Black Arrow Cyber Advisory – Trend Micro Disclose Samba (SMB) Remote Code Execution Bug

Black Arrow Cyber Advisory – Trend Micro Disclose Samba (SMB) Remote Code Execution Bug

Executive Summary

Trend Micro, a large player in the security product market, have disclosed a bug this month in the Samba (SMB) protocol that allows attackers to remotely execute code on affected systems. Samba operates in almost every environment, most often found on network storage devices like QNAP, Synology or Windows file shares. The bug received a 9.9 on the CVSS scale, primarily due to the remote root or administrator capabilities of an attacker if exploited.

What’s the risk to me or my business?

Samba is an extremely common protocol and is often the default solution when configuring a file share, meaning the likelihood it exists in your environment is high. While the bug is not noted to be widely exploited at this time, 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 by Samba to address the issue. The bug affects all instances of Samba before version 4.13.17, and it is advised that network administrators patch as soon as possible.

Technical Summary

A new bug disclosed by Trend Micro allows attackers to remotely exploit Samba installations prior to version 4.13.17. The exploit can be conducted without authentication and leverages the parsing of EA metadata in the Samba server daemon, smbd. Using an out-of-bounds heap manipulation, an attacker can execute code in the context of root, thus granting low level access to the system.

Top Cyber Stories of the Last Week

UK Warned To Bolster Defences Against Cyber Attacks As Russia Threatens Ukraine - BBC News

UK organisations are being urged to bolster their defences amid fears cyber attacks linked to the conflict in Ukraine could move beyond its borders.

The National Cyber Security Centre (NCSC) has issued new guidance, saying it is vital companies stay ahead of a potential threat.

The centre said it was unaware of any specific threats to UK organisations.

It follows a series of cyber attacks in Ukraine which are suspected to have involved Russia, which Moscow denies.

In December 2015, engineers in Ukrainian power stations saw cursors on their computer screens moving by themselves. They had been hacked. Hundreds of thousands of people lost power for hours.

It was the first time a power station had been taken offline, a sign that cyber intrusions were moving beyond stealing information into disrupting the infrastructure on which everyday life depends. Russia was blamed.

"It was a complex operation," says John Hultquist, an expert on Russian cyber operations at the US security firm Mandiant. "They even disrupted the telephone lines so that the engineers couldn't make calls."

Ukraine has been on the front line of a cyber conflict for years. But if Russia does invade the country soon, tanks and troops will still be at the forefront.

Cyber Attacks And Ransomware Hit A New Record In 2021, Says Report

Ransomware attacks have doubled for the past two years, says a new report—but a lot of people aren’t bothering to change their passwords.

Hackers made up for some lost time last year.

After seeing the number of data breaches decline in 2020, the Identity Theft Resource Center’s 16th Annual Data Breach Report says the number of security compromises was up more than 68% in 2021. That tops the all-time high by a shocking 23%.

All told, there were 1,862 breaches last year, says the ITRC, 356 more than in 2017, the previous busiest year on record.

“Many of the cyber attacks committed were highly sophisticated and complex, requiring aggressive defences to prevent them,” Eva Velasquez, ITRC president and CEO, said in a statement. “If those defences failed, too often we saw an inadequate level of transparency for consumers to protect themselves from identity fraud.”

Ransomware Families Becoming More Sophisticated With Newer Attack Methods

Ivanti, Cyber Security Works and Cyware announced a report which identified 32 new ransomware families in 2021, bringing the total to 157 and representing a 26% increase over the previous year.

The report also found that these ransomware groups are continuing to target unpatched vulnerabilities and weaponize zero-day vulnerabilities in record time to instigate crippling attacks. At the same time, they are broadening their attack spheres and finding newer ways to compromise organisational networks and fearlessly trigger high-impact assaults.

https://www.helpnetsecurity.com/2022/01/28/new-ransomware-families/

More Than 90% Of Enterprises Surveyed Have Been Hit By Successful Cyber Attacks

Cyber attacks can impact any organisation, big or small. But large enterprises are often more tempting targets due to the vast amount of lucrative data they hold. A new report from cyber security firm Anomali reveals an increase in successful cyber attacks and offers ideas on how organisations can better protect themselves.

Published on Thursday, the "2022 Anomali Cyber security Insights Report" is based on a survey of 800 cyber security decision makers commissioned by Anomali and conducted by Harris between September 9 and October 13 of 2021. The survey elicited responses from professionals in the US, UK, Canada and other countries who work full time in such industries as manufacturing, telecommunications and financial services.

Among the respondents, 87% said that their organisations were victims of successful cyber attacks sometime over the past three years. In this case, a successful attack is one that caused damage, disruption or a data breach. Since the pandemic started almost two years ago, 83% of those polled have experienced an increase in attempted cyber attacks, while 87% have been hit with a rise in phishing emails, many of them exploiting coronavirus-related themes.

https://www.techrepublic.com/article/more-than-90-of-enterprises-surveyed-have-been-hit-by-successful-cyberattacks/

Ransomware Gangs Increase Efforts To Enlist Insiders For Attacks

A recent survey of 100 large (over 5,000 employees) North American IT firms shows that ransomware actors are making greater effort to recruit insiders in targeted firms to aid in attacks.

The survey was conducted by Hitachi ID, which performed a similar study in November 2021. Compared to the previous survey, there has been a 17% rise in the number of employees offered money to aid in ransomware attacks against their employer.

Most specifically, 65% of the survey respondents say that they or their employees were approached between December 7, 2021, and January 4, 2022, to help hackers establish initial access.

https://www.bleepingcomputer.com/news/security/ransomware-gangs-increase-efforts-to-enlist-insiders-for-attacks/

Shipment-Delivery Scams Become the Favoured Way to Spread Malware

Attackers increasingly are spoofing the courier DHL and using socially engineered messages related to packages to trick users into downloading Trickbot and other malicious payloads.

Threat actors are increasingly using scams that spoof package couriers like DHL or the U.S. Postal Service in authentic-looking phishing emails that attempt to dupe victims into downloading credential-stealing or other malicious payloads, researchers have found.

Researchers from Avanan, a Check Point company, and Cofense have discovered recent phishing campaigns that include malicious links or attachments aimed at infecting devices with Trickbot and other dangerous malware, they reported separately on Thursday.

The campaigns separately relied on trust in widely used methods for shipping and employees’ comfort with receiving emailed documents related to shipments to try to elicit further action to compromise corporate systems, researchers said.

https://threatpost.com/shipment-delivery-scams-a-fav-way-to-spread-malware/178050/

Most Ransomware Infections Are Self-Installed

New research from managed detection and response (MDR) provider Expel found that most ransomware attacks in 2021 were self-installed.

The finding was included in the company’s inaugural annual report on cyber security trends and predictions, Great eXpeltations, published on Thursday.

Researchers found eight out of ten ransomware infections occurred after victims unwittingly opened a zipped file containing malicious code. Abuse of third-party access accounted for 3% of all ransomware incidents, and 4% were caused by exploiting a software vulnerability on the perimeter.

The report was based on the analysis of data aggregated from Expel’s security operations center (SOC) concerning incidents spanning January 1 2021 to December 31 2021.

Other key findings were that 50% of incidents were BEC (business email compromise) attempts, with SaaS apps a top target.

Staff Negligence Is Now A Major Reason For Insider Security Incidents

Insider threats cost organisations approximately $15.4 million every year, with negligence a common reason for security incidents, new research suggests.

Enterprise players today are facing cyber security challenges from every angle. Weak endpoint security, unsecured cloud systems, vulnerabilities -- whether unpatched or zero-days -- the introduction of unregulated internet of things (IoT) devices to corporate networks and remote work systems can all become conduits for a cyber attack to take place.

When it comes to the human element of security, a lack of training or cyber security awareness, mistakes, or deliberate, malicious actions also needs to be acknowledged in managing threat detection and response.

22 Cyber Security Myths Organisations Need To Stop Believing In 2022

Security teams trying to defend their organisations need to adapt quickly to new challenges. Yesterday’s buzzwords and best practices have become today’s myths.

The past few years have seen a dramatic shift in how organisations protect themselves against attackers. The hybrid working model, fast-paced digitalization, and increased number of ransomware incidents have changed the security landscape, making CISOs' jobs more complex than ever.

This convoluted environment requires a new mindset to defend, and things that might have held true in the past might no longer be useful. Can digital certificates' expiration dates still be managed in a spreadsheet? Is encryption 'magic dust'? And are humans actually the weakest link?

Security experts weigh in the 22 cyber security myths that we finally need to retire in 2022.

Android Malware Can Factory-Reset Phones After Draining Bank Accounts

A banking-fraud trojan that has been targeting Android users for three years has been updated to create even more grief. Besides draining bank accounts, the trojan can now activate a kill switch that performs a factory reset and wipes infected devices clean.

Brata was first documented in a post from security firm Kaspersky, which reported that the Android malware had been circulating since at least January 2019. The malware spread primarily through Google Play but also through third-party marketplaces, push notifications on compromised websites, sponsored links on Google, and messages delivered by WhatsApp or SMS. At the time, Brata targeted people with accounts from Brazil-based banks.

GDPR Fines Surged Sevenfold to $1.25 Billion in 2021: Study

Fines issued for GDPR non-compliance increased sevenfold from 2020 to 2021, analysis shows

In its latest annual GDPR summary, international law firm DLA Piper focuses attention in two areas: fines imposed and the evolving effect of the Schrems II ruling of 2020. Fines are increasing and Schrems II issues are becoming more complex.

Fines issued for GDPR non-compliance increased significantly (sevenfold) in 2021, from €158.5 million (approximately $180 million) in 2020 to just under €1.1 billion (approximately $1.25 billion) in 2021. The largest fines came from Luxembourg against Amazon (€746 million / $846 million), and Ireland against WhatsApp (€225 million / $255 million). Both are currently being appealed.

The WhatsApp fine is interesting. The original fine proposed by the Irish Data Protection Commission (DPC) was for €30 million to €50 million. However, other European regulators objected, and the European Data Processing Board (EDPB) adjudicated – instructing Ireland to increase the fine by 350%.

Cyber Security In 2022 – A Fresh Look At Some Very Alarming Stats

Last year Forbes wrote a couple of articles  that highlighted some of the more significant cyber statistics associated with our expanding digital ecosystem.  In retrospect, 2021 was a very trying year for cyber security in so many areas. There were high profile breaches such as Solar Winds, Colonial Pipeline and dozens of others that had major economic and security related impact.  Ransomware came on with a vengeance targeting many small and medium businesses.  

Perhaps most worrisome was how critical infrastructure and supply chains security weaknesses were targeted and exploited by adversaries at higher rates than in the past.  Since it is only January, we are just starting to learn of some of the statistics that certainly will trend in 2022.  By reviewing the topics below, we can learn what we need to fortify and bolster in terms of cyber security throughout the coming year.

