Teenage hackers Jake Davis (a.k.a. Topiary) and Ryan Cleary have both pleaded guilty to charges connected to attacks on the Web sites of the CIA, Sony, PBS, the UK's Serious Organized Crime Agency (SOCA) and many others.

"Davis, who under his 'Topiary' handle became the LulzSec group's [principal] spokesperson from his base in the Shetland Islands, admitted to two of the four charges against him, including his involvement in the attack on SOCA's website," writes Sophos' Graham Cluley. "Cleary admitted to six of eight charges against him, including attacking CIA and US Air Force computers based at the Pentagon."

"However, Cleary and Davis denied they had posted ‘unlawfully obtained confidential computer data’ to various public websites, including The Pirate Bay and Pastebin.com," writes TNW's Matt Brian.

"Cleary and Davis were both members of Lulz Security, or 'LulzSec,' which ran a 50-day hacking campaign in 2011," writes Ars Technica's Peter Bright. "The group, broadly affiliated with Anonymous, hacked some servers, took others offline with distributed denial-of-service attacks, and published large quantities of personal information including usernames, passwords, and e-mails. Ryan Cleary was arrested for his participation in June 2011. Shortly after, Jake Davis was also arrested."

"Alleged co-hackers Ryan Ackroyd, 25, and a 17-year-old A-level student, from south London, deny their involvement in the DDoS attacks and will stand trial on April 8, 2013," writes Mail Online's Damien Gayle.

"All four defendants denied two counts of encouraging or assisting others to commit computer offenses and fraud," writes TG Daily's Trent Nouveau.
