An anonymous reader writes Security researcher Mikko Hyppönen from F-Secure told the newspaper Helsingin Sanomat and Finland's MTV news that rumours have been circulating for several months about the Lizard Squad group of hackers who say they disrupted the two computer games console networks on Christmas Day. He confirmed that at least one of them is a Finn. One of the hackers, in a Skype interview from Finland by Britain's Sky News, said that the attack was carried out for amusement and to expose security flaws in the networks. Hyppönen told Helsingin Sanomat and MTV that his company has been aware of the hacker group for several months. 'According to our information, the group has members in the United States, Canada, England and at least one member in Finland,' he told MTV. The nationalities of other members that participated in the Christmas attack have not been confirmed. Hyppönen noted that these kinds of groups come and go, and that their members are usually young.