Black Arrow Cyber Advisory – LockBit Ransomware Now Actively Targeting VMware ESXi Hosts

Black Arrow Cyber Advisory – LockBit Ransomware Now Actively Targeting VMware ESXi Hosts

Executive Summary

LockBit, a ransomware gang that first came to prominence in 2021, has made improvements to its Ransomware-as-a-Service (RaaS), advertising that it will now actively target VMware ESXi virtual machines. VMware ESXi is a highly popular virtualisation platform and is found in most business environments globally and allows for the consolidation of software servers and services onto a single physical machine, saving both space and costs. The new LockBit features include the ability to find all running Virtual Machines (VMs) and manipulate their power states to ensure they are encrypted successfully.

What’s the risk to me or my business?

Due to the popularity of ESXi, there is an increased risk to those running the platform. The changes demonstrate that RaaS operators are keenly aware that businesses present lucrative targets, actively implementing features that have the greatest potential for harm in an enterprise environment.

What can I do?

Ensure that your systems and services across your network remain up-to-date and current. Attackers will often use a combination of bugs, vulnerabilities and misconfigurations to breach an environment before going on to exploit other devices. For ESXi specifically, consider disabling Secure Shell (SSH) if enabled, and ensure the use of TLS (HTTPS) on any exposed web interfaces.

Black Arrow Cyber Advisory – “PwnKit” Bug Allows Root Access on the Ubiquitous Linux Operating System

Black Arrow Cyber Advisory – “PwnKit” Bug Allows Root Access on the Ubiquitous Linux Operating System

Executive Summary

Security researchers have revealed a new toolkit bug in the Linux operating system, the software that drives most of the world. Linux is found everywhere, from firewalls and network switches to cars and huge industrial machines. The tool, ‘pkexec’, was found to be vulnerable to privilege escalation, allowing an attacker to gain root or administrator privileges with ease.

What’s the risk to me or my business?

As Linux runs in almost every environment in the world, an attacker with access to the system could exploit the vulnerability to take control. The attack can become particularly potent when used in combination with other exploits on an unpatched system. Security researchers note the attack is ‘trivially exploitable’, leading to a dangerous situation if a system is indeed susceptible.

What can I do?

A patch has been issued for the bug, which should be implemented as soon as possible on any device that may be running Linux. It is recommended that systems in general be patched as often as practicable to reduce overall risk.

Technical Summary

Security researchers have disclosed a buffer overflow attack in Polkit, a tool allowing programs without special privileges to run safely with services requiring root. The bug exploits environment variables, allowing an attacker to use NULL references to craft the overflow. As a result a malicious user could, even on an account with minimal privileges, use the misalignment to introduce dangerous environment variables to elevate their session.

Black Arrow Cyber Advisory – 20,000 HP Servers Have Their Management Interface Exposed to the Internet

Black Arrow Cyber Advisory – 20,000 HP Servers Have Their Management Interface Exposed to the Internet

Executive Summary

Integrated Lights Out (iLO) is a low-level management interface on Hewlett-Packard (HP) servers, intended for out-of-band or outside-of-operating system access. The service is most used by IT staff managing the device for remote support operations, such as powering the system off, updating firmware or viewing the display via the network. Despite a recent and serious bug dubbed ‘iLOBleed’, approximately 24,000 iLO devices are still exposed to the internet and searchable with Google.

What’s the risk to me or my business?

HP servers are very common in business settings and remain the popular choice globally. Most of these servers come with iLO pre-installed, which makes them a lucrative target to attackers when vulnerable, particularly given their low-level access. In combination with vulnerabilities like ‘iLOBleed’, remotely exposing iLO to the web presents a low hanging fruit that may be too attractive to pass up.

What can I do?

Check with your IT team or MSP to ensure that you aren’t exposing anything to the web that shouldn’t be there, even beyond iLO. Misconfigurations or services such as Universal Plug and Play (UPNP) can expose devices without your knowledge, leaving you open to attack where the exposed systems are vulnerable.

The Ukraine Crisis – The Overspill from Cyber Warfare Threatens Us All

The Ukraine Crisis – The Overspill from Cyber Warfare Threatens Us All

Over the past few weeks, the global media has been alerting us all to the prospect of aggressive action by Russia in Ukraine. The US has warned of imminent acts of provocation to create a pretext to invade Ukraine, and today the UK has started to withdraw embassy staff.

Conflict is no longer restricted to the physical world. We might think we are a safe distance away from the front line, but modern warfare does not care about international borders.

Over the past few weeks, the global media has been alerting us all to the prospect of aggressive action by Russia in Ukraine. The US has warned of imminent acts of provocation to create a pretext to invade Ukraine, and today the UK has started to withdraw embassy staff.

Conflict is no longer restricted to the physical world. We might think we are a safe distance away from the front line, but modern warfare does not care about international borders.

The last time Russia took aggressive action against Ukraine, companies across the world found themselves victim of an attack that got out of control. Russia was named by several intelligence agencies as having injected the NotPetya encrypting malware through a Ukrainian tax preparation software in 2017 to target Ukrainian assets. The situation eventually spiralled to infect thousands of businesses across the world, causing serious damage.

The situation could be more serious this time. The risk of damage to companies in the Channel Islands and UK from a Russian cyber attack increases further when sides are taken, with the US, UK and other allied nations likely to take up at least some degree of involvement. The British Government for example, plans to invest £5 billion in retaliatory cyber attacks, creating their very own “Cyber Force” to target hostile states.

We need to learn from this, and we advise you to ensure you have appropriate controls in place to help protect yourself and if necessary to be able to recover if you are affected by an attack. These controls must be across people, operations and technology; it is impossible for technology alone to give the necessary protection.

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 Risks Top Worldwide Business Concerns In 2022

Cyber perils are the biggest concern for companies globally in 2022, according to the Allianz Risk Barometer. The threat of ransomware attacks, data breaches or major IT outages worries companies even more than business and supply chain disruption, natural disasters or the COVID-19 pandemic, all of which have heavily affected firms in the past year.

Cyber incidents tops the Allianz Risk Barometer for only the second time in the survey’s history (44% of responses), Business interruption drops to a close second (42%) and Natural catastrophes ranks third (25%), up from sixth in 2021. Climate change climbs to its highest-ever ranking of sixth (17%, up from ninth), while Pandemic outbreak drops to fourth (22%).

The annual survey incorporates the views of 2,650 experts in 89 countries and territories, including CEOs, risk managers, brokers and insurance experts. View the full global and country risk rankings.

Bosses Think That Security Is Taken Care Of: CISOs Aren't So Sure

The World Economic Forum warns about a significant gap in understanding between C-suites and information security staff - but it's possible to close the gap.

Organisations could find themselves at risk from cyberattacks because of a significant gap between the views of their own security experts and the boardroom.

The World Economic Forum's new report, The Global Cyber Security Outlook 2022, warns there are big discrepancies between bosses and information security personnel when it comes to the state of cyber resilience within organisations.

According to the paper, 92% of business executives surveyed agree that cyber resilience is integrated into enterprise risk management strategies – or in other words, protecting the organisation against falling victim to a cyberattack, or mitigating the incident so it doesn't result in significant disruption.

However, only 55% of security-focused executives believe that cyber resilience is integrated into risk management strategies – indicating a significant divide in attitudes to cyber security.

This gap can leave organisations vulnerable to cyberattacks, because boardrooms believe enough has been done in order to mitigate threats, while in reality there could be unconsidered vulnerabilities or extra measures put in place.

Fraud Is On the Rise, and It's Going to Get Worse

The acceleration of the digital transformation resulted in a surge of online transactions, greater adoption of digital payments, and increased fraud.

As more daily activities — work, education, shopping, and entertainment — shift online, fraud is also on the rise. A trio of recent reports paint a bleak picture, highlighting concerns that companies are experiencing increasing losses from fraud and that the situation will get worse over the coming year.

In KPMG's survey of senior risk executives, 67% say their companies have experienced external fraud in the past 12 months, and 38% expect the risk of fraud committed by external perpetrators to somewhat increase in the next year. External fraud, which includes credit card fraud and identity theft, is specifically referring to incidents perpetuated by individuals outside the company. For most of these respondents, there was a financial impact: Forty-two percent say their organisations experienced 0.5% to 1% of loss as a result of fraud and cybercrime.

Two-Fifths of Ransomware Victims Still Paying Up

Two-fifths (39%) of ransomware victims paid their extorters over the past three years, with the majority of these spending at least $100,000, according to new Anomali research.

The security vendor hired The Harris Poll to complete its Cyber Resiliency Survey – interviewing 800 security decision-makers in the US, Canada, the UK, Australia, Singapore, Hong Kong, India, New Zealand, the UAE, Mexico and Brazil.

Some 87% said their organisation had been the victim of a successful attack resulting in damage, disruption, or a breach since 2019. However, 83% said they’d experienced more attacks since the start of the pandemic.

Over half (52%) were ransomware victims, with 39% paying up. Of these, 58% gave their attackers between $100,000 and $1m, while 7% handed over more than $1m.

Less Than a Fifth of Cyber Leaders Feel Confident Their Organisation is Cyber-Resilient

Less than one-fifth (17%) of cyber leaders feel confident that their organisations are cyber-resilient, according to the World Economic Forum (WEF)’s inaugural Global Cyber Security Outlook 2022 report.

The study, written in collaboration with Accenture, revealed there is a wide perception gap between business executives and security leaders on the issue of cyber security. For example, 92% of businesses believe cyber-resilience is integrated into their enterprise risk-management strategies, compared to just 55% of cyber leaders.

This difference in attitude appears to be having worrying consequences. The WEF said that many security leaders feel that they are not consulted in security decisions, and only 68% believe cyber-resilience forms a major part of their organisation’s overall corporate risk management.

In addition, over half (59%) of all cyber leaders admitted they would find it challenging to respond to a cyber security incident due to a shortage of skills within their team.

Supply chain security was another major concern among cyber leaders, with almost nine in 10 (88%) viewing SMEs as a key threat to supply chains.

Interestingly, 59% of cyber leaders said cyber-resilience and cyber security are synonymous, with the differences not well understood.

Endpoint Malware And Ransomware Detections Hit All-Time High

Endpoint malware and ransomware detections surpassed the total volume seen in 2020 by the end of Q3 2021, according to researchers at the WatchGuard Threat Lab. In its latest report, WatchGuard also highlights that a significant percentage of malware continues to arrive over encrypted connections.

While zero-day malware increased by just 3% to 67.2% in Q3 2021, the percentage of malware that arrived via Transport Layer Security (TLS) jumped from 31.6% to 47%. Data shows that many organisations are not decrypting these connections and therefore have poor visibility into the amount of malware hitting their networks.

End Users Remain Organisations' Biggest Security Risk

With the rapid adoption of hybrid working environments and increased attacks, IT and security professionals worry that future data breaches will most likely be the result of end users who are negligent of or break security policy, according to a recent Dark Reading survey. The percentage of respondents in Dark Reading's 2021 Strategic Security Survey who perceive users breaking policy as the biggest risk fell slightly, however, from 51% in 2020 to 48% in 2021. Other potential issues involving end users showed improvements as well, with social engineering falling in concern from 20% to 15% and remote work worries halving from 26% to 13%.

While this trend is positive, it's unclear where the increased confidence comes from, since more people now report ineffective end-user security awareness training (11%, to 2020's 7%).

