On June 30, 2025, Belgian construction company De Noordboom appeared on the leak site of the beast ransomware group. Public reporting indicates the attackers exfiltrated internal files during a ransomware incident. While the exact number of people whose personal information may be exposed remains unknown, anyone whose data was held by the company — customers, suppliers, employees, or their families — could now be at risk.

What Public Reporting Shows
The beast ransomware group posted a card for De Noordboom on its dark-web leak site, accessible via the .onion link tracked by ransomware.live. Available reporting describes the exposed material as internal files exfiltrated in a ransomware attack. No precise count of affected records or specific data types such as names, addresses, financial details or contact information has been publicly detailed. The company, which provides carpentry, groundwork, foundation, drainage, and masonry services, maintains project records that routinely include personal and household information for clients across Belgium.
Why This Matters for You and Your Family
When a local business like a construction firm suffers a breach, the consequences reach far beyond the company. Your home address, phone number, email, payment records, or even details about your children’s rooms or family schedules may have been stored in project files. Once that information leaves secure systems, it can be sold, traded, or used to target you with phishing, identity theft, or physical scams. Ordinary families who hired the firm for renovations or new builds now face the same exposure that large corporations insure against. The breach highlights how even straightforward home-improvement contracts can place your family’s personal data in harm’s way.
The Doxxing and Identity-Chain Implications
Leaked internal files often contain more than isolated records. They can link your email address to your physical home address, phone number, spouse’s name, and sometimes children’s details. Attackers chain these fragments together with data from earlier breaches, gaming accounts, or social-media handles. A single credential leak from this incident can cascade into account takeovers across email, banking, or online gaming platforms. DoxxScan by GalaxyWarden is designed for exactly these scenarios. Its continuous monitoring across 13.1B+ breach records and 100+ platforms, combined with AI-powered identity-chain mapping, helps connect the dots before criminals do. The service also provides hands-on remediation by specialists and household coverage that includes your children’s gaming accounts, which are frequent targets when personal data leaks.
