Talk Talk is one of the biggest players in the UKs Broadband and phone communication companies. It has over four million customers and now there has been a huge data breach on customer’s information-including banking information.

TalkTalk Telecom Group plc was founded in 2003 as a subsidiary of Carphone Warehouse and was demerged as a standalone company in March 2010. Since August 2012, TalkTalk has become the UK’s second quadruple play service after Virgin Media, offering TV, broadband, phone, and mobile services.

The phone and broadband provider, which has over four million UK customers, said banking details and personal information could have been accessed.

TalkTalk said potentially all customers could be affected but it was too early to know what data had been stolen.

The Metropolitan Police said no-one had been arrested over Wednesday’s attack but enquiries were ongoing.

TalkTalk said in a statement that a criminal investigation had been launched on Thursday.

It said there was a chance that some of the following customer data, not all of which was encrypted, had been accessed:
