On July 15, 2025, German real estate firm Mausolff Immobilien appeared on the leak site of the dragonforce ransomware group. The attackers claim to have exfiltrated internal files during a ransomware incident. While the exact number of people whose personal information may be exposed remains unknown, anyone who bought, sold, rented, or inquired about property through the Moers-based agency could be affected.

What Public Reporting Shows
Public reporting indicates that dragonforce added Mausolff Immobilien to its data-leak blog on July 15, 2025. The firm, which specialises in residential and commercial real estate in the Moers region, has operated for more than 35 years. The ransomware operators state they obtained internal documents but have not yet published samples. No confirmed count of affected records has been released, and the precise systems breached have not been detailed in available reporting.
Why This Matters for You and Your Family
When a real estate agency is hit, the data exposed often includes names, addresses, phone numbers, email accounts, identity documents, bank details, and correspondence about property transactions. These records can reveal exactly where you live, how much you paid for your home, and who else lives with you. For families, that information creates a direct map to your front door and daily routines. Children’s names sometimes appear in tenancy or school-proximity records, turning a corporate breach into a household privacy problem.
The Doxxing and Identity-Chain Risk
Stolen real estate files rarely stay isolated. Attackers combine them with credential leaks from other services to build detailed profiles. A home address linked to an email address can reveal social-media accounts, gaming usernames, and family relationships. Once these links exist, doxxing escalates quickly: harassment, identity theft, or targeted scams become simpler. Credential leaks like this one cascade into account takeovers across email, banking, and gaming platforms that share similar passwords.
