Disclosure context

About Termite

Termite is a recently emerged ransomware group that first appeared in November 2024, operating with apparent financial motivations based on their targeting patterns across multiple high-value sectors. The group's origin and affiliations remain largely undocumented by major threat intelligence providers, though their targeting of primarily Western nations including the United States, France, United Kingdom, Germany, and Canada suggests a non-Western operational base. With 39 documented victims across healthcare, telecommunications, business services, and technology sectors within just a few months of operation, Termite demonstrates an aggressive deployment strategy, though specific details regarding their initial access vectors, encryption methodologies, and whether they employ double or triple extortion tactics have not been publicly documented by established security research organizations. The group's relatively recent emergence means that notable high-profile campaigns and specific technical indicators have not yet been extensively analyzed or reported by authoritative sources such as CISA, FBI, or major cybersecurity firms. Termite appears to remain active as of early 2025, though the limited public documentation suggests they may be a smaller-scale operation or have not yet attracted significant attention from major threat intelligence organizations. The group has been linked to 48 public disclosures across our corpus. First observed on a leak site on November 17, 2024; most recent post June 9, 2026. The operation is currently active.

If your organisation is affected

A listing by Termite means Insight Hospital & Medical Center Chicago 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 Termite's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
