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.

If your organisation is affected

A listing by Killsecurity means Medswana appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Monitor for the data appearing on Killsecurity's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
