On September 4, 2025, the Austrian electrical installation company elektro-buder.at appeared on the leak site of the lynx Ransomware Group, with internal files reportedly exfiltrated during a ransomware attack.

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 the company’s data was listed on the lynx leak site hosted at an onion address. The listing includes internal files that were taken before the ransomware was deployed. No confirmed victim count has been published, and the precise volume or sensitivity of the files remains unclear from available reporting. The incident follows the group’s typical pattern of exfiltrating data then threatening public release unless a ransom is paid.

September 4, 2025 marks the public listing date. The exposed material consists of internal files rather than a structured database of customer records, though such files frequently contain names, addresses, contact details, project information, and employee data in companies of this type.

Why This Matters for You and Your Family

When a local business like an electrical contractor suffers a breach, the people affected are usually its customers and nearby residents. If you or your family have hired elektro-buder.at for home wiring, renovations, inspections, or emergency repairs, your personal information may sit inside the stolen files. Even basic details such as a home address, phone number, or email can be combined with other leaks to build a profile that puts your household at risk.

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.
