Kelly Fiveash reports:
Carphone Warehouse has taken three days to go public about a serious data breach affecting nearly 2.5 million customers – with the confession that up to 90,000 subscribers may have had their credit card info ransacked.
The company said in a statement on Saturday afternoon that it had first discovered its systems had been violated by a “sophisticated cyber-attack” on 5 August.
Encrypted credit card data of up to 90,000 customers may have been lifted by malefactors, it added.
Carphone Warehouse said its websites OneStopPhoneShop.com, e2save.com and Mobiles.co.uk had been affected by the attack. Those sites provide services for customers at iD Mobile, TalkTalk Mobile, Talk Mobile and an undisclosed number of Carphone Warehouse customers.
