Cellular carrier giving FBI unfettered access

Computer security analyst Babak Pasdar says that a major mobile telecommunications carrier has a built-in backdoor that provides an undisclosed third-party with unfettered access to its internal technical infrastructure, including the ability to eavesdrop on all calls through its network.

Pasdar was instructed not to migrate the traffic for one particular DS-3, which was referred to as the "Quantico Circuit" by consultants who worked closely with the carrier (the FBI Academy is based in Quantico, Virginia).

When Pasdar insisted that the Quantico Circuit should at least have the minimum level of security access logging if not access control, the consultants called the company's Director of Security, who threatened Pasdar, telling him that he would be replaced if he didn't forget about the circuit and continue with the migration.

Wired's Threat Level blog connected the pieces and points us to the 2006 wiretapping lawsuit against the telcos, which alleges that Verizon "has engaged and maintained and still does maintain a high speed data transmission line from its wireless call center to a remote location in Quantico, Virginia, the site of a U.S. government intelligence and military base."

This is particularly disturbing if the recipient of the Quantico Circuit is the FBI, because the agency has a long history of intelligence abuses and has been found to have a serious lack of meaningful internal oversight.
