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

Cloud Hosting Firm Loses All Customer Data After Ransomware Attack

CloudNordic, a Danish cloud hosting provider, has told customers to consider all of their data as having been lost following a ransomware infection that encrypted the large Danish cloud provider. The threat actors had destroyed the organisation’s backups, which prevented the firm from recovering effectively. The attack also impacted AzeroCloud, which is owned by the same company.

Worryingly, many organisations believe that having backups and using the cloud is enough for them to be able to recover from any cyber incident; unfortunately, as shown in the CloudNordic and AzeroCloud attacks, it is not enough. Organisations need to have a recovery plan in place which is tested and improved, to best strengthen themselves in the event of a cyber incident.

Would You Infect Others to Rid Yourself of Ransomware?

Hackers continually develop ransomware with new and creative attack methods that keep internet security professionals on their toes and pose challenges for people trying to detect threats. Victims of ransomware usually see messages asking them to pay for file access restoration; however, the Popcorn Time ransomware group takes a different approach to getting victims involved.

The Popcorn Time ransomware approach works via the referral method. The ransomware group is willing to give victims access to their files if they send the referral link to two other people, extending the attacker’s reach. Most people would hesitate to distribute a ransomware link through email, WhatsApp, or another method that is easy for victims to identify them as the perpetrators. Law enforcement bodies categorise ransomware attacks as crimes that come with hefty fines and prison time. Even those choosing to send the links to people they know face disastrous consequences beyond law enforcement, including the loss of jobs and relationships.

Artificial Intelligence and USBs Drive 8% Rise in Cyber Attacks

Checkpoint’s 2023 Mid-Year Security Report shows an 8% surge in global weekly cyber attacks during Q2, marking the most significant increase in two years. The report highlights the fusion of advanced artificial intelligence (AI) technology with traditional tools like USB devices used for disruptive cyber attacks.

Other significant findings include the evolution of ransomware tactics. The report found that ransomware groups are exploiting vulnerabilities in common corporate software and shifting focus from encrypting data to stealing it. USB devices have resurfaced as threats, employed by both state-affiliated groups and cyber-criminals to distribute malware globally. The misuse of AI has escalated, as attackers use generative AI tools for phishing emails, keystroke monitoring malware and basic ransomware code.

Ransomware Attacks Broke Records in July, Mainly Driven By One Group

A number of ransomware actors are utilising the threat of releasing sensitive data to get organisations to pay ransoms; in some cases this is combined with encryption to give the actor two avenues of payment. A report has found there were over 500 attacks last month, an increase of 153% compared to one year ago, and a 16% increase compared to June. Within Europe, there was a 59% increase in ransomware attacks from June to July.

Part of the significant rise is due to the ransomware group called Cl0p, whose attack on the MOVEit software has accounted for hundreds of victims this year. The Cl0p ransomware group has kept its promise to publish files on the clearweb of all its victims if contact was not made. The clearweb is simply what we know as the internet; anyone can access it. As such, there will be many organisations who are now having their sensitive data published and readily viewable for anyone who has access to the internet.

Cyber Risk in The Boardroom

The relationship between the CISO and the wider boardroom has become increasingly cooperative, with 77% of CEO’s seeing cyber as a strategic function and a potential source of competitive advantage. While it is ultimately up to the board to take steps to keep cybersecurity high on the agenda, the CISO also has a responsibility to press the message and bridge any gaps.

CISOs must deliver concerns, strategies and recommendations in a business-first manner, while avoiding jargon and overly technical language. Attracting and retaining good quality senior security professionals is very challenging in the current market and Black Arrow offer a fractional CISO service, giving access to a whole team of specialists with wider expertise, experience and backgrounds, for less than the cost of hiring one individual.

Malware-Infected Advertising Grows Ever More Sophisticated, And More Damaging

The malware exploits known as malware-infected ads, or malvertising, have been around for decades, but new reports point to a steady rise in efficacy. With malvertising, the infected ads are typically placed on legitimate ad networks, which makes them more difficult to spot and remove. The technique continues to use more and more sophisticated mechanisms for getting their infections spread throughout the web and keeping them running for a long time. The exploits can operate in one of several ways, including intercepting a user’s clickstream on random hyperlinks and substituting them with redirects to advertising websites.

Adblockers either on endpoints or at the network level can also help to prevent malvertising from causing harm.

Cyber Security is Everyone’s Responsibility

A recent survey found that 41% of respondents said that poor quality training, or a lack of training altogether, and insider threats were impacting their organisation’s security. Cyber security involves everyone as any employee can be an entry point for a cyber incident, but they also have the power to prevent one. It is important to make sure all employees are provided adequate training. Not every role requires the same training however, so it is important for organisations to identify and provide training that is appropriate to employees. Black Arrow provide live in person and online instructor lead cyber security training, both through Cyber Risk and Governance Workshops for Senior Leadership and Awareness, Behaviour and Culture Training for employees and contractors.

QR Code Hacks Are Another Thing to Worry About Now

One of the upcoming technologies thrust upon us is QR codes. At this point, you can find them at most restaurants and parking sites. You simply scan the code and you are taken to the relevant site, for example, the menu for the restaurant. Attackers have cottoned on to this and started to use QR codes in phishing attacks; the idea being that the victim will scan the code without scrutinising it and be taken to a malicious website instead.

Security Basics Aren’t So Basic Anymore

The basics of cyber security, it turns out, aren’t so basic anymore. What was considered basic has moved way beyond just having firewalls and antivirus, and the most basic controls nowadays include more advanced controls such as robust identity and access management, multi-factor authentication (MFA) and patching and vulnerability management. Many of these now basic controls are lacking or non-existent across the economy according to cyber security experts. A report found that only 28% of Microsoft users had MFA enabled as 2022 closed.

You can’t solve all the problems at once. However, progress on these fronts also relies heavily on the need for a cultural shift. Organisations need to get to the point where they view cyber security in the same light as locks on doors and seatbelts in cars.

Apple MacOS Security Myths

Apple has maintained a reputation as being more secure than other manufacturers, and whilst Apple has put many different security mechanisms into its operating system, no technology is bulletproof. Assuming an Apple device is invulnerable can lead users to believe that their Mac will not get viruses or be subject to a plethora of other cyber threats. As a result, this can lead to poor cyber hygiene from the individual, as they assume they are safe regardless of what they do. Apple users need to remain every bit as aware of risks, social engineering, keeping devices up to date, and having appropriate security controls.

Security Leaders Report Misalignment of Investments and Risk Reduction

The cyber risk landscape was analysed in a recent report that examined the amount of risk that organisations are willing to accept, their resource constraints and key priorities for approaching cyber risk in the future. The report found 66% of respondents indicating that they have limited visibility and insight into their cyber risk profiles, hindering their ability to prioritise investments and allocate resources effectively. 67% of organisations experienced a breach requiring attention within the last two years despite having traditional threat-based security measures in place. Further, 61% of security executives expressed concerns over the current misalignment between cyber security investments and their organisation's risk reduction priorities.

Many CISOs Tout SaaS (Cloud) Cyber Security Confidence, but 79% Admit to Incidents

Cyber security, IT, and business leaders alike recognise SaaS (cloud) cyber security as an increasingly important part of the cyber threat landscape. And at first glance, respondents appear generally optimistic about their SaaS cyber security as 85% answered that they are confident or very confident in their company's or customer's data security in sanctioned SaaS apps.

Despite the confidence, 79% of respondents confirmed that their organisation had identified SaaS cyber security incidents over the past 12 months. Many of those incidents occurred in environments with cyber security policies in place and enforced, as 66% of respondents claimed in their responses.

If You Ever Used Duolingo, Watch Out for Phishing Email

Users of Duolingo, past and present, should be wary of phishing emails as data on about 2.6 million accounts were scraped through an exposed application programming interface (API), and then offered on a hacking forum back in January. Login and real names, email addresses, phone numbers, and courses studied were part of the collection, which went for $1,500. Now that data has resurfaced on a different forum, and at a substantially lower cost of just a few dollars, users of the service can expect this data to be used in fresh phishing campaigns.

91% of Security and IT Professionals: Criminals are Already Using AI in Email Attacks

Recent research found that 91% of security and IT professionals are noticing cyber criminals already using AI as part of email attack campaigns, with 74% indicating they have experienced an increase in the use of AI by cyber criminals in the past six months. This is worrying as 52% reported that email security is among one of their top three concerns.

Organisations need to make sure that their technologies, procedures and policies are updated to factor in AI-enabled email attacks to help reduce the risk they pose to the organisation. Such improvements should also include employees.

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

Ransomware Group Targeting MSPs Worldwide in New Campaign

Russia-based cyber attackers called Play are evolving, with the ransomware group now using remote monitoring and management (RMM) tools at outsourced IT providers or managed service providers (MSPs) to gain access and hit downstream customers. A significant number of eventual targets are medium sized business. The group is also utilising intermittent encryption, where files are only partly encrypted, to avoid detection.

The attacks highlight the need for organisations to be aware of where they are in the supply chain and how they can be targeted through their supplier. It is not enough for an organisation to focus on its own security in isolation; organisations also need to have a way of effectively assessing their supply chain risk which includes their MSP.

Source [Dark Reading]

As Ransomware Surges, A lack of Resources Makes SMBs Most Vulnerable

Ransomware attacks continue to increase, with 1500 victims confirmed this year. It is likely this figure will continue to rise. In parallel, criminals are evolving and with that comes a rise in triple extortion; attackers are not just encrypting and exfiltrating an organisation’s data, but also using this data to blackmail employees and target third parties, hitting the supply chain.

Unfortunately for SMBs, they do not have the resources to keep up with such attacks, making them the most vulnerable. A report found that organisations that had 51 to 200 employees were the most targeted, followed by organisations with 11 to 50 employees. When it came to the types of organisations, the Financial Services sector placed first.

This should not mean SMBs should just accept this and wait to be attacked; on the contrary, their increased vulnerability means that SMBs need to effectively prioritise and allocate resources, and if necessary getting in specialist external help, to ensure their protections are the best that resources allow.

Business Email Compromise Attack Costs Far Exceeding Ransomware Losses

Cloudflare's 2023 Phishing Threats Report recorded a 17% spike in business email compromise (BEC) related financial losses between December 2021 and 2022, noting that threat actors are increasingly leaning on this attack method to target organisations. Additionally, across 2022 nearly three-quarters (71%) of respondents to the study said they experienced an attempted or successful BEC attack. The Cloudflare report found that the financial impact of BEC led to organisations suffering losses in excess of $2.7 billion, whereas ransomware caused losses of $34.3 million during the same period.

Source [ITPro]

Email Phishing Remains the Main Entry for Cyber Criminals; People with Six Personality Traits are More Susceptible

According to a report, phishing attacks were found to be the initial attack vector for nine in ten cyber attacks. The report found that the focus of a cyber criminal tended to be two objectives: achieving authenticity and getting victims to click. Worryingly, 89% of unwanted messages were found to have bypassed authentication checks, leaving people and procedures as the last line of defence in an organisation.

A separate study found that having the following traits made a user more susceptible to phishing: extroverted, agreeable, people-pleasing, quick to trust, fearful or respectful of authority, and poor self-control.

With employees playing such an important role in preventing phishing, organisations need to ensure that employees are aware of what to look for in a phishing email with regular training to account for evolving tactics. This training should be carried out by experts with experience of conducting phishing simulations, accompanied with the ability to educate users on how they can protect themselves from falling victim.

Gartner Study Finds Generative AI to be a Top Emerging Risk for Organisations

In a recent survey, Gartner found that generative AI models such as ChatGPT were the second greatest emerging risk, with concerns around data privacy. This has led to organisations looking to ban such AI, with a separate report by Blackberry finding that ChatGPT faced banning from 75% of organisations.

