An accused member of Anonymous offshoot LulzSec has pleaded guilty to participating in an extensive hack of Sony Pictures Entertainment in 2011. Reuters has reported that in a deal with prosecutors, Cody Kretsinger pleaded guilty to one count each of conspiracy and unauthorized impairment of a protected computer. We still don't have any information on the deal, but it was apparently enough to get him to reverse an earlier "not guilty" plea.
Kretsinger, allegedly known as "recursion" within LulzSec, was accused last year of obtaining information from Sony and passing it along to other members. Kretsinger was the first alleged member of LulzSec to be apprehended, a list that is now significantly longer after last month's arrests.
Correction: He was not accused of being involved in the PlayStation Network hack, also from 2011.
