French Media Report Cyberattack on Bouygues Telecom, Millions of Customers Affected

According to French media reports, Bouygues Telecom, one of the country’s largest telecommunications providers, has fallen victim to a major cyberattack that compromised the personal information of millions of users. The company, which serves more than 26 million mobile subscribers, confirmed that the incident exposed sensitive data linked to customer accounts.

The breach, detected in early August, allowed attackers to gain access to contact information, contract details, and even International Bank Account Numbers (IBAN) belonging to both private individuals and businesses. While Bouygues stressed that no passwords or payment card information had been exposed, the scope of the incident remains significant.

Company officials disclosed that approximately 6.4 million customers were affected. Those impacted are being contacted via email and text message, with urgent warnings to remain vigilant against fraudulent calls or phishing attempts seeking to exploit the stolen data.

So far, no ransomware group has claimed responsibility for the breach, and the motives behind the attack remain unclear. The incident comes just days after another French telecom giant, Orange, experienced a separate cyberattack in late July. Industry experts highlight that telecom operators remain high-value targets for both state-sponsored hackers and financially motivated cybercriminals, with recent attacks underscoring the urgent need for stronger defenses.
