Warning
Signs of Covert Eaves Dropping or Bugging

If several of these
warning signs apply to you then it would be a very good idea to immediately
contact VAN STADEN FORENSIC SERVICES and schedule an inspection, as you
may be the target of covert eavesdropping or bugging activities.
When contacting please
remember not to call from any suspect area or to use any suspect telephone.
- Others know your
confidential business or professional trade secrets.
This is the most common indicator; theft of confidential information
is a multi-Million Rand industry in South Africa. Often the loss of
your secrets will show up in very subtle ways.
- Secret meetings
and bids seem to be less than secret.
Confidential meetings and bids are very popular targets for corporate
spies. How would you like the plans for the corporate takeovers you’re
planning to become public knowledge? Would copies of your product designs
be of any use to your competitors? How would you like to read about
your company plans in the media? Competitors often hand over documents
and information to news-starved journalists.
- People seem to
know your activities when they shouldn't.
- You have noticed
strange sounds or volume changes on your phone lines.
Commonly caused by an amateur eavesdropper when they attaches the actual
wiretap, or similar listening device. Surveillance devices often cause
slight anomalies on the telephone line.
- You have noticed
static, popping, or scratching on your phone lines.
This is caused by the capacitive discharge, which occurs when two conductors
are connected together (such as a bug or wiretap on a phone line). This
is also a sign that an amateur eavesdropper or poorly trained spy is
playing with your phone lines.
- You can hear sounds
coming from your phones handset when it's hung up.
Typically caused by a hook switch bypass, which turns the telephone
receiver into an eavesdropping microphone (and also a speaker). There
is probably somebody listening to everything you say or do within six
metres of the telephone (if this is happening).
- Your phone often
rings and nobody is there, or a very faint tone, or high-pitched squeal
and beep are heard.
This is a key indicator of a slave device, or line extender being used
on your phone line. This is also a key indicator of a harmonica bug,
or infinity transmitter being used.
- Your radio has
suddenly develops strange interference.
Many amateur eavesdropping devices use frequencies within the FM radio
band; these signals tend to "quiet" a FM radio in the vicinity
of the bug. Look for the transmissions at far ends of the FM radio band,
and at any quiet area along the FM band. If the radio begins to squeal
then slowly move it around the room until the sound become very high
pitched to locate the bug (this is referred to as feedback detection
or loop detection and will often locate the bug). The "Stereo"
function should be turned off so the radio is operating in "Mono"
as this will provide a serious increase in sensitivity.
- Your television
or radio has suddenly developed strange interference.
Television broadcast frequencies are often used to cloak an eavesdropping
signal, but such a devices also tends to interfere with television reception
(usually a UHF channel). Televisions also "suck in" a lot
of RF energy and because of this are very sensitive to any nearby transmitters.
A small handheld television with a collapsible antenna may be used to
sweep a room. Carefully watch for interference around channel numbers
2, 7, 13, 14, 66, 67, and 68, as these frequencies are popular with
eavesdroppers.
- You have been the
victim of a burglary, but nothing was taken.
Professional eavesdroppers often break into a targets home or office,
and very rarely leave evidence of the break-in; however, occupants of
the premises will often "pickup on something not being right"
such as the furniture being moved slightly.
- Electrical wall
plates appear to have been moved slightly or "jarred".
One of the most popular locations to hide eavesdropping devices is inside,
or behind electrical outlets, switches, and lighting fixtures. This
requires that the wall plates be removed. Look for small amounts of
debris located on the floor directly below the electrical outlet. Also,
watch for slight variations in the colour or appearance of the power
outlets and/or light switches as these are often swapped out by an eavesdropper.
- A small-sized discoloration
has suddenly appeared on the wall.
Tell tale sign that a pinhole microphone or video camera has been recently
installed.
One of your vendors just gave you any type of electronic device such
as a desk radio, alarm clock, lamp small TV, boom box, CD player, and
so on.
Many of these "gifts" are actually Trojan horses, which contain
eavesdropping devices.
- The Smoke Detector,
Clock, Lamp, or Exit Sign in your office or home looks slightly crooked,
has a small hole in the surface, or has a quasi reflective surface".
These items are very popular concealment for covert eavesdropping devices.
Often when these devices are installed at a target location they are
rarely installed straight. Also watch out for things like this that
"just appear", or when there is a slight change in their appearance.
- Certain types of
items have "just appeared" in your office of home, but nobody
seems to know how they got there.
Typical items to watch for and beware of are: Clocks, Exit Signs, Sprinkler
Heads, Radios, and Lamps.
- White dry-wall
dust or debris is noticed on the floor next to the wall.
A sign that a pinhole microphone or video camera may have been installed
nearby. It will appear as if someone has dropped a small amount of powdered
sugar either on the floor, or on the wall.
- Small pieces of
ceiling tiles, or “grit” are noticed on the floor, or on
the surface area of your desk.
Prime indicator that a ceiling tile has been moved around, and that
someone may have installed a hidden video camera or other eavesdropping
device in your office or near your desk. Also watch for cracks in the
ceiling tiles and amateur spies always tend to crack or damage acoustical
tiles.
- You notice that
"TELKOM" trucks and utilities workers are spending a lot of
time near your home or office doing repair work.
Telephone, cable, plumbing, or air conditioning repair people show up
to do work when no one called them.
A very common ruse which eavesdroppers use to get into a facility is
to fake a utility outage, and then show up to fix the problem. While
they are fixing "the problem" they are also installing eavesdropping
devices.
- Service or delivery
trucks are often parked nearby with nobody in them.
These vehicles are commonly used as listening posts, be very cautious
of any vehicle, which has a ladder or pipe rack on the roof. Also, be
wary of any vehicle, which has tinted windows, or an area, which you
cannot see though (like a service van). The listening post vehicle could
be any vehicle from a small UNO, Panel Van, Bakkie, Mini-Bus, or Cargo
Van. Look for any vehicle, which could conceal a person in the back
or has tinted windows.
- Your door locks
suddenly don't "feel right", they suddenly start to get "sticky",
or they completely fail.
Prime evidence that the lock has been picked, manipulated, or bypassed.
Always use 5-lever Lock. Use good quality window bars on all windows,
and a good quality door bar on all doors not used as a primary entry
doors.
- Furniture has been
moved slightly, and no one knows why.
A very popular location for the installation of eavesdropping device
is either behind, or inside furniture (couch, chair, lamp, etc.) People
who live or work in a targeted area tend to notice when furnishings
have been moved even a fraction of an inch. Pay close attention to the
imprint which furniture makes on rugs, and the position of lamps shades.
Also watch the distance between furniture and the wall as eavesdroppers
are usually in a hurry and rarely put the furniture back in the right
place.
- Things "seem"
to have been rummaged through, but nothing is missing (at least that
you noticed).
A "less than professional spy" will often rummage through
a targets home for hours, but very rarely will they do it in a neat
and orderly fashion. The most common "rummaging" targets are
the backs of desk drawers, the bottom of file cabinets, closets, and
dresser drawers.
