French telecommunications company Bouygues Telecom announced it was the target of a cyberattack that compromised the personal data of approximately 6.4 million customers. The breach, detected earlier in the week, involved the theft of sensitive information including customers' IBAN bank details and civil status data. This exposure raises concerns about potential fraud and unauthorized subscriptions affecting the victims. Bouygues Telecom has alerted affected customers and advised them to take precautions to prevent misuse of their financial information. The incident represents one of the largest data breaches in the French telecom sector to date.
