Wiretapping
How it works


When you open up a phone, you can see that the technology inside is very simple. The simplicity of design makes the phone system vulnerable to surreptitious eavesdropping.

Wiretapping occurs all the time in espionage and crime movies. Spies and gangsters know the enemy is listening, so they speak in code over the phone and keep an eye out for bugs. In the real world, we may not think much about wiretapping. Most of the time, we assume our phone lines are secure. And in most cases, they are, but only because nobody cares enough to listen in. If people did want to eavesdrop, they could tap into almost any phone line quite easily.

a simple wiretapping method

This consists of a hard wire connection where you can hook up more loads (components powered by the circuit) anywhere along the line. This is what you're doing when you plug an extra phone into a jack in your house.

This is a very convenient system, because it's so easy to install and maintain. Unfortunately, it's also very easy to abuse. The circuit carrying your conversation runs out of your home, through your neighborhood and through several switching stations between you and the phone on the other end. At any point along this path, somebody can add a new load to the circuit board, in the same way you can plug a new appliance into an extension cord. In wiretapping, the load is a device that translates the electrical circuit back into the sound of your conversation.

This is all wiretapping is -- connecting a listening device to the circuit carrying information between phones.

The wiretapper could stay with the connection at source or set up a voice activated recording device. Unfortunately, this will have a limited space, so an RF bug is a solution.

 


RF bug

snug as a bug


This phone receiver has been tapped with a tiny bug (the black cylinder with the metal coil on top). The red and black wires connect the tap to the circuit running through the receiver. The bug's radio transmitter broadcasts the electrical signal in this circuit to a nearby radio receiver.

Of course, hanging out in a van and listening to someone's phone conversations is completely illegal for a civilian. But the law for the government is a little murkier.

Internet wiretapping

This is either intercepting e-mails at the ISP or picking up the mobile signals from your pc mobile connection.
