News Burst: Biggest hacking fraud ever

Every e-commerce site's nightmare as hacker gets nasty with credit card details

A malevolent computer hacker claims to have pulled off the greatest information technology heist in history after temporarily posting credit-card numbers stolen from a large US e-commerce firm.

American online CD-retailer cdUniverse, admitted that "a portion of its customer data" had been stolen and that an attempt had been made to blackmail the firm over the return of the information.

eUniverse -- parent of cdUniverse -- admitted it was contacted by a malicious hacker last week who claimed to have stolen thousands of credit card numbers. The hacker demanded thousands of dollars not to go public according to eUniverse. After calling the blackmailer's bluff, eUniverse discovered hundreds of card numbers had been posted to an anonymous Web site.
