Cont.Important message from Dixons Carphone
On June 13, we began to contact a number of our customers as a precaution after we found that some of our security systems had been accessed in the past using sophisticated malware.
We promptly launched an investigation. Since then we have been putting further security measures in place to safeguard customer information, increased our investment in cyber security and added additional controls. In all of this we have been working intensively with leading cyber security experts.
Our investigation, which is now nearing completion, has identified that approximately 10 million records containing personal data may have been accessed in 2017. This unauthorised access to data may include personal information such as name, address, phone number, date of birth and email address.
There's fair bit more after that, so if a customer of Dixons CPW or PC World definitely read all of it.
