On August 4, 2025, Bouygues Telecom, one of France’s leading telecommunications providers, experienced a significant cyberattack that has compromised the personal data of approximately 6.4 million customers. The breach involved access to sensitive information such as contact details, contractual agreements, civil status, and the banking information (IBANs) for professional accounts. Fortunately, the company confirmed that more sensitive data, including credit card numbers and account passwords, remained secure and were not compromised during the attack.
In the wake of the cyber incident, Bouygues Telecom is notifying affected customers via email and SMS messages. The company has taken proactive steps to inform users about potential fraudulent activities, emphasizing that scammers may use the leaked data to impersonate Bouygues Telecom and other entities like banks or insurance companies. Customers are therefore advised to exercise caution and are warned against sharing personal information, such as identifiers or passwords, especially in response to unsolicited communications.
For customer support, Bouygues Telecom has established a special helpline at 0801 239 901 and created a dedicated webpage for affected individuals. Customers are urged to regularly monitor their accounts and report any suspicious transactions to their banks. In addition, Bouygues Telecom has recommended that users consult the government’s official platform for advice on digital fraud prevention and reporting.
