Three members of LulzSec pleaded guilty to a computer hacking campaign that targeted many high-profile firms.
As reported by the BBC, Ryan "kayla" Ackroyd, 26, admitted in a London courtroom to working with the hacktivist group, which carried out cyber attacks on high-profile targets like Fox, Sony Pictures, Statfor, and others.
The Anonymous "go-to hacking guy," Ackroyd regularly posed as a 16-year-old girl named Kayla and participated in hacks against security firms HBGary and HBGary Federal, Sony 20th Century Fox, PBS, Infragard, Nintendo, the UK's National Health Service, the Arizona State Police, and News International, according to Ars Technica.
Additional charges of conspiracy to perform distributed denial of service (DDoS) attacks against a number of agencies were not brought to action by London's Crown Prosecution Service, but were left on file, Ars said.
LulzSec members and co-conspirators Jake "topiary" Davis, 20, and Mustafa "tflow" Al-Bassam, 18, earlier pleaded guiltyto all charges. All three will be sentenced on 14 May, along with Ryan Cleary, a 21-year-old hacker who last year entered a guilty plea in six connected charges, including constructing a botnet, making it available to others, hacking into Pentagon computers, and performing a DDoS attack against DreamHost.
In March 2012, the FBI snagged six Anonymous and LulzSec hackers involved with the attacks, including Hector Xavier Monsegur, a member of the group who cooperated with the government and pled guilty to 12 counts of various crimes. Darren Martyn, Donncha O'Cearrbhail, and Jeremy Hammond were also arrested and charged by the feds for various cyber crimes committed between December 2010 and June 2011.
