French Agency Data Breach Exposed as Hacker Sells Data

France Titres, also known as Agence nationale des titres securises, has disclosed a data breach affecting its online portal, following claims by a threat actor that large volumes of citizen data were stolen. The agency, which operates under the French Ministry of the Interior and manages official documents such as passports, national ID cards, and driver’s licenses, said it detected the security incident on April , 2026. An investigation is ongoing, but initial findings indicate that personal data linked to individual and professional accounts on the ants.gouv.fr platform may have been exposed.

According to France Titres, the potentially compromised information includes login IDs, full names, email addresses, dates of birth, and unique account identifiers. In some cases, additional details such as postal addresses, places of birth, and phone numbers may also have been affected. The agency has begun notifying individuals identified as impacted.

Officials emphasized that the exposed data does not provide direct access to user accounts or internal systems. However, they warned that the information could be used in phishing and social engineering campaigns. Users have been advised to remain vigilant and cautious of suspicious emails, messages, or calls that appear to originate from the agency.
