Healthcare Data Breach Disclosures and Legal Fallout
French healthcare software provider Cegedim Santé confirmed a major breach affecting its MonLogicielMedical (MLM) product after unusual activity was detected in late 2025. The incident exposed administrative data tied to roughly 1,500 doctors (out of ~3,800 users) and patient data at large scale—reported as 15.8 million records, including 165,000 files that may contain doctors’ notes; while structured medical records were reported as intact, some administrative comments may include sensitive clinical notes and highly sensitive details (e.g., HIV/AIDS status or sexual orientation). Cegedim Santé reported notifying French authorities including CNIL and filing a complaint.
In the US, Cornerstone Specialty Hospitals agreed to a $2.35M class-action settlement tied to a December 2023 network intrusion that ultimately affected 484,957 individuals, with potentially exposed data spanning identifiers (including SSNs and government IDs), financial data, credentials, and health/insurance information; the suit also alleged delayed notification (letters mailed around July 2024). Separately, PIH Health began notifying patients about a December 2024 ransomware attack that disrupted multiple hospitals and services; investigators concluded the attacker had network access from Nov 14–Dec 23, 2024, and after a prolonged review PIH Health confirmed in Dec 2025 that patient information was present in files on compromised systems and may have been accessed or acquired, with notification letters prepared by Feb 25, 2026 amid claims of large-scale data theft and some data leakage online.