Respondents shared their heightened concern about well-funded attacks. In 2021, 25% predicted an attack targeted at their organisations (a rise from 2020, when 20% said the same), and fear of a nation-state-sponsored action rose to 16% from 9% the year before. Yet only 16% reported sophisticated, automated malware as a top concern, a 10% drop from 2020, and fear of a gap between security and IT advances only merited 9%. A tiny 3% worried that their security tools wouldn't work well together, dropping from the previous year's 10%.

Supply Chain Disruptions Rose In 2021

56% of businesses experienced more supply chain disruptions in 2021 than 2020, a Hubs report reveals.

Last year was marked by a number of challenges, including computer chip shortages, port congestion, the ongoing impacts of COVID-19, logistics impediments, and energy crises, though with every hurdle faced, solutions are being sought. It is increasingly clear that while certain risks are hard to anticipate and difficult to plan for, it is possible to mitigate the effects of supply chain disruptions by establishing a robust and agile supply chain.

Over 98% of global companies are now planning to boost the resilience of their manufacturing supply chains, however, 37% have yet to implement any measures. As businesses develop long term strategies, over 57% of companies say diversification of their supply chains is the most effective way of building resilience. This report explores last year’s most disruptive events, how disruptions have changed over time, industry trends and strategies for strengthening manufacturing supply chains.

Red Cross Begs Attackers Not to Leak Stolen Data for 515K People

A cyber attack forced the Red Cross to shut down IT systems running the Restoring Family Links system, which reunites families fractured by war, disaster or migration. UPDATE: The ICRC says it’s open to confidentially communicating with the attacker.

The Red Cross is imploring threat actors to show mercy by abstaining from leaking data belonging to 515,000+ “highly vulnerable” people. The data was stolen from a program used to reunite family members split apart by war, disaster or migration.

“While we don’t know who is responsible for this attack, or why they carried it out, we do have this appeal to make to them,” Robert Mardini, the director general of the International Committee for the Red Cross (ICRC), said in a release on Wednesday. “Your actions could potentially cause yet more harm and pain to those who have already endured untold suffering. The real people, the real families behind the information you now have are among the world’s least powerful. Please do the right thing. Do not share, sell, leak or otherwise use this data.”

DHL Dethrones Microsoft As Most Imitated Brand In Phishing Attacks

DHL was the most imitated brand in phishing campaigns throughout Q4 2021, pushing Microsoft to second place, and Google to fourth.

This isn't surprising considering that the final quarter of every year includes the Black Friday, Cyber Monday, and Christmas shopping season, so phishing lures based on package deliveries naturally increase.

DHL is an international package delivery and express mail service, delivering over 1.6 billion parcels per year.

As such, phishing campaigns impersonating the brand have good chances of reaching people who are waiting for a DHL package to arrive during the holiday season.

The specific lures range from a package that is stuck at customs and requires action for clearance to supposed tracking numbers that hide inside document attachments or embedded links.

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

Businesses Suffered 50% More Cyber Attack Attempts per Week in 2021

Cyberattack attempts reached an all-time high in the fourth quarter of 2021, jumping to 925 a week per organisation, partly due to attempts stemming from the Log4j vulnerability, according to new data.

Check Point Research on Monday reported that it found 50% more attack attempts per week on corporate networks globally in calendar year 2021 compared with 2020.

The researchers define a cyberattack attempt as a single isolated cyber occurrence that could be at any point in the attack chain — scanning/exploiting vulnerabilities, sending phishing emails, malicious website access, malicious file downloads (from Web/email), second-stage downloads, and command-and-control communications.

https://www.darkreading.com/attacks-breaches/corporate-networks-saw-50-more-attacks-per-week-in-2021-

Cyber Attacks Against MSPs Jump 67%

Cyber attacks spiked by 50 percent in 2021 as compared to 2020, aided by millions of attacks in December by hackers attempting to exploit the Log4J vulnerability, according to a Check Point Software Technologies research report.

In terming 2021 a “record breaking year,” the security provider pointed to a worldwide peak of 925 cyber attacks per organisation weekly and an October 2021 measure that showed a 40 percent increase in cyberattacks, with one out of every 61 entities hit by ransomware each week. The number of cyberattacks on managed service providers (MSPs) and internet service providers (ISPs) rose by nearly 70 percent year over year.

https://www.msspalert.com/cybersecurity-news/cyberattacks-vs-msps-skyrocket/

SMEs Still An Easy Target For Cyber Criminals

Cyber crime continues to be a major concern, with 51% of SMEs experiencing a cyber security breach, a Markel Direct survey reveals.

In this survey that polled 1000 respondents, Markel Direct explored the issue of cybercrime and its impact on the self-employed and SMEs. The survey found the most common cybersecurity attacks were malware/virus related (24%) followed by a data breach (16%) and phishing attack (15%), with 68% reporting the cost of their breach was up to £5,000.

This comes after the latest Quarterly Fraud and Cyber Crime Report revealed that Britons lost over £1 billion in the first six months of 2021, due to the considerable increase in fraudulent activity.

World Economic Forum: Cyber Security Failures an Increasing Global Threat

Cybersecurity was once again identified as a major short and medium-term threat to the world in this year’s World Economic Forum’s (WEF’s) The Global Risk Report. The analysis was based on insights from nearly 1000 global experts and leaders who responded to the WEF’s Global Risks Perception Survey (GRPS).

Perhaps unsurprisingly, environmental issues like climate action failure and extreme weather ranked highest on the risks facing the world over the short (0-2 years), medium (2-5 years) and long-term (5-10 years). In addition, a number of challenges exacerbated by the pandemic, such as livelihood crises, infectious diseases and mental health deterioration, also scored highly. Overall, this added up to a pessimistic assessment, with 84.2% of respondents stating they were either “worried” or “concerned” about the global outlook.

Digital challenges, such as “cyber security failures,” were also viewed as a significant and growing problem to the world. Nearly one in five (19.5%) respondents believe cybersecurity failures will be a critical threat to the world in just the next 0-2 years, and 14.6% said it would be in 2-5 years

Microsoft Faces Wormable, Critical RCE Bug & 6 Zero-Days

Microsoft started 2022 with a large January Patch Tuesday update covering nine critical CVEs, including a self-propagator with a 9.8 CVSS score.

Microsoft has addressed a total of 97 security vulnerabilities in its January 2022 Patch Tuesday update – nine of them rated critical – including six that are listed as publicly known zero-days.

The fixes cover a swath of the computing giant’s portfolio, including: Microsoft Windows and Windows Components, Microsoft Edge (Chromium-based), Exchange Server, Microsoft Office and Office Components, SharePoint Server, .NET Framework, Microsoft Dynamics, Open-Source Software, Windows Hyper-V, Windows Defender, and Windows Remote Desktop Protocol (RDP).

Russia Arrests REvil Ransomware Gang Responsible for High-Profile Cyber Attacks

In an unprecedented move, Russia's Federal Security Service (FSB), the country's principal security agency, on Friday disclosed that it arrested several members belonging to the notorious REvil ransomware gang and neutralized its operations.

The surprise takedown, which it said was carried out at the request of the US authorities, saw the law enforcement agency conduct raids at 25 addresses in the cities of Moscow, St. Petersburg, Moscow, Leningrad and Lipetsk regions that belonged to 14 suspected members of the organised cyber crime syndicate.

"In order to implement the criminal plan, these persons developed malicious software, organised the theft of funds from the bank accounts of foreign citizens and their cashing, including through the purchase of expensive goods on the Internet," the FSB said in a statement.

In addition, the FSB seized over 426 million rubles, including in cryptocurrency, $600,000, €500,000, as well as computer equipment, crypto wallets used to commit crimes, and 20 luxury cars that were purchased with money obtained by illicit means.

North Korea Hackers Stole $400m Of Cryptocurrency In 2021, Report Says

North Korean hackers stole almost $400m (£291m) worth of digital assets in at least seven attacks on cryptocurrency platforms last year, a report claims.

Blockchain analysis company Chainalysis said it was one of most successful years on record for cyber-criminals in the closed east Asian state.

The attacks mainly targeted investment firms and centralised exchanges.

North Korea has routinely denied being involved in hack attacks attributed to them.

"From 2020 to 2021, the number of North Korean-linked hacks jumped from four to seven, and the value extracted from these hacks grew by 40%," Chainalysis said in a report.

No Lights, No Heat, No Money - That's Life In Ukraine During Cyber Warfare

Hackers who defaced and interrupted access to numerous Ukrainian government websites on Friday could be setting the stage for more serious cyberattacks that would disrupt the lives of ordinary Ukrainians, experts said.

"As tensions grow, we can expect more aggressive cyber activity in Ukraine and potentially elsewhere," said John Hultquist, an intelligence analyst at US cyber security company Mandiant, possibly including "destructive attacks that target critical infrastructure."

"Organisations need to begin preparing," Hultquist added.

Intrusions by hackers on hospitals, power utility companies, and the financial system were until recently rare. But organised cyber criminals, many of them living in Russia, have gone after institutions aggressively in the past two years with ransomware, freezing data and computerized equipment needed to care for hospital patients.

In some cases, those extortion attacks have led to patient deaths, according to litigation, media reports and medical professionals.

Ukrainian Police Arrest Five Members Of Ransomware Affiliate

Ukrainian police announced the arrest of five members of a ransomware affiliate on Thursday, noting that the group was behind attacks on more than 50 companies across Europe and the US.

In a statement, both the Ukrainian Security Service and Ukrainian Cyber Police said the group made at least $1 million through their attacks on the companies.

US and UK law enforcement officials worked with Ukrainian officials on the operation.

Officials said the leader of the group was a 36-year-old who worked with his wife and three other people out of Kyiv. The five are facing a variety of charges in Ukraine related to money laundering, hacking, and selling malware.

One of the people charged is wanted by law enforcement agencies in UK after "using a virus to obtain bank card details of the customers of British banks," according to the police statement.

The bank card details were used to buy things online that were then resold.

Fingers Point To Lazarus, Cobalt, Fin7 As Key Hacking Groups Attacking Finance Industry

The Lazarus, Cobalt, and FIN7 hacking groups have been labeled as the most prevalent threat actors striking financial organisations today.

According to "Follow the Money," a new report (.PDF) published on the financial sector by Outpost24's Blueliv on Thursday, members of these groups are the major culprits of theft and fraud in the industry today.

The financial sector has always been, and possibly always will be, a key target for cybercriminal groups. Organisations in this area are often custodians of sensitive personally identifiable information (PII) belonging to customers and clients, financial accounts, and cash.

They also often underpin the economy: if a payment processor or bank's systems go down due to malware, this can cause irreparable harm not only to the victim company in question, but this can also have severe financial and operational consequences for customers.

Ransomware, Supply Chain, And Deepfakes: The Top Threats The Finance Industry Needs To Prepare For

The finance industry is constantly targeted by numerous threat actors, and they are always innovating and trying new techniques (such as deepfakes) to outsmart security teams and breach an organisation’s network.

In addition to that, there is currently a huge demand for data and new tools on the dark web. In fact, users are selling access to point-of-sale (PoS) terminals and login details to the websites of financial services organisations all the time.

