Anderlues Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Anderlues was listed by thegentlemen ransomware group on April 19, 2026, with internal files reported as exfiltrated. Individuals who may have been affected should check the organisation’s notifications and take protective steps.
On April 19, 2026, the ransomware group thegentlemen listed the municipality of Anderlues on its leak site, claiming to have obtained internal files during a ransomware attack. Anderlues.be serves as the official digital portal for the small Belgian town in Hainaut province, providing residents with access to local government services. The number of people affected and the precise volume of data remain undisclosed in public reporting.
Incidents involving local government systems have become a recurring feature of the ransomware threat landscape, where attackers target entities that maintain records on residents and deliver essential public services. When such an organization appears on a leak site, questions arise about the scope of any exfiltration and the potential downstream effects on the community it serves.
Breaking down the breach
The available information indicates that thegentlemen claims responsibility for a ransomware operation against Anderlues in which internal files were exfiltrated. No Reported Details have been released regarding the date of the intrusion, the method of initial access, the encryption of systems, or any ransom demand. The number of files or records involved has not been made public, and the municipality has not issued a statement confirming or disputing the listing.
Inside thegentlemen
Thegentlemen is a ransomware group that follows the common pattern of encrypting victim systems and listing organizations on a dedicated leak site when payment demands are not met. Such groups typically operate by gaining initial access through phishing, remote-desktop vulnerabilities, or compromised credentials, then moving laterally to locate and exfiltrate data before deploying encryption. Their listings serve as a form of pressure on victims, though independent verification of each claim is often limited at the time of publication.
About Anderlues
Anderlues is a municipality of roughly 12,000 residents covering 17 square kilometres in Wallonia, Belgium. Its website functions as the primary online interface for local administration, including an e-counter for official documents, announcements about cultural events, and information on services such as recycling, social assistance, and energy subsidies. Local governments of this scale routinely process personal data tied to residents’ interactions with public services, making them repositories of information that can include names, addresses, and administrative records.
The information in question
The only data type referenced in connection with the listing is internal files exfiltrated during the ransomware attack. No inventory of specific document categories or record counts has been disclosed. Municipalities in Belgium commonly hold citizen data related to tax records, social services, permits, and identity verification; however, whether any such categories were among the files referenced by the group remains unconfirmed.
What's at stake
For residents, exposure of internal municipal files could lead to misuse of personal identifiers or administrative details in fraud attempts or targeted scams. For the municipality itself, the incident may result in operational disruption, costs associated with investigation and system restoration, and potential regulatory scrutiny under Belgian and European data-protection rules. The absence of Reported Details on the data’s contents limits precise assessment of these risks at present.
Were you affected?
Individuals concerned about possible exposure can begin by monitoring their financial accounts and official correspondence for unusual activity. Contacting the municipality directly can provide the most current information on any notifications or remediation steps it may issue. Running a free exposure scan of one’s email address against known breach datasets offers an additional way to check whether personal information has appeared in previously published collections.

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.