Banning AI in the organisation is a short-term solution. The benefits of AI are clear and its usefulness in an organisation is significant, with reports finding 75% of IT leaders in favour. Organisations should instead look at how they can govern the usage of AI in their organisation, to reduce the risk of AI-related incidents and improve the effectiveness of work.

LinkedIn Suffers Significant Wave of Account Hacks

LinkedIn users are reporting losing access to their accounts, with some being pressured into paying a ransom to get back in or else face permanent account deletion. LinkedIn is no stranger to being a target of cyber criminals; last year, the platform was deemed the most abused brand in phishing attempts likely due to its recognisability and widespread use in the corporate world. This extended as far as threat actors using fake LinkedIn profiles.

With the number of accounts being compromised, users need to be vigilant in their use of LinkedIn and be on the lookout for suspicious messages. Black Arrow recommends that users ensure they are using strong and unique passwords, combined with multi-factor authentication (MFA) to protect themselves.

Source [Dark Reading]

High Net-Worth Families are at Risk of Cyber Crime

A report found that high net-worth families have prioritised cyber security with a notable 77% of respondents stating they had a cyber security plan; however, 55% said their plan “could be better”.

A cyber security plan is not optional anymore. High net-worth families are at increased risk, with criminals cottoning on to the amount of information that is out there and the financial gain that can be made if that information is used effectively. Social media is just one of the things increasing the risk of cyber crime; unbeknownst to some families, their social media may be providing criminals a treasure trove of insight into a family’s wealth, real-time location and habits. Such information can be used by a cyber criminal to employ attacks.

Cyber Attack Rule Raises Insurance Risks for Corporate Officers

The US Securities and Exchange Commission (SEC) recently issued rules that formally outlined directors’ responsibilities in cyber security governance for the first time, laying the groundwork for potential enforcement actions. The recently issued rules bring potential regulatory probes and shareholder legal class action alleging senior executives failed to supervise their businesses’ cyber security practices.

Although the practice is not yet universal, a growing number of director and officer (D&O) policies are being drafted with cyber related exclusions. Meanwhile, most cyber insurance policies exempt SEC enforcement actions and investor claims, but some cover allegations against a company’s executives over their cyber security roles.

Whilst this is only in the US at the moment, other developed nations are likely to follow suit.

PSNI and UK Voter Breaches Show Data Security Should be Taken More Seriously

The Police Service of Northern Ireland (PSNI) and the UK Electoral Commission both suffered cyber incidents on the same day. Whilst both incidents were different in how they happened, the result was the same: sensitive information had been leaked. In the case of the PSNI, the data was leaked through a response to a freedom of information (FOI) request, in which an Excel sheet was accidentally included by the PSNI. The Electoral Commission incident resulted from a cyber attack.

The incidents are a wake-up call for organisations. If you have not already done so, you need to put things in place to help protect your data from ending up online. The PSNI incident in particular highlights the need to ensure that data does not leave the organisation by accident.

Source [The Guardian]

The Imperative of Cyber Preparedness: The Power of Tabletop Exercises

Cyber security has become an inescapable concern for organisations across industries. With cyber threats ranging from data breaches to ransomware attacks, it is paramount that companies remain vigilant and prepared.

A key way to be prepared is through a tabletop exercise that simulates a hypothetical cyber security incident and helps organisations to practice and evaluate their response. One example scenario can be responding to a ransomware attack blocking access to the organisation's computers for a ransom. These exercises serve as a practical, engaging, and low-risk way for teams to identify vulnerabilities in current plans, improve coordination, and evaluate the decision-making process during a crisis and this is something that we do with our clients on a regular basis.

Why Are Phones a Cyber Security Weak Spot?

Mobile phones are more interconnected than ever, with their usage extending to the workplace. Despite this, they often enter the corporate environment with a lack of protection and oversight. When laptops are in the corporate environment they are often secured through methods such as encryption and often the organisation has a clear oversight of the applications and activity on the laptop. Mobile phones on the other hand, are often left unmonitored, despite the fact they can and often do carry sensitive information.

Mobile phones also carry additional risks; for a start, they are easier to lose, due to their size difference and the fact they are often out more. In addition, they may have more entry points. Internet of things (IoT) devices, such as smart appliances, are often controlled by phones, making them another entry point for an attacker.

Black Arrow Cyber Advisory 18 August 2023 – Critical Citrix ADC Backdoor Campaign

Black Arrow Cyber Advisory 18 August 2023 – Critical Citrix ADC Backdoor Campaign

This is an update following the 19 July Critical Citrix ADC and Gateway flaw actively exploited advisory by Black Arrow.

This is an update following the 19 July Critical Citrix ADC and Gateway flaw actively exploited advisory by Black Arrow.

Executive Summary

Following the previous advisory on the Citrix Netscaler ADC vulnerability (CVE-2023-3519), the NCC Group has identified that as of 14 August, 1828 Citrix NetScaler servers remain compromised or ‘backdoored’ by attackers. Approximately 69% of the servers that contain a backdoor have been updated to remediate the vulnerability and are no longer vulnerable to CVE-2023-3519. This means that the affected systems were compromised by a malicious actor prior to the updates being applied, allowing the malicious actor to establish persistent access to the systems even after the vulnerability has been remediated.

What’s the risk to me or my business?

Successful exploitation of the vulnerability prior to updating would allow an attacker to perform arbitrary code execution with administrator privileges. The main attack campaign is believed to have taken place between late 20 July to early 21 July. If updates were not applied to affected and vulnerable systems prior to this date, exploitation may have already taken place.

Further information on the vulnerability can be found on our previous advisory linked below.

What can I do?

If you have not already updated to a Citrix version that resolves this vulnerability, Black Arrow recommends applying these updates urgently. All affected systems, updated and vulnerable, should be scanned for indicators of compromise (IoC), Mandiant have released a tool that can help organisations to scan their Citrix devices for evidence of post-exploitation indicators. If IoC’s are identified, then forensic data should be secured by taking a copy of both the disk and the memory of the appliance before any remediation or investigative actions are completed. If evidence of persistence such as a webshell is found, then this should be investigated through threat hunting techniques to establish the extent of the incident whilst conducting containment and remediation activities.

Black Arrow’s Perspective: The Duality of AI, Empowering Business and Cyber Attackers Alike

The Duality of AI: Empowering Business and Cyber Attackers Alike

Artificial Intelligence (AI) has unlocked countless doors to innovation, paving the way for unprecedented efficiency, automation, and business intelligence in organisations globally. However, the AI we so keenly herald as a catalyst for advancement is not without its dangers. From a cyber security perspective, the risks associated with AI, particularly those concerning insider threats and AI-driven attacks, are of increasing concern.

Artificial Intelligence (AI) has unlocked countless doors to innovation, paving the way for unprecedented efficiency, automation, and business intelligence in organisations globally. However, the AI we so keenly herald as a catalyst for advancement is not without its dangers. From a cyber security perspective, the risks associated with AI, particularly those concerning insider threats and AI-driven attacks, are of increasing concern.

Consider the potential of AI in the wrong hands

Threat actors leverage AI to enhance their illicit activities. Sophisticated cyber attacks, traditionally relegated to a small number of skilled and capable individuals or groups, could be automated and exponentially expanded in scale. The very virtues that make AI so appealing to businesses - scalability, adaptability, and autonomy - are transformed into threats by attackers to harm those same businesses as well as individuals. A cyber attacker utilising AI tools could easily automate processes like social engineering attacks, identifying system vulnerabilities, or developing advanced malware that adapts to today’s countermeasures.

AI has catapulted the capabilities of attackers

Reflect on the MOVEit scandal this summer that has impacted tens of millions of individuals globally. In May this year, the Russian-based CL0P ransomware gang exploited a previously undiscovered vulnerability in the popular file transfer platform called MOVEit. The platform is a component of the supply chain that is used by many companies, paradoxically to keep their documents secure from unauthorised access. Nonetheless, the attackers managed to break into MOVEit in different organisations to harvest the information within it, or use that access as a door to other parts of the target’s systems. So far, the compromise has claimed sensitive data from at least 230 firms across the world, from government and education to transport and finance including Ernst & Young, British Airways, the BBC and Tesco Bank. The heist undoubtedly took significant skill and expertise to accomplish, and highlights the need to manage the security within the chain of organisations and systems that are connected across borders and sectors.

Now, imagine what happens when attackers conduct these kinds of attacks by levering the power and creativity of AI. Attackers are constantly probing and identifying novel methods of attack, to swiftly bypass existing security measures and evade detection. With AI, attackers are already sending out seemingly flawless phishing messages to successfully break into systems through people, and will soon attack technology systems using AI in sophisticated ways at a rate that humans cannot possibly keep pace with.

Poisoning the AI data pool

Beyond harnessing AI for malicious intent, threat actors could exploit AI systems' inherent vulnerabilities. One alarming method is adversarial machine learning; this is a technique wherein 'poisoned' data is used to manipulate AI algorithms. In a cyber security context, attackers could intentionally feed misleading data into AI security systems, causing them to overlook genuine threats or behave unpredictably. People may be inclined to trust the output of AI making autonomous decisions, because they do not believe that malicious or false information could have been added into the source data.

AI models used in sensitive sectors like healthcare, finance, or defence are an attractive target for intellectual property theft. The very algorithms that drive insights, predictions, and automated decisions could be stolen, reverse-engineered, or used maliciously. The successful theft of an AI model could cause extensive financial loss, and potentially even endanger national security.

Insider threats

The realm of insider threats is yet another frontier where AI's risk factors come to the fore. Consider the rise of powerful language models like ChatGPT, that must be handled with care in organisations because sometimes, employees unwittingly become a threat.

Samsung reported that their staff had leaked sensitive proprietary information by inputting it into such models. Many organisations such as Amazon and Apple have already banned their employees from using publicly accessible generative AI systems like ChatGPT, and have instead provided their own private alternatives for internal use.

How to protect your organisation

Mitigating the dangers of AI requires a two-pronged approach. First, robust AI governance is needed at a national and international level. Governments must implement ethical guidelines, transparency measures, and regulation; however, these measures are unlikely to be implemented at a pace that matches the development and adoption of AI. Secondly, organisations must themselves immediately begin to foster a culture of AI and cyber security awareness among their employees. Clear communication about the capabilities and potential dangers of AI, coupled with training employees to recognise AI-enhanced threats and implementing strong cyber security controls across people, operations and technology can all help in this endeavour.

The advent of AI has ushered in a new era of previously unimaginable benefits, and risks. From AI-driven cyber attacks to the dangers posed by employee use, the threats are real and rapidly evolving. As organisations increasingly and inevitably adopt AI, they must stay vigilant to these threats and proactively invest in robust cyber security measures to safeguard against them. The reality of AI and cyber security is a delicate balancing act that we are all learning as we leverage those benefits while mitigating the risks.

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

75% of Organisations Worldwide Set to Ban ChatGPT and Generative AI Apps on Work Devices

Newly released research found that 75% of organisations worldwide are currently implementing or considering bans on ChatGPT and other generative Artificial Intelligence (AI) applications within the workplace, with 61% stating that it will be a long term or permanent solution. Despite this, the majority recognised the opportunity such applications bring to the workplace, with 55% believing it would increase efficiency. All in all, 81% remained in favour of AI, highlighting that whilst organisations see the benefit, they are not ready to take the plunge for fear of being caught flat-footed.

Many organisations may simply not have the expertise-in house or confidence to employ AI effectively. These organisations lack an effective AI management plan, which governs the usage of AI in the corporate environment, rather than banning it outright. By having a clear-set AI plan, organisations can use AI to improve their efficiency, whilst maintaining cyber resilience. An increasing number of organisations have approached us at Black Arrow to discuss how to embrace AI securely; contact us to see how we can help you.

