On February 07, 2024, Swiss company Bucher-Strauß AG appeared on the LockBit 3.0 ransomware leak site with 140 gigabytes of internal files listed for public download. The listing indicates that the firm, which operates in the construction and real-estate sector, suffered a ransomware attack in which data was exfiltrated before encryption. Anyone whose personal or employment records were stored with the company may now be exposed.
Already exposed?
You can’t unleak data. You can take away what it’s worth.
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.

Reported Details from the Leak Site
The LockBit 3.0 portal states that attackers stole 140 GB of internal files during a ransomware operation. The disclosure does not specify the exact types of records taken, nor does it list the number of affected individuals. It simply states that data was exfiltrated and is now hosted for anyone to download. The notification also sets an implicit deadline typical of the group: if no ransom is paid, the files will remain freely available or be released in batches.
Why This Matters for You and Your Family
When a construction or property-management firm loses control of internal files, the information often includes contracts, invoices, employee payroll data, tenant records, banking details, and correspondence that contain names, addresses, dates of birth, and financial references. Even if the leak site does not quantify affected records, the volume alone—140 gigabytes—suggests thousands of documents that can be pieced together by identity thieves. For ordinary people, this translates into heightened risk of account takeover, loan fraud, or targeted phishing using details only your employer or landlord should possess.
The Doxxing and Identity-Chain Risk
Leaked internal files frequently contain spreadsheets that link personal email addresses, phone numbers, home addresses, and sometimes family-member references. Once these appear on a ransomware portal, other criminals scrape them and begin building identity chains. A single leaked work document can connect your corporate login to personal accounts, gaming profiles, or children’s school records. Credential leaks of this nature routinely cascade into account takeovers, especially for gaming platforms where kids reuse passwords. The longer the data sits in the open, the more likely it is to fuel doxxing campaigns or SIM-swapping attempts against you or members of your household.
