According to a March 10th eWeek article by Lisa Vaas, a self-proclaimed Romanian hacker posted eBay member information at an eBay forum ("Romanian Hacker Broadcasts eBay Customer Accounts") . The hacker, who calls himself "Born_To_Scam_American_Guys", also posted what amounts to a critique of American and Canadian computer users and their alleged helpful stupidity.
Many of the posts were valid while some were for unvalidated membership requests. eBay is working to notify affected users. Information provided by the hacker included "...Social Security numbers, credit card numbers, credit card verification numbers, bank account and routing numbers, ATM PIN numbers, mothers' maiden names, birth dates, driver's license numbers, as well as home addresses and full contact information."