How an Eight-Character Password Could be Cracked in Just a Few Minutes

Strong and complex passwords are necessary to protect online accounts and data from cyber criminals. Complex passwords typically use lowercase and uppercase characters, numbers, and special characters. But complexity by itself can still open your password to cracking if it doesn’t contain enough characters, according to research by security firm Hive Systems. The report found that a complex password of eight characters can be cracked in only five minutes, and other weaker or shorter passwords are cracked instantly. However, passwords that have a greater number of characters are less vulnerable: for example an 18 character password, even if only lowercase letters, would take 481,000 years for a computer to crack.

Since creating and remembering multiple complex and lengthy passwords on your own is impossible, a password manager is your best bet. By using a password manager for yourself or within your organisation, you can generate, store and apply strong passwords for websites and online accounts.

Ransomware Victims Surge 143% as Threat Actors Pivot to Zero-Day Exploits

The number of organisations that became victims of ransomware attacks surged 143% between the first quarter of 2022 and first quarter of this year, as attackers increasingly leveraged zero-day vulnerabilities to break into target networks.

In many of these attacks, threat actors did not bother to encrypt data belonging to victim organisations. Instead, they focused solely on stealing their sensitive data and extorting victims by threatening to sell or leak the data to others. The tactic left even those with otherwise robust backup and restoration processes backed into a corner; this highlights the need for organisations to be able to detect and ideally block anomalous exfiltration of data, and have effective and rehearsed incident response plans to address the concept of pure exfiltration, because having backups is not enough.

The costs of these types of controls continue to fall making them viable for even smaller businesses. Without tools like Managed Detection and Response (MDR) and Data Loss Prevention (DLP), attacks of this nature cannot be detected until it is too late to do anything to stop them.

How Executives’ Personal Devices Threaten Business Security

Individuals, including executives, are considered a major target for cyber attacks. Motivated attackers know the right individual people they want to go after to achieve their larger organisational goal, and they’ll use any means necessary to be successful.

A recent report found that most executives are using their personal devices for work, creating a “backdoor” for cyber criminals to access large organisations. 50% of executive respondents reported receiving work-related scams in their personal emails.

Personal device use can be effective for organisations, however they need to implement an effective bring-your-own-device (BYOD) procedure and provide employees, including executives, with frequent user awareness and education training. All users at all levels within an organisation need to understand the risks, and importantly the role they play in keeping the organisation secure.

77% of Financial Firms Saw an Increase in Cyber Attack Frequency

According a recent report on the financial services sector, 77% of firms reported an increase in attack frequency, and 87% said attacks were more severe. These firms unanimously said they would look to outsource their cyber security programs to third-party providers to shore up their cyber defences. Among the respondents, firms need to protect hybrid work environments (62%), consolidate cyber security and managed IT services (41%) and tap industry-specific and regulatory expertise (33%).

Protecting Against Sophisticated Cyber Attacks Requires Layered Defences

Faced with an influx of sophisticated cyber threats, including usage of AI to further enhance the efficacy of social engineering attacks, and the growth of both malware-as-a-service (MaaS) and ransomware-as-a-service (RaaS), it is critical for organisations to invest in layered security defences.

Services like managed detection and response (MDR) are integral to monitoring, investigating and responding to threats in real time. But without a strong and comprehensive foundational cyber security posture, managed services alone cannot effectively mitigate threats. To ensure comprehensive defences against emerging threats, organisations must prioritise proactive measures that can stop attacks before they even start. As adversaries continue to refine their attack techniques, layered protection that covers every stage in the attack chain becomes imperative.

Managing Human Cyber Risks Matters Now More Than Ever

As artificial intelligence (AI) amplifies the sophistication and reach of phishing, vishing, and smishing attacks, understanding and managing human cyber risks has become increasingly vital, according to the SANS Institute. It makes sense as no matter the technological advancement, the human element has always been a point of entry for attackers.

A recent study found that mature security programs, marked by robust teams and leadership support, are characterised by having at least three full-time employees in their security awareness teams. In some cases, this isn’t feasible for an organisation and this is where outsourcing comes in. By outsourcing security awareness, organisations can ensure that they have access to security awareness experts, to keep their organisation educated. Here at Black Arrow we offer regular security and awareness training, bespoke to your organisation, for your employees and leadership team.

Hackers are Targeting Top Executives’ Microsoft 365 Accounts to Steal Work Logins

Cyber security provider Proofpoint reported that high-level execs at some of the world’s leading companies are repeatedly targeted with credential-stealing attacks. More alarmingly, according to Proofpoint, around one-third (35%) of the compromised users had multi-factor authentication (MFA) enabled.

The attacks come amid a rise in cases of EvilProxy, a phishing tool that allows attackers to steal even MFA-protected credentials. In the three months to June 2023, around 120,000 EvilProxy phishing emails were observed being sent to hundreds of targeted organisations globally, with many targeting Microsoft 365 user accounts in particular. Approximately 39% of the victims were C-level executives of which 17% were Chief Financial Officers, and 9% were Presidents and CEOs. Users must be trained effectively, to help mitigate the chance of them suffering a phishing attack. The C-suite is no exception.

UK Shaken by Major Data Breaches

Recent major data breaches impacting crucial institutions like the UK Electoral Commission (which exposed the data of 40 million UK voters) and the Police Service of Northern Ireland, have brought attention to potential risks. Following a recent freedom of information request 10,000 police officers and staff details where published including details such as first name and surname, their rank or grade and the unit and where they are based. This breach occurred when a junior member of staff forgot to remove the master spreadsheet containing sensitive data when responding to the request.

Threat of Cyber Attacks to UK National Security Upgraded: Compared to Chemical Weapons or Nuclear Attack

The UK government has raised the threat level posed by cyber attacks, now deeming the risk of cyber attacks to be more severe than that presented by small-scale chemical, biological, radiological, or nuclear (CBRN) attacks according to the latest National Risk Register (NRR) report for 2023. The report also highlighted artificial intelligence (AI) as a “chronic risk” – that is, one that poses “continuous challenges that erode our economy, community, way of life, and/or national security”.

Mac Users are Facing More Dangerous Security Threats Than Ever Before

Apple’s MacBook Pro or iPhone devices are often perceived as safer, from a cyber security standpoint, compared to those from Microsoft or Google, mostly because of its “walled garden” approach. However, another key reason why hackers were not historically as interested in Apple was the smaller market share Apple held. That is no longer the case and as attacks are rising against Apple devices, this is something we expect to see continuing to accelerate.

In the last 10 years, Apple’s market share on desktop has increased from less than 7.5% to just over 20% today. Apple frequently patches actively exploited vulnerabilities, with overall 261 security vulnerabilities addressed so far this year. A recent report found that Mac users are targeted by three key threats: Trojans, Adware, and Potentially Unwanted Applications (PUA). Of the three, Trojans are the biggest single threat, making up more than half of all threat detections. Of all those detections, around half (52.7%) were for the EvilQuest encryption malicious software.

Cyber Attack to Cost Outsourcing Firm Capita up to £25m

Capita expects to take a financial hit of as much as £25m as a result of a cyber attack that began in March, pushing the outsourcing group to a pre-tax loss of almost £68m for the first half of the year. The group is still recovering from the attack by the Black Basta ransomware group, which hacked its Microsoft Office 365 software and accessed the personal data of staff working for the company and dozens of clients. Capita, which runs crucial services for local councils, the military, and the NHS, estimated that the financial costs associated with what it called the “cyber incident” would be between £20m and £25m. Previous estimates had put the cost at £15m to £20m.

The group said this new figure reflected the complexities of analysing the “exfiltrated” data, as well as costs of recovery and remediation and new investment to improve its cyber security. However, Capita said it was not currently able to estimate the level of any potential fine related to the incident and had not yet made any provision to cover any future costs. The company’s shares fell by more than 12% in morning trading on Friday after the release of its results, making it the biggest faller on the FTSE 250.

Government and Public Services Face 40% More Cyber Attacks and Struggle to Protect Due to Lack of Resources

A report published by BlackBerry noted a 40% rise in cyber attacks against public sector organisations and government institutions. One of the reasons is the limited resources and resistance that these government and public have; this makes it much easier for an attacker. An easy target is an attractive target.

Welcome to this week’s Black Arrow Cyber Threat Intelligence 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

Top 12 Exploited Vulnerabilities List Highlights Troubling Reality That Many Organisations Are Still Not Patching

A joint advisory from US and allied cyber security agencies highlights the top routinely exploited vulnerabilities. This is a list that includes old and well-known bugs that many organisations still have not patched, including some vulnerabilities that have been known for more than five years. The list underscores how exploiting years-old vulnerabilities in unpatched systems continues to dominate the threat landscape. Organisations are more likely to be compromised by a bug found in 2021 or 2020 than they are by ones discovered over the past year.

This report emphasises that a vulnerability management strategy relying solely on CVSS for vulnerability prioritisation is proving to be insufficient at best; CVSS is an established method for assigning criticality scores to known vulnerabilities based on different scoring criteria. Additional context is required to allow for a more scalable and effective prioritisation strategy. This context should stem from internal sources, for example, the target environment (asset criticality, mitigating controls, reachability), as well as from external sources, which will permit a better assessment of the likelihood and feasibility of exploitation. Most organisations have a limited patching capacity, affected by the tooling, processes, and skills at their disposal. The challenge is to direct that limited patching capacity towards vulnerabilities that matter most in terms of risk reduction. Therefore, the task of sifting the signal through the noise is becoming increasingly more important.

67% of Data Breaches Start with a Single Click, with 1 in 100 Emails Being Malicious

In a report that leveraged data from 23.5 billion cyber security attacks, spanning 500 threat types and 900 distinct infrastructure and software vulnerabilities it was found that approximately 67% of all breaches start with someone clicking on a seemingly safe link, which explains why adversaries begin 80-95% of all attacks with a phishing email.

A separate report found that there was a 36% rise in cyber attacks in the first half of 2023. Email continued to be the main vector for delivering malicious content, with as many as 1 in every 100 emails sent in the first half of 2023 found to be malicious. In addition, malware accounted for 20% of attacks, and business email compromise (BEC) constituted 8%.

The findings reinforce the need for organisations to employ effective and regular security awareness training for users to better help them to not only identify, but also report such attacks to help strengthen the cyber resilience of the organisation. Black Arrow offers bespoke training to all roles within the organisation as well as upskilling tailored to those at the board level.

Ransomware Attacks Hit All Time High. Attackers’ Motives Change, So Should Your Defence

Cases of straight-up data theft and extortion now appear to be more widespread a threat than ransomware, becoming the single most observed threat in the second calendar quarter of 2023, according to new data released by researchers. 1,378 organisations have been named as victims on ransomware data-leak websites in Q2 2023. This was a 64.4% increase from the record-breaking number of victims named in Q1 2023.

Despite both the rise in threats and the high percentage of respondents whose organisations suffered recent attacks, there hasn’t been a corresponding uptick in strategic measures to shore up cyber resilience. In fact, close to four in five survey respondents don’t have complete confidence that their company has a cyber resilience strategy designed to address today’s escalating cyber challenges and threats.

The Generative AI War Between Companies and Hackers is Starting

To no one’s surprise, criminals are tapping open-source generative AI programs for all kinds of heinous acts, including developing malware and phishing attacks, according to the FBI. This comes as the UK National Risk Register officially classes AI as a long-term security threat. It’s safe to say AI is certainly a controversial field right now, with the battle between companies and hackers really starting to take place; only recently had technology giants such as Amazon, Google, Meta and Microsoft met with the US President Joe Biden to pledge to follow safeguards.

A recent report from security firm Barracuda has found that between August 2022 and July 2023, ransomware attacks had doubled and this surge has largely been driven by the breaching of networks via AI-crafted phishing campaigns, as well as automating attacks to increase reach, again using AI.

Despite the controversy, AI can be of tremendous value to organisations, helping to streamline and automate tasks. Organisations employing or looking to employ AI in the workplace should also have effective governance and identification procedures over the usage of said AI. Equally, when it comes to defending against AI attacks, organisations need to have a clear picture of their attack landscape, with layers of defence.

