1,150 people affected by a data leak at Notre-Dame des Dunes

On 4 February 2026, the Collège-Lycée Notre-Dame des Dunes — a private Catholic secondary school (collège and lycée) in Dunkirk, in the Nord department of France — was reported to have suffered a confirmed data leak affecting its school community.

According to the French breach tracker fuitesinfos.fr, the incident exposed personal data belonging to roughly 1,150 people, primarily the school's pupils together with staff members and external contributors associated with the establishment. As a secondary school, the institution holds records on minors, which raises the sensitivity of the exposure.

Likely categories of affected individuals and data include:

• Pupils enrolled at the collège and lycée
• Teaching staff and other school personnel
• External contributors and partners working with the school
• Associated identity and contact details held in the school's systems

The precise attack vector, the full set of data fields exposed, and the school's response have not been independently confirmed in public reporting beyond the tracker entry, and the status of the incident remains unknown. This February 2026 incident should not be confused with the separate, nationwide breach of France's EduConnect / Éducation nationale platforms disclosed in April 2026.
