The devastating Christmas Day attacks against the gaming networks of Sony and Microsoft were a marketing scheme for a commercial cyberattack service, according to the hackers claiming responsibility for the attacks. Known as Lizard Squad, the hacker collective says it shut down the PlayStation Network (PSN) and Xbox Live network on Dec. 25 using a distributed denial-of-service (DDoS) attack, a common technique that overloads servers with data requests. The powerful attacks rendered the networks unusable for days, infuriating gamers around the world and causing yet-untold losses of revenue. Now, members of Lizard Squad say the group is selling the DDoS service they used against Sony and Microsoft to anyone willing to pay. http://yro.slashdot.org/story/14/12/...r-ddos-service
