Lulzsec, an outfit claiming responsibility for several high-profile attacks in the gaming industry in 2011. Lulzsec is perhaps best known for its attack against Sony as retaliation for legal actions against George Hotz, the guy who rooted the PS3.
Cleary, who is 19, and Davis, the younger of the two at 18, both admitted membership in Lulzsec today at Southwark Crown Court, pleading guilty to "conspiracy to do an unauthorised act or acts with intent to impair, or with recklessness as to impairing, the operation of a computer or computers," Eurogamer reports.
The two both denied making available "unlawfully obtained confidential computer data" on the internet. Two other individuals, 25-year-old Ryan Ackroyd and an unnamed 17-year-old, both denied charges they were involved in Lulzsec hacking.
