The final member of the defunct hacktivist group LulzSec has pleaded guilty to one count of computer hacking.
A Crown Prosecution Service spokesperson confirmed to V3 that Ryan Ackroyd, 26, had pleaded guilty to carrying out an unauthorised act to impair the operation of a computer, contrary to the Criminal Law Act 1977 on Tuesday.
The 26-year-old will not face trial for a separate filing accusing him of involvement in a number of distributed denial of service (DDoS) attacks, though.
Ackroyd will be sentenced 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 was a splinter group from the Anonymous collective that appeared in May 2011.
The group originally mounted a "50-days of Lulz" campaign that saw it target numerous government and private sector groups, which started with Sony.
The attack on Sony was reportedly done to "punish" it for its poor security and treatment of jailbreaker GeoHotz, who famously hacked the company's PlayStation 3 games console to let users run other operating systems on it.
Other famous targets included Rupert Murdoch's News International, the UK's Serious Organised Crime Agency and US Central Intelligence Agency (CIA).
At the time of publishing the US London Embassy had not responded to V3's request for comment whether it would seek the extradition of any of the hackers.
However, in the past the US government has not sought the extradition of people who are already facing legal action in their country of residence.
