British smartphone retailer Carphone Warehouse has confirmed that its systems were hacked last week, leaving 2.4 million customers at risk. Using a “sophisticated cyber-attack,” hackers were able to access personal data, including names, addresses, dates of birth, and even bank details.
Carphone Warehouse, while also operates OneStopPhoneShop.com, e2save.com, and Mobiles.co.uk, took all of its websites offline on Saturday after publicly confirming the attack. 480,000 customers subscribed to the retailer’s own iD network are also thought to be affected.
Although credit card data was encrypted, card details of 90,000 customers “may have also been accessed,” Carphone Warehouse has admitted.
“The company has sent a letter to anyone who may be at risk via email, alerting them to the situation and providing information on what they can do next,” reports The Telegraph. “They have been told to notify their bank, and check for any suspicious or unexpected account activity.”
Carphone Warehouse has also advised that customers should be wary when they receive a call from someone claiming to be from one of the websites listed above. Those who do become victims of fraud should contact Action Fraud, the national fraud and internet crime agency.
“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,” said Sebastian James, CEO of Dixons Carphone, the company that owns Carphone Warehouse, PC World, and Currys.
“We are, of course, informing anyone that may have been affected, and have put in place additional security measures,” he added.
