- <p> Besides following them, bugging them, wiretapping them and
- digging through their trash, the FBI got the goods on the alleged
- CIA mole and his wife by conducting "electronic surveillance
- of [Rick] Ames' personal computer," according to the affidavit.
- The FBI won't say exactly how it did this, but electronic experts
- have some intriguing ideas that illustrate the advanced state
- of computer snooping.
- </p>
- <p> One way to look into a suspect's computer is remote surveillance.
- Parked just down the block, agents are able to pick up the electromagnetic
- waves that dance across a suspect's computer screen and convert
- them back into characters and words on a monitor. They can read
- everything the suspect is writing. While imaginative, this method
- is unpopular with law-enforcement authorities because they have
- to sit and watch the TV screen for weeks or review hours of
- videotape to see everything a suspect is doing.
- </p>
- <p> FBI agents probably tapped into Ames' computer with a variation
- on old-fashioned bugging. One way would have been to enter his
- home and plant a device in the computer that would broadcast
- every keystroke. A more efficient method would have been to
- plant a bug enabling them to turn on the computer from another
- location, call up the internally stored files and transmit them
- by either radio or telephone modem to the FBI's waiting machines;
- the computer and modem would have been turned off by a remote
- signal. While in his house, the FBI might also have copied the
- diskettes he had on hand. And, surveillance experts say, they
- could have done all this without the suspect's ever knowing
- they had entered his computer.
