Retailer Dixons Carphone has gone public about a hack attack involving 5.9 million payment cards and 1.2 million personal data records.

In a statement (PDF), Dixons Carphone said that "unauthorised access" of data held by the company had prompted an investigation, the hiring of external security experts and efforts to shore up its security defences. It has informed police, regulators at the Information Commissioner's Office and the Financial Conduct Authority.
