Massive cyberattack on French healthcare software exposes personal data of up to 15 million patients
A cyberattack on Cegedim Santé's medical software at the end of 2025 has exposed personal data of up to 15 million French patients.
Attackers breached Cegedim Santé's MonLogicielMedical (MLM) software, which is used by thousands of doctors across France, and stole approximately 15.8 million medical records, including sensitive information such as medical histories and data for high‑profile individuals. French authorities and the health ministry have responded with investigations and security measures to contain the breach and protect affected patients.
