Major Data Breaches Hit French Companies Air France and Bouygues Telecom

In two significant incidents, French companies Air France and Bouygues Telecom have reported data breaches affecting customer information, raising concerns about data security and potential fraud.

On August 6, Air France announced that it had suffered a data breach due to unauthorized access to a system operated by a third-party service provider. Although no sensitive information such as credit card numbers or passport data was compromised, less sensitive data, including names, contact details, and Flying Blue numbers, was accessed. Air France has taken immediate steps to secure the affected system and reported the breach to the French National Commission on Informatics and Liberty (CNIL). The airline cautioned customers to remain vigilant against potential phishing attempts utilizing the exposed information.

In a separate incident, Bouygues Telecom revealed that a cyberattack on August 4, 2025, affected around 6.4 million customer accounts. The breach included personal details such as contact information, contractual data, civil status information, and International Bank Account Numbers (IBANs). Similar to Air France, Bouygues Telecom confirmed that credit card numbers and account passwords were not compromised. The company has begun notifying affected customers via email and SMS and emphasized the need for vigilance against fraudulent activities. Customers are advised to not share sensitive personal information and to report any unusual banking activities.

Both companies are managing responses to mitigate risks from these breaches. Bouygues Telecom has established a dedicated webpage and a helpline (0801 239 901) to assist impacted customers. Air France’s prompt action to secure their system and alert the authorities highlights serious commitments to restoring customer trust.

Meanwhile, customers of both companies are on high alert, with both firms urging them to be cautious of potential scams that may exploit the compromised data. Expert advice continues to underscore the importance of vigilance in this digital age, especially following such significant breaches.
