The group recently had chat logs leaked, providing insights into how a ransomware gang works. PYSA and Hive account for one in 10 reported ransomware attacks each.

"The most prevalent ransomware strain in the fourth quarter of 2021 was LockBit 2.0, which was responsible for 29.7% of all reported incidents, followed by Conti at 19%, PYSA at 10.5% and Hive at 10.1%," said the researchers.

Critical Infrastructure Threat as Ransomware Groups Target 'Enemies of Russia'

The cyber crime underground has fractured into pro-Ukraine and pro-Russia camps, with the latter increasingly focused on critical national infrastructure (CNI) targets in the West, according to a new report from Accenture.

The consulting giant’s Accenture Cyber Threat Intelligence (ACTI) arm warned that the ideological schism could spell mounting risk for Western organisations as pro-Kremlin criminal groups adopt quasi-hacktivist tactics to choose their next victims.

Organisations in the government, media, finance, insurance, utilities and resources sectors should be braced for more attacks, said ACTI.

Cyber Insurance War Exclusions Loom Amid Ukraine Crisis

An expanding threat landscape is testing the limits of cyber insurance coverage.

The industry experienced a rapid maturation over the past three years as enterprises required a broader umbrella of insurance coverage to combat increasing cyber risks. While demands and premiums continue to rise, one recent area of contention involves war and hostile acts, an exclusion that's becoming harder to categorize.

A judgment in December, coupled with the Russian invasion last month that posed potential cyber retaliations to Ukraine allies, highlighted shortcomings in insurance policies when it comes to cyber conflicts.

Zelenskyy Deepfake Crude, But Still Might Be a Harbinger of Dangers Ahead

Several deepfake video experts called a doctored video of Ukrainian President Volodymyr Zelenskyy that went viral this week before social media platforms removed it a poorly executed example of the form, but nonetheless damaging.

Elements of the Zelenskyy deepfake — which purported to show him calling for surrender — made it easy to debunk, they said. But that won’t always be the case.

Cyber Crooks’ Political In-Fighting Threatens the West

They’re choosing sides in the Russia-Ukraine war, beckoning previously shunned ransomware groups and thereby reinvigorating those groups’ once-diminished power.

A rift has formed in the cyber crime underground: one that could strengthen, rather than cripple, the cyber-onslaught of ransomware.

According to a report, ever since the outbreak of war in Ukraine, “previously coexisting, financially motivated threat actors divided along ideological factions.”

“Pro-Ukrainian actors are refusing to sell, buy, or collaborate with Russian-aligned actors, and are increasingly attempting to target Russian entities in support of Ukraine,” wrote researchers from Accenture’s Cyber Threat Intelligence (ACTI). “However, pro-Russian actors are increasingly aligning with hacktivist-like activity targeting ‘enemies of Russia,’ especially Western entities due to their claims of Western warmongering.”

What might otherwise seem like a good thing – bad guys fighting bad guys – may in fact pose an increased threat to the West.

Cloud-Based Email Threats Surge 50% in 2021

There was a 50% year-on-year surge in cloud-based email threats in 2021, but a drop in ransomware and business email compromise (BEC) detections as attacks became more targeted, according to Trend Micro.

The security vendor’s 2021 roundup report, Navigating New Frontiers, was compiled from data collected by customer-installed products and cloud-based threat intelligence.

It revealed that Trend Micro blocked 25.7 million email threats targeting Google Workspace and Microsoft 365 users last year, versus 16.7 million in 2020.

The number of phishing attempts almost doubled during the period, as threat actors continued to target home workers. Of these, 38% were focused on stealing credentials, the report claimed.

https://www.infosecurity-magazine.com/news/cloudbased-email-threats-surge-2021/

Millions of New Mobile Malware Strains Blitzed Enterprise in 2021

Researchers uncovered more than two million new mobile malware samples in the wild last year, Zimperium said in a new report.

Those threats spanned some 10 million mobile devices in at least 214 countries, the Dallas, Texas-based solution provider said in its newly released 2022 Global Mobile Threat Report. Indeed, mobile malware proved in 2021 to be the most prevalent security threat to enterprises, encountered by nearly 25 percent mobile endpoints among Zimperium’s customers worldwide. The 2.3 million new mobile strains Zimperium’s researchers located amount to nearly 36,000 new strains of malware weekly and roughly 5,000 each day.

UK Criminal Defence Lawyer Hadn't Patched When Ransomware Hit

Criminal defence law firm Tuckers Solicitors is facing a fine from the UK's data watchdog for failing to properly secure data that included information on case proceedings which was scooped up in a ransomware attack in 2020.

The London-based business was handed a £98,000 penalty notice by the Information Commissioner's Office under Article 83 of the EU's General Data Protection Regulation 2018.

