An IT professional working in Sydney has been arrested for hacking a government website as part of the LulzSec movement. The 24-year-old man, residing in Point Clare, was arrested at his workplace late yesterday. He claimed to be the leader of the hacker movement. 'Police say he was in a "position of trust" within the company and had access to information on government clients. The AFP says its investigation began less than two weeks ago when investigators found a government website had been compromised. The man has been charged with two counts of unauthorised modification of data to cause impairment and one count of unauthorised access to a restricted computer system. He faces a maximum of 12 years in jail.
