How the FBI Wiretap Network Works

So have you noticed lately that there is more noise on the phone? Strange clicks and silent gaps? Maybe that file you are downloading is taking more time than it used to. Or, you are having connection problems with VOIP phones like Vonage? Having a little more of a delay in your push to talk walkie talkie feature?

If you are, it may be the Fascist Feds snooping on you. Better start using some encryption. Death to the Empire!!!

The FBI has quietly built a sophisticated, point-and-click surveillance system that performs instant wiretaps on almost any communications device, according to nearly a thousand pages of restricted documents newly released under the Freedom of Information Act.

The surveillance system, called DCSNet, for Digital Collection System Network, connects FBI wiretapping rooms to switches controlled by traditional land-line operators, internet-telephony providers and cellular companies. It is far more intricately woven into the nation's telecom infrastructure than observers suspected.

It's a "comprehensive wiretap system that intercepts wire-line phones, cellular phones, SMS and push-to-talk systems," says Steven Bellovin, a Columbia University computer science professor and longtime surveillance expert.

DCSNet is a suite of software that collects, sifts and stores phone numbers, phone calls and text messages. The system directly connects FBI wiretapping outposts around the country to a far-reaching private communications network.

Many of the details of the system and its full capabilities were redacted from the documents acquired by the Electronic Frontier Foundation, but they show that DCSNet includes at least three collection components, each running on Windows-based computers.

The $10 million DCS-3000 client, also known as Red Hook, handles pen-registers and trap-and-traces, a type of surveillance that collects signaling information -- primarily the numbers dialed from a telephone -- but no communications content. (Pen registers record outgoing calls; trap-and-traces record incoming calls.)

DCS-6000, known as Digital Storm, captures and collects the content of phone calls and text messages for full wiretap orders.

A third, classified system, called DCS-5000, is used for wiretaps targeting spies or terrorists.

What DCSNet Can Do

Together, the surveillance systems let FBI agents play back recordings even as they are being captured (like TiVo), create master wiretap files, send digital recordings to translators, track the rough location of targets in real time using cell-tower information, and even stream intercepts outward to mobile surveillance vans.