How can financial organisations protect themselves from existing threats and combat new ones at the same time?

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

Microsoft Sees Rampant Log4j Exploit Attempts, Testing

Microsoft says it’s only going to get worse: It’s seen state-sponsored and cyber-criminal attackers probing systems for the Log4Shell flaw through the end of December.

No surprise here: The holidays bought no Log4Shell relief.

Threat actors vigorously launched exploit attempts and testing during the last weeks of December, Microsoft said on Monday, in the latest update to its landing page and guidance around the flaws in Apache’s Log4j logging library.

“We have observed many existing attackers adding exploits of these vulnerabilities in their existing malware kits and tactics, from coin miners to hands-on-keyboard attacks,” according to Microsoft.

https://threatpost.com/microsoft-rampant-log4j-exploits-testing/177358/

Warning: Log4j Still Lurks Where Dependency Analysis Can’t Find It

The best programming practice to include a third-party library in source code is to use the import command. It is the easiest way to do it, and it is also the way that most dependency analysis programs work to determine if a vulnerable library is in play. But any time code is included without calling it as an external package, traditional dependency analysis might not be enough to find it — including when Java coders use a common trick to resolve conflicting dependencies during the design process.

A new study by jFrog found that 400 packages on repository Maven Central used Log4j code without calling it as an external package. Around a third of that came from fat jars — jar files that include all external dependencies to make a more efficient product. The remainder came from directly inserting Log4j code into the source code, including shading, a work-around used when two or more dependencies call different versions of the same library in a way that might conflict.

While 400 may not seem like a lot for Maven Central, where Google found 17,000 packages implementing the vulnerable Log4j library, some of the 400 packages unearthed by JFrog are widely used.

Hackers Sending Malware-Filled USB Sticks to Companies Disguised as Presents

The "malicious USB stick" trick is old but apparently it's still wildly popular with the crooks.

Word to the wise: If a stranger ever offers you a random USB stick as a gift, best not to take it.

On Thursday, the FBI warned that a hacker group has been using the US mail to send malware-laden USB drives to companies in the defence, transportation and insurance industries. The criminals’ hope is that employees will be gullible enough to stick them into their computers, thus creating the opportunity for ransomware attacks or the deployment of other malicious software, The Record reports.

The hacker group behind this bad behaviour—a group called FIN7—has gone to great lengths to make their parcels appear innocuous. In some cases, packages were dressed up as if they were sent by the US Department of Health and Human Services, with notes explaining that the drives contained important information about COVID-19 guidelines. In other cases, they were delivered as if they had been sent via Amazon, along with a “decorative gift box containing a fraudulent thank you letter, counterfeit gift card, and a USB,” according to the FBI warning.

https://gizmodo.com/hackers-have-been-sending-malware-filled-usb-sticks-to-1848323578

Patch Systems Vulnerable To Critical Log4j Flaws, UK And US Officials Warn

One of the highest-severity vulnerabilities in years, Log4Shell remains under attack.

Criminals are actively exploiting the high-severity Log4Shell vulnerability on servers running VMware Horizon in an attempt to install malware that allows them to gain full control of affected systems, the UK’s publicly funded healthcare system is warning.

CVE-2021-44228 is one of the most severe vulnerabilities to come to light in the past few years. It resides in Log4J, a system-logging code library used in thousands if not millions of third-party applications and websites. That means there is a huge base of vulnerable systems. Additionally, the vulnerability is extremely easy to exploit and allows attackers to install Web shells, which provide a command window for executing highly privileged commands on hacked servers.

The remote-code execution flaw in Log4J came to light in December after exploit code was released before a patch was available. Malicious hackers quickly began actively exploiting CVE-2021-44228 to compromise sensitive systems.

https://arstechnica.com/information-technology/2022/01/patch-systems-vulnerable-to-critical-log4j-flaws-uk-and-us-officials-warn/

‘Elephant Beetle’ Lurks For Months In Networks

The group blends into an environment before loading up trivial, thickly stacked, fraudulent financial transactions too tiny to be noticed but adding up to millions of dollars.

Researchers have identified a threat group that’s been quietly siphoning off millions of dollars from financial- and commerce-sector companies, spending months patiently studying their targets’ financial systems and slipping in fraudulent transactions amongst regular activity.

The Sygnia Incident Response team has been tracking the group, which it named Elephant Beetle, aka TG2003, for two years.

In a Wednesday report, the researchers called Elephant Beetle’s attack relentless, as the group has hidden “in plain sight” without the need to develop exploits.

https://threatpost.com/elephant-beetle-months-networks-financial/177393/

Sonicwall: Y2k22 Bug Hits Email Security, Firewall Products

SonicWall has confirmed today that some of its Email Security and firewall products have been hit by the Y2K22 bug, causing message log updates and junk box failures starting with January 1st, 2022.

The company says that email users and administrators will no longer be able to access the junk box or un-junk newly received emails on affected systems.

They will also no longer be able to trace incoming/outgoing emails using the message logs because they're no longer updated.

On January 2nd, SonicWall deployed updates to North American and European instances of Hosted Email Security, the company's cloud email security service.

It also released fixes for its on-premises Email Security Appliance (ES 10.0.15) and customers using firewalls with the Anti-Spam Junk Store functionality toggled on (Junk Store 7.6.9).

https://www.bleepingcomputer.com/news/security/sonicwall-y2k22-bug-hits-email-security-firewall-products/

Hackers Use Video Player To Steal Credit Cards From Over 100 Sites

Hackers used a cloud video hosting service to perform a supply chain attack on over one hundred real estate sites that injected malicious scripts to steal information inputted in website forms.

These scripts are known as skimmers or formjackers and are commonly injected into hacked websites to steal sensitive information entered into forms. Skimmers are commonly used on checkout pages for online stores to steal payment information.

In a new supply chain attack discovered by Palo Alto Networks Unit42, threat actors abused a cloud video hosting feature to inject skimmer code into a video player. When a website embeds that player, it embeds the malicious script, causing the site to become infected.

https://www.bleepingcomputer.com/news/security/hackers-use-video-player-to-steal-credit-cards-from-over-100-sites/

Cyber World Is Starting 2022 In Crisis Mode With The Log4j Bug

The cyber security world is starting off 2022 in crisis mode.

The newest culprit is the log4j software bug, which cyber security and Infrastructure Security Agency (CISA) Director Jen Easterly called “the most serious vulnerability I have seen in my decades-long career.” It forced many cyber security pros to work through the holidays to protect computer systems at Big Tech firms, large and small companies and government agencies.

But crises like log4j have become the norm rather than the exception during the past few years.

Last year kicked off with the SolarWinds hack — a Russian government operation that compromised reams of sensitive information from U.S. government agencies and corporations.

Digital threats of all sorts are growing far faster than the capability to defend against them. If past is prologue, 2022 is likely to be a year of big hacks, big threats and plenty more crises.

“We’re always in crisis is the long and short of it,” Jake Williams, a former National Security Agency (NSA) cyber operator and founder of the firm Rendition Infosec, told me. “Anyone looking for calm rather than the storm in cyber is in the wrong field.”

https://www.washingtonpost.com/politics/2022/01/03/cyber-world-is-starting-2022-crisis-mode-with-log4j-bug/

Everything You Need To Know About Ransomware Attacks and Gangs In 2022

Ransomware is a lucrative business for criminals. It is paying off, and it is working.

According to a recent Trend Micro report, a staggering 84% of US organisations experienced either a phishing or ransomware attack in the last year. The average ransomware payment was over $500,000.

Bad actors want to keep cashing in. So they’re going as far as creating ransomware kits as a service (Ransomware as a Service) to be sold on the dark web and even setting up fake companies to recruit potential employees.

Many ransomware gangs function like real companies — with marketing teams, websites, software development, user documentation, support forums and media relations.

If the “companies” run by ransomware gangs can operate with minimal expenses and mind-blowing revenues, what’s stopping them from growing in number and size?

Why the Log4j Vulnerability Makes Endpoint Visibility and Zero Trust Security More Important Than Ever

The Apache Log4j vulnerability is one of the most serious vulnerabilities in recent years—putting millions of devices at risk.

IT organisations worldwide are still reeling from the discovery of a major security vulnerability in Apache Log4j, an open-source logging utility embedded in countless internal and commercial applications.

By submitting a carefully constructed variable string to log4j, attackers can take control of any application that includes log4j. Suddenly, cyber criminals around the world have a blueprint for launching attacks on everything from retail store kiosks to mission-critical applications in hospitals.

If security teams overlook even one instance of log4j in their software, they give attackers an opportunity to issue system commands at will. Attackers can use those commands to install ransomware, exfiltrate data, shut down operations — the list goes on.

How should enterprises respond to this pervasive threat?

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

The Log4j Flaw Will Take Years to be Fully Addressed

More than 80% of Java packages affected by the vulnerability in the Apache Log4j library cannot be updated directly, and will require coordination between different project teams to address the flaw.

Shortly after the first vulnerability in the Apache Log4j library (CVE-2021-44228) was disclosed, Google's Open Source Insights Team surveyed all the Java packages in the Maven Central Repository "to determine the scope of the issue in the open source ecosystem of JVM based languages, and to track the ongoing efforts to mitigate the affected packages," say team members James Wetter and Nicky Ringland. The team estimates it could take years before the vulnerability is fully addressed within the Java ecosystem.

A significant part of the problem has to do with indirect dependencies. Direct dependencies, or the cases where package explicitly pulls log4j into the code, are relatively straightforward to fix, as the developer or project owner just has to update log4j to the latest version.

Copycat And Fad Hackers Will Be The Bane Of Supply Chain Security In 2022

Replicable attacks and a low barrier to entry will ensure the rate of supply chain attacks increases next year, cyber security researchers have warned.

The supply chain is a consistent attack vector for threat actors today. By compromising a centralized service, platform, or software, attackers can then either conduct widespread infiltration of the customers and clients of the original -- singular -- victim or may choose to cherry-pick from the most valuable potential targets.

This can save cyber criminals time and money, as one successful attack can open the door to potentially thousands of victims at once.

A ransomware attack levied against Kaseya in 2021 highlighted the disruption a supply chain-based attack can cause. Ransomware was deployed by exploiting a vulnerability in Kaseya's VSA software, leading to the compromise of multiple managed service providers (MSP) in Kaseya's customer base.

This Nightmare Incident Shows Why You Really Shouldn't Store Passwords In Your Browser

An infostealer is scooping up passwords stored in browsers, experts warn

An unnamed company was recently breached after an employee stored their corporate account password in their web browser, a new report suggests.

According to research from security company AhnLab, the employee was working from home on a device shared with other household members, which was already infected with Redline Stealer, an infostealing malware.

Although the computer was equipped with antivirus software, the malware was able to evade detection, before stealing the passwords stored in the victim's browser.

Kaspersky Research: 47% of Incident Response Requests Linked to Ransomware

This year — 2021 — marked a “new era of ransomware,” said Vladimir Kuskov, head of threat exploration at Russian cyber security company Kaspersky. This is reflected in security incident requests handled by Kaspersky’s Global Emergency Response Team (GERT) between January and November 2021.

