A 26-year-old Doncaster man has pleaded guilty to hacking websites of major institutions including the National Health Service, Sony and News International.
Ryan Ackroyd, of Oak Road, Mexborough, was due to stand trial charged with taking part in a string of cyber attacks, but has pleaded guilty to one charge of carrying out an unauthorised act to impair the operation of a computer, contrary to the Criminal Law Act 1977.
Southwark Crown Court heard he admitted being a member of hacking group LulzSec, acting as a “hacker” to access websites for Sony, 20th Century Fox, the NHS, Nintendo, the Arizona State Police, and News International, between February and September 2011.
Prosecutor Sandip Patel told the court: “He was the hacker, so to speak, they turned to him for his expertise as a hacker”, and said Ackroyd admitted using the persona of a 16-year-old girl Kayla on the site.
He will be sentenced on May 14 and the court heard prosecutors are not planning to pursue other charges against Ackroyd.
