Article Summary   by:saji

This is an extract from the ‘The New Indian Express’.








The project done by four
Engineering students from Kasargod LBS Engg College based on UVAH (Universal
Video Display Authentic Hacking Box) was motivated by the idea “Van Eck
Phreaking”. This idea was generated
decades ago by Win Van Eck. In 1985 US and USSR used this tech to leak
important military documents.





The concept of the project is
that electron beam scanners, scans the computer or TV monitor when it displays
the visuals. The scanner emits the radiation, which can be received by antennae
directed towards the monitor. The signals are then amplified and decoded using
video demodulator. The demodulated data can be converted to visible images and
displayed to the computer or TV monitor providing horizontal and vertical
synchronization.





With their miniature project they
can collect data from radiation emitted by PC monitors within ten meters radius
and reproduce in their own monitor. This came handy for making spy instruments.
The sale was restricted to their own countries only for this instrument. To
prevent this hacking, US official had
developed standardization for monitors named TEMPEST (Transient Electro
Magnetic Pulse Emanation standards). Only TEMPEST are used in the defense to
fool proof pilfering. Indians do not have TEMPEST monitors, hence almost all
the monitors are subjected to be hacked.
