15,000 employees affected by claimed data leak at ANCT

On 4 March 2026, the Agence Nationale de la Cohésion des Territoires (ANCT) — the French public agency tasked with supporting territorial development, rural areas and priority neighbourhoods — was named in a data-leak claim circulating on a hacking forum. A threat actor advertised a database said to be associated with the agency and offered it for sale, publishing a sample as proof of possession.

According to the claim, the dataset affects roughly 15,000 people — employees and administrative contacts linked to ANCT — and contains professional and contact information rather than highly sensitive identity records.

Reported exposed-data categories include:

• Names of employees and administrative contacts
• Professional contact details (email addresses, phone numbers)
• Affiliation with ANCT or related administrative entities

The breach is based on an unverified forum post; the scale and authenticity of the data had not been independently confirmed or publicly acknowledged by the agency at the time of reporting, so the status remains unknown. This incident is distinct from the much larger ANTS (Agence Nationale des Titres Sécurisés) breach disclosed in April 2026.
