The online attack service launched late last year by the same criminals who knocked Sony and Microsoft’s gaming networks offline over the holidays is powered mostly by thousands of hacked home Internet routers, KrebsOnSecurity.com has discovered. Just days after the attacks on Sony and Microsoft, a group of young hoodlums calling themselves the Lizard Squad took responsibility for the attack and announced the whole thing was merely an elaborate commercial for their new “booter” or “stresser” site — a service designed to help paying customers knock virtually any site or person offline for hours or days at a time. As it turns out, that service draws on Internet bandwidth from hacked home Internet routers around the globe that are protected by little more than factory-default usernames and passwords.
