Two men suspected of hacking Sony, Nintendo and several other video game companies have pleaded guilty to charges brought against them.

At Southwark Crown Court, U.K., 19-year-old Ryan Cleary and 18-year-old Jake Davis admitted to being members of Lulzsec, a hacking group that was responsible for several distributed denial of service (DDoS) attacks on video game companies last year.

Both men pleaded guilty to two counts of conspiracy to do an unauthorized act or acts with intent to impair, or with recklessness as to impairing, the operation of a computer or computers. However, they deny posting ”unlawfully obtained confidential computer data” on the Internet.

Two other alleged hackers, 25-year-old Ryan Ackroyd and a 17-year-old whose identity has not been made public, pleaded not guilty to all charges. All except Cleary have been released on bail, with a trial date set for April 2013.

Lulzsec was responsible for attacks on the websites of Sony, Nintendo, Bethesda, Minecraft, League of Legends and Eve Online.
