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.

The Human Element- Cyber Security’s Great Challenge

According to Verizon’s 2023 Data Breach Investigations Report, 74% of all breaches involved a human element. It is important for organisations to understand that it is not simply malicious employees or employees falling for social engineering attacks; it includes things such as negligent, or intentional but not malicious actions. In fact, a recent separate report by Kaspersky found that 26% of incidents over the past two years involved the result of intentional security protocol violations; in comparison, external hacking attempts made up 20%.

Further, Kaspersky found 25% of incidents occurred due to neglecting system software or application updates, followed by 22% resulting from deliberate use of weak passwords or failing to change them promptly, and 18% from staff visiting unsecured websites. One potential cause for these incidents is a lack of training on why such protocols need to be followed.

Black Arrow provides live in person and online instructor lead cyber security training including Cyber Risk and Governance Workshops for Senior Leadership, and Awareness, Behaviour and Culture Training for employees and contractors.

Good Cyber Hygiene is a Strategic Imperative for SMEs, Report Shows

Small or large, no company is immune to a cyber attack and therefore good cyber hygiene is an imperative for all. Whilst large firms may already have more mature defences in place, smaller firms are definitely catching on to this, with 47% of respondents to a recent survey stating they were more worried about their organisation’s security posture now than compared to six months ago.

The survey found that ransomware (35%), software vulnerability exploits (28%) and using the same password across different applications (25%) were amongst the largest concerns. Interestingly, in a separate report, 44% of incidents were found to lack any element of malware, indicating that attackers are moving beyond traditional methods. The same report found 65% of cases included remote monitoring and management tools as the vector for initial access, something a number of organisations do not secure.

Business email compromise (BEC) attacks are also a key concern for businesses of all sizes but can be especially damaging to smaller organisations for whom the financial loss can be devastating.

Despite Increasing Ransomware Attacks, Some Companies are in Denial

A recent study has highlighted a contradiction in the way organisations perceive ransomware threats. Although many do not consider themselves likely targets, they are, nevertheless, bolstering their security measures, expanding their teams, and fortifying cyber defences, acknowledging the risks despite their assumed invulnerability.

Simultaneously, ransomware tactics are undergoing significant changes. The past three quarters have seen a marked increase in double-extortion attacks, with data leaks from these incidents rising by 50% compared to the previous year. This trend is predominantly driven by a few active groups, some newly emerged this year, amplifying the threat landscape.

In a tactical shift, the ransomware group ALPHV, also known as Blackcat, has lodged a formal complaint with the US Securities and Exchange Commission (SEC) against a victim for failing to comply with new disclosure regulations. Meanwhile, LockBit, infamous for attacks on high-profile targets, is modifying its extortion tactics due to lower-than-anticipated ransom returns. These developments point to an evolving and adaptive ransomware environment.

A Single Supply Chain Related Ransomware Incident Spurred UK Decision Makers to Spend Big on Cyber as Latest Victim Count exceeds 2.6K Organisations and 77M People

It is reported that 2,620 organisations and more than 77 million individuals have been impacted to date by the MOVEit supply chain ransomware attack, with millions in the past week alone having received notifications that their information had either been accessed, leaked, or both.

In a survey involving directors of UK companies with over 500 seats that had suffered a ransomware or extortion attack in the past 18 months, it was found that 24% had become significantly more anxious about ransomware attacks as a direct result of the MOVEit breach, and 66% were slightly more anxious. This anxiety translated into action, with 42% of respondents investing more into backup and recovery, and 29% tweaking existing cyber strategies. 29% had taken the decision to amend their existing cyber strategies. Staff training was also found to rise, with 42% looking to spend on skills development and 40% upping their investment in training.

The True Cost of a Ransomware Attack

While the demand is often financial, the impact and reach of ransomware goes far beyond the ransomware demand. Alongside the financial impact, comes the reputational impact, loss of customers, resources in returning to business as normal and time lost in recovery. For some companies, it can take months to return to where they were before and for others, it marks the end of their organisation.

For an attacker, it doesn’t matter. Their goal is not limited by the size or sector of an organisation and it is therefore imperative that every organisation is prepared for the event of an incident. Black Arrow works with organisations of all sizes and sectors to design and prepare for managing a cyber security incident; this can include an Incident Response Plan and an educational tabletop exercise for the leadership team that highlights the proportionate controls to help the organisation prevent and mitigate an incident.

Largest Study of Its Kind Shows Outdated Password Practices Are Putting Millions at Risk

A recent study has exposed serious flaws in passwords on the internet, revealing that three out of four popular websites are compromising user security by not meeting basic password standards. The study examined 20,000 websites, finding many allowed simple passwords, didn’t block common ones and adhered to outdated complexity requirements. It was found that over half the websites accept passwords of six characters or fewer, with 75% not requiring the advised minimum of eight characters, and 30% not supporting spaces or special characters. The study showcases the gap in security measures implementation across the web and emphasises the importance of ongoing improvement in web security standards.

The problem is further exacerbated by employees using work email for non-work approved websites and reusing the same passwords, meaning any breach of a compromised site hands the user’s credentials to an attacker. Further, many organisations are not even aware this is going on.

Cyber Security Investment Involves More Than Just Technology

C-suite business leaders and senior IT professionals within large organisations, found that the top five cyber security investment areas were technologies (49%), threat intelligence (46%), risk assessment (42%), cyber insurance (42%), and third-party risk management (40%). Fewer organisations highlighted technology as good value for money in 2023 (49%) than in 2022 (58%). suggesting an awareness that technology investments go hand-in-hand with investing in governance and personnel to effectively enable and manage the technology.

