The act of eavesdropping is a very real threat in today's world.
Each one of the items on this page could be used to conceal an electronic listening device (bug) or even a pinhole camera. A bug can be implanted in almost anything, turning it into a threat: a light switch, book, the clock on your desk or wall, a lamp, pen, calculator, computer speakers and radios are all likely candidates. Bugs can be placed in gifts. What about your fax machine and/or photocopier? Bugs can be installed in these machines in order to intercept and transmit images.
