Cyberattack on France’s ANTS portal may have exposed identity document user data
France’s Interior Ministry disclosed a cyberattack on the National Agency for Secure Documents (ANTS) portal, ants.gouv.fr, the government platform used to manage passport, national ID card, residence permit, and driver’s license applications. Detected on April 15, the incident may have exposed personal data tied to individual and professional accounts, including login identifiers, names, email addresses, dates of birth, and account IDs, with some records also potentially containing postal addresses, places of birth, and phone numbers. Officials said uploaded administrative documents were not compromised and that the exposed data cannot be used to directly access ANTS accounts.
French authorities reported the breach to CNIL, notified prosecutors, and alerted the national cybersecurity agency as investigators work to determine the scope, origin, and impact of the intrusion. The number of affected users has not been disclosed, but impacted individuals are being notified and urged to watch for suspicious messages. Separately, an unverified threat actor has claimed to be selling a dataset allegedly stolen from ANTS containing roughly 18–19 million records, heightening concerns over identity theft and fraud if the claim is confirmed.
