Disclosure context

About beast

The Beast ransomware group is a relatively new threat actor that emerged in July 2025, operating with apparent financial motivations through their ransomware campaigns. With limited public documentation available from major security agencies, the group has demonstrated activity primarily targeting victims across the United States, United Kingdom, Brazil, South Korea, and Argentina, accumulating approximately 65 known victims since their emergence. Their targeting pattern shows a focus on healthcare organizations, manufacturing companies, educational institutions, and construction firms, suggesting an opportunistic approach rather than highly specialized sector expertise. The group's recent emergence means there is insufficient public intelligence from CISA, FBI, Mandiant, or other established security researchers regarding their specific attack methodologies, initial access vectors, or technical capabilities. Given the timeline of their first observation in mid-2025, Beast represents an active and emerging threat with their current operational status remaining unclear due to limited threat intelligence reporting from authoritative sources. The group has been linked to 104 public disclosures across our corpus. First observed on a leak site on July 29, 2025; most recent post June 11, 2026. The operation is currently active.

If your organisation is affected

A listing by beast means Jack's Lawn Service, Inc. 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.
  • Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
  • Monitor for the data appearing on beast'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.