Spend to Save: The CFO’s Guide to Cyber Security Investment

As a CFO, you need to make smart choices about cyber security investments. The increasing impact of data breaches creates a paradox: While more spending is necessary to combat these challenges, this spending isn’t directly tied to profit. Instead, cyber security spending should be seen an investment in the future of your business.

The impact of a cyber event extends beyond quantifiable currency loss. Further impacts include those of reputation and customer retention. CFOs should look to identify weak spots, understand the effect these can have, pick the right solution that mitigates these and finally, advocate cyber security and robust governance at the board level.

It is important to remember, cyber security is not just a technical issue, but also a business one, and you have a key role in ensuring the security and resilience of your organisation.

Corporate Boards Take Heed: Give CISOs the Cold Shoulder at your Peril

The debate over whether the CISO should, by the very nature of the position, be considered a member of the C-suite has been raging for some time and seems likely to continue for a good while to come. CISOs should not only have a seat among the uppermost echelon at the big table but also be recognised as a foundational element in the success of any business.

There is a danger that, without an effective CISO, organisations can end up in a perilous situation in which there's no one driving the cyber security bus at a time when vulnerabilities and incidents are ever on the rise. When the CISO has a seat at the big table, everybody wins.

How the Talent Shortage Impacts Cyber Security Leadership

The lack of a skilled cyber security workforce hampers the effectiveness of an organisation’s security program. While technologies like AI and machine learning can provide some support, they are not sufficient, especially for small and medium sized businesses (SMBs). The cyber security workforce shortage affects not just current security but the future of leadership roles, including CISOs and CSOs.

Today’s CISOs require a blend of technology and business understanding. According to the (ISC)2 2022 Workforce Study, the global cyber security workforce is nearly 5 million and growing at 26% yearly. However, more than 3 million jobs still need to be filled, including specialised roles in cloud security, data protection, and incident response. This gap jeopardises functions like risk assessment, oversight, and systems patching.

The greatest talent shortage is found in soft skills, leading to a trend of looking outside the traditional security talent pool. The future of CISOs will likely require a solid security background, but as the talent gap widens, finding leadership candidates from the existing pool may remain challenging.

Salesforce, Meta Suffer Phishing Campaign that Evades Typical Detection Methods

A recent report by cyber security company identified a sophisticated email phishing campaign exploiting a zero-day vulnerability in Salesforce's legitimate email services. The vulnerability allowed threat actors to craft targeted phishing emails, cleverly evading conventional detection methods by leveraging Salesforce's domain and reputation and exploiting legacy quirks in Facebook's web games platform.

Whilst Facebook and Salesforce have now addressed the issue, it goes to show that technology alone is not enough to stop phishing; operational and people controls are still necessary and should form part of an effective organisational response.

Cyber Insurance and the Ransomware Challenge

The cyber insurance industry has been heavily criticised for providing coverage for ransom payments. A frequent accusation, which has become close to perceived wisdom in policymaking and cyber security discussions on ransomware, is that cyber insurance has incentivised victims to pay a ransom following a cyber incident, rather than seek alternative remediation options. However, the insurance industry could do much more to instil discipline in both insureds and the ransomware response ecosystem in relation to ransom payments to reduce cyber criminals’ profits. Insurers’ role as convenors of incident response services gives them considerable power to reward firms that drive best practices and only guide victims towards payment as a last resort.

While the insurance industry has the power to do this, there are still challenges that need to be addressed in the underwriting process. Offering expensive policies that exclude common risks such as ransomware or nation-state attacks is simply not a sustainable approach. This has helped insurers become more profitable for now, but these are only short-term fixes to the real problem at hand. Namely, that the underwriting process for cyber insurance policies is still not that sophisticated. Most underwriters are poorly equipped to effectively measure the cyber risk exposure of new or renewing customers.

Microsoft Exposes Russian Hackers' Sneaky Phishing Tactics via Microsoft Teams Chats

Microsoft on Wednesday disclosed that it identified a set of highly targeted social engineering attacks mounted by a Russian nation-state threat actor using credential theft phishing lures sent as Microsoft Teams chats. The tech giant attributed the attacks to a group it tracks as Midnight Blizzard.

"In this latest activity, the threat actor uses previously compromised Microsoft 365 tenants owned by small businesses to create new domains that appear as technical support entities" Microsoft said. "Using these domains from compromised tenants, Midnight Blizzard leverages Teams messages to send lures that attempt to steal credentials from a targeted organisation by engaging a user and eliciting approval of multi-factor authentication (MFA) prompts."

66% of Cyber security Leaders Don’t Trust Their Current Cyber Risk Mitigation Strategies

A recent report found that 66% of cyber security leaders don’t trust their current cyber risk mitigation strategies. It was also found that while 90% of respondents say their organisation has dedicated resources responsible for managing and reducing cyber risk, in almost half of situations (46%) this consists of just one person.

In some cases, it can be hard to get the necessary talent to build out the cyber security arm of an organisation; this is where organisations can look towards outsourcing to fulfil positions with expertise. At Black Arrow we offer many services to help you to govern your cyber security, including as virtual CISO that leverages our diverse team with backgrounds from British intelligence, board governance, IT and finance.

UK legal Sector at Risk, National Cyber Security Centre Warns

Over the past three years more than 200 ransomware attacks worldwide have been inflicted on companies in the legal industry. The UK was the second most-attacked country constituting 2.3% of all ransomware attacks across various sectors. The legal sector was the fourth most-attacked industry in the UK in 2022. Ransomware groups are indiscriminate in their targeting, attacking companies of all sizes, from small law firms with only ten employees to large firms with 1,000+ employees, and ranging in revenue from companies generating £100 million to those with under £3 million. No single kind of company is immune to these attacks.

The International Bar Association (IBA) has released a report to guide senior executives and boards in protecting their organisations from cyber risk. Entitled "Global perspectives on protecting against cyber risks: best governance practices for senior executives and boards of directors," the report aims to provide leaders with insight into the primary elements of a robust cyber risk management programme. Its recommendations for senior executives and boards encompass understanding the organisation's cyber risk profile, knowing what information assets to safeguard, being aware of significant regulatory requirements, and recognising the security standards utilised by the organisation.

Startups Should Move Fast and Remember Cyber Security

The importance of cyber security for startups, which can often be overlooked in the pursuit of fast-paced growth, cannot be overstated. However, cyber attacks can have devastating consequences for businesses of all sizes. The percentage of micro-businesses in the UK that consider cyber security a high priority has dropped from 80% to 68% in the past year, possibly due to wider economic pressures. Cyber criminals target businesses of all sizes, often initially using automated software to find weak spots. Startups can be particularly vulnerable due to their fast-paced environments and new or less familiar supply chains. The use of shared office spaces can also increase risk.

The UK DCMS/DSIT 2023 Cyber Security Breaches survey reported that almost a third of businesses (32%) and a quarter of charities (24%) reported breaches or attacks in the past 12 months alone, with the average victim losing £15,300. Startups have the unique advantage of being able to implement cyber security best practices from the outset and embed them into company culture. It is recommended that startups prioritise cyber security from the get-go to protect their business and ensure long-term growth.

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

  • Half of UK Businesses Struggle to Fill Cyber Security Skills Gap

Half of UK businesses have a cyber security skills gap that they are struggling to fill amid a challenging labour market, according to data published by the UK Department for Science, Innovation and Technology (DSIT), which found that there were more than 160,000 cyber security job postings in the last year – a 30% increase on the previous period. In all, the UK requires an additional 11,200 people with suitable cyber skills to meet the demands of the market, the report estimates.

In a separate report, it was found that a lack of executive understanding and an ever-widening talent gap is placing an unsustainable burden on security teams to prevent business-ending breaches. When asked how long it takes to fill a cyber security role, 82% of organisations report it takes three months or longer, with 34% reporting it takes seven months or more. These challenges have led one-third (33%) of organisations to believe they will never have a fully-staffed security team with the proper skills.

With such a gap, some organisations have turned to outsourcing cyber security roles, such as chief information security officers (CISOs), leading to a rise in virtual CISOs (vCISO). With outsourcing, organisations can ensure that they are easily able to pick up and use cyber security experts, greatly reducing the delay were they to hire. Black Arrow supports clients as their vCISO with specialist experience in cyber security risk management in a business context.

  • Deloitte Joins Fellow Big Four MOVEit victims PWC, EY as Victims Exceed 500

The global auditing and accounting firm Deloitte appeared alongside a further 55 MOVEit victims that were recently named by the Cl0p ransomware gang, making them the third Big Four accounting firm to be affected and amongst over 500 organisations in total with that number expected to continue to increase.

Research by Kroll has also uncovered a new exfiltration method used by Cl0p in their the MOVEit attacks, highlighting constant efforts by the ransomware gang. Worryingly, it has been reported that Cl0p have made between $75-100 million from ransom payments and it is expected this, along with the victim count, will rise.

  • Why Cyber Security Should Be Part of Your ESG Strategy

Organisations need to consider cyber security risks in their overall environmental, social and governance (ESG) strategy amid growing cyber threats and regulatory scrutiny. The ESG programme is, in many ways, a form of risk management to mitigate the risks to businesses, societies and the environment, all of which can be impacted by cyber security. The investment community has been singling out cyber security as one of the major risks that ESG programmes will need to address due to the potential financial losses, reputational damage and business continuity risks posed by a growing number of cyber attacks and data breaches.

Various ESG reporting frameworks have emerged in recent years to provide organisations with guidelines on how they can operate ethically and sustainably, along with metrics that they can use to measure their progress. There are also specific IT security standards and frameworks, including ISO 27001 and government guidelines. Some regulators have gone as far as mandating the adoption of baseline security standards by critical infrastructure operators and firms in industries like financial services, but that does not mean organisations outside of regulated sectors are less pressured to shore up their cyber security posture.

  • Lawyers Take Frontline Role in Business Response to Cyber Attacks

Cyber security risk has shot to the top of general counsels’ agendas as the sophistication and frequency of attacks has grown. According to security company Sophos’s State of Ransomware 2023 report, 44% of UK businesses surveyed said they had been hit with ransomware in the past year. Of those affected, 33% said their data was encrypted and stolen and a further 6% said that their data was not encrypted but they experienced extortion.

In-house lawyers have a key role around the boardroom table when dealing with a breach including war-gaming and discussing cases in which a company will pay a ransom. The advent of General Data Protection Regulation (GDPR) legislation in Europe, and equivalents elsewhere, demands that businesses hit by a data breach notify a regulator, and the individuals whose data was stolen, or both, depending on certain factors. This has led to far greater exposure of cyber incidents which companies previously could have tried to deal with privately.

  • Organisations Face Record $4.5M Per Data Breach Incident

In a recent report conducted by IBM, the average cost per data breach for US business in 2023 jumped to $4.45 million, a 15% increase over three years. In the UK, the average cost was found to be £3.4 million, rising to £5.3 million for financial services. It is likely that the cost per breach will maintain a continual rise, with organisations struggling to crack down on cyber crime, something threat groups like Cl0p are taking advantage of.

https://uk.newsroom.ibm.com/24-07-2023-IBM-Security-Report-Cost-of-a-Data-Breach-for-UK-Businesses-Averages-3-4m

  • Cryptojacking Soars as Cyber Attacks Diversify

According to a recent report, a variety of attacks have increased globally, including cryptojacking (399%), IoT malware (37%) and encrypted threats (22%). This reflects the increase in actors who are changing their methods of attacks. The report found that we can expect more state-sponsored activity targeting a broader set of victims in 2023, including SMBs, government entities and enterprises.