Kaspersky reported 46.7 percent of the security incidents that GERT handled in the first 11 months of 2021 were related to ransomware. Comparatively, Kaspersky attributed ransomware to 37.9 percent of security incidents that GERT handled for all of 2020 and 34 percent for 2019.

In addition, the government and industrial sectors have been the most common targets for ransomware attacks in 2021 to date, Kaspersky indicated. These industries accounted for nearly 50 percent of ransomware-related incident response requests that GERT has handled.

Global Cyber Attacks from Nation-State Actors Posing Greater Threats

Casey Ellis, CTO at Bugcrowd, outlines how international relations have deteriorated into a new sort of Cold War, with espionage playing out in the cyber-domain.

The macro-trend I’m most alarmed by today is the fact that attackers don’t seem to care about getting caught anymore. We have seen an increase in temerity of attacks by nation-states, such as the Russian attack on SolarWinds, and seen their attack tactics shift from targeted, stealthy operations into opportunistic hacks for potential future uses, such as the attacks attributed to Hafnium.

Such a brazen approach hasn’t been a common tactic of nation-states in the past, but now seems to be the status quo. In part, this trend may also be due to a destabilization of the international relations climate stemming from COVID-19, as well as work-from-home forcing core business services out onto the internet to facilitate employee access.

Broadly speaking, we should see China as a rising cyber security threat on the international stage. That has been the case for some time in terms of their economic, defense and military posture, but 2021 has quite clearly demonstrated that the relationship has deteriorated into a sort of Cold War, with espionage playing out in the cyber-domain.

Y2k22 Bug Is Causing Microsoft Exchange Server To Fail Worldwide: FIP-FS Scan Engine Failed To Load

Company admins are having their New Year’s celebrations interrupted by reports that their Exchange Servers are failing with the error “FIP-FS Scan Engine failed to load – Can’t Convert “2201010001” to long (2022/01/01 00:00 UTC)“.

The issue appears to be due to Microsoft using the first two numbers of the update version to denote the year of the update, which caused the “long” version of the date to overflow.

At present, it seems the main workaround is to disable the anti-malware scanner on the Exchange Server by using Set-MalwareFilteringServer -BypassFiltering $True -identity <server name> and restarting the Microsoft Exchange Transport service.

It appears Microsoft has not acknowledged the issue yet, but if you are affected some peer support is available at Reddit here.

Update: Microsoft has now acknowledged the issue and is working on a fix

External Attackers Can Penetrate Most Local Company Networks

In 93% of cases, external attackers can breach the organisation’s network perimeter and gain access to local network resources, and it takes an average of two days to penetrate the company’s internal network. In 100% of companies analysed, an insider can gain full control over the infrastructure.

These are the results of a new research report by Positive Technologies, analyzing results of the company’s penetration testing projects carried out in the second half of 2020 and first half of 2021.

The study was conducted among financial organizations (29%), fuel and energy organizations (18%), government (16%), industrial (16%), IT companies (13%), and other sectors.

During the assessment of protection against external attacks, Positive Technologies experts managed to breach the network perimeter in 93% of cases. According to the company’s researchers, this figure has remained high for many years, confirming that criminals are able to breach almost any corporate infrastructure.

The Have I Been Pwned Service Now Includes 441K Accounts Stolen By RedLine Malware

The Have I Been Pwned data breach notification service now allows victims of the RedLine malware to check if their credentials have been stolen. The service now includes credentials for 441K accounts stolen by the popular info-stealer.

The RedLine malware allows operators to steal several information, including credentials, credit card data, cookies, autocomplete information stored in browsers, cryptocurrency wallets, credentials stored in VPN clients and FTP clients. The malicious code can also act as a first-stage malware.

Stolen data are stored in an archive (logs) before being uploaded to a server under the control of the attackers.

A few days ago the data breach hunter Bob Diachenko discovered an unsecured server exposing over 6 million RedLine logs containing data harvested between August and September 2021. The server is still accessible, but the researchers pointed out that threat actors abandoned it because the the number of logs is not increasing.

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 Criminals Shifting Focus: IT Sector Most Targeted In 2021

Darktrace reported that the IT and communications sector was globally the most targeted industry by cybercriminals in 2021.

Darktrace’s data is developed by ‘early indicator analysis’ that looks at the breadcrumbs of potential cyber-attacks at several stages before they are attributed to any particular actor and before they escalate into a full-blown crisis. Findings show that its artificial intelligence autonomously interrupted an average of 150,000 threats per week against the sector in 2021.

The IT and communications sector includes telecommunications providers, software developers, and managed security service providers, amongst others. There was also a growing trend of hackers targeting backup servers in an attempt to deliberately disable or corrupt backup files by deleting a single index file that would render all backups inaccessible. Attackers could then launch ransomware attacks against the clients of the backup vendor, preventing recovery and forcing payment.

In 2020, the most attacked industry was the financial and insurance sector, showing that cyber-criminals have shifted their focus over the last 12 months.

Over the last 12 months, it is clear that attackers are relentlessly trying to access the networks of trusted suppliers in the IT and communications sector. Quite simply, it is a better return on investment than, for example, going after one company in the financial services sector. SolarWinds and Kaseya are just two well-known and recent examples of this. Sadly, there is likely to be more in the near term.

The findings of this research mark one year since the compromise of US software company SolarWinds rattled the security industry. This landmark supply-chain attack made thousands of organisations vulnerable to infiltration by inserting malicious code into the Orion system. Over the last 12 months, there has been a continued spate of attacks against the IT and communications sector, including the high-profile attacks on Kaseya and Gitlab.

https://www.helpnetsecurity.com/2021/12/22/cybercriminals-it-sector/

New Ransomware Variants Flourish Amid Law Enforcement Actions

Ransomware groups continue to evolve their tactics and techniques to deploy file-encrypting malware on compromised systems, notwithstanding law enforcement's disruptive actions against the cyber crime gangs to prevent them from victimizing additional companies.

"Be it due to law enforcement, infighting amongst groups or people abandoning variants altogether, the RaaS [ransomware-as-a-service] groups dominating the ecosystem at this point in time are completely different than just a few months ago," Intel 471 researchers said in a report published this month. "Yet, even with the shift in the variants, ransomware incidents as a whole are still on the rise."

Sweeping law enforcement operations undertaken by government agencies in recent months have brought about rapid shifts in the RaaS landscape and turned the tables on ransomware syndicates like Avaddon, BlackMatter, Cl0p, DarkSide, Egregor, and REvil, forcing the actors to slow down or shut down their businesses altogether.

https://thehackernews.com/2021/12/new-ransomware-variants-flourish-amid.html

93% of Tested Networks Vulnerable to Breach, Pen Testers Find

Data from dozens of penetration tests and security assessments suggest nearly every organisation can be infiltrated by cyber attackers.

The vast majority of businesses can be compromised within a month by a motivated attacker using common techniques, such as compromising credential, exploiting known vulnerabilities in software and Web applications, or taking advantage of configuration flaws, according to an analysis of security assessments by Positive Technologies.

In 93% of cases, an external attacker could breach a target company's network and gain access to local devices and systems, the company's security service professionals found. In 71% of cases, the attacker could affect the businesses in a way deemed "unacceptable." For example, every bank tested by the security firm could be attacked in a way that disrupted business processes and reduced the quality of their service.

Dridex Malware Trolls Employees With Fake Job Termination Emails

A new Dridex malware phishing campaign is using fake employee termination emails as a lure to open a malicious Excel document, which then trolls the victim with a season's greeting message.

Dridex is a banking malware spread through malicious emails that was initially developed to steal online banking credentials. Over time, the developers evolved the malware to use different modules that provide additional malicious behaviour, such as installing other malware payloads, providing remote access to threat actors, or spreading to other devices on the network.

This malware was created by a hacking group known as Evil Corp, which is behind various ransomware operations, such as BitPaymer, DoppelPaymer, WastedLocker variants, and Grief. Due to this, Dridex infections are known to lead to ransomware attacks on compromised networks.

https://www.bleepingcomputer.com/news/security/dridex-malware-trolls-employees-with-fake-job-termination-emails/

More Than 35,000 Java Packages Impacted By Log4j Flaw, Google Warns

The Google Open Source Team scanned the Maven Central Java package repository and found that 35,863 packages (8% of the total) were using versions of the Apache Log4j library vulnerable to Log4Shell exploit and to the CVE-2021-45046 RCE.

“More than 35,000 Java packages, amounting to over 8% of the Maven Central repository (the most significant Java package repository), have been impacted by the recently disclosed log4j vulnerabilities (1, 2), with widespread fallout across the software industry.” reads the report published by Google. “As far as ecosystem impact goes, 8% is enormous.”

The Google experts used the Open Source Insights, a project used to determine open source dependencies, to assess all versions of all artifacts in the Maven Central Repository.

The experts pointed out that the direct dependencies account for around 7,000 of the affected packages. Most of the affected artifacts are related to indirect dependencies.

Since the vulnerability was disclosed, 13% of all vulnerable packages have been fixed (4,620).

https://securityaffairs.co/wordpress/125845/security/log4j-java-packages-flaws.html

Log4j Flaw: Attackers Are 'Actively Scanning Networks' Warns New Guidance, Joint Advisory from Cyber Agencies in US, Australia, Canada, New Zealand and the United Kingdom

A new informational Log4J advisory has been issued by cybersecurity leaders from the US, Australia, Canada, New Zealand and the United Kingdom. The guide includes technical details, mitigations and resources to address known vulnerabilities in the Apache Log4j software library.

The project is a joint effort by the US' Cybersecurity and Infrastructure Security Agency (CISA), FBI and NSA, as well as the Australian Cyber Security Centre (ACSC), Canadian Centre for Cyber Security (CCCS), Computer Emergency Response Team New Zealand (CERT NZ), New Zealand National Cyber Secure Centre (NZ NCSC), and the United Kingdom's National Cyber Security Centre (NCSC-UK).

The organisations said they issued the advisory in response to "active, worldwide exploitation by numerous threat actors, including malicious cyber threat actors." Numerous groups from North Korea, Iran, Turkey and China have been seen exploiting the vulnerability alongside a slate of ransomware groups and cybercriminal organisations.

Conti Ransomware Gang Has Full Log4Shell Attack Chain

The Conti gang was the first professional-grade, sophisticated ransomware group to weaponise Log4j2, now with a full attack chain.

The Conti ransomware gang, which last week became the first professional crimeware outfit to adopt and weaponize the Log4Shell vulnerability, has now built up a holistic attack chain.

The sophisticated Russia-based Conti group – which Palo Alto Networks has called “one of the most ruthless” of dozens of ransomware groups currently known to be active – was in the right place at the right time with the right tools when Log4Shell hit the scene 10 days ago, security firm Advanced Intelligence (AdvIntel) said in a report shared with Threatpost on Thursday.

