Millions of Carphone Warehouse customers may have had their personal details accessed after the company was hit by a cyber attack.
The mobile phone retailer said that up to 2.4 million customers could be affected by the attack, giving hackers access to names, addresses, dates of birth and bank details.
A statement released by the firm also warned that the encrypted credit card information of up to 90,000 customers may have been accessed.
Carphone Warehouse said the security breach, which happened on Wednesday, affected a division of the company that operates websites OneStopPhoneShop.com, e2save.com and Mobiles.co.uk and provides services to iD Mobile, TalkTalk Mobile, Talk Mobile and some Carphone Warehouse customers.
Sebastian James, group chief executive of Dixons Carphone, said: “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.
“We are, of course, informing anyone that may have been affected, and have put in place additional security measures.”
Angry customers have taken to Twitter to vent their frustration with the security breach, some saying more should have been done to prevent the attack.