Cryptojacking, sometimes referred to as malicious cryptomining, is where an attacker will use a victim’s device to mine cryptocurrency, giving the attacker free money at the expense of your device, network health and electricity.

https://www.helpnetsecurity.com/2023/07/27/cryptojacking-attacks-rise/

  • Ransomware Attacks Skyrocket in 2023

Ransomware attacks surged by 74% in Q2 2023 compared to the first three months of the year, a new report has found. The significant increase in ransomware over April, May and June 2023 suggests that attackers are regrouping. In July 2023, the blockchain analysis firm Chainalysis found that in the first half of 2023, ransomware attackers extorted $176m more than the same period in 2022, reversing a brief downward trend in 2022.

The report also observed an uptick in “pure extortion attacks,” with cyber criminals increasingly relying on the threat of data leaks rather than encrypting data to extort victims. Such schemes may not trigger any ransomware detection capability but could potentially be picked up by a robust Data Loss Prevention (DLP) solution.

https://www.infosecurity-magazine.com/news/ransomware-attacks-skyrocket-q2/

  • Blocking Access to ChatGPT is a Short-Term Solution to Mitigate AI Risk

Despite the mass adoption of generative AI, most companies don’t know how to assess its security, exposing them to risks and disadvantages if they don’t change their approach. A report found that for every 10,000 enterprise users, an enterprise organisation is experiencing approximately 183 incidents of sensitive data being posted to ChatGPT per month. Worryingly, despite the security issues, only 45% have an enterprise-wide strategy to ensure a secure, aligned deployment of AI across the entire organisation.

Blocking access to AI related content and AI applications is a short term solution to mitigate risk, but comes at the expense of the potential benefits that AI apps offer to supplement corporate innovation and employee productivity. The data shows that in financial services and healthcare nearly 1 in 5 organisations have implemented a blanket ban on employee use of ChatGPT, while in the technology sector, only 1 in 20 organisations have done likewise.

  • Protect Your Data Like Your Reputation Depends on It (Because it Does)

Data breaches can be incredibly costly. Be it lawsuits, regulatory fines, or a fall in stock price, the financial consequences of a breach can bring even the largest organisation to its knees. However, in the face of economic damage, it’s too easy to overlook the vast reputational impacts that often do more harm to a business. After all, it’s relatively easy to recoup monetary losses, less so to regain customer trust.

It’s important to remember that reputational damage isn’t limited to consumer perceptions. Stakeholder, shareholder, and potential buyer perception is also something that needs to be considered. By having effective defence in depth controls including robust data loss prevention (DLP) solutions in place, organisations can reduce the risk of a breach from happening.

https://informationsecuritybuzz.com/protect-your-data-like-your-reputation-depends-on-it-because-it-does/

  • Why CISOs Should Get Involved with Cyber Insurance Negotiation

Generally negotiating cyber insurance policies falls to the general counsel, chief financial officer, or chief operations officer. Having the chief information security officer (CISO) at the table when negotiating with insurance brokers or carriers is a best practice for ensuring the insurers understand not only which security controls are in place, but why the controls are configured the way they are and the organisation's strategy. That said, often best practices are ignored for reasons of expediency and lack of acceptance by other C-suite executives.

Sometimes being the CISO can be a no-win position. According to a recent survey more than half of all CISOs report to a technical corporate officer rather than the business side of the organisation. This lack of recognition by the board can diminish the CISO's ability to deliver business-imperative insights and recommendations, leaving operations to have a more commanding influence on the board than cyber security. Too often the CISO gets the responsibility to protect the company without the authority and budget to accomplish their task.

https://www.darkreading.com/edge-articles/why-cisos-should-get-involved-with-cyber-insurance-negotiation

  • Companies Must Have Corporate Cyber Security Experts, SEC Says

A recent report has found that only five Fortune 100 companies currently list a security professional in the executive leadership pages of their websites. This is largely unchanged from five of the Fortune 100 in 2018. One likely reason why a great many companies still don’t include their security leaders within their highest echelons is that these employees do not report directly to the company’s CEO, board of directors, or chief risk officer.

The chief security officer (CSO) or chief information security officer (CISO) position traditionally has reported to an executive in a technical role, such as the chief technology officer (CTO) or chief information officer (CIO). But workforce experts say placing the CISO/CSO on unequal footing with the organisation’s top leaders makes it more likely that cyber security and risk concerns will take a backseat to initiatives designed to increase productivity and generally grow the business.

The US Securities and Exchange Commission (SEC) has recently implemented new regulations necessitating publicly traded companies to report cyber attacks within four business days, once they're deemed material incidents. While the SEC is not presently advocating for the need to validate a board cyber security expert's credentials, it continues to insist that cyber security expertise within management be duly reported to them. The increased disclosure should help companies compare practices and may spur improvements in cyber defences, but meeting the new disclosure standards could be a bigger challenge for smaller companies with limited resources.

https://krebsonsecurity.com/2023/07/few-fortune-100-firms-list-security-pros-in-their-executive-ranks/

  • Over 400,000 Corporate Credentials Stolen by Info-stealing Malware

Information stealers are malware that steal data stored in applications such as web browsers, email clients, instant messengers, cryptocurrency wallets, file transfer protocol (FTP) clients, and gaming services. The stolen information is packaged into archives called 'logs,' which are then uploaded back to the threat actor for use in attacks or sold on cyber crime marketplaces. Worryingly, employees use personal devices for work or access personal stuff from work computers, and this may result in many info-stealer infections stealing business credentials and authentication cookies. A report has found there are over 400,000 corporate credentials stolen, from applications such as Salesforce, Google Cloud and AWS. Additionally, there was a significant increase in the number containing OpenAI credentials; this is alarming as where AI is used without governance, the credentials may leak things such as internal business strategies and source code.

With such an array of valuable information for an attacker, it is no wonder incidents involving info stealers doubled in Q1 2023. Organisations can best protect themselves by utilising password managers, enforcing multi-factor authentication and having strict usage controls. Additionally, user awareness training can help avoid common infection channels such as malicious websites and adverts.

Black Arrow Cyber Advisory 25 July 2023 – ‘Zenbleed’ Vulnerability Affecting AMD Zen2 Processors

Black Arrow Cyber Advisory 25 July 2023 – ‘Zenbleed’ Vulnerability Affecting AMD Zen2 Processors

Executive Summary

A vulnerability dubbed as ‘Zenbleed’ was discovered in AMD's Zen2 microarchitecture which could enable an malicious attacker to steal sensitive data, such as passwords and encryption keys. The Zenbleed vulnerability has been found to affect all AMD Zen 2 processors, including various models of the Ryzen processor and EPYC processor series.  Zenbleed requires local account access to the target system and a high degree of specialization and knowledge to exploit, however a proof of concept has now been publicly released.

What’s the risk to me or my business?

Exploitation of this vulnerability could compromise the confidentiality of data held or accessed through an affected device, allowing an attacker to gain unauthorised access to sensitive data. In addition, detection of the exploitation has been reported as almost impossible due to there being no requirement for elevated privileges to perform the attack. This vulnerability could also allow a malicious actor on a shared tenancy environment to access information running on the same server from a different tenant.

What can I do?

This vulnerability affects all Zen 2 class processors and as such it is essential to prioritise the patching of the upcoming updates to protect devices from this vulnerability when they become available. AMD has released a security bulletin detailing the AGESA Firmware updates which will be included within the BIOS updates for affected processors, and have classified the vulnerability as ‘Medium’ severity. Microcode updates have been created for the affected AMD EPYC processors, however updates for the Desktop, Mobile, High-end Desktop and Workstation processors are scheduled for later in the year. Once OEM’s have released BIOS updates it is strongly recommended that they are applied after appropriate testing has taken place.

In the meantime, a workaround has been recommended by the security researcher who discovered the vulnerability. If you are unsure whether you are impacted or how to implement the mitigation, then you should contact your vendor/MSP. Please note, workarounds are not a permanent fix and Black Arrow maintains that the patches should be applied when available.

Technical Summary

CVE-2023-20593 – If successfully exploited this vulnerability allows a malicious actor to access sensitive data from any system operation including those taking place in virtual machines, isolated containers, and sandboxes.

Affected product ranges include:

  • 2nd Generation AMD EPYC “Rome” Processors

  • AMD Ryzen 3000 and 4000 series Desktop Processors

  • AMD Ryzen Threadripper 3000 and 3000WX series High End Desktop and Workstation Processors

  • AMD Ryzen 4000, 5000 and 7020 series Mobile Processors

Further details of the Zenbleed vulnerability can be found here:

Black Arrow Cyber Advisory 25 July 2023 – Newly Exploited Apple-Zero Day Addressed, Patch Now

Black Arrow Cyber Advisory 25 July 2023 – Newly Exploited Apple-Zero Day Addressed, Patch Now

Executive Summary

Apple has recently released multiple patches, covering a number of vulnerabilities, including one actively exploited zero-day. The zero-day vulnerability has been found to affect devices running vulnerable versions of iOS, iPadOS, macOS, tvOS, watchOS and Safari. The actively exploited zero-day allows threat actors to obtain the highest privileges available (kernel privileges) on affected devices. Earlier this month, another actively exploited zero day, CVE-2023-37450, was addressed by Apple through a Rapid Security Response update.

What’s the risk to me or my business?

Exploitation of the vulnerability could allow an attacker unauthorised access to sensitive data, allowing them to manipulate or delete important information, or even take over the entire device, compromising the confidentiality, integrity, and availability of the data held by an exploited device. In some cases, threat actors are exploiting the vulnerability to install spyware on vulnerable devices.

What can I do?

Given the widespread use of Apple devices for both corporate and personal use, it is important to prioritise the application of the released patches to protect devices. Apple has also released patches addressing these vulnerabilities for products that are no longer supported. We recommend updating your devices promptly to these latest versions. Apple has acknowledged active exploitation of these vulnerabilities and as such recommends updating immediately. Organisations who do not use Apple devices, but have a bring your own device policy should consider whether this may include Apple devices.

Apple have addressed the zero-day in the following versions:

  • macOS Ventura 13.5

  • iOS 16.6

  • iPadOS 16.6

  • Safari 16.6

  • tvOS 16.6

  • watchOS 9.6

 Technical Summary

CVE-2023-38606 Successful exploitation of this flaw could lead to a threat actor obtaining kernel privileges (the highest available). This allows the malicious actor to “modify sensitive kernel state”.

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 Attacks Reach Two-Year High Amid Ransomware Resurgence as Financial Service Firms Lose $32 Billion in 5 Years

The average weekly volume of cyber attacks reached a two-year high in the second quarter of 2023 amid a spike in activity among ransomware groups according to Check Point Research, with healthcare in particular facing a significant year-on-year increase. The impact of ransomware hits every organisation, with separate research finding global financial services organisations having lost over $32bn in downtime since 2018 due to ransomware breaches.

A recent report found that the ransomware gangs LockBit and Cl0p alone accounted for nearly 40% of all recorded ransomware attacks across June 2023. The impact from Cl0p’s MOVEit attack alone has been felt by over 400 organisations since May 2023. One of the key takeaways from the MOVEit attack is that no matter the sector, any organisation can be a victim and as such it is essential to have effective controls in place, incorporating defence-in-depth. It’s worth considering how many organisations are still running vulnerable instances of MOVEit, or have someone in their supply chain who is.

https://www.itpro.com/security/ransomware/weekly-cyber-attacks-reach-two-year-high-amid-ransomware-resurgence

  • MOVEit Body Count Closes in on 400 Organisations, 20M+ Individuals

The number of victims and the costs tied to the MOVEit file transfer hack continues to climb as the fallout from the massive supply chain attack enters week seven. In late May 2023, Russian ransomware gang Cl0p exploited a security hole in Progress Software's MOVEit product suite to steal documents from vulnerable networks. As of last week, the number of affected organisations was closing in on 400 and individual victims exceed 20 million.