The breach was first noted by Tuckers on August 23 2020 when part of its IT system became unavailable. On closer inspection, resident techies found a note from the attackers confirming they had compromised part of the infrastructure. The Microsoft Exchange server was out of action and two days' worth of emails were lost, as detailed by the company blog at the time.

https://www.theregister.com/2022/03/15/brit_solicitor_fined_for_failing/

Russian Ransomware Gang Retool Custom Hacking Tools of Other APT Groups

A Russian-speaking ransomware outfit likely targeted an unnamed entity in the gambling and gaming sector in Europe and Central America by repurposing custom tools developed by other APT groups like Iran's MuddyWater, new research has found.

The unusual attack chain involved the abuse of stolen credentials to gain unauthorized access to the victim network, ultimately leading to the deployment of Cobalt Strike payloads on compromised assets, said Felipe Duarte and Ido Naor, researchers at Israeli incident response firm Security Joes, in a report published last week.

Although the infection was contained at this stage, the researchers characterized the compromise as a case of a suspected ransomware attack.

The intrusion is said to have taken place in February 2022, with the attackers making use of post-exploitation tools such as ADFind, NetScan, SoftPerfect, and LaZagne. Also employed is an AccountRestore executable to brute-force administrator credentials and a forked version of a reverse tunneling tool called Ligolo.

The Massive Impact of Vulnerabilities in Critical Infrastructure

Recent cyber events have shown how extremely vulnerable critical infrastructure is. What are the biggest security concerns?

In any world conflict, one of the primary threats posed is cyber actors disabling or destroying the core infrastructure of the adversary. Based on the global reaction to the current world conflict, countries fear reprisals. The worry is that there will be collateral damage to the critical infrastructure of other countries not directly involved in the current conflict.

Today, services such as healthcare systems, power grids, transportation and other critical industries are increasingly integrating their operational technology with traditional IT systems in order to modernize their infrastructure, and this has opened up a new wave of cyber attacks. Though businesses are ramping up their security initiatives and investments to defend and protect, their efforts have largely been siloed, reactive, and lack business context. Lack of visibility of risk across the estate is a huge problem for this sector.

Black Arrow Cyber Threat Briefing 11 March 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

Sharp Rise in SMB Cyber Attacks by Russia and China

SaaS Alerts, a cloud security company, unveiled the findings of its latest report which analysed approximately 136 million security events across 2,100 small and medium businesses (SMBs) globally and identified cyber trends negatively impacting businesses.

The findings of the report take into account security events occurring across more than 120,000 user accounts during the period of January 1st to December 31st, 2021 and shows that the vast majority of attacks on top SaaS platforms such as Microsoft 365, Google Workspace, Slack and Dropbox are originating from Russia and China. The data set is statistically significant and enables solution providers managing a portfolio of SaaS applications with pertinent data and trends to support defensive IT security re-alignments as required.

We're Seeing An 800% Increase in Cyber Attacks, Says One Managed Service Provider

Revenge and inflation are believed to be key drivers behind an 800 percent increase in cyber attacks seen by a single managed services provider since the days before the onset of Russia's invasion of Ukraine last month.

The attacks are coming not only from groups inside of Russia but also from elsewhere within the region as well from Russia allies like North Korea and Iran, historically sources of global cyber-threats.

The MSP serves about 2,400 companies around the world, most of them small businesses and midsize enterprises and most in North America. The MSP said it has seen the spike in cyber attacks throughout its customer base.

The sharp rise has been attributed to pro-Russian cyber criminal groups linked to nation states lashing out at countries – first Ukraine and then Western countries – angry at the sanctions being levelled against Russia. At the same time, the sharp inflation that is spreading around the world is also hitting hackers, who need to make money to keep up with rising costs.

Internet Warfare: How the Russians Could Paralyse Britain

The collapse of critical national infrastructure is a science fiction staple. Fifty years ago, actively switching off a country’s water and power networks would have required huge physical damage to power stations and the sources of those services. Today, however, many of the tools we use every day are connected to the internet.

All of those things now have remote access — and therefore, all of them could be vulnerable.

Ukraine has been blitzed by cyber attacks since the annexation of Crimea in 2014 and they have increased in the lead-up to the invasion. As Russia marched into Ukraine, British officials were concerned about “spillover” from any cyber offensives targeted thousands of miles away.

In today’s interconnected digital world, the reality is that distance from the conflict zone makes no difference.

As the West fears a cyber-reprisal, what would a successful attack look like in Britain — and how likely is a complete “network failure”?

Just 3% Of Employees Cause 92% Of Malware Events

A small group of employees is typically responsible for most of the digital risk in an organisation, according to new research.

The report, from cybersecurity company Elevate Security and cyber security research organisation Cyentia, also found that those putting their companies at risk from phishing, malware, and insecure browsing are often repeat offenders.

The research found that 4% of employees clicked 80% of phishing links, and 3% were responsible for 92% of malware events.

Four in five employees have never clicked on a phishing email, according to the research. In fact, it asserts that half of them never see one, highlighting the need to focus anti-phishing efforts on at-risk workers.

The malware that phishing and other attack vectors deliver also affects a small group of employees. The research found that 96% of users have never suffered from a malware event. Most malware events revolve around the 3% of users who suffered from two malware events or more, reinforcing the notion that security awareness messages just aren't getting through to some.

