Stolen Facebook ID's For Sale

As a followup to my previous post, this is what happens when a hacker has access to Facebook accounts. They make a profit out of them... and people are buying them up.

Researchers at VeriSign's iDefense group recently spotted Kirllos selling Facebook user names and passwords in an underground hacker forum, but what really caught their attention was the volume of credentials he had for sale: 1.5 million accounts.
IDefense doesn't know if Kirllos' accounts are legitimate, and Facebook didn't respond to messages Thursday seeking comment. If they are legitimate, he has the account information of about one in every 300 Facebook users. His asking price varies from US$25 to $45 per 1,000 accounts, depending on the number of contacts each user has.
To date, Kirllos seems to have sold close to 700,000 accounts, according to VeriSign Director of Cyber Intelligence Rick Howard.
