Check Ransomware Leak Sites: N0N Group Files 14 Claims in Single Day

Our data desk analysis of public tracking data reveals that ransomware operators filed 23 leak-site claims within a single 24-hour period. The N0N group was the most active actor during this window, responsible for 14 of those claims. Other groups including Qilin, Rhysida, Emperador, BrainCipher, DragonForce and IncRansom also filed claims, though their numbers were significantly lower. These figures represent unverified statements made by criminal groups on their public leak sites.

Which ransomware groups were most active?

According to the ransomware.live tracker, the N0N group was the most active with 14 distinct claims. Qilin followed with three claims, while Rhysida filed two. Single claims were attributed to Emperador, BrainCipher, DragonForce and IncRansom. This distribution shows the activity levels of different threat actors during this specific timeframe. Our data desk counted these entries to determine relative activity levels across different groups based on the source material.

Where are the targeted organisations located?

The United States faced the highest number of claims, with 10 organisations targeted in this 24-hour cycle. Canada followed with two claims, while Australia, Morocco, Peru and Colombia each had one claim recorded. The data lists these countries based on the location of the organisations claimed by the ransomware groups. The source material provides this geographic breakdown without further commentary on the distribution or intent of the attackers.

Which sectors are being targeted?

Healthcare organisations were the most frequently targeted sector, with four claims filed against them. Professional services and technology sectors each saw two claims. Transportation and government and defence sectors each had one claim recorded. The source material categorises these claims by sector to provide a clear view of which industries were mentioned in the leak-site posts during this period.

What do these claims mean for victims?

These claims are unverified statements made by criminal groups on their leak sites. They indicate that the groups believe they have exfiltrated data or disrupted operations, but independent verification is often difficult. Victim names are deliberately not reported in this analysis to protect the privacy and security of affected organisations. The presence of a claim on a leak site is a serious indicator of potential compromise, but it does not confirm the extent of data loss or system damage.

What to do and how to stay safe: N0N ransomware

• Monitor official security advisories and threat intelligence feeds for updates on active ransomware groups.
• Ensure that critical data is backed up to offline or immutable storage systems that cannot be modified by attackers.
• Verify the integrity of systems and logs regularly to detect any signs of unauthorised access or data exfiltration.
• Once the vendor provides an update, apply security patches promptly to known vulnerabilities in your infrastructure.
