A member of the LulzSec hacker group was sentenced to one year in prison for breachingSony's servers in June 2011, Reuters reports.

Cody Kretsinger, who pleaded guilty in April 2012 to charges of conspiracy and authorized impairment of a protected computer, will also have to perform 1,000 hours of community service once he gets out of prison.

The sentence is a part of a plea bargain that helped Kretsinger — also known by his online moniker "Recursion" — avoid a maximum sentence of 15 years in prison.

The Sony Pictures hack, which exposed more than 1 million user accounts, was the largest in a long series of hacks performed by members of LulzSec. The group took credit for the attack, posting the stolen user info on its (now defunct) website.

The attack caused Sony more than $600,000 in damage, prosecutors said.
