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 of the Breach

Public reporting indicates the company, which operates wholesale and retail warehouses supplying food, beverages, fresh and dry goods across Romania, had its internal files taken during a ransomware incident. The Blacknevas leak page lists the full directory of stolen material and offers samples upon request via the file-sharing service Gofile. The group states it is actively contacting the company’s partners, friends, and clients to negotiate the purchase of the data. Available reporting describes the listing as still active with no confirmed evidence of mass publication at the time of writing.

Why This Matters for You and Your Family

When a supplier or service provider you use suffers a breach, your personal information often travels with it. Purchase records, delivery addresses, phone numbers, email accounts, and payment details stored in supplier databases can surface in ransomware leaks. For ordinary families this means heightened risk of identity theft, targeted phishing, and unwanted solicitations. 243 GB is a substantial volume; even a fraction of that cache can contain spreadsheets linking customer names to contact information and transaction histories. Once such data leaves the company’s control, it circulates indefinitely on dark-web forums and can be resold for years.

The Doxxing and Identity-Chain Risks

Ransomware leaks rarely stop at one company. Criminals map relationships between suppliers, customers, and employees, then follow the chains to additional victims. A delivery address tied to your name can be cross-referenced with social-media handles, children’s school accounts, or gaming usernames. These connections allow attackers to build detailed profiles that lead to doxxing, account takeovers, or extortion attempts. Credential leaks of this nature frequently cascade into gaming platforms, where children’s accounts become entry points for further compromise because the same email or password is reused across services.

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.
