Three LulzSec members plead guilty in London

Three members of the LulzSec hacking group, which gained international notoriety in the spring of 2011 for a series of intrusions against high-profile companies and government agencies, pleaded guilty Tuesday in London, according to reports.

Ryan Ackroyd, 26; Jake Davis, 20; and Mustafa al-Bassam, 18, who was not named until now because of his age, all admitted their involvement in the hacking spree.

Ackroyd, who used the online alias of a 16-year-old girl named "Kayla," pleaded guilty to one count of carrying out an unauthorized act to impair the operation of a computer after he helped infiltrate companies that included Sony, Nintendo, 20th Century Fox and the Arizona Department of Public Safety. Davis and al-Bassam pleaded guilty to launching distributed denial-of-service (DDoS) against the CIA and Serious Organised Crime Agency in the U.K.

The trio is scheduled to be sentenced May 14.

Previously, Ryan Cleary, had pleaded guilty to launching DDoS attacks against those organizations.
