Former FBI special agent Christopher Tarbell was heavily involved in the tracking and arrest of two of the most infamous figures in cyberspace – Sabu, of the hacktivist collective Anonymous (and at one point the most influential hacker in the world), and Dread Pirate Roberts, the man behind the deep web’s infamous Silk Road—“the most sophisticated and extensive criminal marketplace on the internet.” Exclusively represented by Leading Authorities speakers bureau, Tarbell has extensive expertise in cyber security and computer forensics. A former member of the FBI’s preeminent cyber crime squad, he is the man about whom even the most notorious cyber criminals have nightmares.
