Important data information issue 8th August 2015

1. What happened?

On 5 August we discovered that the IT systems of a division of Carphone Warehouse in the UK had been breached by a sophisticated cyber-attack. This division operates the website’s OneStopPhoneShop.com, e2save.com and Mobiles.co.uk, and provides a number of services to iD Mobile, TalkTalk Mobile, Talk Mobile, and to certain customers of Carphone Warehouse.

We took immediate action to secure these systems and launched an investigation with a leading cyber security firm to determine exactly what data was affected. We have also put in place additional security measures to prevent further attacks.

Our investigation has indicated that personal data which may include names, addresses, dates-of-birth, and bank details of up to 2.4 million customers, may have been accessed. Encrypted credit card data of up to 90,000 customers may also have been accessed.
