N0N Ransomware: 14 Unverified Claims in 24 Hours Target US Healthcare Sector
Analysis of public tracker data shows N0N made 14 unverified leak-site claims in a single day, outpacing other active ransomware affiliates significantly.

Key points
- N0N accounted for 14 of the 23 total ransomware leak-site claims recorded in a 24-hour period.
- The United States was the most targeted country, with 10 claims, followed by Canada with two.
- The healthcare sector faced the highest number of claims, with four incidents reported in this window.
Our data desk analysis of public information from ransomware.live reveals that 23 ransomware leak-site claims occurred within a 24-hour period. The N0N group was the most active actor, responsible for 14 of these unverified statements. Other groups included qilin with three claims, rhysida with two, and single claims from emperador, BrainCipher, dragonforce, and incransom. Victim names are deliberately omitted from this report to avoid amplifying criminal propaganda or causing unnecessary distress to affected organisations.
Root cause
The source material does not specify technical root causes, software vulnerabilities, or initial access vectors for these incidents. These figures represent unverified statements made by criminal groups on their leak sites, rather than confirmed security breaches or technical failures. The data reflects the volume of public assertions by threat actors, not an analysis of how specific systems were compromised or what software flaws were exploited.
Attack path
No specific attack paths, tactics, techniques, or procedures are detailed in this dataset. The information provided is limited to the count of claims by group, country, and sector. It does not describe how the N0N group or other affiliates gained access to victim networks, nor does it outline the methods used to exfiltrate data or deploy ransomware. The focus remains on the frequency of public leak-site announcements.
Affected versions
This report does not identify specific software versions, operating systems, or applications that were affected by these ransomware claims. The data categorises incidents by geographic location and industry sector rather than technical environment. Consequently, no version strings or patch levels can be derived from this tracker analysis.
Mitigation
The source material does not provide specific mitigation steps, patches, or configuration changes for these incidents. As these are unverified leak-site claims, no technical remediation is detailed. General security hygiene and incident response planning remain the standard approach for organisations facing such threats, but no specific fixes are mentioned in this dataset.
What to do and how to stay safe: N0N
- Monitor official vendor advisories and threat intelligence feeds for confirmed details on active ransomware campaigns.
- Verify the integrity of critical systems and backups regularly to ensure recovery capabilities remain robust.
- Review access logs and network traffic for anomalies that might indicate unauthorized data exfiltration.
- Ensure incident response plans are up to date and staff are trained on communication protocols during a crisis.
