MotorsportMarkt.de Listed by Everest Ransomware Group

On October 27, 2025, the German motorsport marketplace MotorsportMarkt.de appeared on the leak site of the Everest ransomware group after attackers exfiltrated internal files during a ransomware incident.

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, which runs an online portal for buying and selling motorsport vehicles, parts, equipment, accessories, jobs, properties, and services across cars, motorcycles, karts, and offroad disciplines, had internal files taken. The Everest ransomware group listed the victim on its leak site that same day. The exact number of people whose information may have been exposed remains unknown, and the specific types of data inside the stolen files have not been publicly detailed beyond the broad description of internal company documents. No ransom demand deadline has been disclosed in available reporting.

Why This Matters for You and Your Family

When a marketplace like MotorsportMarkt.de is hit, anyone who created an account, listed a vehicle, applied for a job, or shared contact details could have personal information now in attackers’ hands. That often includes names, email addresses, phone numbers, physical addresses tied to vehicle sales or property listings, and sometimes payment details. For ordinary families who enjoy track days, karting with children, or restoring classic motorcycles, this claimed breach can quietly feed into larger identity problems. Criminals do not limit themselves to one dataset; they combine it with others to build profiles that lead to fraud, phishing, or harassment.

Credential leaks like this one frequently cascade into account takeovers elsewhere, especially when the same email and password are reused on gaming platforms, email services, or banking apps. Children’s accounts are not immune. A teen’s username linked to a family address from a parent’s motorsport listing can become the starting point for doxxing or gaming takeovers.

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.
