French public office hit with €5 million CNIL fine after massive data leak

The data protection authority of France has imposed a €5 million penalty on France Travail after a massive data breach exposed sensitive personal information collected over two decades.

A leak which included social security numbers, email addresses, phone numbers and home addresses of an estimated 36.8 million people who had used the public employment service. CNIL said adequate security measures would have made access far more difficult for the attackers.

The investigation found that cybercriminals exploited employees through social engineering instead of breaking in through technical vulnerabilities.

CNIL highlighted the failure to secure such data breach requirements under the General Data Protection Regulation. The watchdog also noted that the size of the fine reflects the fact that France Travail operates with public funding.

France Travail has taken corrective steps since the breach, yet CNIL has ordered additional security improvements.

The authority set a deadline for these measures and warned that non-compliance would trigger a daily €5,000 penalty until France Travail meets GDPR obligations. A case that underlines growing pressure on public institutions to reinforce cybersecurity amid rising threats.
