Carphone Warehouse suffers a "sophisticated cyber-attack," with hackers possibly getting access to the personal details and bank details of 2.4 million customers, as well as 90000 customer credit cards.
The breach affects the Carphone Warehouse division operating OneStopPhoneShop.com, e2save.com and Mobiles.co.uk. Also affected are a number of services provided to iD Mobile, TalkTalk Mobile, Talk Mobile, and to certain Carphone Warehouse customers.
“We take the security of customer data extremely seriously, and we are very sorry that people have been affected by this attack on our systems" Dixons Carphone CEO Sebastian James says. "We are, of course, informing anyone that may have been affected, and have put in place additional security measures.”
The retailer is contacting customers on the breach, but security experts urge the change passwords and ensuring these are not used for other services such as email addresses and online banking.
