Lifespan Physician Group of Massachusetts, doing business as Brown Health Medical Group-MA, is notifying over 311,000 individuals that their personal, medical, and financial information was stolen in a data breach. The incident occurred in December 2025 at its Hawthorn location. It involved a historic file server, the healthcare organization says in a sample notification letter filed with the Massachusetts Office of Consumer Affairs and Business Regulation. While the practice’s electronic health record system was not affected, Brown Health Medical Group-MA determined on June 22, 2026, that the attackers accessed files containing personal information. The potentially compromised information, it says, includes names, contact information, dates of birth, Social Security numbers, driver’s license numbers, government ID numbers, medical and disability-related records, financial account information, and credit/debit card numbers.
