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, according to a computer security consultant who says he worked for the carrier in late 2003.

"What I thought was alarming is how this carrier ended up essentially allowing a third party outside their organization to have unfettered access to their environment," Babak Pasdar, now CEO of New York-based Bat Blue told THREAT LEVEL. "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. That suit names Verizon Wireless as the culprit.

Pasdar has executed a seven-page affidavit for the nonprofit Government Accountability Project in Washington, which on Tuesday began circulating the document (.pdf), along with talking points (.doc), to congressional staffers hashing out a Republican proposal to grant retroactive legal immunity to phone companies who cooperated in the warrantless wiretapping of Americans.
