Krebs post at Krebsonsecurity.com has plenty of details on the LizardSquad, from his article:
The Lizard Squad, a band of young hooligans that recently became Internet famous for launching crippling distributed denial-of-service (DDoS) attacks against the largest online gaming networks, is now advertising own Lizard-branded DDoS-for-hire service…Last, but certainly not least, it appears that Vinnie Omari — the young man I identified earlier this week as being a self-proclaimed member of of the Lizard kids — has apparently just been arrested by the police in the United Kingdom (see screen shot below). Sources tell KrebsOnSecurity that Vinnie is one of many individuals associated with this sad little club who are being rounded up and questioned.
I am always interested in how these types of hacks get carried out. You can read the full article from Krebs here. He has plenty of information on the hack.
It looks like the authorities are catching up with the novice hackers.
