Who is incransom?
Incransom is a ransomware operation that publishes victim names on a leak site when negotiations fail or to apply pressure. The group typically claims to have exfiltrated data before encryption and lists selected files or descriptions to support those claims. Its listings are presented by the group itself and are not independently verified at the time of publication.

Publicly posted by incransom — 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.
