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 86 public disclosures across our corpus. First observed on a leak site on November 13, 2024; most recent post May 15, 2026. The operation is currently active.
