On August 21, 2025, the German medical practice fiermann-eller.de appeared on the leak site of the dragonforce ransomware group after its internal files were allegedly 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 practice, which provides general and internal medicine services in Germany, had data taken by the attackers. The exposed material consists of internal files. The number of patients or staff whose records were taken remains unknown. The listing was published on the group’s onion site and mirrored on ransomware tracking platforms such as ransomware.live. No evidence has surfaced that the stolen files have been distributed beyond the leak site at the time of writing.

Why This Matters for You and Your Family

When a doctor’s office is hit, the information taken often includes names, addresses, dates of birth, health details, insurance numbers, and sometimes phone numbers or email addresses of ordinary patients. If your family sees this doctor or shares the same health-insurance network, your records could be among those now sitting on a criminal server. Health data is especially sensitive because it can be used for identity theft, insurance fraud, or targeted scams that sound believable because the caller already knows your medical history. Even if you never visit this specific practice, credential leaks from connected systems can spread quickly to other services your family uses.

The Doxxing and Identity-Chain Implications

Stolen medical files rarely stay isolated. Attackers combine names and addresses with emails or phone numbers found in the same dataset, then search underground forums for matching gaming usernames, social-media handles, or school records. This creates an identity chain that links your real name to your children’s Roblox or Minecraft accounts, their parents’ work emails, and family phone numbers. Once the chain exists, opportunistic criminals can launch doxxing campaigns, SIM-swapping attempts, or extortion demands. Public reporting shows these cascades frequently begin with exactly the kind of internal files now exposed here.

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.
