Who is akira?
Akira is a ransomware operation that has conducted multiple attacks on organizations since 2023. The group typically uses encryption to disrupt operations and exfiltrates data for additional leverage, posting claims on a dedicated leak site when victims do not meet its demands. Its listings describe stolen material in general terms and often include categories such as employee records and financial documents. Attribution in any single case rests on the group’s own statements unless corroborated by the victim or investigators.

Publicly posted by akira — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
