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 sinobi listed Eco Sound Builders, LLC, a custom home builder specializing in sustainable and net-zero construction. The company’s data was allegedly stolen and is now hosted on the group’s onion site. No exact victim count has been disclosed, and the precise volume or sensitivity of the files remains unclear from available reporting. The listing follows the typical ransomware pattern of initial encryption, exfiltration, and subsequent public shaming when ransom demands go unmet.

Internal files were taken; the types of records have not been itemized in public summaries. The incident aligns with hundreds of similar cases tracked on ransomware.live, where construction and service firms frequently appear because their operational documents often contain customer contracts, payment details, and employee information.

Why This Matters for You and Your Family

When a local builder like Eco Sound Builders suffers a breach, your family’s personal information may be exposed. Homeowners who worked with the company could find addresses, phone numbers, email accounts, payment records, or renovation plans now sitting in an attacker’s archive. That data can be sold, swapped, or used to launch targeted follow-on attacks against you.

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.