70% Of Breached Passwords Are Still in Use

A new report examines trends related to exposed data. Researchers identified 1.7 billion exposed credentials, a 15% increase from 2020, and 13.8 billion recaptured Personally Identifiable Information (PII) records obtained from breaches in 2021.

Through its analysis of this data, it was found that despite increasingly sophisticated and targeted cyber attacks, consumers continue to engage in poor cyber practices regarding passwords, including the use of similar passwords for multiple accounts, weak or common passwords and passwords containing easy-to-guess words or phrases connected to pop culture.

https://www.helpnetsecurity.com/2022/03/08/exposed-data-trends/

Organisations Taking Nearly Two Months to Remediate Critical Risk Vulnerabilities

Edgescan announces the findings of a report which offers a comprehensive view of the state of vulnerability management globally. This year’s report takes a more granular look at the trends by industry, and provides details on which of the known, patchable vulnerabilities are currently being exploited by threat actors.

The report reveals that organisations are still taking nearly two months to remediate critical risk vulnerabilities, with the average mean time to remediate (MTTR) across the full stack set at 60 days.

High rates of “known” (i.e. patchable) vulnerabilities which have working exploits in the wild, used by known nation state and cybercriminal groups are not uncommon.

Crucially, 57% of all observed vulnerabilities are more than two years old, with as many as 17% being more than five years old. These are all vulnerabilities that have working exploits in the wild, used by known nation state and cybercriminal groups. Edgescan also observed a concerning 1.5% of known, unpatched vulnerabilities that are over 20 years old, dating back to 1999.

Android Malware Escobar Steals Your Google Authenticator MFA Codes

The Aberebot Android banking trojan has returned under the name 'Escobar' with new features, including stealing Google Authenticator multi-factor authentication codes.

The new features in the latest Aberebot version also include taking control of the infected Android devices using VNC, recording audio, and taking photos, while also expanding the set of targeted apps for credential theft.

The main goal of the trojan is to steal enough information to allow the threat actors to take over victims' bank accounts, siphon available balances, and perform unauthorised transactions.

Like most banking trojans, Escobar displays overlay login forms to hijack user interactions with e-banking apps and websites and steal credentials from victims.

The malware also packs several other features that make it potent against any Android version, even if the overlay injections are blocked in some manner.

The authors have expanded the set of targeted banks and financial institutions to a whopping 190 entities from 18 countries in the latest version.

https://www.bleepingcomputer.com/news/security/android-malware-escobar-steals-your-google-authenticator-mfa-codes/

Smartphone Malware Is on The Rise - Here's How to Stay Safe

The volume of malware attacks targeting mobile devices has skyrocketed so far this year, cyber security researchers are saying.

A new report from security company Proofpoint claims that the number of detected mobile malware attacks has spiked 500% in the first few months of 2022, with peaks at the beginning and end of February.

Much of this malware aims to steal usernames and passwords from mobile banking applications, Proofpoint says. But some strains are even more sinister, recording audio and video from infected devices, tracking the victim's location, or exfiltrating and deleting data.

Russia May Use Ransomware Payouts to Avoid Sanctions’ Financial Harm

FinCEN warns financial institutions to be wary of unusual cryptocurrency payments or illegal transactions Russia may use to ease financial hurt from Ukraine-linked sanctions.

Russia may ramp up ransomware attacks against the United States as a way to ease the financial hurt it’s under due to sanctions, U.S. federal authorities are warning. Those sanctions have been levied against the nation and Vladimir Putin’s government due to its invasion of Ukraine.

The Financial Crimes Enforcement Network (FinCEN) issued a FinCEN Alert (PDF) on Wednesday advising all financial institutions to remain vigilant against potential efforts to evade the expansive sanctions and other U.S.-imposed restrictions related to the current conflict. One way this may be done is to move cryptocurrency funds through ransomware payments collected after Russian state-sponsored actors carry out cyberattacks.

“In the face of mounting economic pressure on Russia, it is vitally important for financial institutions to be vigilant about potential Russian sanctions evasion, including by both state actors and oligarchs,” said FinCEN Acting Director Him Das in a press statement.

How An 8-Character Password Could Be Cracked in Less Than an Hour

Security experts keep advising us to create strong and complex passwords to protect our online accounts and data from savvy cybercriminals. And “complex” typically means using lowercase and uppercase characters, numbers and even special symbols. But complexity by itself can still open your password to cracking if it doesn’t contain enough characters, according to research by security firm Hive Systems.

As described in a recent report, Hive found that an 8-character complex password could be cracked in just 39 minutes if the attacker were to take advantage of the latest graphics processing technology. A seven-character complex password could be cracked in 31 seconds, while one with six or fewer characters could be cracked instantly. Shorter passwords with only one or two character types, such as only numbers or lowercase letters, or only numbers and letters, would take just minutes to crack.

Cyber Insurance and Business Risk: How the Relationship Is Changing Reinsurance & Policy Guidance

Cyber insurance is a significant industry and growing fast — according to GlobalData, it was worth $7 billion in gross written premiums in 2020. The cyber-insurance market is expected to reach $20.6 billion by 2025. Over the past few years, the cyber-insurance market was competitive, so premiums were low and policies were comprehensive. Over the past year, that has changed — the volume of claims has gone up and led to more payouts, which affected the insurance companies' profitability.

