Anderlues Listed by The Gentlemen Ransomware Group

If you are a customer of Anderlues, here’s what is being claimed, and what it would mean for you.

Anderlues.be is the official website of the municipality of Anderlues, a small town in the province of Hainaut, Wallonia, Belgium, with a population of approximately 12,000 residents and an area of 17 km². The site serves as the main digital portal for local government services, including an e-counter (E-Guichet) for requesting official documents online, news and announcements, cultural events, and public infrastructure services. The municipality is governed by a local council and offers residents services such as recycling centres, social assistance, energy subsidies, and cultural programmes
— from The Gentlemen’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

Anderlues Listed by The Gentlemen Ransomware Group

On April 8, 2026, the Belgian municipality of Anderlues appeared on the leak site of the ransomware group known as thegentlemen. The attackers claim to have exfiltrated internal files from the town’s official website and digital services, which serve roughly 12,000 residents in the province of Hainaut, Wallonia.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that Anderlues.be functions as the central online portal for local government services, including the E-Guichet system residents use to request official documents. The site also hosts news, cultural event listings, and information about recycling centres, social assistance, energy subsidies, and public infrastructure. Available reporting describes the incident as a ransomware attack in which internal files were taken; the exact volume and specific types of data remain unconfirmed by the municipality at the time of writing. The listing appeared on the group’s leak site with a deadline for payment, after which files would be published or sold.

Why This Matters for You and Your Family

When a local government portal is breached, the information at risk often includes names, addresses, dates of birth, national identification numbers, and copies of official documents that ordinary families rely on every day. If you or your family live in Anderlues or have used the E-Guichet service in recent years, your personal records may now sit in an attacker’s archive. Even when victim counts are listed as unknown, the exposure of municipal systems frequently cascades to residents who submitted data through those exact portals. One breach can give criminals the starting point they need to target your household with phishing, identity theft, or physical scams that feel very personal.

The Doxxing and Identity-Chain Implications

Municipal data rarely stays isolated. Addresses, phone numbers, and family member names can be combined with credentials stolen from other breaches to map entire households. Public reporting shows that attackers increasingly chain these records together: an email from one leak links to a gaming username, which links to a child’s account, which reveals additional personal details. This creates a doxxing chain that can lead to harassment, spear-phishing campaigns, or extortion attempts against parents and children alike. Credential leaks like this one regularly cascade into account takeovers on gaming platforms, social media, and email services used by families.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
