Revealed: WikiLeaks Volunteer Doubled as FBI Mole

For three months in 2011 — less than a year after WikiLeaks released its most famous series of documents leaked by Bradley Manning — a mole inside the non-profit organization provided the FBI with chat logs, videos and other data from Julian Assange and his associates

The mole's name is Sigurdur "Siggi" Thordarson, a longtime Icelandic volunteer working for WikiLeaks at the time. On Thursday, Wired's Kevin Poulsen revealed Thordarson's double role as a close Assange protégé and a paid informant working for the United States government in its WikiLeaks investigation.
