Southcoast Health Data Breach Exposes Social Security Numbers

Southcoast Health System Inc, a not-for-profit, community-based health system in southeastern Massachusetts, disclosed a data breach that exposed consumers' personal information.

On Feb. 16, 2026, a Southcoast Health user account was compromised, resulting in a breach of security and unauthorized access to personal information. The compromised account allowed an unauthorized party to access the personal data of affected individuals during the period of the compromise.

The incident involved a single user account rather than a broader system intrusion, and the company described the duration of the compromise as brief.

The personal information exposed in the breach included names and Social Security numbers.

The breach was disclosed to the Massachusetts Office of Consumer Affairs and Business Regulation on May 5, 2026.
