Black Arrow Cyber Threat Intelligence Briefing 05 June 2026

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.

Executive Summary

This week’s review of cyber security in the specialist and general media highlights how business leaders can better understand and manage cyber risks, with insights into actions that boards can take to improve security and resilience.

AI remains a prominent theme, continuing a trend we have observed over recent months. Alongside this, we see cyber risks becoming more complex, spanning geopolitical threats, the evolution of ransomware, and security weaknesses that can emerge through routine business and technology changes. We also highlight the recently announced impact of last year’s M&S cyber attack on executive remuneration, illustrating how the consequences of a cyber incident can extend well beyond the initial disruption.

Our advice for business leaders remains consistent: focus on cyber security to reduce the likelihood of an incident, and on cyber resilience to withstand and recover from one. This requires boards to understand cyber risks in business terms, govern them through proportionate controls, and rehearse the leadership response before an incident occurs. Contact us to discuss how these themes can be addressed in your leadership meetings.

Top Cyber Stories of the Last Week

Why Your Board Is Still Not Ready for Cyber Risk - And What Actually Needs To Change

Cyber incidents have ranked as the top global risk for the fifth year running, according to the Allianz Commercial Risk Barometer, yet many boards still overestimate their organisation’s readiness. A key challenge is proving the return on cyber security investment, particularly where risks involve reputation, customer trust and business disruption. Stronger cyber resilience can reduce downtime, support customer retention and strengthen competitive positioning. Boards should treat cyber risk as a core business issue, with clear ownership, measurable reporting, independent assurance and consideration in strategy, mergers and acquisitions.

Execs Must Treat Cyber Threats as Statecraft, ISACA Expert Says

Information Security professional body ISACA has warned that cyber security risk can no longer be treated as a purely technical issue, as cyber, artificial intelligence and geopolitics are now increasingly connected. High profile attacks against commercial organisations have shown that private companies can become targets for state linked groups, sometimes for political rather than financial reasons. Emerging risks include covert foreign IT worker schemes, which can create trusted insider access. Boards should understand where they are exposed, test their crisis response, strengthen HR and supplier checks, and rehearse longer running scenarios involving nation state threats.

UK Firms Prioritise AI Threat Preparedness as Cyber Risks Evolve

ManageEngine reports that AI-powered attacks are now the top concern for UK organisations, cited by 43% of respondents, with 41% prioritising investment in AI and advanced threat preparedness. More than three quarters of UK businesses experienced a cyber incident in the past year, above the European average, while 46% pointed to skills shortages as their main operational challenge. Although 94% of incidents are detected within 24 hours, recovery remains slower, with over a quarter taking more than 10 days, highlighting the need to strengthen resilience as threats become more complex.

https://www.infosecurity-magazine.com/news/uk-firms-prioritize-ai-threat/

Nation State Attacks: The Risk to UK Firms

The UK’s National Cyber Security Centre has warned that nation states, particularly China, Iran and Russia, are now behind most significant cyber incidents affecting the UK. These attacks are often focused on disruption, espionage or gaining long-term access, rather than financial gain, meaning ransom payments are unlikely to resolve the issue. Critical sectors such as finance, healthcare, technology, telecoms, energy, water and defence face heightened risk, as do suppliers that provide access to larger organisations. Strong basic controls, regular recovery testing and clear oversight remain essential as geopolitical tensions continue to shape cyber activity.

The Gentlemen Are Coming for Your Files, and Then Your Network

Microsoft has warned that ransomware called ‘Gentlemen’, developed by a group with the same name, is actively targeting organisations across education, transport, healthcare and financial services worldwide. First seen in mid 2025 and still active in 2026, the ransomware can spread from one compromised machine to others across a network before encrypting files. This means a single breach can quickly become a wider business disruption. ‘Gentlemen’ now operates as ransomware-as-a-service, where criminal affiliates can pay to use the software to carry out attacks. Early detection of unusual access, stolen password use and remote system activity is critical to limiting impact.

https://www.csoonline.com/article/4178580/the-gentlemen-are-coming-for-your-files-and-then-your-network.html

Ransomware Groups Grow Revenue by Almost 40% in Q1 2026

Rapid7 has reported that ransomware revenue rose by almost 40% year on year in the first quarter of 2026, reaching an estimated $529.2 million. The growth reflects a more mature criminal market, where ransomware groups can buy ready-made access to organisations through dark web brokers rather than breaking in themselves. Leading groups generated significant revenue, with Qilin estimated at $193 million and Gentlemen at $52 million between July 2025 and March 2026. The findings show how resilient and commercialised cyber crime operations have become.

'The Com' Cyberattacks Support Violence & Sexploitation

Researchers report that ‘The Com’, a loose criminal network linked to groups such as Scattered Spider, combines cyber crime with wider criminal activity, blurring the boundaries between its hacking groups and other criminal networks. The group is largely North American, often young, and recruits through gaming and social media communities. Its activity shows how weak cloud security can create harm beyond the breached organisation, with stolen access and extortion funding further criminal operations. Recent activity may have quietened, but researchers warn the group remains active and continues to evolve its tactics.

What Is Configuration Drift - And Why It’s Your Biggest M365 Security Risk

Configuration drift is a growing Microsoft 365 security risk, particularly for managed service providers overseeing many client environments. It occurs when security settings gradually move away from an agreed baseline through routine changes, such as temporary access exceptions, relaxed sharing controls or admin permissions that are not later removed. These changes can weaken defences without triggering obvious alerts. Continuous monitoring and automated remediation can help identify and correct drift quickly, reducing the risk of incidents and supporting stronger governance across multiple Microsoft 365 tenants.

Supply Chain Risk Is Now a Cyber Resilience Problem

AI demand is putting pressure on the supply of DRAM and NAND, the memory and storage components that underpin backup and recovery infrastructure. As availability tightens and costs rise, cyber resilience strategies that rely on continually adding more hardware may become harder to sustain. More efficient architectures, which reduce the amount of data stored, moved and managed, can lower dependency on scarce components, reduce the number of systems needing protection, and support faster recovery. This makes infrastructure efficiency not just a cost issue, but a strategic cyber security consideration.

82% of IT Pros Report a Web-Based Security Incident in Past Year – BYOD, SaaS Tools, and Remote Work Policies All Play a Part in Security Resilience

NordLayer reports a clear gap between confidence and reality in web-based security. While 73% of organisations believe they are prepared for attacks through browsers and web applications, 82% experienced an incident in the past year. The risk is growing as businesses rely more heavily on online software, remote working and personal devices. Malware designed to steal login details harvested 1.8 million credentials and 68.8 billion cookies last year, giving attackers a way to access systems by appearing to log in legitimately rather than forcing their way in.

https://www.techradar.com/pro/security/82-percent-of-it-pros-report-a-web-based-security-incident-in-past-year-byod-saas-tools-and-remote-work-policies-all-play-a-part-in-security-resilience

M&S Chief’s Pay Slashed by £3M After Cyberattack Turmoil

The chief executive of UK retailer Marks & Spencer saw his pay fall by more than 40% after a major cyber attack disrupted the retailer’s operations and M&S cancelled its executive bonus scheme. The attack halted online services for weeks, affected card payments in some stores, and contributed to weaker financial performance, resulting in lower bonus and share-based awards for executives. M&S put the total cost at £133.3 million, although more than £100 million has been recovered through insurance.
