An alleged member of LulzSec was arrested yesterday on charges that he was involved in a 2011 cyber attack on Sony Pictures Entertainment.

"Raynaldo Rivera, 20, of Tempe, Arizona, surrendered to U.S. authorities in Phoenix six days after a federal grand jury in Los Angeles returned an indictment charging him with conspiracy and unauthorized impairment of a protected computer," writes Reuters' Steve Gorman. "If convicted, Rivera faces up to 15 years in prison."

"LulzSec in June of last year posted statements online saying it had broken into SonyPictures.com and downloaded unencrypted personal information, including passwords, e-mail addresses and dates of birth from 1 million user accounts," writes Businessweek's Edvard Pettersson.

"The group's members anonymously claimed responsibility for the attack known as an 'SQL Injection,' a hacking technique used to steal information off a database," writes The Los Angeles Times' Andrew Blankstein. "Rivera, who allegedly used names including 'neuron' and 'royal,' is accused of using a proxy server to remain anonymous or hide his Internet Protocol -- or IP -- address, federal authorities said."

"Another LulzSec member, Cody Kretsinger, 24, also of Tempe, was arrested last year and pleaded guilty in April to similar charges related to the same attack," writes Threatpost's Anne Saita. "He's scheduled to be sentenced Oct. 25."
