Monro, Inc.

Monro, Inc.

The Maine Office of the Attorney General disclosed a data breach affecting Monro, Inc. on March 25, 2025, which was initially detected on November 29, 2024. The incident involved unauthorized access to an employee’s email account, exposing sensitive personal information of 112,458 individuals, including names and Social Security numbers (SSNs). The breach stemmed from a compromised employee mailbox, likely due to phishing or credential theft, enabling attackers to exfiltrate personally identifiable information (PII). While the full scope of misuse remains unclear, the exposure of SSNs heightens risks of identity theft, financial fraud, and long-term reputational damage for the company. Monro, Inc., a provider of automotive undercar services, now faces regulatory scrutiny, potential lawsuits, and the operational burden of notifying affected individuals, offering credit monitoring, and reinforcing cybersecurity protocols to prevent future incidents.