The recent Log4j issue will affect how insurance and reinsurance companies write their policies in future. Already, we're seeing discussions about Log4j-related issues being excluded from reinsurance policies in 2022, as many policies came up for renewal on Dec. 31, 2021. This will affect the policies that insurance companies can offer to their customers.

What does this mean for IT security teams? For practitioners, it will make their work more important than before, as preventing possible issues would be more valuable to the business. Carrying out standard security practices like asset inventory and vulnerability management will be needed, while examining software bills of materials for those same issues will help on the software supply chain security side. These practices will also need to be highly automated, as business must be able to gain accurate insights within hours, not months, to deal with future threats while reducing the cost impact.

For those responsible for wider business risk, these developments around cyber insurance will present a more significant problem. Cyber-insurance policies will still be available — and necessary where needed — but the policies themselves will cover less ground. While the past few years had pretty wide-ranging policies that would pay out on a range of issues, future policies will deliver less coverage.

Security Teams Prep Too Slowly for Cyber Attacks

Attackers typically take days or weeks to exploit new vulnerabilities, but defenders are slow to learn about critical issues and take action, requiring 96 days on average to learn to identify and block current cyber threats, according to a new report analysing training and crisis scenarios.

The report, Cyber Workforce Benchmark 2022, found that cybersecurity professionals are much more likely to focus on vulnerabilities that have garnered media attention, such as Log4j, than more understated issues, and that different industries develop their security capabilities at widely different rates. Security professionals in some of the most crucial industries, such as transport and critical infrastructure, are twice as slow to learn skills compare to their colleagues in the leisure, entertainment, and retail sectors.

The amount of time it takes for security professionals to get up to speed on new threats matters. CISA says that patches should be applied within 15 days, sooner than that if the vulnerability is being exploited, says Kevin Breen, director of cyber threat research at Immersive Labs.

Top Cyber Stories of the Last Week

Cyber Criminals Exploit Invasion of Ukraine

Cyber criminals are exploiting Russia’s ongoing invasion of Ukraine to commit digital fraud.

In a blog, researchers at Bitdefender Labs said they had witnessed “waves of fraudulent and malicious emails,” some of which were engineered to exploit the charitable intentions of global citizens towards the people of Ukraine.

Since March 1, researchers have been tracking two specific phishing campaigns designed to infect victims with Agent Tesla and Remcos remote access Trojans.

Agent Tesla is a malware-as-a-service (MaaS) Remote Access Trojan (RAT) and data stealer that can be used to exfiltrate sensitive information, including credentials, keystrokes and clipboard data from victims.

Remcos RAT is typically deployed via malicious documents or archives to give the attacker full control over their victims’ systems. Once inside, attackers can capture keystrokes, screenshots, credentials and other sensitive system data and exfiltrate it.

UK Data Watchdog Urges Vigilance Amid Heightened Cyber Threat

The UK’s Information Commissioner’s Office (ICO) reports a ‘steady and significant’ increase in cyber-attacks against UK firms over the past two years.

Employees should report any suspicious emails rather than delete them and firms must step up their vigilance against cyber-attacks in the face of a heightened threat from Russian hackers, the UK’s data watchdog has said.

John Edwards, the Information Commissioner, said a new era of security had begun where instead of blacking out windows, people needed to maintain vigilance over their inboxes.

Experts including the UK’s cyber security agency have said Russian hackers could target Britain, and the imposition of sanctions by London on Moscow has increased those fears.

Asked about the potential for a Russia-Ukraine cyber conflict spreading to the UK, Edwards said: “We have picked up on that heightened threat environment and we think it’s really important to take the opportunity to remind businesses of the importance of security over the data that they hold. This is a different era from blacking out the windows and keeping the lights off. The threats are going to come in through your inbox.”

Phishing - Still a Problem, Despite All The Work

Phishing is a threat that most people know about. Emails designed to trick you into clicking a malicious link or divulge passwords and other credentials have become an everyday occurrence. Despite this familiarity, and the multitude of tools and techniques which purport to stop it, phishing remains the number one initial attack vector affecting organisations and individuals.

Unfortunately, there is no silver bullet. Phishing can only be dealt with using multiple complementary measures. This fact leads to some questions: Which measures are most (cost) effective? How should they be implemented? Can they be automated?

https://www.ncsc.gov.uk/blog-post/phishing-still-a-problem-despite-the-work

Phishing Attacks Hit All-Time High in December 2021

The Anti-Phishing Working Group international consortium (APWG) saw 316,747 phishing attacks in December 2021 — the highest monthly total observed since it began its reporting program in 2004. Overall, the number of phishing attacks has tripled from early 2020.

