Summary

In late September 2025, Mavis Tire Supply LLC aka Mavis Discount Tire (one of the largest independent multi-brand tire and auto service retailers in the U.S.) suffered a ransomware attack conducted by the WorldLeaks group.

The incident disrupted portions of the company's IT systems and was first detected on September 23, 2025, with data later confirmed posted to dark web forums on October 7, 2025.

WorldLeaks claims to have accessed and exfiltrated sensitive personal and operational data. The leaked dataset reportedly includes customer identity information, employee contact records, and home addresses linked to service accounts across multiple states.

Mavis operates over 700 service centers in 13 U.S. states, providing tire, brake, and maintenance services.

As of this report, portions of the stolen data are confirmed to be circulating on leak forums and have been indexed by DataBreach.com.
