Disclosure context

About Kairos

Kairos is a recently emerged ransomware group first observed in November 2024 that appears to be primarily financially motivated, having targeted approximately 75 victims across multiple sectors and countries. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, and it is unknown whether they operate as a Ransomware-as-a-Service model or as an independent entity. Based on available targeting data, Kairos appears to focus their operations primarily on English-speaking countries including the United States, Australia, United Kingdom, and Canada, with additional activity observed in Germany, while their sector targeting spans education, healthcare, agriculture and food production, and business services, though specific attack methodologies, initial access vectors, and encryption techniques have not been publicly documented by major security organizations. Given the group's recent emergence in late 2024, there are no widely reported notable campaigns or high-profile incidents documented by CISA, FBI, or established security research firms. As of current reporting, Kairos appears to remain active based on their recent first observation date, though comprehensive threat intelligence profiles from major security organizations have not yet been published due to the group's nascent operational timeline. The group has been linked to 88 public disclosures across our corpus. First observed on a leak site on November 13, 2024; most recent post June 1, 2026. The operation is currently active.

If your organisation is affected

A listing by Kairos means mortensenlawoffices.com/USA/99GB 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 Kairos's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