In the fourth quarter of 2021, the financial sector, which includes banks, became the most frequently attacked cohort, accounting for 23.2 percent of all phishing. Attacks against webmail and software-as-a-service (SaaS) providers remained prevalent as well. Phishing against cryptocurrency targets — such as cryptocurrency exchanges and wallet providers — inched up to represent 6.5 percent of attacks.

Overall, the number of brands that were attacked in 4Q descended from a record 715 in September 2021, cresting at 682 in November for the Q4 period.

The solution provider Abnormal Security observed 4,200 companies, organisations, and government institutions falling victim to ransomware in Q4 2021, some 36 percent higher than in Q3 2021 and the highest number the company has witnessed over the past two years.

“The overall distribution of ransomware victims indicates that ransomware attacks are industry-agnostic,” said Crane Hassold, Director of Threat Intelligence at Abnormal Security.

https://www.helpnetsecurity.com/2022/03/03/phishing-attacks-december-2021/

Ransomware Infections Top List of The Most Common Results of Phishing Attacks

A report from insider threat management software company Egress found some startling conclusions when it spoke to IT leadership: Despite the pervasive and very serious threat of ransomware, very few boards of directors consider it a top priority.

Eighty-four percent of organisations reported falling victim to a phishing attack last year, Egress said, and of those 59% were infected with ransomware as a result. If you add in the 14% of businesses that said they weren’t hit with a phishing attack, and you still end up at around 50% of all organisations having been hit with ransomware in 2021.

Egress said that its data shows there has been a 15% increase in successful phishing attacks over the past 12 months, with the bulk of the attacks utilising malicious links and attachments. Those methods aren’t new, but a 15% increase in successful attacks means that something isn’t working.

https://www.techrepublic.com/article/ransomware-infections-top-list-of-the-most-common-results-of-phishing-attacks/

Social Media Phishing Attacks Are at An All Time High

Phishing campaigns continue to focus on social media, ramping up efforts to target users for the third consecutive year as the medium becomes increasingly used worldwide for communication, news, and entertainment.

The targeting of social media is the highlighted finding in the 2021 Phishing report by cybersecurity firm Vade, who analysed phishing attack patterns that unfolded throughout 2021.

As part of their report, Vade analysed 184,977 phishing pages to create stats based on a billion corporate and consumer mailboxes that the cyber security firm protects.

Vade also recorded a rise in the sophistication of phishing attacks, especially those targeting Microsoft 365 credentials, an evolution in the tech support scams, and the inevitable dominance of COVID-19 and item shipping lures.

https://www.bleepingcomputer.com/news/security/social-media-phishing-attacks-are-at-an-all-time-high/

Insurance Giant AON Hit by a Cyber Attack

Professional services and insurance giant AON has suffered a cyberattack that impacted a "limited" number of systems.

AON is a multinational professional services firm offering a wide array of solutions, including business insurance, reinsurance, cyber security consulting, risk solutions, healthcare insurance, and wealth management products.

AON generated $12.2 billion of revenue in 2021 and has approximately 50,000 employees spread throughout 120 countries.

In a filing with the US SEC, AON has disclosed that they suffered a cyberattack on February 25th, 2022.

AON has not provided any details of the attack other than that it occurred and affected a limited number of systems.

The company stated that although in the early stages of assessing the incident, based on the information currently known, the company did not expect the incident to have a material impact on its business, operations or financial condition.

In addition to being an insurance broker, AON is also a leading reinsurance company, meaning that they insure the insurance companies.

How Prepared Are Organisations to Face Email-Based Ransomware Attacks?

Proofpoint released a report which provides an in-depth look at user phishing awareness, vulnerability, and resilience. The report reveals that attackers were more active in 2021 than 2020, with findings uncovering that 78% of organisations saw email-based ransomware attacks in 2021, while 77% faced business email compromise attacks (BEC) (18% YoY increase of BEC attacks from 2020), reflecting cyber criminals’ continued focus on compromising people, as opposed to gaining access to systems through technical vulnerabilities

This year’s report examines responses from commissioned surveys of 600 information and IT security professionals and 3,500 workers in the U.S., Australia, France, Germany, Japan, Spain, and the UK. The report also analyses data from nearly 100 million simulated phishing attacks sent by customers to their employees over a one-year period, along with more than 15 million emails reported via the user-activated PhishAlarm reporting button.

Attacks in 2021 also had a much wider impact than in 2020, with 83% of survey respondents revealing their organisation experienced at least one successful email-based phishing attack, up from 57% in 2020. In line with this, 68% of organisations said they dealt with at least one ransomware infection stemming from a direct email payload, second-stage malware delivery, or other exploit. The year-over-year increase remains steady but representative of the challenges organisations faced as ransomware attacks surged in 2021.

https://www.helpnetsecurity.com/2022/02/28/email-based-ransomware-attacks/

The Most Impersonated Brands in Phishing Attacks

Vade announced its annual ranking of the top 20 most impersonated brands in phishing. Facebook, which was in the second spot in 2020, rose to the top spot for 2021, representing 14% of phishing pages, followed by Microsoft, with 13%.

The report analysed 184,977 phishing pages linked from unique phishing emails between January 1, 2021 and December 31, 2021.

