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 Medusa exfiltrated internal documents from the San Antonio-based firm, which operates multiple offices across Central and South Texas and employs more than 550 sales agents. The corporate headquarters sits at 18756 Stone Oak Pkwy Ste 102, San Antonio, Texas, 78258. Available reporting describes the exposed material as internal files; the precise mix of customer records, contracts, employee information, or financial data has not been independently verified by third parties. The total volume released so far stands at 133.30 GB.

The incident follows the group’s standard pattern of encrypting victim systems, exfiltrating selected data beforehand, and then pressuring payment by threatening to publish the stolen information on its dark-web leak portal.

Why This Matters for You and Your Family

If you bought or sold a home through Coldwell Banker D’Ann Harper, REALTORS in the past several years, your personal information may now sit in a ransomware repository. Real estate transactions routinely contain full names, addresses, phone numbers, email addresses, dates of birth, Social Security numbers, bank account details, and copies of driver’s licenses or passports. Once that information reaches a public leak site, it becomes inexpensive raw material for identity thieves, loan fraudsters, and stalkers.

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.
