More info regarding FBI involvement:
Monsegur, 28, resident in New York City, was arrested by the FBI in June and has apparently acted as an informant against his crew since.
A copy of the indictment against Monsegur is available via krebsonsecurity.com here (PDF). He's charged with computer hacking, fraud and conspiracy charges stemming from attacks run by both Anonymous and LulzSec against numerous targets. According to the indictment, Monsegur's role in the alleged hacks was to look for vulnerabilities in websites that were then allegedly exploited either by him or other hackers.
Monsegur pled guilty on August 15, 2011 to three counts of computer hacking conspiracy, five counts of computer hacking, one count of computer hacking in furtherance of fraud, one count of conspiracy to commit access device fraud, one count of conspiracy to commit bank fraud, and one count of aggravated identity theft. He faces a maximum sentence of 124 years and six months in prison, according to the US Attorney.
Four others are also looking at some serious jail time. Where we (webmasters) have an interest is knowing some sophisticated hackers (new meaning instead of old meaning) won't be around to deface sites they disagree with...
