Talk Talk Help > Potential issue affecting the personal information of mobile customers On Wednesday 5th August, our partners at Carphone Warehouse advised us that our mobile sales site (mobile.talktalk.co.uk), which they host, was subject to a sophisticated and co-ordinated cyber attack, along with a number of other similar websites.
As soon as they realised this, Carphone Warehouse shut down the sites. They’re now working with a leading cyber security firm to make sure our mobile sales website is completely secure.
However, we believe that some of our mobile customers’ data may have been accessed by the criminals. This includes customers’ names, addresses, dates of birth, bank details and other personal and TalkTalk account information.
