UK Cybercrime Journal: Sustained DragonForce Campaign

Image
  What Happened Throughout May 2026, affiliates of the DragonForce ransomware-as-a-service (RaaS) platform claimed seven UK-based companies as its victims by posting them on their Tor data leak site. On 27 May 2026 alone, DragonForce ended the month by posting 22 victims from around the world, four of which were UK-based firms. DragonForce’s UK-based victims from May spanned a diverse range of industries: Professional Services & Talent:  Practicus (interim management/executive search) Financial & Tax Services:  WSM (UK tax advisory) Infrastructure & Logistics:  ERH (traffic management solutions) and Refreshment Systems (vending/logistics) Heavy Industry/Construction:  Arsenal Scaffold Technology & IT:  Helix International (managed enterprise software) Luxury Retail/Finance:  Cult Wines. Analyst Comment Active since late 2023, DragonForce remains a persistent cybercriminal threat particularly towards the UK. The recent flurry of disclosu...

Ransomware Tool Matrix Project Updates: Three Groups To Track

Image
  Introduction This blog is a focused update on the latest updates to the  Ransomware Tool Matrix (RTM)  and the  Ransomware Vulnerability Matrix (RVM)  covering three groups that I have published profiles for to help defenders home in on the threats most relevant to them: TheGentlemen, DragonForce, and WarLock. Rather than write another broad ecosystem summary, the goal of this post is to introduce these profiles, briefly explain why each group matters right now, and give readers direct links to them so defenders can pivot straight into hunting, detection engineering, and patch prioritisation. For anyone new to the projects, please read the descriptions on GitHub or feel free to watch my talk explaining the project at  BSides London . Why these three groups? Each of the three groups added in this update represents a different slice of the current ransomware ecosystem: TheGentlemen TheGentlemen is a newer operation that has matured quickly, with a large and...

UK Cybercrime Journal: Inside the Cl0p attack on South Staffs Water

Image
  What Happened: On 11 May 2026, the UK Information Commissioner’s Office (ICO) fined South Staffordshire Water £963,900 after the Cl0p ransomware group lurked completely undetected in its network for nearly two years. Initial access reportedly occurred via a malicious phishing email in September 2020, which downloaded Cl0p’s Get2Loader malware and their SDBBOT backdoor to establish persistence. The breach itself, however, was only discovered two years later in July 2022 when staff began investigating IT performance slowdowns and  ultimately found out that 4.1 terabytes of data was exfiltrated and the personal data of 633,887 customers and employees being published in August 2022 on Cl0p’s Tor data leak site. The ICO’s investigation also revealed a staggering list of systemic failures, such as  South Staff’s outsourced Security Operations Center (SOC) was blind to 95% of the network and that they conducted zero internal or external vulnerability scans over an 18-month win...

Ransomware Tool Matrix Update: Community Reports

Image
  Introduction The Ransomware Tool Matrix continues to be a useful passion project that I am happy to continue maintaining. One piece of common feedback I've received for the Ransomware Tool Matrix was that individuals would like to contribute their observations to it, but do not have public links they can cite (such as a formal blog post on a company website). Therefore, I came up with a plan to make a reporting template to help with this. What are Community Reports? Individuals can now share what tools they have seen various ransomware groups, affiliates, or initial access brokers (IABs) use via the new Community Report Template. The level of detail provided is the contributor's choice. The more verifiable information shared, the increased level of reliability and credibility. You can view the current list of Community Reports on GitHub  here . Why the need for Community Reports? Most of the sources of CTI about ransomware TTPs comes from open source reports by organisation...

Ransomware Tool Matrix Project Updates: May 2025

Image
Introduction This blog is a summary and analysis of recent additions to the Ransomware Tool Matrix (RTM) as well as the Ransomware Vulnerability Matrix (RVM) .  Feedback from the infosec community about these projects has been overwhelmingly positive and many researchers have contacted me to tell me how helpful they have found these to be.  It makes me happy to hear how doing something in my spare time can help stop ransomware attacks and cybercriminals from exploiting our society’s systems. And it is for that reason, I shall continue to maintain these projects as long as ransomware is still around.  For anyone new to these projects, please read the descriptions on GitHub or feel free to watch my talk explaining the project at BSides London . Background on the current ransomware ecosystem as of May 2025 Following the impact of Operation Cronos against LockBit and the exit scam by ALPHV/BlackCat, the ransomware ecosystem has been even more unstable than usual.  The e...