The attack highlights the need for organisations to have policies and procedures in place for third parties, and to be aware of the data which a third party supplier has on them. It will be the organisation who will need to let their customers know in the event of a breach.

https://www.theregister.com/2023/07/20/moveit_victim_count/

  • IT Worker Jailed for Impersonating Ransomware Gang to Extort Employer

28-year-old Ashley Liles, a former IT employee, has been sentenced to over three years in prison for attempting to blackmail his employer during a ransomware attack. Liles, an IT security analyst at an Oxford-based company in the UK, exploited his position to intercept a ransomware payment following an attack suffered by his employer. To deceive the company, he impersonated the ransomware gang extorting them. He tried to redirect the ransomware payments by switching the cyber criminals' cryptocurrency wallet to one under his control. He also accessed a board member's private emails over 300 times.

Insider threat is a risk that organisations need to be aware of and, although it was malicious in this case, it can also come from employee negligence. Organisations looking to achieve a strong level of cyber resilience should incorporate insider risk into their training and controls.

  • Stabilising the Cyber Security Landscape: The CISO Exodus and the Rise of vCISOs

In today's evolving digital landscape, the role of a chief information security officer (CISO) is critical. These professionals defend against the rising tide of daily cyber threats. Yet many CISOs are leaving or considering leaving their jobs; this trend seems to reflect the intense pressure CISOs endure. They face a constant stream of complex cyber threats, manage compliance issues and struggle with a talent deficit in cyber security. Paired with high expectations, many reconsider their roles which can lead to a leadership gap.

A virtual CISO (vCISO) is an outsourced security practitioner who offers their expertise to businesses on a part-time or contractual basis. These professionals provide many of the same services as a traditional CISO, such as developing and implementing security strategies, ensuring compliance with regulations, training staff and managing a company's cyber security posture. vCISOs, such as from Black Arrow, are often part of a larger team and can bring a wide range of experiences and skills. They are exposed to diverse security landscapes across industries, and can provide a fresh perspective and innovative solutions to your security challenges. The vCISO model may not replace the need for a full-time CISO in all cases, but it can certainly add a flexible and cost-effective tool to the arsenal of businesses looking to bolster their cyber security posture.

  • Risk is Driving Medium-Sized Business Decisions

Small and medium sized businesses (SMBs) have long lacked the tools, expertise, staff and budget to make major cyber security investments. However, as threats become more mainstream and more advanced, the focus is shifting, so SMBs need to take the threats seriously and evaluate their cyber security controls.

In a survey of 140 SMBs, it was found that 40% of respondents believe they are very likely or extremely likely to experience a cyber security attack target in the next 12 months. That fear is founded, as 34% of organisations stated they experienced a malware attack in the past year, and 29% experienced a phishing or spear phishing incident. SMBs are putting their time, energy, and budget toward risk management. When it came to budgeting, 67% list their primary budgeting method as “risk-based”, and only 32% as “ad hoc/following an attack or breach”. It was found that over two-thirds of businesses would rather spend money now than pay a ransom later.

  • Talent and Governance, Not Technology, are Key to Drive Change Around Cyber Security

For the last 20 years, large organisations have been spending significant amounts of money on cyber security products and solutions, on managed services, or with consultancies large and small. Yet maturity levels remain elusive: a report found that 70% of firms surveyed had yet to fully advance to a mature-based approach. Cyber security good practices have been well established for the best part of the last 20 years and continue to provide, in most industries, an acceptable level of protection against most threats and an acceptable level of compliance against most regulations.

However cyber security is often viewed as something external to the business. This perspective leads to talent alienation and execution failures because the employees who should be invested in maintaining and improving cyber security may feel disconnected from these efforts. To make genuine progress, cyber security needs to be intrinsically linked to business values as a visible priority, owned and directed from the highest levels of an organisation.

This approach underlines the importance of governance in setting effective cyber security policies and procedures. It also highlights the crucial role of nurturing talent within the organisation to ensure active involvement in maintaining and improving cyber security measures. While technology is undoubtedly an essential element of cyber security, prioritising talent and governance can lead to lasting progress.

  • Hybrid Work, Digital Transformation can Exploit Security Gaps

A new study showed that larger organisations generally recognise malware threats but they lack protection against malicious actors and ways to properly remediate infections. The report revealed security leaders are concerned about attacks that leverage malware-exfiltrated authentication data. 53% say they are extremely concerned about attacks, with 1% of security leaders saying they weren’t concerned at all. 98% said that better visibility into at-risk applications would significantly improve their security posture.

The most overlooked entry points for malware include 57% of organisations allowing employees to sync browser data between personal and corporate devices. 54% of organisations struggle with shadow IT, due to employees’ unsanctioned adoption of applications and systems, creating gaps not only in visibility but also in basic security controls and corporate policies.

  • Human Cyber Risk Can Be Demonstrably Mitigated by Behaviour Changing Training

The process of encouraging secure cyber habits in end users is evolving from traditional awareness training toward changing end user behaviour. It reflects a growing acceptance that traditional methods haven’t worked. While traditional security awareness teaches users how to recognise social engineering, new behaviour changing trains the brain – almost pre-programs it – on the correct recognition and response to phishing.

What is considered a standard phishing email today may not be tomorrow, and changes in user behaviour will help to combat this. It is simply not enough to be shown one phishing email and be told to follow procedures. Training should instead be focused on going beyond; this should look to change how the user approaches things such as phishing, and gamifying the recognition and reporting of it.

  • AI Tool WormGPT Enables Convincing Fake Emails For BEC Attacks

A generative AI tool, WormGPT, has emerged as a powerful weapon in the hands of cyber criminals, specifically for launching business email compromise (BEC) attacks, according to new findings. The tool is designed for malicious purposes and has no restrictions on what a user can request. Such a tool allows for impeccable grammar in emails to reduce suspicion and allows sophistication with no restrictions on prompts. The lowered entry threshold enables cyber criminals with limited skills to execute sophisticated attacks, democratising the use of this technology.

  • Pro-Russian Hacktivists Increase Focus on Western Targets

‘Anonymous Sudan’, apparent pro-Russian hacktivists, claimed a one-hour distributed denial of service attack on the social platform OnlyFans last week. This was the latest in a string of operations aimed at targets in the US and Europe. The group’s digital assaults coincide with attacks coming from a broader network of hackers aligned with Moscow that seek attention by taking down high-profile victims and strategic targets; many of the targets support Ukraine in its ongoing war against Russia.

The pro-Russian group appears to be affiliated with Killnet, a pro-Russian hacktivist group that emerged in late 2021 or early 2022 and has claimed distributed denial of service (DDoS) attacks, data theft and leaks on perceived adversaries of the Russian government, according to an analysis from Google’s Mandiant released earlier this week. The collective’s apparent significant growth in capabilities, demonstrated by Microsoft’s confirmation that Anonymous Sudan was responsible for the outages they experienced, potentially indicates a significant increase in outside investment in the collective, further suggesting a potential tie to the Russian state.

  • Infosec Doesn't Know What AI Tools Organisations Are Using

With the marketplace awash in new artificial intelligence (AI) tools and new AI features being added to existing tools, organisations are finding themselves lacking visibility into what AI tools are in use, how they are used, who has access, and what data is being shared. As businesses try, adopt, and abandon new generative AI tools, it falls on enterprise IT, risk, and security leaders to govern and secure their use without hindering innovation. While developing security policies to govern AI use is important, it is not possible without knowing what tools are being used in the first place.

Enterprise security teams have to consider how to handle discovery, learning which generative AI tools have been introduced into the environment and by whom, as well as risk assessment.

  • Google Restricting Internet Access to Some Employees to Reduce Cyber Attack Risk

In a bid to shrink the attack surface of its employees, and thus boost security, Google is taking an experimental, and some might say extreme, approach: cutting some of their workstations off from the internet. The company originally selected more than 2,500 employees to participate and will disable internet access on the selected desktops, except for internal web-based tools and Google owned websites like Google Drive and Gmail. Some workers who need the internet to do their job will get exceptions, the company stated in materials.

Google is running the programme to reduce the risk of cyber attacks, according to internal materials. If a Google employee’s device is compromised, the attackers may have access to user data and infrastructure code, which could result in a major incident and undermine user trust. The program comes as companies face increasingly sophisticated cyber attacks. Just last week, Microsoft said Chinese intelligence hacked into company email accounts belonging to two dozen government agencies in the US and Western Europe, including the US State Department, in a “significant” breach.

  • Unlocking Business Potential: How CISOs are Transforming Cyber Security into a Strategic Asset

Enterprises are responding to growing cyber security threats by working to make the best use of tools and services to ensure business resilience, according to a recent report. Chief information security officers (CISOs) and virtual CISOs (vCISOS) in particular, want more solutions and services that help them align security measures with enterprise objectives and C-level executives have become more aware of the need for cyber resilience. As a result, security investments have expanded beyond detection and response to include rapid recovery and business continuity.

The report found that amongst other things, enterprises are investing in risk assessments and outsourcing more services. In some cases, where a CISO cannot be hired, organisations may look to hire a vCISO. It is important that the vCISO is able to understand cyber in context to the business and help to align security objectives with the organisations objectives. Black Arrow supports clients as their vCISO with specialist experience in cyber security risk management in a business context.

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 Attacks Are a War We'll Never Win, But We Can Defend Ourselves

The cyber threat landscape is constantly evolving, with hackers becoming more creative in their exploitation of businesses and personal data. As the frequency and sophistication of cyber attacks increase, it's clear that the cyber security war is an endless series of battles that demand constant innovation and vigilance. Recognising the necessity of having built-in security, organisations should integrate security measures into their systems and foster a culture of security awareness.

Acknowledging that breaches are an inevitable risk, an orchestrated team response, well-practiced recovery plan, and effective communication strategy are key to managing crises. Organisations must also invest in proactive security measures, including emerging technologies to spot intrusions early. Ultimately, cyber security isn't just a technical concern, it's a cultural and organisational imperative, requiring the incorporation of security measures into every aspect of an organisation's operations and philosophy.

  • Helping Boards Understand Cyber Risks

A difference in perspective is a fundamental reason board members and the cyber security team are not always aligned. Board members typically have a much broader view of the organisation’s goals, strategies, and overall risk landscape, where CISOs are responsible for assessing and mitigating cyber security risk.

It’s often a result of the board lacking cyber security expertise among its members, the complexity with understanding the topic and CISOs who focus too heavily on technical language during their discussions with the board which can cause a differing perspective. For organisations to be most effective in their approach to cyber security, they should hire CISOs or vCISOs who wear more than one hat and are able to understand cyber in context to the business. In addition, having cyber expertise on the board will pay dividends; this can be achieved by direct hiring or upskilling of board members.

Black Arrow supports clients as their vCISO or Non-Executive Director (NED) with specialist experience in cyber security risk management in a business context.

https://www.helpnetsecurity.com/2023/07/11/david-christensen-plansource-board-ciso-communication/

  • Enterprise Risk Management Should Inform Cyber Risk Strategies

While executives and boards once viewed cyber security as a primarily technical concern, many now recognise it as a major business issue. A single serious data breach could result in debilitating operational disruptions, financial losses, reputational damage, and regulatory penalties.

Cyber security focuses on protecting digital assets from threats, while enterprise risk management adopts a wider approach, mitigating diverse risks across several domains beyond the digital sphere. Rather than existing in siloes, enterprise risk management and cyber risk management strategies should complement and inform each other. By integrating cyber security into their risk management frameworks, organisations can more efficiently and effectively protect their most valuable digital assets.

https://www.techtarget.com/searchsecurity/tip/Enterprise-risk-management-should-inform-cyber-risk-strategies

  • Law Firms at High Risk of Attack as Ransomware Groups Begin to Focus Attention

Three of the largest US law firms have been newly hit by the Cl0p cyber syndicate as part of dozens of ransomware attacks across industries that so far have affected more than 16 million people. All three law firms feature on Cl0p’s leak site, which lists organisations who Cl0p have breached.

