Comdat Datasystems Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Comdat Datasystems has been listed by thegentlemen ransomware group, with internal files confirmed as exfiltrated; the incident was reported on 15 February 2026. Anyone whose data may have been held by Comdat Datasystems should check the organisation’s notices and consider protective steps such as changing passwords and monitoring accounts.
Breaking down the breach
The only confirmed information is the listing itself and the group’s assertion that files were taken. No date of the intrusion, no count of records, and no description of the encryption or exfiltration methods have been disclosed. The company has not issued a public statement confirming or denying the claims at the time of reporting.
Who is thegentlemen?
Thegentlemen is a ransomware group that maintains a public leak site where it lists organisations it claims to have compromised. Like similar groups, it typically exfiltrates data before deploying encryption and then uses the threat of publication to pressure victims. Public records show the group has appeared in multiple incidents involving corporate networks, though independent confirmation of each listing varies.
Comdat Datasystems and its sector
Comdat Datasystems AG, based in Switzerland, provides ICT infrastructure solutions to businesses. Its services include the planning, implementation, and management of servers, storage, virtualisation, communication systems, collaboration tools, workplace environments, and printing infrastructure, along with managed services in communication technology. Organisations in this sector routinely hold configuration data, client network details, and internal operational records.
The information in question
The listing refers only to “internal files.” The precise categories of data have not been published. Companies of this type commonly maintain records related to client environments, system configurations, administrative credentials, and project documentation, but the exact contents of the exfiltrated material remain unconfirmed.
Why it matters
Exposure of internal infrastructure files can reveal details about client networks and security controls, which may be used in further attacks. For the organisation, the incident creates operational and reputational consequences even when the full scope of data remains unknown. Individuals whose information is held by Comdat Datasystems or its clients face potential downstream risks if those files contain personal or account-related data.

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.
