Free Mobile suffered a October 2024 data breach that exposed information on nearly 23 million mobile and fixed subscribers. Attackers targeted the company's management tool and tried to sell the stolen customer information on a hacker forum, with the exposed records reportedly including IBANs for some people. The exposure raised fraud and identity-theft risk and later contributed to a CNIL enforcement action.
