Maileva, a subsidiary of the La Poste group, has been the victim of a cyberattack that occurred in mid-September. The theft involves the contact details of 22 million people, La Poste announced on Saturday, November 14.
According to a statement by La Poste to AFP, the attack exposes the first name, last name and postal address of 22 million recipients of Maileva's corporate clients.
The Maileva platform is used by private companies, public institutions, health organizations and government administrations, cyberattaque.org specifies.
These clients use it to send mail, invoices, payment reminders and administrative documents that are sometimes confidential.
Maileva notifies the National Commission on Informatics and Liberties (CNIL) and files a complaint, La Poste says.
The information made public concerns the identity and postal address of the recipients involved. In this announcement, La Poste does not disclose any other categories of data.
