Data breach — Low

The École supérieure d'arts et médias (ésam), based in Caen and Cherbourg-en-Cotentin, suffered unauthorized access to its hosting infrastructure and related applications on August 21, 2026, only detected on September 3 — partly because the school was closed for summer. On September 8, 2026, the school issued a statement saying personal data of users and staff may have been exposed, without specifying the number of people affected, the exact data categories, or whether data was actually exfiltrated. The school notified the French data protection authority (CNIL) and filed a criminal complaint.
