Again, listening to whatever RF emissions come out of a computer
is an exercise in utter time-wasting. There's nothing there that the
human ear -- or even another computer -- can make any sense of.


actually computers and associated equipment can be " easily "
eavesdropped upon ..and a HUGE worldwide industry is based
upon this process. the obvious ways of tapping LAN , WANs, and
telco equipment is one way ... BUT RF and IR ( from pannel mounted
LEDS are other less well know ways.

the most common ways to eavesdrop on computers via RF or IR are to
listen to the immensely powerful raster scan from a computer CRT.
these can be eavesdropped upon from several blocks away with
with a directional antenna. also , optical eavesdropping on pannel
mounted LEDS ( like on a router or other mainframe items ) is another
choice. ( see one through a window !! )

type : eavesdropping on computers " into Google for over 52,000
hits and some eye popping information. ( or : RF eavesdropping on
computers " )

" war driving " has been a popular computer eavesdropping and hacking
hobby for some time ... and it isn't even illegal yet. but many
people add to this type of RF eavesdropping the additional deminsion
of just remote monitoring the CRT display to get easier info and
insight into the " marks " activities. VERY popular with some
detective agencies these days.
( type wardriving into Google too , or even ebay for the latest
equipment )

this type of computer eavesdropping vunerability is the chief reason
that ALL classified government and military installations have
conductive film on all outside facing windows. this is " absolutely "
required at civilian subcontractors too. even many computer hackers
line their room walls and windows with foil to stop outside discovery
of their activities . a really fun and interesting topic.

this stuff has been around for a decadeand half .... but still a very
modern topic.