Key findings:

·         Financial services is the most impersonated industry

·         Microsoft is the most impersonated cloud brand and the top corporate brand

·         Facebook dominates social media phishing

·         35% of all phishing pages impersonated financial services brands

·         Mondays and Tuesdays are the top days for phishing

·         78% of phishing attacks occur on weekdays

·         Monday and Thursday are the top days for Facebook phishing

·         Thursday and Friday are the top days for Microsoft phishing

As War Escalates in Europe, It’s ‘Shields Up’ For The Cyber Security Industry

In unprecedented times, even government bureaucracy moves quickly. As a result of the heightened likelihood of cyberthreat from Russian malactor groups, the US Cybersecurity and Infrastructure Security Agency (CISA) — part of the Department of Homeland Security — issued an unprecedented warning recommending that “all organisations — regardless of size — adopt a heightened posture when it comes to cyber security and protecting their most critical assets.”

The blanket warning is for all industries to take notice. Indeed, it’s a juxtaposition of sorts to think the cyber security industry is vulnerable to cyber attack, but for many nation state groups, this is their first port of call.

Inspired by the spike in attacks on cyber security agencies globally, a report from Reposify assessed the state of the cyber security industry’s external attack surface (EAS). It coincides with CISA’s warning, and highlights critical areas of concern for the sector and how they mirror trends amongst pharmaceutical and financial companies, providing vital insight into where organisations can focus their efforts, and reinforce the digital perimeter.

2022 May Be The Year Cyber Crime Returns Its Focus to Consumers

Threat analysts expect 2022 to be the tipping point for a shift in the focus of hackers from large companies back to consumers.

This prediction is the result of several factors that make consumers a lot more lucrative to threat actors today than in previous years.

ReasonLabs has compiled a detailed report on the status of consumer-level cyber security and what trends are most likely to emerge this year.

https://www.bleepingcomputer.com/news/security/2022-may-be-the-year-cybercrime-returns-its-focus-to-consumers/

Kaspersky Neutral Stance in Doubt As It Shields Kremlin

Kaspersky Lab is protecting the resources of the Russian Ministry of Defence and other high-value domains that are instrumental to the Russian propaganda machine – Russia Today, TASS news agency, Gazprom bank.

The company insists that they ‘never provide any law enforcement or government organisation with access to user data or the company's infrastructure.”

Eugene Kaspersky's refusal to condemn the Kremlin for its invasion of Ukraine set the cyber security community on fire. His company has tried to shake ties to the Russian government for years but hasn't succeeded quite yet. And recent events, it seems, only made things worse.

"We welcome the start of negotiations to resolve the current situation in Ukraine and hope that they will lead to a cessation of hostilities and a compromise. We believe that peaceful dialogue is the only possible instrument for resolving conflicts. War isn't good for anyone," Eugene Kaspersky tweeted when Russian and Ukrainian delegations met for peace talks near Ukraine's border with Belarus.

Black Arrow Cyber Threat Briefing 25 February 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

Britain Warns of Cyber Attacks as Russia-Ukraine Crisis Escalates

Britain warned of potential cyber attacks with "international consequences" this week after Russian President Vladimir Puitin ordered troops to two breakaway regions in eastern Ukraine.

Britain's National Cyber Security Centre (NCSC), a part of the GCHQ eavesdropping intelligence agency, called on British organisations to "bolster their online defences" following the developments.

"While the NCSC is not aware of any current specific threats to UK organisations in relation to events in and around Ukraine, there has been an historical pattern of cyber attacks on Ukraine with international consequences," it said in a statement.

Last week, Ukranian banking and government websites were briefly knocked offline by a spate of distributed denial of service (DDoS) attacks which the United States and Britain said were carried out by Russian military hackers.

Ransomware Extortion Doesn't Stop After Paying The Ransom

A global survey that looked into the experience of ransomware victims highlights the lack of trustworthiness of ransomware actors, as in most cases of paying the ransom, the extortion simply continues.

This is not a surprising or new discovery, but when seeing it reflected in actual statistics, one can appreciate the scale of the problem in full.

The survey was conducted by cyber security specialist Venafi, and the most important findings that emerge from the respondents are the following:

• 18% of victims who paid the ransom still had their data exposed on the dark web.

• 8% refused to pay the ransom, and the attackers tried to extort their customers.

• 35% of victims paid the ransom but were still unable to retrieve their data.

As for the ransomware actor extortion tactics, these are summarized as follows:

• 83% of all successful ransomware attacks featured double and triple extortion.

• 38% of ransomware attacks threatened to use stolen data to extort customers.

• 35% of ransomware attacks threatened to expose stolen data on the dark web.

• 32% of attacks threatened to directly inform the victim's customers of the data breach incident.

Ukraine Calls For Volunteer Hackers To Protect Its Critical Infrastructure And Spy On Russian Forces

The government of Ukraine is calling on the hacking community to volunteer its expertise and capabilities, following the invasion of the country by Russian forces.

