Everyone wants to know who the person was which helped the Hacker Sabu to take down the infamous hacktivist group. The leaked documents refer to the second RAT as CW-1, CW-2. CW stands for confidential witness. This information has been provided through the leaked documents which have been published via theregister website.
The documents don’t reveal the name of the second informant, but the Daily Dot suggests this party might have been subjected to arrest in Ohio in June 2011 prior to informing on British LulzSec member Ryan Cleary, as well as implicating Ryan “Kayla” Ackroyd in a December 2010 hack against Gawker.
Theregister claims that a Twitter update appeared during the time of the arrests.
A Twitter update from around this time from LulzSec denouncing “M_nerva” for helping the Feds supports this theory.
One of 12 leaked documents (PDF) provides justification for a search warrant against a Facebook profile, “lesmujahideen”, linked to Monsegur. At the time of the warrant on 7 June 2011, the Feds already had Monsegur’s IP address, linking illegal actions online back to an internet connection in a New York apartment. Investigators made this crucial IP address link in April 2011, earlier than previously publicly suspected.
Another hacking suspect – Jeremy Hammond (AKA Anarchaos), 29, of Chicago, Illinois, received a far tougher sentence. Hammond was jailed for 10 years for a hack onsecurity intelligence outfit Stratfor that took place in December 2011. As many as 60,000 credit card numbers stolen as part of the hack were used to make fraudulent donations to worthy causes.
