Disclosure context

About cmdorganization

Based on the limited available information, cmdorganization is an obscure ransomware group first observed in May 2026 with only three documented victims to date, suggesting either a newly emerged threat actor or a small-scale operation with primarily financial motivations. The group's targeting pattern shows a geographic focus on Canada, the United States, and Italy, with a sectoral preference for healthcare and construction industries, though the limited victim count makes it difficult to establish definitive targeting criteria. Due to the recent emergence and low victim count, there is insufficient publicly documented information from major cybersecurity firms or law enforcement agencies regarding their specific attack methodologies, encryption techniques, or operational structure. No notable high-profile campaigns or significant ransoms have been publicly reported for this group, likely due to their limited operational scope and recent emergence. Current intelligence suggests the group remains active but operates at a relatively small scale compared to established ransomware families. The group has been linked to 36 public disclosures across our corpus. First observed on a leak site on May 2, 2026; most recent post July 14, 2026. The operation is currently active.

If your organisation is affected

A listing by cmdorganization means Stonehenge Therapeutic Community 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, NCSC (United Kingdom), as required for your jurisdiction.
  • Monitor for the data appearing on cmdorganization'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.
