In a little-noticed event this past January, a 16-year old computer hacker styling himself "Mafia Boy" pleaded guilty to 56 charges related to attacks last year on some of the Internet's largest e-commerce sites, such as Amazon.com, Yahoo! and eBay. The FBI estimates his acts of cyber vandalism caused more than $1.7 billion in damage by slowing or denying access to the Web sites for over six hours. Because of his status as a juvenile, Mafia Boy faces a penalty of two years in detention and a $650 fine. He boasted that he will commit this kind of cyber vandalism again.
