France, attack on the Post Office: hackers steal data of 22 million customers

Maileva, a subsidiary of the La Poste group specializing in professional mail delivery, was the victim of a serious cyberattack in mid-September, which led to the theft of the personal data of 22 million people. La Poste made this known to the AFP agency yesterday. Maileva "has notified the incident to the Cnil," the data protection authority, and has filed a complaint: "A judicial investigation is underway," La Poste added, confirming what was reported by the specialized sites FrenchBreaches and cyberattaque.org, according to which this is "one of the largest data breaches in France." Maileva – specializing in professional mail for small and medium-sized businesses – has over 70,000 users and in 2024 handled the delivery of 180 million documents. The attack "resulted in the exposure of the personal data (first name, last name, postal address) of 22 million people, recipients of the mail sent on behalf of Maileva's client companies," the La Poste group specified in a statement. Last year, just days before Christmas, La Poste had already been hit by a cyberattack, claimed by pro-Russian hackers.
