Bouygues Telecom, France's third largest mobile phone, has identified cyberattacks and data breaches affecting millions of customers.
In a statement posted to its website, the telecom giant said the hack has allowed intruders to access personal information from 6.4 million customer accounts. Bouygues said it detected a cyberattack on August 4, but did not give a time frame when the violation was improved.
On another page dedicated to CyberAttack victims, Bouygues said the stolen data includes customer contact information and contract data, citizen status (or company data if the subscriber is an expert), Ibans, or international bank account numbers.
Bouygues said it has around 26.9 million mobile customers.
The cyberattack has been reported to CNIL, the French Data Protection Agency.
At the time of publication, Bouygues' webpage on cyberattacks contained a “noindex” tag hidden in the source code. This will instruct the search engine to ignore the page, making it difficult for people searching the web to find the page.
A Bouygues spokesman did not immediately respond to a request for comment asking for details about the cyberattack. He also explained why the page was hidden from search engines.
The news of the violation comes shortly after a cyberattack on French telecommunications giant Orange, the country's largest telephone carrier and one of the world's largest telecommunications companies. On July 29, Orange told customers to expect confusion as they moved to “separate potentially affected services.” Orange serves more than 290 million customers worldwide.
