Dixons Carphone has launched an investigation after admitting to a massive data breach involving 5.9 million payment cards and 1.2 million personal data records.

According to a statement released by the company, Dixons Carphone said that had been “unauthorized access to certain data” held by the company.

The company said that in its ongoing investigation, it found that there was an attempt to compromise 5.9 million cards in one of the processing systems of Currys PC World and Dixons Travel stores. It added that 5.8 million of these cards have chip and pin protection.

“The data accessed in respect of these cards contains neither pin codes, card verification values (CVV) nor any authentication data enabling cardholder identification or a purchase to be made,” said the company in a statement.

It added that around 105,000 non-EU issued payment cards which do not have chip and pin protection have been compromised. Dixons Carphone said that as a precaution, it has notified the relevant card companies via its payment provider about all these cards so that they could take the appropriate measures to protect customers. It said that it had no evidence of any fraud on these cards as a result of this incident.