This comes as the UK National Cyber Security (NCSC) noted in a report the threat to the legal sector. Law firms are a particularly attractive target for the depth of sensitive personal information they hold from individuals and companies, plus the dual threat of publishing it publicly should a ransom demand go unmet. In Australia, law firm HWL Ebsworth confirmed several documents relating to its work with several Victorian Government departments and agencies had been released by cyber criminals to the dark web following a data breach announced in April 2023.

The extortion of law firms allows extra opportunities for an attacker, including exploiting opportunities for insider trading, gaining the upper hand in negotiations and litigation, or subverting the course of justice. Based on the above, it is no wonder the Solicitors Regulation Authority (SRA) in the UK found that 75% of the law firms they visited has been a victim of a cyber attack.

https://www.helpnetsecurity.com/2023/07/10/law-firm-cyberattack/

  • 20% of Malware Attacks Bypass Antivirus Protection

In the first half of 2023, researchers found that 20% of all recaptured malware logs had an antivirus program installed at the time of successful malware execution. Not only did these solutions not prevent the attack, they also lack the automated ability to protect against any stolen data that can be used in the aftermath.

The researchers found that the common entry points for malware are permitting employees to sync browser data between personal and professional devices (57%), struggling with shadow IT due to employees' unauthorised use of applications and systems (54%), and allowing unmanaged personal or shared devices to access business applications (36%).

Such practices expose organisations to subsequent attacks, like ransomware, resulting from stolen access credentials. Malware detection and quick action on exposures are critical; however, many organisations struggle with response and recovery with many firms failing to have robust incident response plans.

https://www.helpnetsecurity.com/2023/07/13/malware-infections-responses/

  • Ransomware Payments and Extortion Spiked Compared to 2022

A recent report from Chainalysis found that ransomware activity is on track to break previous records, having extorted at least $449.1 million through June. For all of 2022, that number didn’t even reach $500 million. Similarly, a separate report using research statistics from Action Fraud UK, the UK’s national reporting centre for fraud, found cyber extortion cases surged 39% annually.

It’s no wonder both are on the rise, as the commonly used method of encrypting data behind a ransom is being combined with threatening to leak data; this gives bad actors two opportunities to gain payment. With this, the worry about the availability of your data now extends to the confidentiality and integrity of it.

https://www.infosecurity-magazine.com/news/cyber-extortion-cases-surge-39/

  • AI, Trust, and Data Security are Key Issues for Finance Firms and Their Customers

Business leaders have been warned to expect more instability and uncertainly following on from the unpredictable nature of events during the past few years, from COVID-19 to business restructurings, the Russian invasion of Ukraine and the rise of generative artificial intelligence (AI). A recent report found that customers feel they lack appropriate guidance from their financial providers during times of economic uncertainty; the lack of satisfactory experience and a desire for a better digital experience is causing 25% of customers to switch banks.

The report also found that 23% of customers do not trust AI and 56% are neutral. This deficit in trust can swing in either direction based on how Financial Services Institutions (FSIs) use and deliver AI-powered services. While the benefits of AI are unclear, an increased awareness of personal data security has made trust between providers and customers more crucial than ever. In fact, 78% of customers say they would switch financial service providers if they felt their data was mishandled.

https://www.zdnet.com/article/ai-trust-and-data-security-are-key-issues-for-finance-firms-and-their-customers/

  • Caution: Microsoft Warns of Office Zero-Day Attacks with No Patch Available

Russian spies and cyber criminals are actively exploiting still-unpatched security flaws in Microsoft Windows and Office products, according to an urgent warning from Microsoft. While Microsoft recently released patches for 130 vulnerabilities, including 9 criticals, 6 which are actively being exploited (see our advisory here), a series of remote code execution vulnerabilities were not addressed, and attackers have been actively exploiting them because the patches are not yet available.

An attacker could create a specially crafted Microsoft Office document that enables them to perform remote code execution in the context of the victim. All an attacker would have to do is to convince the victim to open the malicious file. Microsoft have stated that a security update may be released out of cycle to address these flaws.

https://www.securityweek.com/microsoft-warns-of-office-zero-day-attacks-no-patch-available/

  • Scam Page Volumes Surge 304% Annually

Security researchers have recorded a 62% year-on-year increase in phishing websites and a 304% surge in scam pages in 2022. The Digital Risk Trends 2023 report classifies phishing as a threat resulting in the theft of personal information and a scam as any attempt to trick a victim into voluntarily handing over money or sensitive information.

It found that the average number of instances in which a brand’s image and logo was appropriated for use in scam campaigns increased 162% YoY, rising to 211% in APAC. Scams are also becoming more automated, as the ever-increasing number of new tools available to would-be cyber criminals has lowered the barrier of entry. We expect to see AI also play a greater role in scams in the future.

https://www.infosecurity-magazine.com/news/scam-page-volumes-surge-304/

  • Financial Industry Faces Soaring Ransomware Threat

The financial industry has been facing a surge in ransomware attacks over the past few years, said cyber security provider SOCRadar in a threat analysis post. This trend started in the first half of 2021, when Trend Micro saw a staggering 1,318% increase in ransomware attacks targeting banks and financial institutions compared to the same period in 2020. Sophos also found that over half (55%) of financial service firms fell victim to at least one ransomware attack in 2021, a 62% increase from 2020.

https://www.infosecurity-magazine.com/news/financial-industry-faces-soaring/

  • The Need for Risk-Based Vulnerability Management to Combat Threats

Cyber attacks are increasing as the number of vulnerabilities found in software has increased by over 50% in the last 5 years. This is a result of unpatched and poorly configured systems as 75% of organisations believe they are vulnerable to a cyber attack due to unpatched software. As vulnerabilities continue to rise and security evolves, it is becoming increasingly apparent that conventional vulnerability management programs are inadequate for managing the expanding attack surface. In comparison, a risk-based strategy enables organisations to assess the level of risk posed by vulnerabilities. This approach allows teams to prioritise vulnerabilities based on their assessed risk levels and remediate those with higher risks, minimising potential attacks in a way that is continuous, and automated.

By enhancing your vulnerability risk management process, you will be able to proactively address potential issues before they escalate and maintain a proactive stance in managing vulnerabilities and cloud security. Through the incorporation of automated threat intelligence risk monitoring, you will be able to identify significant risks before they become exploitable.

https://www.bleepingcomputer.com/news/security/the-need-for-risk-based-vulnerability-management-to-combat-threats/

  • Government Agencies Breached in Microsoft 365 Email Attacks

Microsoft disclosed an attack against customer email accounts that affected US government agencies and led to stolen data. While questions remain about the attacks, Microsoft provided some details in two blog posts on Tuesday, including attribution to a China-based threat actor it tracks as Storm-0558. The month long intrusion began on 15 May and was first reported to Microsoft by a federal civilian executive branch (FCEB) agency in June.

Microsoft said attackers gained access to approximately 25 organisations, including government agencies. While Microsoft has mitigated the attack vector, the US Government Cybersecurity and Infrastructure Security Agency (CISA) was first to initially detect the suspicious activity. The government agency published an advisory that included an attack timeline, technical details and mitigation recommendations. CISA said an FCEB agency discovered suspicious activity in its Microsoft 365 (M365) environment sometime last month.

  • Concerns Raised as Report Questions UK’s “Completely Inadequate” Defence to Threats from China

Britain’s spy watchdog has slammed the UK Government for a “completely inadequate” response to Chinese espionage and interference which risked an “existential threat to liberal democratic systems”. In a bombshell 207 page report, Parliament’s Intelligence and Security Committee issued a series of alarming warnings about how British universities, the nuclear sector, Government and organisations alike were being targeted by China.

  • Hackers Backed by North Korea have Stolen Billions of Dollars Over the Last Five Years

Hackers have developed a list of sophisticated tricks that allow them to weasel their way into the networks of possible targets, including organisations. Sometimes a North Korean hacker would pose as a recruitment officer to get an employee’s attention. The cyber criminal would then share an infected file with the unsuspecting company employee. This was the case of the famous 2021’s Axie Infinity hack that allowed the North Koreans to steal more than $600 million after one of the game developers was offered a fake job by the hackers.

Black Arrow Cyber Advisory 12 July 2023 – Microsoft Patch Tuesday, including 6 actively exploited vulnerabilities, and Adobe Updates

Black Arrow Cyber Advisory 12 July 2023 – Microsoft Patch Tuesday, including 6 actively exploited vulnerabilities, and Adobe Updates

Executive summary

Microsoft’s July 2023 Patch Tuesday provides updates to address 138 security issues across its product range, including six actively exploited zero-day vulnerability. The exploited zero-day vulnerabilities use a range of Microsoft Windows products to bypass security features, elevate privileges and perform remote code execution. Among the updates provided by Microsoft 9 addressed critical vulnerabilities.

What’s the risk to me or my business?

The actively exploited vulnerabilities could allow an attacker with standard user access, to gain elevated privileges, or install kernel drivers, depending on the exploit used. Other risks such as bypassing security features of Microsoft Outlook and performing remote code execution can occur. This could allow an attacker to further compromise the confidentiality, integrity and availability of the organisation’s information assets.

What can I do?

Security updates are available for all supported versions of Windows impacted. The updates should be applied as soon as possible for the actively exploited vulnerability and all other vulnerabilities.  Other mitigations have been provided by Microsoft and can be found below in the further detail’s section.

Technical Summary

CVE-2023-32046 – The actively exploited vulnerability targets MSHTML Platform which could allow an attacker to elevate their privileges to the rights the user that is running the affected application is.

CVE-2023-32049 – This actively exploited vulnerability targets Windows SmartScreen allowing an attacker to bypass security features including the security warning prompt.

CVE-2023-36874 – This actively exploited vulnerability targets the Windows Error Reporting Service allowing an attacker to elevate privileges allowing them to gain administrator privileges.

CVE-2023-36884 – This actively exploited vulnerability targets the Office and Windows HTML allowing an attacker to perform remote code execution.

CVE-2023-35311 – This actively exploited vulnerability targets Microsoft Outlook and bypasses a security feature however to exploit this an attacker would have to have a user click in a specially crafted link through phishing or social engineering.

ADV230001 – This is a Microsoft signed driver that has been maliciously used in post-exploitation activity which abused a Windows policy loophole to install malicious kernel-mode drivers.


Adobe

This month, Adobe released fixes for 4 vulnerabilities, of which 3 were rated critical across Adobe InDesign and Adobe ColdFusion. At current, Adobe are not aware of any active exploitation of the listed vulnerabilities, however the advice is to update the affected products using their priority rating which can be found in the details below. The vulnerabilities include remote code execution, memory leak and security bypass.

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 Attacks Against Mobile Devices Growing Fast

A rise in mobile-powered businesses is creating vulnerability gaps that are being exploited by cyber criminals and nation-states, according to a new report. 43% of all compromised devices were fully exploited, not just jailbroken or rooted, which is an increase of 187% year-over-year.  The report found that the average user is 6 to 10 times more likely to fall for an SMS phishing attack than an email based attack.

It was also found that there was a 138% increase in critical Android vulnerabilities discovered in 2022, while Apple iOS accounted for 80% of the zero-day vulnerabilities actively being exploited in the wild. With malware increasingly spreading through legitimate channels, such as official marketplaces and ads in popular apps. This is true for both scam apps and dangerous mobile banking malware. For organisations, no matter if they are corporate-owned or part of a BYOD strategy, the need to implement appropriate security controls, and educate end-users about potential threats, is critical.

  • One Third of Security Breaches Go Unnoticed by Security Professionals

While surface-level confidence around hybrid cloud security is high, with 94% of global respondents stating their security tools and processes provide them with complete visibility and insights into their IT infrastructure, the reality is nearly one third of security breaches are not spotted by IT and security professionals, according to a recent report.

