Data of tens of millions of French people leaked online - Le Figaro.
France experienced one of the largest personal data leaks in recent years. About 22 million people became victims of a cyber attack on the Mahmia platform, owned by Dukapost, a subsidiary of the La Poste postal group. The Post Office itself reported this on November 14. The attackers gained access to the users' first and last names and email addresses.
The attack took place in mid-September 2026, but the true extent of the leak was not known until almost two months later. Mahmia is used by companies to send various documents: invoices, payslips, registered letters and legal notices. Thus, among the victims were recipients of correspondence from factories, medical institutions and social organizations. According to the company, people's bank details were not compromised as a result of this attack.
After discovering the incident, Mailba notified the French National Commission for Informatics and Liberties (CNIL), submitted a report to law enforcement authorities, and a legal investigation was opened. The company also said it has notified organizations that may have had their customers affected by the leak. Experts warn that stolen names and addresses can be used for targeted mailings and phishing attacks.
