What Happened

• Throughout H1 2026, the Qilin ransomware-as-a-service (RaaS) Tor data leak site (DLS) listed the most UK-based victims out of all ransomware gangs, with up to 37 British organisations hit in total. Qilin's victim count is followed by DragonForce with 21 victims listed, and TheGentlemen with 18 listed.
• The fallout from the Qilin attack on the UK National Health Service (NHS) supplier, Synnovis, in 2024 persists as well. On 1 June 2026, the Bedfordshire Hospitals NHS Foundation Trust disclosed that over 32,000 patient data records related to Synnovis tests were exfiltrated and took over a year to analyse what information was related to which patient. The breached data includes patient name and number, date of birth, postcode, and test results.
• In H1 2026, Qilin averaged between seven and nine published UK victims per month. For the entries listing an estimated attack date, there was a roughly six-week extortion lifecycle on average, from initial intrusion to the date the victim is publicly named.
• This UK footprint highlights their aggressive pursuit of Small-to-Medium Enterprises (SMEs) as most organisations had a revenue between £10m and £250m.
• Interestingly, one of the Qilin victims, Salford City College, also appeared on both the Qilin and DragonForce Tor data leak site (DLS) only a few days apart from 6 March to 10 March 2026, respectively.

Analyst Comment 

Many of the organisations targeted by Qilin operators are just large enough to have the funds to pay mid-tier ransoms but often never got around to making an investment into a 24/7 dedicated threat detection service, such as an outsourced Security Operations Centre (SOC). Such services are usually enough protection to prevent an attack. If a ransomware affiliate faces tough resistance from a target, they often move on to a weaker and easier one.

One key face to also note about Tor data leak sites operated by ransomware groups is that they include victims who failed to pay the ransom. The total number of victims by each group is often going to be higher.

The reason for the cross-posting of Salford City College is unknown for now. However, it could indicate that an affiliate may be using both Qilin and DragonForce RaaS platforms. An alternative theory could be that the college was hit by two affiliates of each RaaS. Interestingly, cross-posting on multiple leak sites is not as uncommon as it seems. Some victims listed on the Qilin leak site have historically appeared on the leak sites of ALPHV/BlackCat and Conti as well.

The Ransomware Vulnerability Matrix Group Profile for Qilin reveals a diverse set of exploits leveraged by its operators. Like many other ransomware gangs, Qilin operators have exploited corporate VPN gateways such as Fortinet, Check Point, and WatchGuard for initial access. Interestingly, the exploitation of SmarterTools SmarterMail and SolarWinds Web Help Desk is less common but are also exploited by the Warlock ransomware gang. Another common theme from Qilin's Ransomware Tool Matrix Group Profile is their regular abuse of Bring Your Own Vulnerable Driver (BYOVD) tactics to bypass Endpoint Detection and Response (EDR) and Antivirus software.

Defensive Takeaways 

• Harden Common Attack Paths: Treat any web-facing helpdesk or mail server as a high-risk device. If it does not absolutely require open internet access, place it behind a zero-trust network access gateway or a strict VPN. Enforce strict phishing-resistant Multi-Factor Authentication (MFA) on all remote access points. Ensure processes are in place for rapid patching and integrity checks for all corporate VPN gateways.
• Overcoming SME Resource Caps: Organisations must bridge the gap with an outsourced MDR service. Ransomware execution routinely happens at 2:00 AM on Fridays and weekends. Outdated antivirus agents alone are not enough to stop a motivated human adversary.
• Utilise Free Support Services: Capitalise on sovereign and community-vetted threat intelligence feeds to block attacker infrastructure early. UK defenders should actively enroll in the National Cyber Security Centre’s MyNCSC portal and integrate community resources like the Spamhaus DROP list and Abuse.ch tracking into their perimeter firewalls to automatically block known ransomware command-and-control (C2) nodes. ShadowServer and Team Cymru also offer useful free community resources.

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 exit scams and law enforcement infiltration operations have created a zero trust environment for the cybercriminals participating in the ransomware economy. The days of affiliates putting their faith in one RaaS platform seem to be long gone and many are experimenting and going from one RaaS to the next.

Sources of Threat Intelligence for the RTM

The RTM was updated with OSINT reports shared by cybersecurity researchers at various private service providers or vendors. The thing to remember about these reports is that the tool usage is going to be slightly outdated due to the time it takes incident response teams to wrap up an investigation, compile findings, and publish a report.

From the reports, threat groups such as Qilin, BlackSuit, RansomEXX, Medusa, BianLian, Hunters International and PLAY have been active for over one year or for multiple years. These are established groups. Since RansomHub and LockBit have shut down, it is more likely than not that the affiliates have already shifted to one of the other RaaS platforms, like Qilin, among others.

There has also been a number of ransomware operations suspected to be linked to Chinese cyber-espionage groups, such as RA World (for using PlugX), NailaoLocker (for using ShadowPad and PlugX), and CrazyHunter (for its focus on Taiwan).

Threat groups such as IMN Crew, QWCrypt (linked to RedCurl), NightSpire, SuperBlack, and Helldown are all rising threat groups that have more recently begun their ransomware campaigns.

These factors have led to seeing a large variety of tool usage in ransomware operations being observed across the landscape. The reliance on tools from sites like GitHub and other free software sites, however, continues to remain a constant theme among all of these ransomware operations.

List of sources used for the May 2025 major update to the RTM:

Tools Used by Multiple Groups

• EDRSandBlast and WKTools are relatively new tools that are being used by multiple groups to deactivate and overcome EDR tools that many victims will have on their networks to prevent ransomware attacks.
• Typical ransomware tools, such as PsExec, Mimikatz, and Rclone remain effective and still used by multiple ransomware gangs for the foreseeable future.

New Tools Added to the RTM

• The most notable new tools added to RTM include several defense evasion tools for deactivating EDRs, discovery for sensitive files, and tunnelling tools to conceal adversary network connections.

Exploits used by Ransomware Gangs added to the RVM

• As is now usual, multiple ransomware groups have been targeting Fortinet networking devices for initial access into to victim environments.
• Multiple ransomware groups continue to exploit the Windows Common Log File System (CLFS) for local privilege escalation to run hacking tools and steal credentials.
• Other exploits involve targeting edge devices, such as Check Point VPNs or PAN Firewalls, or exposed servers, such as Atlassian Confluence Data Center Servers.
• The targeting of Veeam backup software should come as no surprise as preventing backups or stealing sensitive files, such as Active Directory backups, are key objectives of ransomware gangs to complete their mission.

Conclusion

My recommendation for defenders who continue the fight against ransomware is to take some of the findings from this report and begin threat hunting, detection rule writing, and start blocking some of these tools not present in the environments you are protecting.
