Le Perreux sur Marne Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Le Perreux sur Marne was listed by thegentlemen ransomware group on May 24, 2026, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may be affected; check the organisation’s notices and monitor accounts for any unusual activity.
Inside the incident
The incident centers on the municipal website that provides residents with access to local government services. The group’s listing indicates that files were removed from the system, yet no technical details about the intrusion method, the duration of access, or the encryption status of systems have been made public. The date of the actual compromise remains undisclosed, and the municipality has not issued a separate statement confirming or contesting the claim.
Who is thegentlemen?
Thegentlemen is a ransomware operation that maintains a leak site where it lists organizations it claims to have targeted. Like other groups in this category, it typically combines file encryption with the threat of data publication to pressure victims. Public records show the group has previously listed entities across multiple countries, though independent verification of each claim is not always available. In this case the listing itself constitutes the group’s assertion that Le Perreux sur Marne was successfully attacked.
Le Perreux sur Marne and its sector
Le Perreux sur Marne is a commune in the eastern suburbs of Paris that maintains an online portal for citizen services. Such municipal sites commonly manage appointment systems, local directories, and administrative records. Because they handle interactions between residents and local government, they routinely process identifying information and service-related data. A compromise at this level can affect routine administrative functions as well as any personal details stored in connected systems.
What was likely exposed
The only detail released is that internal files were allegedly exfiltrated. The exact categories of information contained in those files have not been disclosed. Municipal portals of this type typically store records related to resident registrations, service requests, and internal correspondence, but it is not confirmed whether any of those categories were among the files removed. Until a more detailed inventory is published, the scope of personal or operational data remains unverified.
The real-world impact
Residents may face risks if the exfiltrated files contain personal identifiers or service histories that could be used for identity-related fraud or targeted scams. For the municipality, the incident may require extended forensic review, possible service interruptions, and costs associated with restoring systems and notifying affected parties. The absence of confirmed data volumes makes it difficult to assess the full extent of these consequences at present.

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.
