France Titres, the government agency in France for issuing and managince administrative documents has disclosed a data breach after a threat actor claimed the attack and stealing citizen data. Also known as Agence nationale des titres sécurisés (ANTS), the administrative body operates under the French Ministry of the Interior, serving as the managing authority for official identity and registration documents in France. This includes driver’s licenses, national ID cards, passports, and immigration documents. According to an announcement the agency published yesterday, the attack occurred last week, and while the investigation is still ongoing, several data types for an undisclosed number of individuals may have been exposed. “On Wednesday, April 15, 2026, the National Agency for Secure Documents (ANTS) detected a security incident that may involve the disclosure of data from individual and professional accounts on the ants.gouv.fr portal,” reads ANTS’s announcement. ANTS stated that it is currently in the process of notifying those identified as impacted. The agency noted that the exposed information does not allow unauthorized access to its electronic portals. However, the same data can be used in phishing and social engineering attacks. “No action is required from users. However, they are advised to remain highly vigilant regarding any suspicious or unusual messages they may receive (SMS, phone calls, emails, etc.) that appear to come from ANTS,” the agency warned. ANTS has notified the data protection authority (CNIL), the Paris Public Prosecutor, and has also involved the national cybersecurity agency (ANSSI) in the response effort. The agency warned that the sale or dissemination of the data is illegal.
