Disclosure context

About krybit

Krybit is an emerging ransomware group that was first observed in April 2026, operating with apparent financial motivations based on their limited documented attacks against diverse sectors. The group's origin and affiliations remain unclear due to limited public intelligence, and it is unknown whether they operate as a Ransomware-as-a-Service model or as an independent entity. With only four known victims documented across geographically diverse regions including Mexico, Austria, Japan, and Botswana, the group appears to employ broad targeting rather than focused regional or sector-specific campaigns, though their attack methodology, encryption techniques, and data exfiltration practices have not been publicly documented by major security firms or law enforcement agencies. No notable high-profile campaigns or significant ransoms have been publicly reported, and no law enforcement actions against the group have been documented. Given the recent emergence of this group and extremely limited public reporting, Krybit's current operational status and capabilities remain largely unknown to the broader cybersecurity community. The group has been linked to 31 public disclosures across our corpus. First observed on a leak site on April 3, 2026; most recent post May 19, 2026. The operation is currently active.
