On Wednesday, the Australian Federal Police (AFP) arrested and charged a 24-year-old man from New South Wales who claims to be the leader of LulzSec. The man, who has not yet been named publicly by the authorities, is believed to be the person behind the online moniker “Aush0k.” Other Australian media have named him as Matthew Flannery, who worked for Sydney-based firm Content Security. According to the Sydney Morning Herald, Flannery was fired by Content Security on Tuesday, following his arrest.

Specifically, the suspect was charged with two counts of “unauthorised modification of data to cause impairment,” and one count of “unauthorised access to, or modification of, restricted data.” Authorities believe that Flannery set up some type of remote and hidden access to a government website that the AFP did not specify, although they did say it was not an Australian federal site.

Collectively, these offenses carry a maximum penalty of 22 years in prison. Flannery is scheduled to appear in Woy Woy Local Court on May 15, 2013.

Federal authorities allege that because of Flannery's job, he had access to sensitive government information. Flannery’s former employer, Content Security, said that he had no such access.

"Flannery did not and does not have access to any customer information that was or could have been used to carry out any malicious activity or compromise systems," Content Security said in a statement to the Herald.

Just last week, a California judge sentenced fellow LulzSec member Cody Kretsinger, nicknamed "Recursion,” to one year and one day in prison. Also earlier this month, three UK-based LulzSec members pleaded guilty to related crimes in a London courtroom. As of June 2011, the hacktivist group said publicly that it had disbanded.
