A member of the hacktivist group LulzSec pleaded guilty to one count of computer hacking Tuesday.
Ryan Ackroyd, 26, pleaded guilty to carrying out an unauthorized act to impair the operation of a computer, contrary to the Criminal Law Act 1977, said a Crown Prosecution Service spokesperson.
As a result, the 26-year-old will not face trial for a separate charge of involvement in a number of distributed denial of service (DDoS) attacks.
Ackroyd faces sentencing alongside fellow LulzSec members Mustafa Al-Bassam and Ryan Cleary next month.
Al-Bassam and Davis both admitted involvement with LulzSec in 2012, pleading guilty to hacking and launching cyber attacks.
LulzSec is an offshoot group of the Anonymous collective that started up in May 2011.
The group originally mounted a “50-days of Lulz” campaign that saw it target numerous government and private sector groups, starting with Sony.
The attack on Sony was to “punish” it for its poor security and treatment of jailbreaker GeoHotz, who hacked the company’s PlayStation 3 games console to let users run other operating systems on it.
Other targets included Rupert Murdoch’s News International, the UK’s Serious Organized Crime Agency and U.S. Central Intelligence Agency (CIA).
