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.

What Public Reporting Shows

Public reporting indicates that Thompson Builders, a construction firm, was hit by a ransomware incident. The attackers claim to have stolen internal documents totaling more than three terabytes. No exact victim count has been released, and it remains unclear which specific categories of records were taken. The data has not yet been publicly dumped in full, but the group’s site displays proof files and continues to pressure the company with a deadline.

Available reporting describes the incident as a classic ransomware pattern: initial access, data theft, encryption of systems, and subsequent extortion demands. Industry trackers such as ransomware.live have mirrored the listing from the group’s onion site.

Why This Matters for You and Your Family

When a company like Thompson Builders suffers a breach, the information inside those files can easily include details about everyday people. Vendors, subcontractors, employees, and their families often have addresses, Social Security numbers, banking information, or tax records stored in construction project folders, payroll files, or vendor databases. Once exfiltrated, that data does not disappear.

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.
