A 15-year-old boy working under the nom-de-plume Mafiaboy has been charged with two counts of mischief for disabling the CNN site for four hours. The attack was one of several on major international Web sites in recent months that highlighted the security risks of the high-tech age. The young hacker - arrested Saturday in a joint investigation with the FBI ? had been boasting in Internet chat rooms frequented by hackers that he was responsible for a number of the attacks, said Inspector Yves Roussel of the Royal Canadian Mounted Police. But despite his on-line boasts, he so far has only been charged in the attack on CNN. The attack affected hundreds of other sites hosted by the CNN site, police said. Chris Painter, deputy chief of the U.S. Justice Department’s computer crime section, said the FBI and RCMP found Mafiaboy using a combination of traditional and cyber investigative techniques. An RCMP investigator said the boy was tracked through traces he left of his computer activity. ?Mafiaboy wasn’t that good,? staff Sgt. Jean-Pierre Roy said. ?He wasn’t what we would call a genius.? In fact, many online are claiming that Mafiaboy is just an example of a ?script kiddy? who got unlucky. Script kiddes use scripts written by other hackers without necessarily understanding the technical implications of the hacks they use.  Police used a search warrant to enter the boy’s house on Saturday and seized computers and software equipment. The boy appeared Monday in Youth Court. He was released under bail conditions that included a ban on connecting to the Internet or going to libraries, universities, stores and other places with public access to computers or computer equipment.As a youth offender, Mafiaboy could be sentenced to up to two years in prison if convicted.
