Reports say Geeks.com sent out a letter at the weekend to its customers, admitting that customer information, including names, addresses, telephone numbers, e-mail addresses, credit card numbers, expiration dates, and card verification numbers, may have fallen into the wrong hands.
The website displays a banner from McAfee's ScanAlert service certifying that it is a hacker-safe site.
Calum Macleod, European director at security firm Cyber-Ark, said, "Quite apart from the fact that a supposedly secure website - and one that has been certified as such - has been hacked, it highlights the need for all commercial organisations to encrypt their customer data, if they are not to lose face or even face lawsuits from disgruntled customers."
