Erris's Journal: The FBI's Unlimited Back-Door to Your Cell Phone.

A security consultant whistle blower claims a U.S. government office in Quantico, Virginia, has direct, high-speed access to a major wireless carrier's systems, exposing customers' voice calls, data packets and physical movements to uncontrolled surveillance.

Pasdar tumbled to the surveillance superhighway in September 2003, when he led a "Rapid Deployment" team hired to revamp security on the carrier's internal network. He noticed that the carrier's officials got squirrelly when he asked about a mysterious "Quantico Circuit" -- a 45 megabit/second DS-3 line linking its most sensitive network to an unnamed third party.

"I wanted to put some access controls around it; they vehemently denied it. And when I wanted to put some logging around it, they denied that." Pasdar won't name the wireless carrier in question, but his claims are nearly identical to unsourced allegations made in a federal lawsuit filed in 2006 against four phone companies and the U.S. government for alleged privacy violations.