As of Monday the attack chain has taken the following form, AdvIntel’s Yelisey Boguslavskiy told Threatpost: Emotet -> Cobalt Strike -> Human Exploitation -> (no ADMIN$ share) -> Kerberoast -> vCenter ESXi with log4shell scan for vCenter.

https://threatpost.com/conti-ransomware-gang-has-full-log4shell-attack-chain/177173/

Second Ransomware Family Exploiting Log4j Spotted In US, Europe

This was quickly followed by a second ransomware group when researchers found a second family of ransomware has been growing in usage for attack attempts that exploit the critical vulnerability in Apache Log4j, including in the US and Europe.

A number of researchers, including at cybersecurity giant Sophos, have now said they’ve observed the attempted deployment of a ransomware family known as TellYouThePass. Researchers have described TellYouThePass as an older and largely inactive ransomware family — which has been revived following the discovery of the vulnerability in the widely used Log4j logging software.

Threat actors steal $80 million per month with fake giveaways, surveys

Scammers are estimated to have made $80 million per month by impersonating popular brands asking people to participate in fake surveys or giveaways.

Researchers warn of this new trend in global fraud schemes involving targeted links to make investigation and take-down increasingly challenging.

According to current estimates, these massive campaigns resulted in an estimated $80,000,000 per month, stolen from 10 million people in 91 countries.

The scam themes are the typical and "trustworthy" fake surveys and giveaways from popular brands with the holiday season making targets more susceptible to fraudulent gift offerings.

According to a report by Group-IB, there are currently 60 known scam networks that use targeted links in their campaigns, impersonating 121 brands in false giveaways.

Each network uses an average of 70 different Internet domain names as part of their campaigns, but some find great success with fewer domains, which indicates that quality beats quantity when it comes to scams.

https://www.bleepingcomputer.com/news/security/threat-actors-steal-80-million-per-month-with-fake-giveaways-surveys/

Microsoft Teams might have a few serious security issues

Security researchers have discovered four separate vulnerabilities in Microsoft Teams that could be exploited by an attacker to spoof link previews, leak IP addresses and even access the software giant's internal services.

These discoveries were made by researchers at Positive Security who “stumbled upon” them while looking for a way to bypass the Same-Origin Policy (SOP) in Teams and Electron according to a new blog post. For those unfamiliar, SOP is a security mechanism found in browsers that helps stop websites from attacking one another.

During their investigation into the matter, the researchers found that they could bypass the SOP in Teams by abusing the link preview feature in Microsoft's video conferencing software by allowing the client to generate a link preview for the target page and then using either summary text or optical character recognition (OCR) on the preview image to extract information.

https://www.techradar.com/news/microsoft-teams-might-have-a-few-serious-security-issues

The Future of Work Has Changed, and Your Security Mindset Needs to Follow

VPNs have become a vulnerability that puts organisations at risk of cyber attacks.

When businesses first sent employees to work from home in March 2020 — thinking it'd only be for two weeks — they turned to quick fixes that would enable remote work for large numbers of people as quickly as possible. While these solutions solved the short-term challenge of allowing distributed workforces to connect to a company's network from anywhere, they're now becoming a security vulnerability that is putting organisations at risk of growing cyberattacks.

Now that almost two years have passed and work has fundamentally shifted, with fully or hybrid remote environments here to stay, business and security leaders need solutions that better fit their unique and increasingly complex needs. In fact, a new survey from Menlo Security has found that 75% of organisations are re-evaluating their security strategies for remote employees, exemplifying that accommodating remote work is a top priority for the majority of business leaders.

To successfully manage the risks that distributed workforces entail, leaders must shift their mindset away from the hub-and-spoke approach of providing connectivity to the entire network, instead segmenting access by each individual private application, wherever it is deployed, as threats of cyberattacks loom across all industries. As organisations grapple with the added security challenges that remote and hybrid work environments bring, adopting a zero-trust approach will be critical for end-to-end network and endpoint protection.

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

Employees Think They’re Safe From Cyber Threats On Company Devices

A research launched by Menlo Security reveals increased cyber security risks posed to employees and organisations during the 2021 holiday shopping season.

The research – which surveyed 2,000 employed people in the United States and the United Kingdom – found that while employees are concerned about threats and are taking some measures to mitigate them, they often have false confidence in their security posture.

There are now more threats to corporate devices and networks than ever as hybrid work models blur the boundaries between work and home. More than half of respondents (56% US; 53% UK) reported performing non-work-related tasks – such as online shopping – on company devices.

Furthermore, the survey found that 65% of people in the US (63% UK) are doing more online holiday shopping in 2021 compared to previous years, and nearly half of respondents (48% US; 45% UK), reported shopping for gifts this holiday season on a work-issued device such as a laptop or mobile phone.

Workers are also noticing a rise in cyber threats this holiday season, with 58% of respondents in the US (48% UK) observing an increase in scams and fraudulent messages, exemplifying that threats are rampant worldwide. This is worrying many people, as the vast majority of respondents (80% US & UK) report being somewhat to very concerned about their personal data being stolen while online shopping.

However, despite workers’ recognition and concern of cyber threats, 60% of people (65% UK) still believe they’re secure from cyberthreats if they’re using a company device.

https://www.helpnetsecurity.com/2021/12/14/employees-cybersecurity-risks/

Internet Is Scrambling To Fix Log4shell, The Worst Hack In History

Massive data breaches have become so common that we’ve gotten numb to reports detailing another hack or 0-day exploit. That doesn’t reduce the risk of such events happening, as the cat-and-mouse game between security experts and hackers continues. As some vulnerabilities get fixed, others pop up requiring attention from product and service providers. The newest one has a name that will not mean anything to most people. They call the hack Log4Shell in security briefings, which doesn’t sound very scary. But the new 0-day attack is so significant that some people see it as the worst internet hack in history.

Malicious individuals are already exploiting the Log4Shell attack, which allows them to get into computer systems and servers without a password. Security experts have seen Log4Shell in action in Minecraft, the popular game that Microsoft owns. A few lines of text passed around in a chat might be enough to penetrate the defences of a target computer. The same ease of access would allow hackers to go after any computer out there using the Log4J open-sourced java-based logging utility.

https://bgr.com/tech/internet-is-scrambling-to-fix-log4shell-the-worst-hack-in-history/

Apache Log4j Flaw: A Fukushima Moment for the Cyber Security Industry

Organisations around the world will be dealing with the long-tail consequences of this vulnerability, known as Log4Shell, for years to come.

The discovery of a critical flaw in the Apache Log4j software is nothing short of a Fukushima moment for the cybersecurity industry.

Ten years ago, an earthquake and subsequent tidal wave triggered the meltdown of the Fukushima nuclear power plant that continues to plague the region today. Similarly, the early exploitation of Log4j, during which attackers will go after the low-hanging fruit exposed by the vulnerability, will evolve over time to take the form of more complex attacks on more sensitive systems that have less exposure to the internet. And, just as Fukushima brought to light significant issues with longstanding processes in place at the plant, so too does the Log4j vulnerability, known as Log4Shell, highlight two crucial practices of concern:

·       How organisations capture and protect their massive troves of log data; and

·       The use of open-source code libraries as the building blocks for major enterprise applications.

The paradox of Log4j: the more you log, the worse it gets

We’re discovering new apps every minute which use Log4j in one way or another. It affects not only the code you build, but also the third-party systems you have in place. Everything from the new printer you’ve bought for the office to the ticketing system you’ve just deployed is potentially affected by this flaw. Some affected systems may be on premises, others may be hosted in the cloud but no matter where they are, the flaw is likely to have an impact.

https://www.theregister.com/2021/12/17/vmware_criticial_uem_flaw/

60% of UK Workers Have Been Victim of a Cyber-Attack, Yet Awareness Remains Low

There is a “dangerous” lack of awareness among UK workers towards cybersecurity, leaving businesses at risk of attacks, according to a new study by Armis. This is despite 60% of workers admitting they have fallen victim to a cyber-attack.

The nationwide survey of 2000 UK employees found that only around a quarter (27%) are aware of the associated cyber risks, while one in 10 (11%) don’t worry about them at all.

Even more worryingly, just one in five people said they paid for online security, putting businesses at high risk of attacks amid the shift to remote working during COVID-19.

The most prevalent types of attacks experienced by workers or their organisations were phishing (27%), data breaches (23%) and malware (20%).

The study also revealed growing concerns about the scale of the cyber-threats facing the UK. A large-scale cyber-attack was ranked as the fourth biggest future concern (21%) among the respondents, equal to the UK going to war. Two-fifths (40%) said they would like to see a minister for cyber security installed to ensure the issue is focused on more at a government level.

Russian-backed cyber-criminals were considered the biggest threat to the UK’s cybersecurity (20%) by the respondents, followed by financially motivated cyber-criminals (17%) and Chinese-backed cyber-criminals (16%).

Ransomware in 2022: We're All Screwed

Ransomware is now a primary threat for businesses, and with the past year or so considered the "golden era" for operators, cybersecurity experts believe this criminal enterprise will reach new heights in the future.

Kronos. Colonial Pipeline. JBS. Kaseya. These are only a handful of 2021's high-profile victims of threat groups including DarkSide, REvil, and BlackMatter.

According to Kela's analysis of dark web forum activity, the "perfect" prospective ransomware victim in the US will have a minimum annual revenue of $100 million and preferred access purchases include domain admin rights, as well as entry into Remote Desktop Protocol (RDP) and Virtual Private Network (VPN) services.

Over the past few years, we've seen ransomware operators evolve from disorganised splinter groups and individuals to highly sophisticated operations, with separate teams collaborating to target everything from SMBs to software supply chains.

Ransomware infection is no longer an end goal of a cyberattack. Instead, malware families in this arena -- including WannaCry, NotPetya, Ryuk, Cerber, and Cryptolocker -- can be one component of attacks designed to elicit a blackmail payment from a victim organisation.

https://www.zdnet.com/article/ransomware-in-2022-were-all-screwed/

Attacks on UK Firms Increase Five-Fold During Pandemic

Attacks on UK firms surged five-fold during the pandemic and now cost way more than the global average, according to Accenture.

The global consultancy polled 500 UK executives to compile its State of Cybersecurity Resilience 2021 study.

It found that large organisations experienced 885 attempted cyber-attacks in 2020 – up from 156 the previous year and more than triple the global average of 270.

They’re also more expensive than elsewhere. Accenture calculated that incidents and breaches cost over £1.3m a year – £350,000 more than the global average.

Over 80% of respondents said the cost of staying ahead of cyber-criminals is unsustainable, a fifth more than the previous year, and a quarter said they’ve been forced to increase cybersecurity budgets by 10% or more.

Worryingly, supply chain attacks accounted for 64% of breaches in the UK last year, up by a quarter (26%) from the previous year.

The Log4J Software Flaw Is ‘Christmas Come Early’ for Cyber Criminals

Researchers have just identified a security flaw in a software program called Log4J, widely used by a host of private, commercial and government entities to record details ranging from usernames and passwords to credit card transactions. Since the glitch was found last weekend, the cybersecurity community has been scrambling to protect applications, services, infrastructure and even Internet of Things devices from criminals—who are already taking advantage of the vulnerability.