Reuters reports that Yegor Aushev, the CEO of Kyiv-based Cyber Unit Technologies which has worked with Ukraine's government on the defence of critical infrastructure, claims to have been asked to post a digital call-to-arms after being asked by "a senior Defence Ministry official."

The message, which was posted on hacking forums by Aushev on Thursday, begins "Ukrainian cybercommunity! It’s time to get involved in the cyber defense of our country," and calls for cybersecurity experts and hackers to apply as a volunteer via a Google Docs link.  The page volunteers are directed to asks applicants to list their specialities, such as if they have developed malware, and professional references.

According to Aushev, volunteers will be divided into two groups - tasked with offensive and defensive cyber operations.

Study: UK Firms Most Likely To Pay Ransomware Hackers

Some 82% of British firms which have been victims of ransomware attacks paid the hackers in order to get back their data, a new report suggests.

The global average was 58%, making the UK the most likely country to pay cyber-criminals.

Security firm Proofpoint's research also found that more than three-quarters of UK businesses were affected by ransomware in 2021.

Phishing attacks remain the key way criminals access networks, it found.

Phishing happens when someone in a firm is lured into clicking on a link in an email that contains malware, which in turn can help cyber-criminals access company networks.

Conti Ransomware Group Announces Support of Russia, Threatens Retaliatory Attacks

An infamous ransomware group with potential ties to Russian intelligence and known for attacking health care providers and hundreds of other targets posted a warning Friday saying it was “officially announcing a full support of Russian government.”

The gang said that it would use “all possible resources to strike back at the critical infrastructures” of any entity that organises a cyberattack “or any war activities against Russia.” The message appeared Friday on the dark-web site used by ransomware group Conti to post threats and its victims’ data. Security researchers believe the gang to be Russia-based.

Conti ransomware was part of more than 400 attacks against mostly U.S. targets between spring 2020 and spring 2021, the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) and the FBI reported in September.

91% of UK Organisations Compromised by an Email Phishing Attack in 2021

More than nine in 10 (91%) UK organizations were successfully compromised by an email phishing attack last year, according to Proofpoint’s 2022 State of the Phish report.

The study observed a significant rise in email-based attacks globally in 2021 compared to 2020. Over three-quarters (78%) of organizations were targeted by email-based ransomware attacks last year and 77% faced business email compromise (BEC) attacks, the latter an 18% year-on-year increase from 2020.

The survey of 600 information and IT security professionals and 3500 workers in the US, Australia, France, Germany, Japan, Spain and the UK also found that attacks in 2021 were more likely to be successful than in 2020. More than four in five (83%) respondents said their organization experienced at least one successful email-based phishing attack last year, up from 57% in 2020. In addition, 68% of organizations admitted they had to deal with at least one ransomware infection stemming from a direct email payload, second-stage malware delivery or other exploit.

Worryingly, 60% of organizations infected with ransomware admitted to paying a ransom, with around a third (32%) paying additional sums to regain access to data and systems.

Almost 100,000 New Mobile Banking Trojan Strains Detected In 2021

Researchers have found almost 100,000 new variants of mobile banking Trojans in just a year.

As our digital lives have begun to centre more on handsets rather than just desktop PCs, many malware developers have shifted part of their focus to the creation of mobile threats.

Many of the traditional infection routes are still workable -- including phishing and the download and execution of suspicious software -- but cyber attackers are also known to infiltrate official app stores, including Google Play, to lure handset owners into downloading software that appears to be trustworthy.

This technique is often associated with the distribution of Remote Access Trojans (RATs). While Google maintains security barriers to stop malicious apps from being hosted in its store, there are methods to circumvent these controls quietly.

Anonymous Collective Has Hacked The Russian Defence Ministry And Leaked The Data Of Its Employees In Response To The Ukraine Invasion

A few hours after the Anonymous collective has called to action against Russia following the illegitimate invasion of Ukraine its members have taken down the website of the Russian propaganda station RT News and news of the day is the attack against the servers of the Russian Defense Ministry.

“Anonymous, a group of hacktivists, successfully hacked and leaked the database of the website of the Ministry of Defense of Russia.” reported the Pravda agency.

The website of the Kremlin (Kremlin.ru) is also unreachable, but it is unclear if it is the result of the Anonymous attack or if the government has taken offline it to prevent disruptive attacks.

The Russian Government’s portal, and the websites of other ministries are running very slow.

The collective is also threatening the Russian Federation and private organizations of attacks, it is a retaliation against Putin’s tyranny.

Anonymous pointed out that it is not targeting Russian citizens, but only their government.

“We want the Russian people to understand that we know it’s hard for them to speak out against their dictator for fear of reprisals.”

Email Remains Go-To Method for Cyber Attacks, Phishing Research Report Finds

If you don’t know what it is, if you can’t identify it and if you can’t make sure you don’t topple into its traps, then you can’t fight it, suggests a new report by security provider Proofpoint in its eighth annual State of the Phish report.

The “it” is email-based malware attacks, the kingpin of all hacking methods, that victims often fall for out of a lack of awareness, inadequate training or risky behaviours, such as using a company mobile device for home use.

