10m customers affected by Dixons Carphone data breach

Dixons Carphone has said that a 2017 data breach involved 10 million customers, up from its original estimate of 1.2 million.

The electricals and mobile phone retailer first revealed the hack in June. “Our investigation, which is now nearing completion, has identified that approximately 10 million records containing personal data may have been accessed in 2017,” it said in a statement. “While there is now evidence that some of this data may have left our systems, these records do not contain payment card or bank account details and there is no evidence that any fraud has resulted.”

Chief Executive Alex Baldock commented: “Since our data security review uncovered last year's breach, we've been working around the clock to put it right. That's included closing off the unauthorised access, adding new security measures and launching an immediate investigation, which has allowed us to build a fuller understanding of the incident that we're updating on today. As a precaution, we're now also contacting all our customers to apologise and advise on the steps they can take to protect themselves."