The report highlighted that 50% of IT and security leaders lack confidence when it comes to knowing where their most sensitive data is stored and how it is secured. The issue is that 31% of breaches are being identified later down the line, rather than pre-emptively using security and observability tools either by data appearing on the dark web, files becoming inaccessible, or users experiencing slow application performance (likely due to DoS or inflight exfiltration). This number rises to 48% in the US, and 52% in Australia.

https://www.helpnetsecurity.com/2023/07/03/hybrid-cloud-security-breaches/

  • Cyber Security Experts Have Become Targets for Board Seats

The need for strong cyber security programs is a vital part of doing business today, and a good reflection of that is adding security executives to Boards. The trend is for chief information security officers (CISOs) to be elevated to the board of directors, as risk and regulatory compliance become more visible in an organisation, many of the initiatives and controls will be security related, addressing those controls usually falls to the CISO.

The research also showed that 90% of public companies lack even one qualified cyber expert, showing a significant cyber board supply-demand gap. With only 15% of CISOs have broader traits required for board level positions, such as a holistic understanding of the business, a global perspective and ability to navigate a range of stakeholders, with another 33% having a subset of those necessary traits.

CISOs are hard to come by and few have the requisite Board level experience. To fill this gap Black Arrow provide a virtual CISO (vCISO) where you get a whole team of highly skilled and experienced professionals for less than you would pay for one permanent resource, and firms can also take advantage of Black Arrow’s Cyber NED, incorporating Board, Governance, Finance, HR and Risk experience with specialist cyber expertise and experience.

  • Phishing Attack Prevention as Email Attacks Surge Over 450%

A Recent report found that email attacks had surged 464% this year compared to the previous year as phishing attacks remain amongst the most used tactics by attackers due to their high success rate and the ease in which they can be conducted. For preventing such attacks, the following principles will help mitigate: not clicking on unknown links, not trusting unknown sites, enabling multi-factor authentication, hardly disclosing personal information and having increased phishing awareness.

In an organisation, such awareness and principles can be highlighted and continually reinforced through having an effective awareness training programme. This in turn, will help to create a cyber aware culture and reduce the risk of someone in the organisation falling victim to phishing.

  • Outsmarting Business Email Compromise (BEC) Scammers

Last year the FBI registered over 21,000 complaints about business email fraud, with adjusted losses of over $2.7 billion. Today this line of attack shows no sign of slowing down. Business email compromise (BEC) techniques are increasingly sophisticated and cyber crime-as-a-service (CaaS) along with AI have lowered the barrier to entry for threat actors.

There are six key elements which can help to mitigate the impact of BEC, these are; inbox protection, strong authentication, secure emails, zero-trust control, secure payment processes and education. Putting the brakes on this con game takes the entire organisation, from the C-suite and IT, compliance, and risk management teams to every business unit. Awareness, backed by policy and technology, is the crucial factor in a consistently strong defence.

  • Small Organisations Face Security Threats on a Limited Budget

Small organisations face the same security threats as larger organisations overall but have less resources to address them. The most common security incidents faced are phishing, ransomware, and user account compromise also known as business email compromise (BEC). However, smaller organisations usually have fewer resources and experience with which to address security threats. Indeed, lack of budget is their top security challenge, reported by one in two small companies.

The lack of budget won’t stop a threat actor from attacking however, and so small organisations need to be able to effectively identify, prioritise and mitigate against security incidents. This may require small organisations outsourcing some of their cyber strategy, to allow them access to expertise.

https://www.helpnetsecurity.com/2023/07/05/small-organizations-security-threats/

  • Cloud Security: Sometimes the Risks May Outweigh the Rewards

Threat actors are well-aware of the vulnerabilities in the cloud infrastructure. IT teams and decision-leadersmakers must have a clear understanding of the types of cloud services and the associated risk of cyber attacks associated. Around two in five (39%) businesses experienced a data breach in their cloud environment in 2022, a rise of 4% compared with 2021, a new report has found. The leading cause of cloud data breaches was human error, at 55%, according to the report. This was significantly above the next highest factor identified by respondents (21%), which was exploitation of vulnerabilities.

Other issues can arise from the cloud as it gives organisations the opportunity to create large amounts of infrastructure quickly and easily, which leaves it exposed to the possibility of substandard security configurations being applied to it. Due to the ease of use of cloud services, companies might become negligent in terms of their security.

https://www.infosecurity-magazine.com/news/human-error-cloud-data-breaches/

  • Cl0p's MOVEit Campaign Represents a New Era in Cyber Attacks

A number of organisations impacted by the mass hacks exploiting a security flaw in the MOVEit file transfer tool, including energy giant Shell and US-based First Merchants Bank, have confirmed that hackers accessed sensitive data. The ransomware group shows an evolution of its tactics with the MOVEit zero-day, potentially ushering in a new normal when it comes to extortion supply chain cyber attacks, experts say.

From what the industry has seen in recent Cl0p breaches, GoAnywhere, MFT and MOVEit, they have not executed ransomware to encrypt data within the target environments. The operations have strictly been exfiltrating data and using that stolen information for later blackmail and extortion. The MOVEit vulnerability isn't an easy or straightforward one, it required extensive research into the MOVEit platform to discover, understand, and exploit this vulnerability. The skill set required to uncover and exploit this vulnerability isn't easily learned and is hard to come by in the industry. This operation isn't something Cl0p ransomware group usually does, which is another clue leading to suspect Cl0p acquired the MOVEit zero-day vulnerability rather than developing it from scratch. Something future groups may decide to adopt.

  • 75% of Consumers Prepared to Ditch Brands Hit by Ransomware

As 40% of consumers harbour scepticism regarding organisations’ data protection capabilities, 75% would shift to alternate companies following a ransomware attack a recent report found. Furthermore, consumers request increased data protection from vendors, with 55% favouring companies with comprehensive data protection measures such as reliable backup and recovery, password protection, and identity and access management strategies.

While 37% of Gen Z prefers an apology from companies experiencing a ransomware attack, ranking 12% higher than monetary compensation, Baby Boomers are less forgiving. 74% of them agree their trust in the vendor is irreparably damaged after suffering more than one ransomware attack, compared to only 34% of Gen Z.

https://www.helpnetsecurity.com/2023/07/05/consumers-data-protection-request/

  • Scammers Using AI Voice Technology to Commit Crimes

The usage of platforms like Cash App, Zelle, and Venmo for peer-to-peer payments has experienced a significant surge, with scams increasing by over 58%. Additionally, there has been a corresponding rise of 44% in scams stemming from the theft of personal documents according to a recent report.

The report also highlights the rise of AI voice scams as a significant trend in 2023. AI voice technology enables scammers to create remarkably realistic voices and convincingly imitate family members, friends and other trusted individuals. With just a short voice clip usually taken from social media, a scammer can clone a loved one’s voice and call a victim pretending to be that person. The scammer deceives the victim into thinking their loved one is in distress to get them to send money, provide personal information or perform other actions. AI voice technology has gotten to the point where a mother can’t tell the difference between her child’s voice and a machine, and scammers have pounced on this to commit crimes.

https://www.helpnetsecurity.com/2023/07/07/ai-voice-cloning-scams/

  • What are the Causes of Data Loss and What it the Impact on Your Organisation?

In today’s digital age, data has become the lifeblood of organisations, driving critical decision-making, improving operational efficiency, and allowing for smoother innovation. Simply put, businesses heavily rely on data. In an era where data has become the cornerstone of business operations, the loss of vital information can result in severe setbacks and irreparable damage. Whether it’s due to accidental deletion, hardware failure, cyber-attacks, or natural disasters, the loss of valuable data can have devastating impacts on an organisation.

It's imperative that businesses understand different types of data (structured, unstructured, semi-structured, metadata) and deploy tailored protection strategies. A significant 26% of companies suffered data loss in 2022, underlining the need for robust data security measures like regular backups, cyber security protocols, employee training, and data encryption. Effective data loss prevention can shield organisations from severe impacts like intellectual property theft, operation disruption, and legal repercussions.

https://securityaffairs.com/148086/security/impacts-of-data-loss.html

  • Ransomware Affiliates, Triple Extortion, and the Dark Web Ecosystem

Many people associate the dark web with drugs, crime, and leaked credentials, but in recent years the dark web has emerged as a complex and interdependent cyber crime ecosystem, exemplified by the increasingly complex methods used to extort companies.

One of the more recent trends we see is that groups are now setting up infrastructure, in some cases outsourcing actual infection (and in some cases negotiation) to “affiliates” who effectively act as contractors to the Ransomware as a Service (RaaS) group and split the profits at the end of a successful attacks. The world of cyber crime is ever-evolving and it is no easy task to stay on top of the changing landscape.

Black Arrow Cyber Advisory – 06 July 2023 – Microsoft Teams Vulnerability Allows Malware Delivery from External Accounts

Black Arrow Cyber Advisory – 06 July 2023 – Microsoft Teams Vulnerability Allows Malware Delivery from External Accounts

Executive Summary

A vulnerability has been discovered in Microsoft Teams, which allows malicious actors to circumvent the application's built-in restrictions for files originating from external sources. The ‘TeamsPhisher’ application which has been developed by the US Navy’s Red Team which is freely available, takes advantage of this technique to easily allow an attacker to send a malicious attachment to a targeted set of Teams users. Exploiting this vulnerability enables attackers to distribute malware to users using accounts that are external to a targets Microsoft Tennant, posing significant risks to individuals and businesses.

What’s the risk to me or my business?

Exploiting this vulnerability enables malicious actors to engage in social engineering and phishing attacks by leveraging Microsoft Teams as a communication platform. Furthermore, it bypasses all built-in security restrictions, allowing the delivery of malicious payloads directly to users' inboxes. Clicking or launching these payloads can grant attackers further access to your systems, compromising the confidentiality, integrity, and availability of your organization's data.

What can I do?

At this time Microsoft has not yet issued a fix to this problem but has provided the following statement to ‘Bleeping Computer’: “We’re aware of this report and have determined that it relies on social engineering to be successful.

We encourage customers to practice good computing habits online, including exercising caution when clicking on links to web pages, opening unknown files, or accepting file transfers.”

To mitigate the risk, it is advised that you turn off communication with external tenants. However if this is not possible due to needing to regularly communicate with clients it is advised to change the security settings to only whitelist certain required domains. Both actions can be done in Microsoft Teams Admin Center > External Access. It is important to emphasise within your organisation that phishing attacks can happen in various forms, other than emails. Therefore, it is essential to maintain constant vigilance in all aspects of online communication.

Black Arrow Cyber Insight 06 July 2023 – NHS Trust Breached, Personal Information Leaked

Black Arrow Cyber Insight 06 July 2023 – NHS Trust Breached, Personal Information Leaked

Executive Summary

Last weekend, Barts Health NHS trust was breached in a cyber attack, with Russian-linked cyber crime gang ALPHV, also known as BlackCat. The attackers claimed to have acquired seven terabytes of internal documents from the trusts’ systems.  A selection of files including copies of driving licenses, passports and correspondence have already been leaked. It is believed that more is to come. This comes after other recent cyber attacks, such as the MOVEit hack, which has impacted over 130 organisations and 15 million individuals.

What’s the risk to me or my business?

The availability of such detailed personal information poses an increased risk of threat actors exploiting it for phishing purposes, and also increases the likelihood that the information could be used for identity fraud. With access data such as previous email chains with an individual, phishing attacks can appear more authentic as responses to legitimate requests, making them more likely to succeed.

What can I do?

To help mitigate the risk, Black Arrow strongly recommend maintaining a high level of vigilance and awareness. It is crucial to understand that the presence of personal or confidential information alone does not guarantee authenticity. Take the time to double-check any suspicious communication or requests before sharing sensitive information. By remaining cautious and verifying the legitimacy of any unexpected or unusual messages, you can reduce the likelihood of falling victim to phishing attacks. It is also recommended that individuals monitor their own personal accounts for suspicious activity including the information stored with credit unions such as Equifax and Transunion to identify potential cases of identity theft.
