The Carphone Warehouse and Currys PC World owner has been investigating the hack since it was discovered in June. It said personal information, names, addresses and email addresses may have been accessed last year. However, no bank details were taken and it had found no evidence that fraud had resulted from the breach. The hackers also got access to records of 5.9 million payments cards, but nearly all of those were protected by the chip and pin system. Dixons said it was "very sorry for any distress" caused and it would be apologising to customers, although it did not say how or over what timescale it would be contacting them.