Black Arrow supports business leaders in organisations of all sizes to demonstrate governance of their cyber security by owning their cyber security strategy and leveraging their existing internal and external resources to build resilience against a cyber security incident.

Questions Leaders Must Ask Themselves on Security Culture

In today's corporate landscape, there's a growing emphasis on the human aspect of cyber security, with Stanford University research indicating that about 88% of data breaches result from employee errors. Companies are now focusing on enhancing security awareness through marketing campaigns and integrating cyber security performance into job reviews. This shift acknowledges that as technological defences evolve, cyber attackers increasingly exploit human vulnerabilities, as evidenced by major ransomware incidents like those impacting Colonial Pipeline and JBS Foods.

Developing a strong security culture is essential, by complementing robust policies with ingraining security-minded beliefs and behaviours in employees. Key to this is the role of leadership in embedding and continuously assessing this culture. This involves evaluating training effectiveness, reporting mechanisms, proactive security approaches, and the impact of security initiatives, while also considering the complexity of human behaviour and the example set by top management. Emphasising these aspects is crucial for maintaining a secure and resilient organisational environment, and in so doing protecting an organisation's reputation and financial integrity.

There’s a Crossover Between Organised Crime, Financial Crime, and Nation-State Crime

The convergence of organised crime, financial crime, and nation-state crime is a growing concern in today’s interconnected world. This crossover, driven by the digital revolution, globalisation, economic factors, and state fragility, is reshaping the global criminal landscape. Organised crime syndicates, traditionally involved in activities like drug trafficking and extortion, are now branching out into financial crimes, offering higher profits with lower risks.

Financial crime, once the domain of individual fraudsters and white-collar criminals, has become a lucrative venture for organised crime groups. They exploit the global financial system to launder proceeds of crime, finance their operations, and evade law enforcement. Nation-state crime, involving state-sponsored or state-condoned criminal activities, often overlaps with organised and financial crime. Some governments turn a blind eye to these activities, while others actively support them for political, economic, or strategic reasons.

Cyber Attack on British Library Highlights Lack of UK Resilience

A recent ransomware attack on the British Library has spotlighted the vulnerabilities in the UK's public sector IT infrastructure, amid rising state-backed cyber attacks. This major incident, which caused a significant technical outage at the library, underscores the concerns of cyber intelligence experts about the government's inadequate investment in cyber resilience in critical areas like education, healthcare, and local government. The hacking group Rhysida, targeting essential infrastructure, claimed responsibility and auctioned stolen data, including British Library employees’ passports, for 20 bitcoin (approximately £600,000).

The attack on the British Library, a key public service institution, highlights the escalating threat of ransomware attacks and their potential exploitation by state actors. The UK’s National Cyber Security Centre (NCSC) has reported a significant increase in cyber attacks in 2023, with incidents more than doubling compared to the previous year. In response, the UK government, which had already allocated £2.6bn for cyber security improvements and IT system updates, is actively assessing the situation with the support of the National Protective Security Authority.

Organisations Rethink Cyber Security Investments to Meet NIS2 and DORA Directive Requirements

The European Union (EU) is seeking to improve cyber resilience across all member states by bringing in two new regulations: the Digital Operational Resilience Act (DORA), which focuses on financial services companies, and its counterpart the Network and Information Systems Directive (NIS2). The effects of the two regulations are likely to be wider reaching, bringing in more stringent processes and controls and redefining service provision to organisations.

With NIS2 coming into effect in October 2024, the mandatory directive will have teeth, with strict penalties for non-compliance for both the business and senior board personnel, who can be held directly accountable and prevented from holding similar positions in the future. It also aims to increase intelligence sharing between member states and enhance supply chain security. This latter measure will see the directive have a global impact.

Many organisations supplying services to firms that fall under DORA and NIS2 will themselves be subject to the full force of the regulations, with many of these suppliers, including IT providers, unaware that this will have far reaching ramifications for them and their ability to continue to provide these services.

The Cyber Security Lawsuit Boards are Talking About

For the last month, an under-the-radar lawsuit has privately been a hot topic of conversation in boardrooms and corporate security departments alike. The lawsuit involved the Securities and Exchange Commission (SEC) accusing SolarWinds and their CISO of fraud. SolarWinds, like many organisations, had disclosed some facts, however what was reported was not sufficient to satisfy the regulator. The lawsuit is the first in which the SEC has charged a company with intentional fraud related to cyber security disclosures and it paints a picture for the wider movement of the cyber landscape. Whilst the SEC is US based you can expect regulatory counterparts in other jurisdictions globally to follow suit.

Black Arrow Cyber Advisory 24 November 2023 – Windows SmartScreen Vulnerability Under Active Exploitation

Executive summary

Financially motivated threat actors are currently exploiting a critical vulnerability in unpatched versions of Windows SmartScreen. The vulnerability which is under exploitation was patched in Microsoft’s November patch Tuesday. Since its patch, a proof of concept exploiting the vulnerability in Windows SmartScreen has become publicly available.

What’s the risk to me or my business?

Windows SmartScreen is a security feature that prevents potentially harmful malware from running. It checks applications or files to ensure that they are safe; if they are not deemed to be safe, it will give the users the option to cancel running them. The now publicly available exploit allows an attacker to cause a victim to automatically run malware, bypassing SmartScreen checks and therefore impacting the confidentiality, integrity, and availability of data. For an attacker to be able to exploit, all they would need is a user to click on a malicious URL.

What can I do?

Black Arrow recommends applying the patches made available by Microsoft immediately, which can be found in our blog post detailed below. Organisations running unpatched versions are leaving themselves at risk of exploitation.

Technical Summary

CVE-2023-36025- A security bypass vulnerability in Windows SmartScreen
