Leak at Puteaux Medical Imaging Centre

On 28 January 2026, the Centre d'Imagerie Médicale de Puteaux — a radiology and medical imaging centre in Puteaux (Hauts-de-Seine), serving patients across the Puteaux–Neuilly–Courbevoie area — was the subject of a confirmed data breach in which patient personal information was exposed.

The exposed records concerned patients of the centre and included a combination of identity and contact details alongside appointment-booking information. The categories of data involved were:

• Surname and first name
• Date of birth
• Phone number
• Email address
• Postal address
• Number of appointments

The precise origin of the leak and the number of patients affected have not been publicly disclosed. As with many French healthcare facilities, patient identity and contact data of this kind is highly sensitive and can be exploited for targeted phishing, identity fraud and social-engineering attacks against the individuals concerned.

The breach was catalogued as confirmed by the French leak-tracking project bonjourlafuite.eu.org. No public statement from the centre, attacker claim, or regulator (CNIL) filing detailing the scale or remediation has been identified, and the overall status of the incident remains unclear.