“For cybercriminals this is Christmas come early, because the sky’s the limit,” says Theresa Payton, a former White House chief information officer and the CEO of Fortalice Solutions, a cybersecurity consulting company. “They’re really only limited by their imagination, their technical know-how and their own ability to exploit this flaw.” Payton spoke with Scientific American about what Log4J does, how criminals can use its newly discovered weakness, and what it will take to repair the problem.

Why Cloud Storage Isn't Immune to Ransomware

Ransomware is the flavour of the month for cybercriminals. The FBI reports that ransomware attacks rose 20% and losses almost tripled in 2020. And our increased use of the cloud may have played a part in that spike. A survey of CISOs conducted by IDC earlier this year found that 98% of their companies suffered at least one cloud data breach in the previous 18 months as opposed to 79% last year, and numbers got worse the more exposure they had to the cloud.

Organisations now use hundreds of cloud-based apps, which adds thousands of new identities logging in to their systems. This opens almost unlimited possibilities for hackers. Even if cloud vendors have their own identity and access management controls, vulnerabilities will emerge. In fact, recent research into cloud security found that over 70% of organisations had machines open to the public that were linked to identities whose permissions were vulnerable, under the right conditions, to being exploited to launch ransomware attacks.

A number of reasons could explain why security falls through the cracks of many cloud systems, and leaves them more vulnerable to ransomware attacks.

400 Banks’ Customers Targeted with Anubis Trojan

Customers of Chase, Wells Fargo, Bank of America and Capital One, along with nearly 400 other financial institutions, are being targeted by a malicious app disguised to look like the official account management platform for French telecom company Orange S.A.

Researchers say this is just the beginning.

Once downloaded, the malware – a variant of banking trojan Anubis – steals the user’s personal data to rip them off, researchers at Lookout warned in a new report. And it’s not just customers of big banks at risk, the researchers added: Virtual payment platforms and crypto wallets are also being targeted.

“As a banking trojan malware, Anubis’ goal is to collect significant data about the victim from their mobile device for financial gain,” the Lookout report said. “This is done by intercepting SMSs, keylogging, file exfiltration, screen monitoring, GPS data collection and abuse of the device’s accessibility services.”

Sites Hacked With Credit Card Stealers Undetected For Months

Threat actors are gearing up for the holidays with credit card skimming attacks remaining undetected for months as payment information is stolen from customers.

Magecart skimming is an attack that involves the injection of malicious JavaScript code on a target website, which runs when the visitor is at the checkout page.

The code can steal payment details such as credit card number, holder name, addresses, and CVV, and send them to the actor.

Threat actors may then use this information for purchasing goods online or sold to other actors on underground forums and dark web marketplaces known as "carding" sites.

‘Don’t get scammed online this Christmas’ - Guernsey Press 17 December 2021

‘Don’t get scammed online this Christmas’ - Guernsey Press 17 December 2021

‘Don’t get scammed online this Christmas’

https://guernseypress.com/news/2021/12/17/dont-get-scammed-online-this-christmas/

Bruce McDougall, a director at local firm Black Arrow Cyber Consulting, pictured, said online shopping was the norm for many people and that trend had been further accelerated due to the Covid-19 pandemic.

But he urged people to take care when shopping online.

‘People accessing and buying from websites that they do not know run a greater chance of being the victim of an attack,’ said Mr McDougall.

‘Some websites give you the opportunity to sign in using your Google or Facebook account, but that is sometimes a fake screen that allows the attacker to skim off your credentials and then use them maliciously.’

A lot of people also use the same email address and password for different sites – which means that if an attacker knows a person’s log-on details for Facebook, they could try to use those same credentials to access that individual’s email account or Amazon account.

He said that there were three simple actions that could help increase security online.

‘Use multi-factor authentication. This is where you have to enter more than one piece of information to confirm your identity. For example, in addition to entering your username and password, you would enter a code that is generated from your phone.

‘If you have to use your fingerprint to access the phone that will give you the code, then that is an even greater level of security.

‘So, even if the attacker has harvested your username and password, they cannot access your account because they do not have your phone with the code.’

Using a different password for each website and account is also important.

‘Never recycle passwords. Follow the current best practice, which is to use a string of three random words, but make sure this is not text from a song or other well-known phrase.

‘Surprisingly, it can take years for a computer to crack a password made up of three random words. The problem is that many people try to create a complicated password themselves but in reality they are following a predictable pattern that attackers already know.’

Finally, Mr McDougall said that when making payments online, people should use their credit card rather than their debit card to get better buyer protection.

‘Some providers can give you a disposable single-use virtual credit card that you can use for purchases online, which means that even if the card number falls into the wrong hands, they cannot use the number to extract money from you.’

Black Arrow Cyber Advisory – Java Log4Shell Vulnerability – The Maximum Severity Christmas Humbug Likely To Affect Businesses

Black Arrow Cyber Advisory – Java Log4Shell Vulnerability – The Maximum Severity Christmas Humbug Like To Affect Every Business

Black Arrow Cyber Advisory – Java Log4Shell Vulnerability – The Maximum Severity Christmas Humbug

Executive Summary

Log4Shell, a critical zero-day actively exploited in the wild, has been found after a series of Minecraft servers fell victim. The bug impacts Java, an almost ubiquitous software that’s found in billions of devices across the globe, from the enterprise to the home. In an extremely rare but warranted move, Log4Shell has been given a 10 out of 10 on the Common Vulnerability Scoring System (CVSS) scale, owing to its ability to be remotely executed and the potential for pandemic level damage. 

What’s the risk to my business?

Java report their use on billions of devices, from computers, printers, routers and mobile phones to cash machines, ticket machines and credit card readers – the list is endless. The likelihood of a device running Java in your environment somewhere is high.

What can I do?

Discuss with your 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.

Technical Summary

The bug, tracked as CVE-2021-44228, was first discovered when a remote-code attack compromised a series of Minecraft servers, one of the most popular Java-based games of all time. The source of the bug was Log4J, a logging utility used by millions of applets across billions of devices. Using the vulnerability, threat actors can craft a request to force the applet to interpret a log as a URL, which is then fetched and executed with full privileges. The exploit can be triggered inside text using “${}”, allowing for their injection in commonly logged attributes like user agents.

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

Beware Of Ransomware Attacks Between Christmas And New Year’s!

Darktrace reported that its security researchers discovered a 30% increase in the average number of attempted ransomware attacks globally over the holiday season in every consecutive year from 2018 to 2020 compared to the monthly average.

The researchers also observed a 70% average increase in attempted ransomware attacks in November and December compared to January and February. Following a record number of ransomware attacks this year, the company expects the spike to be higher over the 2021 holiday period.

https://www.helpnetsecurity.com/2021/12/09/ransomware-attacks-holiday/

Why Holidays Put Your Company at Risk of Cyber Attack (And How to Take Precautions)

It is a time when many are thinking of their families and loved ones, time off work, and gift-giving – the holidays. However, while many have their minds outside the realm of work during the holiday season, often, this is when attackers plan their most sinister attacks.

So how can you take precautions to protect your organisation during these times?

Attackers today do not have a soft spot for businesses and give companies a break at any time of the year, especially not during holidays. On the contrary, any time of the year where companies may be less prepared to fend off a cyberattack is an opportunity for successful compromise. As a result, the holidays put your company at a higher risk of cyberattack.

https://thehackernews.com/2021/12/why-holidays-put-your-company-at-risk.html

Security Experts Sound Alarm on Zero-Day in Widely Used Log4j Tool

Security experts are sounding the equivalent of a five-alarm fire on a critical new zero-day vulnerability in Log4j, a logging framework that is ubiquitously present in Java software.

The flaw (CVE-2021-44228) could allow remote attackers to run arbitrary code on any application that uses Log4j and is already being actively exploited. Some vendors have observed mass scanning activity — presumably by threat actors — for vulnerable applications, and there are some reports of exploit activity against organisations. Attacks against the flaw take little skill to execute and are being fueled by proof-of-concept code in the wild.

https://www.darkreading.com/vulnerabilities-threats/security-experts-sound-alarm-on-zero-day-in-widely-used-log4j-tool

SolarWinds Attackers Spotted Using New Tactics, Malware

One year after the disruptive supply-chain attacks, researchers have observed two new clusters of activity from the Russia-based actors that signal a significant threat may be brewing.

One year after the notorious and far-reaching SolarWinds supply-chain attacks, its orchestrators are on the offensive again. Researchers said they’ve seen the threat group – which Microsoft refers to as “Nobelium” and which is linked to Russia’s spy agency – compromising global business and government targets with novel tactics and custom malware, stealing data and moving laterally across networks.

https://threatpost.com/solarwinds-attackers-new-tactics-malware/176818/

Cyber Crime Supply Chain: Fuelling The Rise In Ransomware

Trend Micro released a research detailing the murky cybercrime supply chain behind much of the recent surge in ransomware attacks. Demand has increased so much over the past two years that many cybercriminal markets now have their own “Access-as-a-Service” sections.

https://www.helpnetsecurity.com/2021/12/06/cybercrime-supply-chain/

Weak Passwords Caused 30% Of Security Breaches

A recent survey assessed the risk factors associated with password management and how to safeguard them from attacks or breaches. The results revealed that 30% of respondents reported password leaks and security breaches as a result of poor password practices. Respondees admitted to making poor password choices, such as sharing them with colleagues, family members or friends; writing them on sticky notes, papers, planners; re-using passwords across multiple sites and only changing them when prompted.

Consequently, researchers revealed some of the best password practices to create unhackable passwords. These practices include using secure VPNs, two-factor authentication, using a password management software and creating unique passwords that aren’t easily deduced .

https://www.itsecurityguru.org/2021/12/10/weak-passwords-caused-30-of-security-breaches/

Work-from-Anywhere Requires "Work-from-Anywhere Security"

Securing today's expanding networks often includes adding additional technologies to an already overburdened security environment. With organisations already struggling to manage an average of 45 security tools, with each incident requiring coordination across 19 different devices, adding new technologies to the mix may be the straw that breaks the camel's back.

The most recent example of the rapid expansion of the network's attack surface has been remote work. The COVID-19 pandemic accelerated the need for a work-from-anywhere (WFA) strategy. And now, as workers begin to return to the office, a hybrid approach to work has become the new status quo. According to Accenture, 83% of workers prefer a hybrid work model that allows them to work remotely between 25% and 75% of the time. And businesses are listening. 63% of high-revenue growth companies have already enabled productivity anywhere workforce models.

One of the biggest security challenges of a hybrid workforce is that employees need to move seamlessly between the corporate office, their home network, and other remote locations. Applications, whether deployed in the data centre, SaaS, or cloud, not only need to be available from anywhere, but user experience—and security—needs to be consistent from any location as well.

https://www.securityweek.com/work-anywhere-requires-work-anywhere-security

Just 3% of UK Firms Escaped a Supply Chain Breach in 2021

Some 97% of UK organisations suffered a supply chain breach over the past year, up from 82% in 2020 and the second highest figure globally, according to BlueVoyant.

The security firm polled 1200 C-level executives with responsibility for managing risk in supply chains, across the UK, US, Singapore, Canada, Germany and the Netherlands.

