Ministry of the Interior, Ministry of Economy and Auchan: In a tsunami of data leaks, French society remains vulnerable and authorities powerless

France Faces Unprecedented Surge in Data Breaches as Cybersecurity Gaps Persist

France is grappling with a historic wave of data breaches, with cyberattacks and accidental leaks exposing millions of individuals across both public and private sectors. According to a May 19 report from the National Commission for Information Technology and Civil Liberties (CNIL), 6,167 data breaches were reported in 2024 a 10% increase from the previous year with nearly half attributed to hacking.

The scale of the crisis is staggering: over the past two years, roughly 80 breaches have each impacted at least one million people. Targets have included critical government agencies, such as the Interior and Economy Ministries, the National Agency for Secured Documents, and the national employment agency, as well as major corporations like telecom provider Free and supermarket chain Auchan. Private health insurers and labor unions have also been hit.

The surge has overwhelmed authorities, with Johanna Brousse, deputy prosecutor and head of the Paris prosecutor’s cybercrime unit, reporting an "explosion" in investigations sometimes as many as 10 per week. While some breaches stem from single incidents affecting multiple entities (e.g., a compromised service provider), roughly half of CNIL’s notifications involve deliberate cyberattacks, with the remainder resulting from accidental exposures.

As 2025 shapes up to surpass previous records, the trend underscores persistent vulnerabilities in France’s cybersecurity defenses across industries.
