Cooper Health System Data Breach Affects 57,412 People: SSNs Exposed

The Cooper Health System, also known as Cooper University Health Care, discovered that it had experienced a data breach affecting the personal information of tens of thousands of individuals. The breach was first identified on March 26, 2025, after an investigation into suspicious network activity that began in May 2024. While the unusual activity did not disrupt access to Cooper’s systems, it prompted immediate action to secure their environment and launch a comprehensive investigation with the help of independent cybersecurity experts.

The investigation revealed that an unauthorized actor may have acquired certain data stored in Cooper’s systems. After a thorough review of the affected files, Cooper determined that the breach exposed sensitive information, including names and Social Security numbers. According to the official disclosure to the Maine Attorney General’s office, a total of 57,412 people in the United States were impacted by this incident, with one individual in Maine receiving direct notification.