UK firms also experienced a higher-than-average percentage of breaches: 59% suffered between two and five supply chain incidents compared to an overall average of 49%. The average number of breaches in the country grew from 2.64 in 2020 to 3.57 in 2021.

Perhaps unsurprisingly given these figures, only a quarter (27%) of UK respondents said they consider third-party cyber risk a key priority versus a 42% global average.

Critical Flaw In ManageEngine Desktop Central MSP Tool Exploited In The Wild

News of this latest zero-day vulnerability comes after hackers exploited at least two other flaws in ManageEngine products this year. Attacks against MSPs and their tools have seen a rise over the past several years due to hackers realizing that compromising such organisations can provide an easy way into the networks of thousands of businesses that rely on them to manage their IT assets.

New Financial Services Industry Report Reveals Major Gaps in Storage and Backup Security

Continuity™, the first dedicated storage and backup security provider, this week announced findings from its Security Intelligence Report: Analysis of Storage and Backup Security in the Financial Services & Banking Sector. This extensive study – the first of its kind – explores the security posture of storage and backup environments in the global financial services industry.

The survey of 200 financial services firms and banks from 45 countries revealed that most of these organisations have not yet reached a satisfactory level of storage and backup maturity. Notably, more than half (52%) of the respondents were not strongly confident about their storage and backup security, and a quarter (25%) noted they were significantly concerned (low or no confidence).

https://www.darkreading.com/attacks-breaches/new-financial-services-industry-report-reveals-major-gaps-in-storage-and-backup-security

UK’s Poor Cyber Risk Planning Could “Wreak Havoc”

The UK’s long-term risk planning is under-powered and could expose the nation if it is struck by a serious cyber-threat, a new House of Lords (HoL) report has found.

The study, Preparing for Extreme Risks: Building a Resilient Society, was produced by the upper chamber’s Select Committee on Risk Assessment and Risk Planning after interviews with 85 expert witnesses.

It claimed that the government spends too much of its time reacting to crises and emergencies, neglecting the kind of long-term planning which would have prepared the country better for the COVID-19 pandemic.

“The UK’s unpreparedness to manage the outbreak of the COVID-19 virus was and is clear. More broadly, our inquiry has analyzed the UK’s risk assessment process and found that our current system is deficient at assessing and addressing future threats and hazards,” it argued.

“However, pandemics are only one of a number of extreme risks facing the UK. Severe space weather events could render smart technologies on which much of society relies inoperable for weeks or longer; this would include GPS, the internet, communications systems and power supplies. A cyber or physical attack on our critical national infrastructure could wreak havoc.”

Black Arrow Cyber Advisory – Critical SonicWall VPN Bug Allows Remote Unauthenticated Takeover

Black Arrow Cyber Advisory – Critical SonicWall VPN Bug Allows Remote Unauthenticated Takeover

Black Arrow Cyber Advisory – Critical SonicWall VPN Bug Allows Remote Unauthenticated Takeover

Executive Summary

SonicWall, a security vendor best known for their hardware appliances, is the subject of a critical advisory relating to its Secure Mobile Access (SMA) 100 series VPN appliances. The SMA 100 series provides secured end-to-end remote access to corporate networks and resources in a variety of environments, such as on-premises, hybrid or cloud infrastructure. The SMA 100 also provides policy driven access control, based on trusted users and devices.

The bug, rated a 9.8 out of 10 on the CVSS scale, allows a remote attacker to authenticate as “nobody”, effectively granting them the lowest level of access to the device. As such, an attacker would be able to modify policies, alter security settings or launch additional attacks from the compromised device.

What’s the risk to my business?

If you or your IT provider use the SonicWall SMA 100 appliance, the risk could be high. CVSS scores of 9.0 and higher carry a “fix immediately” flag, as any attack capable of remote execution provides an attractive target to bad actors. As firewalls and other perimeter security devices generally form the first line of defence, and protect a huge quantity of assets, compromising one can facilitate any number of additional attacks.

What can I do?

Speak to your IT service provider or IT team to find out if the SMA 100 is used in your environment. SonicWall have urged users to patch and continue to patch their devices, as SonicWall have been the subject of numerous attacks in recent years.

Technical Summary

The vulnerability – CVE-2021-20038 – has been found in the string concatenate function strcat(), which is used when handling environment variables in a HTTP GET method. The bug runs under the Apache httpd server, allowing attackers to run a stack-based buffer overflow to result in code execution.

A complete list of impacted devices can be found on SonicWall’s website.

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

Double Extortion Ransomware Victims Soar 935%

Researchers have recorded a 935% year-on-year increase in double extortion attacks, with data from over 2300 companies posted onto ransomware extortion sites.

Group-IB’s Hi-Tech Crime Trends 2021/2022 report covers the period from the second half of 2020 to the first half of 2021.

During that time, an “unholy alliance” of initial access brokers and ransomware-as-a-service (RaaS) affiliate programs has led to a surge in breaches, it claimed.

In total, the number of breach victims on ransomware data leak sites surged from 229 in the previous reporting period to 2371, Group-IB noted. During the same period, the number of leak sites more than doubled to 28, and the number of RaaS affiliates increased 19%, with 21 new groups discovered.

Group-IB warned that, even if victim organisations pay the ransom, their data often end up on these sites.

https://www.infosecurity-magazine.com/news/double-extortion-ransomware-soar/

MI6 Boss: Digital Attack Surface Growing "Exponentially"

Head of the Secret Intelligence Service (SIS), Richard Moore, explained in a rare speech this week that, unlike the character Q from the James Bond films, even MI6 cannot source all of its tech capabilities in-house.

New partners and tech capabilities will help address MI6’s four key priorities: Russia, China, Iran and global terrorism. It’s a challenge made more acute as technology rapidly advances, he said.

“The ‘digital attack surface’ that criminals, terrorists and hostile states threats seek to exploit against us is growing exponentially. We may experience more technological progress in the next ten years than in the last century, with a disruptive impact equal to the industrial revolution,” Moore argued.

https://www.infosecurity-magazine.com/news/mi6-digital-attack-surface-growing/

How Phishing Kits Are Enabling A New Legion Of Pro Phishers

Some cybercriminals are motivated by political ideals, others by malice or mischief, but most are only interested in cold, hard cash. To ensure their criminal endeavours are profitable, they need to balance the potential payday against the time, resources and risk required.

It’s no wonder then that so many use phishing as their default attack method. Malicious emails can be used to reach many targets with relative ease, and criminals can purchase ready-made phishing kits that bundle together everything they need for a lucrative campaign.

https://www.helpnetsecurity.com/2021/12/02/phishing-kits-pro/

Crooks Are Selling Access To Hacked Networks. Ransomware Gangs Are Their Biggest Customers

Dark web forum posts offering compromised VPN, RDP credentials and other ways into networks have tripled in the last year.

There's been a surge in cyber criminals selling access to compromised corporate networks as hackers look to cash in on the demand for vulnerable networks from gangs looking to initiate ransomware attacks.

Researchers at cybersecurity company Group-IB analysed activity on underground forums and said there's been a sharp increase in the number of offers to sell access to compromised corporate networks, with the number of posts offering access tripling between 2020 and 2021

https://www.zdnet.com/article/theres-been-a-big-jump-in-crooks-selling-access-to-hacked-networks-ransomware-gangs-are-their-best-customers/

Omicron Phishing Scam Already Spotted in UK

The global pandemic has provided cover for all sorts of phishing scams over the past couple of years, and the rise in alarm over the spread of the latest COVID-19 variant, Omicron, is no exception.

As public health professionals across the globe grapple with what they fear could be an even more dangerous COVID-19 variant than Delta, threat actors have grabbed the opportunity to turn uncertainty into cash.

UK consumer watchdog “Which?” has raised the alarm that a new phishing scam, doctored up to look like official communications from the National Health Service (NHS), is targeting people with fraud offers for free PCR tests for the COVID-19 Omicron variant

https://threatpost.com/omicron-phishing-scam-uk/176771/

Phishing Remains the Most Common Cause of Data Breaches, Survey Says

Phishing, malware, and denial-of-service attacks remained the most common causes for data breaches in 2021. Data from Dark Reading’s latest Strategic Security Survey shows that more companies experienced a data breach over the past year due to phishing than any other cause. The percentage of organisations reporting a phishing-related breach is slightly higher in the 2021 survey (53%) than in the 2020 survey (51%). The survey found that malware was the second biggest cause of data breaches over the past year, as 41% of the respondents said they experienced a data breach where malware was the primary vector.

https://www.darkreading.com/edge-threat-monitor/phishing-remains-the-most-common-cause-of-data-breaches-survey-says

Ransomware Victims Increase Security Budgets Due To Surge In Attacks

As the end of 2021 approaches, there’s no doubt ransomware became a top cybersecurity concern across multiple industries.  Successful ransomware attacks like the Colonial Pipeline, which took down critical US infrastructure, and Kaseya, which hit over 1,500 companies in a single attack, became a popular topic in the news.

Research conducted by Cymulate, however, shows that despite the increase in the number of attacks this past year, overall victims suffered limited damage in both severity and duration. Potential victims have improved their level of preparedness, with 70% reporting an increase of awareness at the boardroom and business management level. The majority (55%) undertook proactive measures to prevent ransomware attacks before they could cause any significant damage, and many of those respondents (38%) prevented attacks even before they could cause any serious downtime. Only 14% of respondents that experienced an attack were down for a week or more.

https://venturebeat.com/2021/12/03/report-ransomware-victims-increase-security-budgets-due-to-surge-in-attacks/

Control Failures Are Behind A Growing Number Of Cyber Security Incidents

Data from a survey of 1,200 enterprise security leaders reveals that an increase in tools and manual reporting combined with control failures are contributing to the success of threats such as ransomware, which costs organisations an average of $1.85 million in recovery, according to Panaseer.

Currently, only 36% of security leaders feel very confident in their ability to prove controls were working as intended. This is despite 99% of respondents believing it’s valuable to know that all controls are fully deployed and operating within policy, and cybersecurity control failures are currently being listed as the top emerging risk in the latest Gartner Emerging Risks Monitor Report. Attacks only succeed when they hit systems that haven’t been patched or don’t have security controls monitoring them.

MI6 Spy Chief Says China, Russia, Iran Top UK Threat List

China, Russia and Iran pose three of the biggest threats to the U.K. in a fast-changing, unstable world, the head of Britain’s foreign intelligence agency said Tuesday.

MI6 chief Richard Moore said the three countries and international terrorism make up the “big four” security issues confronting Britain’s spies.

In his first public speech since becoming head of the Secret Intelligence Service, also known as MI6, in October 2020, Moore said China is the intelligence agency’s “single greatest priority” as the country’s leadership increasingly backs “bold and decisive action” to further its interests.

Calling China “an authoritarian state with different values than ours,” he said Beijing conducts “large-scale espionage operations” against the U.K. and its allies, tries to ”distort public discourse and political decision-making” and exports technology that enables a “web of authoritarian control” around the world.

Moore said the U.K. also continues “to face an acute threat from Russia.” He said Moscow has sponsored killing attempts, such as the poisoning of former spy Sergei Skripal in England in 2018, mounts cyber attacks and attempts to interfere in other countries’ democratic processes.
