France Titres, the French agency formerly known as ANTS and responsible for identity and registration documents, confirmed a breach of its ants.gouv.fr portal after threat actor breach3d advertised a trove of stolen records for sale on cybercrime forums. The agency said the compromised data may include login IDs, full names, email addresses, dates and places of birth, account identifiers, and in some cases postal addresses and phone numbers from both individual and professional accounts. Other reporting on the sale listings said the dataset could contain 18 million to 19 million records, including fields indicating government-verified identities, raising the risk of phishing, social engineering, and identity fraud if the claims are fully accurate.
French authorities said unusual activity was identified in mid-April and launched parallel technical and judicial investigations involving ANSSI, CNIL, the Paris Public Prosecutor, and anti-cybercrime investigators. Prosecutors later announced the arrest of a 15-year-old suspect in connection with the case after records linked to the agency were allegedly offered for sale online, and said the inquiry covers unauthorized access, persistence, and extraction of personal data from a state-operated system. France Titres has notified affected individuals and said the stolen information does not provide direct access to user accounts or the portal itself, while warning citizens to remain alert for follow-on scams and impersonation attempts.
