Disclosure context

About Killsecurity

Killsecurity is a relatively new ransomware group that emerged in March 2024, operating with apparent financial motivations and demonstrating rapid expansion in their victim targeting. The group's origin and affiliations remain unclear due to limited public documentation from major threat intelligence sources, though their global targeting pattern suggests a sophisticated operation. Based on available victim data, Killsecurity has compromised 276 organizations primarily across the United States, India, United Kingdom, Brazil, and Belgium, with a particular focus on healthcare, technology, business services, and financial sectors. The group's attack methodology, encryption techniques, and specific tools remain undocumented in public threat intelligence reports from established security firms. Notable campaigns and high-profile victims have not been extensively documented by major cybersecurity organizations or law enforcement agencies, likely due to the group's recent emergence. Killsecurity appears to remain active as of current reporting, though comprehensive analysis of their operations is limited by the lack of detailed technical documentation from reputable threat intelligence sources. The group has been linked to 277 public disclosures across our corpus. First observed on a leak site on March 21, 2024; most recent post May 15, 2026. The operation is currently active.

Attack summary

Severity: medium — Data has been marked as published, indicating some level of exfiltration or disclosure has occurred; however, the leak post is extremely sparse with no stated data volume, no ransom, no enumerated data types, and no proof file count, limiting the ability to confirm regulated or sensitive data exposure at scale.

Killsecurity claims to have compromised X-CD Technologies and has published data (disclosed_status: data_published), though the leak post provides minimal detail on whether encryption or exfiltration occurred and specifies no ransom amount or data volume.
