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 dealership, which specializes in customized mobility and service packages with access to new and used Mercedes-Benz vehicles nationwide, was hit by a ransomware attack. The Akira group posted proof of the breach on its leak site, stating it is prepared to publish the full cache of stolen files. Available reporting describes the exposed material as essential corporate documents rather than a full customer database, yet the presence of names, emails, phone numbers, payment records, and contracts means sensitive personal and financial information is now at risk of further distribution.

April 18, 2025 marks the public listing date. The exact number of individuals affected remains unknown, but any customer or employee whose details appear in the invoices, contracts, or contact lists could face identity-related consequences.

Why This Matters for You and Your Family

When a local car dealership that handles service records, financing, and personal contracts suffers a breach, your information can quickly move beyond the original company. If you or any member of your family has ever bought, leased, or serviced a Mercedes-Benz through Heinz Hammer Vertragswerkstatt, your email, phone number, payment history, or contract details may now sit in a ransomware leak repository. That data can be sold, traded, or used to launch further 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.
