Le Perreux sur Marne Listed by thegentlemen Ransomware Group

On May 24, 2026, the municipal portal of Le Perreux-sur-Marne, a suburb of Paris, appeared on the leak site of the ransomware group known as thegentlemen. The French town’s official website, leperreux94.fr, provides residents with access to ID appointment booking, local event calendars, transport schedules, and social programs. Public reporting indicates that internal files were exfiltrated during a ransomware attack on the local government system.

What's Publicly Reported from Reporting

Available reporting describes the incident as a ransomware deployment that resulted in data exfiltration. The victim is the municipality of Le Perreux-sur-Marne, which operates the central citizen portal used by local residents for everyday government services. No precise count of affected individuals has been released, but any resident who has used the e-services portal may have personal information contained in the compromised internal files.

May 24, 2026 marks the date the data was listed on the group’s leak site. The exposed material consists of internal municipal documents rather than a simple database dump. Ransomware.live, which tracks such incidents, lists the entry under the group’s name with a direct link to the leak page.

Why This Matters for You and Your Family

When a local government portal is breached, the information exposed often includes names, addresses, dates of birth, contact details, and records tied to family services or children’s programs. If your family lives in or near Le Perreux-sur-Marne and has booked appointments, registered for events, or used any of the online municipal tools, your data may now sit in files controlled by attackers.

Even if you do not live in that specific suburb, the incident shows how everyday interactions with local authorities can create lasting digital records. These records are frequently targeted because they link real identities to addresses, phone numbers, and family members in ways that are difficult to untangle once stolen.

The Doxxing and Identity-Chain Risks

Stolen municipal files rarely stay isolated. Attackers can combine them with information from earlier breaches to build detailed profiles. A single address or phone number found in local government records can be cross-referenced with email addresses, usernames, or children’s activity on gaming platforms. This creates an identity chain that leads from official documents to personal accounts across the internet.

Credential leaks of this nature frequently cascade into account takeovers. Once attackers control even one of your accounts, they can reset passwords elsewhere, request additional personal data, or publish the information to increase pressure. Gaming accounts belonging to you or your children are especially vulnerable because they often share the same email or password patterns used for more official services.

Thegentlemen Group’s Known Track Record

Public reporting attributes the attack to the ransomware group thegentlemen. The group emerged in recent years and has targeted organizations across multiple countries with a consistent playbook: gain initial access, exfiltrate sensitive internal files, and then demand payment while threatening to publish the data on their leak site if the deadline is missed. Notable prior victims include other municipal and private-sector entities, though exact details vary by incident. Their typical approach relies on double extortion — encrypting systems where possible while simultaneously holding the stolen data for ransom.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, addresses, and online handles so you can see exactly what chains back to the Le Perreux-sur-Marne records.
• Rotate any password you have ever used on a municipal or local government site and enable two-factor authentication through an authenticator app on every account where that password was reused.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours rather than months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become the next link in doxxing chains after credential leaks like this one.
• Let remediation specialists handle takedown requests and broker removals for you while you focus on securing the accounts that matter most to your family.
