Inside the incident
The incident came to light through the group’s listing on April 08, 2026. Public information is limited to the claim that internal files were taken. No confirmed timeline for the intrusion, the method of access, or the scale of the operation has been released by the company or investigators.
The group behind it: thegentlemen

The information in question

Publicly posted by thegentlemen — 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.
