In late 2025, the Everest ransomware group claimed to have breached Chrysler systems, an American automaker, and exfiltrated 1088 GB (over 1 TB) of data. This incident was disclosed on December 26, 2025, by Hackread.com, referencing a post by the Everest group on their dark web leak site on December 25, 2025. The stolen data reportedly spans from 2021 through 2025 and includes more than 105 GB of Salesforce-related information, described as a full database linked to Chrysler operations.
The compromised data types include full names, addresses, phone numbers, dates of birth, and Social Security numbers (SSNs). The Everest group claims the data contains extensive personal and operational records tied to customers, dealers, and internal agents. While an exact number of affected individuals has not been confirmed, class-action lawsuits indicate "tens of thousands" of customers were impacted. No medical records or financial account details such as bank numbers or credit card information have been mentioned as compromised.
Stellantis, Chrysler's parent company, has not publicly confirmed the breach or issued notifications as of early 2026 reports. Details are primarily based on the ransomware group's claims and subsequent class-action lawsuits. More information may emerge as investigations unfold and official statements, if any, are released.
