Wireless
tapping device can be made its out look unlimitedly. It can
be harbored in the package of the gift, and can be controlled
by wireless controller. Besides, it can be hided any objects
that we normally use for our daily lives, such as a flowerpot,
a calculator, a ballpoint pen, a fire detector, a remote controller,
a telephone connector, a beeper, a and a mobile phone.
A. Wireless bug technology
Wireless tapping technology is highly developed, so
it is extend to Very Low Frequency, Extremely High Frequency,
and Digital area. In fact, its operation methods are incredibly
sophisticated. Here, we describe the practical examples of wireless
tapping devices.
Throw
down Bug
It is designed that
they let the detectors find the bug, and believe detection is
over. However, the real one is hided more deeply.
Snuggled Bug
Its
frequency range is almost same with the public broadcasting
area, so that the detectors confound it. Audio information is
compressed and saved for 3 to 4 hours, and it is transmitted
in certain time immediately. It usually does not appear its
frequency.
Frequency
Hopping Bug
It utilizes for
security issues. The certain range of frequency is changed to
the different amount. There is, for instance, the one which
has 50MHz but happen 500 times per second for frequency modification.
Carrier Current
Voice
signal is transmitted by the electric wires or telephone cables
through carrier wave. This technique is accepted for the number
of methods, so that it can be re-transmitted by wireless receiver
and recorder in the different location.
Laser Transmission
Laser is
non visible ray to be transmitted the voice signal. Laser is
shot form the out side of the window. The vibration on the window
is examined by the laser, and it is converted to the voice.
B. Wired Bug Technology
There is everywhere to
be exposed in the path like the inside of the telephone, the
wire path, the unit box, the electric pole, etc. Not just around
the target, but also the out of the way place can be eavesdropped.
Here, the practical examples are described in detail.
Series bug
The bug is directly connected on the side to the telephone line,
so that voice signal is transmitted wirelessly.
Parallel Bug
The bug is connected in parallel. It works by the current flow
and the sound. Power supply is necessary.
Inductive Pickups
When the telephone is on, the difference of the electric magnetic
field is examined to eavesdrop.
Slave Bug
When the target person uses the telephone, the system calls
to the receiving location for bugging.
Tone Activated Bug
Wherever the phone line conversation is possible, it calls to
the target telephone, and transmitted certain frequency for
activating tone. Then, it is bugging with installed micro phone.
Hook switch Bypasses
Resistors, condensers, and operation maintenance diode are connected
on the hook switch. So, the voice signal is tapping via the
phone.
Extra wire bug
On the Extra wire connected to the telephone, micro elements,
the inside of the receiver microphone, micro phone on the speaker
phone, speaker, and linker, are connected for tapping.
T1 and E1 Circuit Bug
The monitoring function of the device for checking the DID circuit,
T1 and E1, on the small and middle size of the switch boards
are utilized for bugging.
¡Ø T1 is the north American type with 24 voice channels
¡Ø E1 is the European type with 30 voice channels.
Tape Recorder
The recorder is connected in parallel. When the phone line works,
the device is automatically operated.
C. Key Phone System and Private Branch Exchange
Here, the practical instances of bug with the key-phone system
and private branch exchange are described in detail.
Executive override, Barge-in
When the target is on the line, it intrudes into the line with
the program which design for not to recognize.
Bridged Extension
Instead of the physically direct connection, the line, trying
to contact to the target line, is connected and accessed on
the programming environment.
Connection via Voicemail
The recorded message on the voice mail is easily eavesdropped
by it secret number. |
