Following the arrest of a Freedom Hosting service provider supervisor in Ireland, whom law enforcement has referred to as "the largest facilitator of child porn on the planet," some reports have surfaced of a JavaScript exploit of vulnerabilities in the anonymizing Tor Browser bundle. The exploit compromises Firefox, and forces the browser to send the computer's regular IP address to a Verizon IP address along with information on Tor sites visited to a data farm located in Reston, Virginia that is associated with US law enforcement.
