The FBI has recently formed a secretive surveillance unit with an ambitious goal: to invent technology that will let police more readily eavesdrop on Internet and wireless communications.

The establishment of the Quantico, Va.-based unit, which is also staffed by agents from the U.S. Marshals Service and the Drug Enforcement Agency, is a response to technological developments that FBI officials believe outpace law enforcement’s ability to listen in on private communications.

While the FBI has been tight-lipped about the creation of its Domestic Communications Assistance Center, or DCAC — it declined to respond to requests made two days ago about who’s running it, for instance — CNET has pieced together information about its operations through interviews and a review of internal government documents.

The center represents the technological component of the bureau’s “Going Dark” Internet wiretapping push, which was allocated $54 million by a Senate committee last month. The legal component is no less important: as CNET reported on May 4, the FBI wants Internet companies not to oppose a proposed law that would require social-networks and providers of VoIP, instant messaging, and Web e-mail to build in backdoors for government surveillance.

During an appearance last year on Capitol Hill, then-FBI general counsel Valerie Caproni referredin passing, without elaboration, to “individually tailored” surveillance solutions and “very sophisticated criminals.” Caproni said that new laws targeting social networks and voice over Internet Protocol conversations were required because “individually tailored solutions have to be the exception and not the rule.”

Caproni was referring to the DCAC’s charge of creating customized surveillance technologies aimed at a specific individual or company, according to a person familiar with the FBI’s efforts in this area.