Proofpoint’s report takes an in-depth look at user phishing awareness, vulnerability and resilience and comes away with some startling numbers: More than three-quarters of organizations associated with the 4,100 IT security professionals and staffers in the worldwide study were hit by email-based ransomware attacks in 2021 and an equal number were victimized by business email compromise attacks, an 18 percent spike from 2020.

What explains the year-over-year climb? Answer: Cyber criminals continue to focus on compromising people, not necessarily systems, Proofpoint said. Email remains cyber criminals’ go-to attack strategy, said Alan Lefort, Proofpoint security awareness training senior vice president and general manager. “Infosec and IT survey participants experienced an increase in targeted attacks in 2021 compared to 2020, yet our analysis showed the recognition of key security terminology such as phishing, malware, smishing (text-based ruse), and vishing (telephone trickery) dropped significantly,” said Lefort. “The awareness gaps and lax security behaviors demonstrated by workers creates substantial risk for organizations and their bottom line.”

The Future of Cyber Insurance

In 2016, just 26% of insurance clients had cyber coverage. That number rose to 47% in 2020, according to a US Government Accountability Office (GAO) report. But the demand for cyber coverage isn't the only thing soaring.

At the end of 2020, insurance prices jumped anywhere from 10% to 30%. In the third quarter of 2021, the average cost of cyber insurance premiums climbed a record 27.6%.

If the rates continue to rise, companies might decide it's not worth the cost. That is, if insurers continue to cover their industry.

Businesses Are at Significant Risk of Cyber Security Breaches Due to Immature Security Hygiene and Posture Management Practices

Enterprise Strategy Group (ESG), a leading IT analyst, research, and strategy firm, and a division of TechTarget, Inc., today announced new research into security hygiene and posture management – a foundational part of a strong security program. The study reveals that many aspects of cyber security are managed independently and with antiquated tools, leaving organisations with limited visibility and weak defenses against an ever-evolving threat landscape. Since strong cybersecurity starts with the basics, like knowing about all IT assets deployed, this situation makes organisations vulnerable to advanced threats among strategic, yet often hurried, cloud and digital transformation initiatives.

The new report, Security Hygiene and Posture Management, summarizes a survey of 398 IT and cyber security professionals responsible for evaluating, purchasing, and utilizing products and services for security hygiene and posture management, including vulnerability management, asset management, attack surface management, and security testing tools. The data reveals that organisations must aim to further assess security posture management processes, examine vendor risk management requirements, and test security tool and processes more frequently.

Microsoft Teams Is The New Frontier For Phishing Attacks

Even with email-based phishing attacks proving to be more successful than ever, cyberattackers are ramping up their efforts to target employees on additional platforms, such as Microsoft Teams and Slack.

One advantage is that in those applications, most employees still assume that they’re actually talking to their boss or coworker when they receive a message.

“The scary part is that we trust these programs implicitly — unlike our email inboxes, where we’ve learned to be suspicious of messages where we don’t recognize the sender’s address,” said anti-fraud technology firm Outseer.

Notably, traditional phishing has seen no slowdown: Proofpoint reported that 83% of organizations experienced a successful email-based phishing attack in 2021 — a massive jump from 57% in 2020. And outside of email, SMS attacks (smishing) and voice-based attacks (vishing) both grew in 2021, as well, according to the email security vendor.

However, it appears that attackers now view widely used collaboration platforms, such as Microsoft Teams and Slack, as another growing opportunity for targeting workers, security researchers and executives say. For some threat actors, it’s also a chance to leverage the additional capabilities of collaboration apps as part of the trickery.

Black Arrow Cyber Alert – Ukraine Crisis Impact, Escalating Russian Hostilities

Black Arrow Cyber Alert – Ukraine Crisis Impact , Escalating Russian Hostilities

Executive Summary

As the crisis in Ukraine continues to escalate, Black Arrow are advising all parties to remain vigilant to an increasingly likely flashpoint that will include cyber attacks. While the conflict may take place far away from the Channel Islands, UK and wider world, these borders are negligible, if they exist at all, in the digital space.

We recommend you provide your staff with additional awareness to the potential for attack and damage, which may present itself in several ways and not necessarily be targeted. These might be traditional email-based attacks, though they may also involve delivery mechanisms such as infected documents, malicious websites or direct attacks on infrastructure. In many cases, staff may be accustomed to receiving emails with links and documents from trusted third parties, however in the current climate these should be treated with caution in case the correspondence or the sender’s account has been compromised or spoofed.

Due to the involvement of national governments and the funding this provides, there is a strong likelihood of zero-day attacks being used that have been developed for wartime scenarios. Criminal enterprises are also likely to take advantage of any chaos, as they have during the Covid-19 Pandemic. These may include emails with an official appearance or warning, Smishing campaigns or other methods that leverage urgency and fear. Staff should be encouraged to report any suspicious activity, no matter how small.

We also recommend that you confirm, in detail, the monitoring that is in place through your internal IT function or outsourced IT provider, and how they would identify and alert you to an attempted or ongoing incident. This should be part of your incident response plan, which is rehearsed regularly.
