The Problem
More and more each day competitors,
ex-associates, new start-up ventures, and
unscrupulous individuals are using
electronic eavesdropping as a way to
gather information that could seriously
damage your business.
"Bugs"
telephone taps and video transmitters
(above) are readily available that can
compromise your business secrets for as
little as $30.00. The manufacture, sale,
installation, and monitoring of these
devices is a multi-billion dollar
industry in North America.
Unless you are a law enforcement agency
with an Order or Warrant for a wire tap,
it is a criminal offence to record the
conversations of two or more persons
without their consent.
How Do You Know If You're
Bugged ?
-
Confidential
information seems to be getting
out to competitors.
-
Competitors
seem to be just one step ahead
all of the time.
-
Your
office was broken into yet very
little or nothing was taken.
Sockets or switches show signs of
being moved slightly, ie: the
wallpaper may be disturbed.
-
Vehicles
parked near to your premises,
that appear to be empty.
-
Your
telephone rings but no one speaks
or you just hear a short tone.
-
Unusual
sounds (crackling, clicks, volume
changes) on your telephone
handset.
-
Indications
that your handset may have been
exchanged, ie: numbers in memory
may be lost.
-
Repairers
or utility companies turn up to
carry out work when they have not
been called.
-
Furniture
or items appear to have been
disturbed.
-
Interference
on your radio or television.
-
Unexplained
brick or plaster dust on floor.

Kevin Bousquet Looking &
Listening for RF Devices
The RF Sweep
& Spectrum Analysis
The most
commonly and widely used of all the
devices is the RF (Radio Frequency)
transmitter bug. These devices are
inexpensive easy to use and require no
specialized receiving equipment a simple
AM or FM radio can be used to monitor the
bug. Due to their low cost, there is very
little incentive to recover these devices
once planted.
The
Spectrum Analysis (photo above) we use to
detect RF devices is capable of
monitoring frequencies up to 36 Gigaherts. This will also include very
low frequency (VLF) devices which
transmit on frequencies down to 15
Kilohertz.

Devices through the Power Lines
Power Line
Analysis - Hard Wire Bugs
The next method is often known as the
"wire tap" or a "hard wire
bug". The wiretap will use any
existing wiring in the home or office ie:
the electrical plugs (see photo above),
alarm systems or even the telephone
wiring. This is similar a typical baby
monitor situation where you plug the
transmitter into one room and the receiver
in the other.
Many think that telephones
are only a security risk when being used
but a simple modification to the handset
can leave the microphone connected, even
when the phone is not in use.
