Disclosure context

About insomnia

Based on the limited publicly available information, Insomnia is a relatively new ransomware group that first emerged in February 2026, appearing to be financially motivated based on their targeting patterns and operational behavior. The group's country of origin and potential affiliations with other ransomware operations remain unknown, with insufficient public documentation from major threat intelligence sources to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. Their attack methodology and specific technical capabilities have not been extensively documented by CISA, FBI, or major security research firms, though their targeting of 29 known victims across healthcare, technology, manufacturing, and hospitality sectors in the United States, Singapore, and Brazil suggests a broad opportunistic approach rather than highly selective operations. Given the group's recent emergence and limited public reporting from established threat intelligence sources, there are no widely documented notable campaigns or high-profile incidents that have garnered significant attention from law enforcement or major security vendors. As of current reporting, the operational status of Insomnia remains unclear due to the lack of comprehensive public analysis from authoritative sources, making it difficult to assess whether the group remains active or has ceased operations. The group has been linked to 44 public disclosures across our corpus. First observed on a leak site on February 7, 2026; most recent post August 19, 2026. The operation is currently active.

If your organisation is affected

A listing by insomnia means Aurora Health Management 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 insomnia'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.
