Who's Listening
------------------------------------------------------------
    Over the years, there has been a number of different studies and
discoveries that would alter personal and electronic security over time.
Devices able to "listen" to almost any form of communications have become
commonplace and are available "over the counter" from a varied number of
sources. Such units range from ten to fifteen dollars to expensive set-ups
that employ microwaves and lasers for the interception of almost any audio
signal in the spectrum. But now with somewhat needed protection from outsiders
in reference to this problem, a number of solutions have been put in place and
global protection is insured in environments that have such need. But the
coverage of environment has had a a major change in protective attention now
being place on the actual electronic emmanations that are so common with
todays standard electronic apparatus. Electronic telephones, computers and
communications networks, ATM's, radio and television stations are just part of
the overall electronic bubble that we have placed our society into with the
hopes of providing better and faster methods to make daily life a bit easier.
But with such a fragile structure as the electronic bubble, we have new
opportunities to discover secrets never before possible due to the lack of
technology. The same technology that helps us in one way or another may also
be helping others unbeknownist to those who are protecting the environment in
the first place. Signal leakage, either by design or by accident may lead to
total collapse of protective measures due to "wide open spaces" in the
protective sphere. In this particular paper, we will discuss the possible
problems of common office technology may bring in un-securing your
installation.      Our main focus will be in the areas concerning with the
emmanations or transmissions of "Tempest" frequencies. "Tempest", is the code
name given to a specfic area concerned with radio frequencies radiated by
computing equipment by the U.S. Dept. of Defense. This "concern" from such
equipment dates back to the late 50's. The concern ranged from the possible
interception of "informational information" by sources other than the intended
users of such. The problem is more easily reconigized by the current
requirement of normal electronic equipment having to conform to emmision
standards put forth by the Federal Communications Commission in reference to
the amount of electronic "noise" generated by common standard technology so
that such signals do not interfer with other such pieces of equipment or their
operations.   To describe in simple terms, Tempest frequencies are almost
straight through from commerical AM stations to the upper reaches of 600 Mhz.
They are generated or transmitted by any number of different common daily life
electrical and electronic systems. Your TV puts out one frequency, the stereo
another, the common electronic telephone, cordless phones still another, the
microwave oven puts out another and the wireless alarm does it to, and story
goes on. So just as all of these pieces of equipment emmit a signal, so does
the personal computer.  We will describe two possible examples of such
informational information and the abilty for some with directed intent to
cause potentially fatal results due to the use of directed "noise". It should
be noted that the current specifications for "Tempest" approved systems is
considered classified by the DOD and these specs were not available to the
author, but if one was to look at the specs for normal computing equipment and
reduce the allowed emmission output by at least 50 percent, that may be a
realistic emmission standard accepted by the DOD.

Example 1:
"We had better "Czech" this out!
 -------------------------------

In 1987, a very strange occurence concerning forgein nationals from an Eastern
bloc nation entered this country in a large camper-like truck via the border
checkpoint at Niagra Falls, New York. The visitors numbering 4 or 5, were in
the country under tourist visa's and were reported to be representives of the
countries automobile and truck industries here on a promotional tour to
garnner interest in their exportable products. The one problem with the
"visitors" is that none of them had any connection with such industries in
their home country. In fact, the visitors were far from what they supposedly
represented. The group descripton read like a Whos' Who of mid-level
management of Eastern bloc intelligence operations. The group reportedly
consisted of a nuclear physists, a specialist in aerial map-making complete
with a small ultra-light powered aircraft, a communications and computer
expert and two communist party officals.    Over a 5 month period, the group
was reported to have visited 17 states looking at 40 to 48 sites dealing with
military and defense contractor sites. The vehicle and its occupants were
reportedly followed by over 100 agents of the FBI, NSA, Secret Service and
State department and at least one over flight of a military reservation was
reported. Even though the overflown site was not identified, one site was.
This site, was the "sensitive" naval communications center for the Pacific
Fleet located in San Diego. It was reported that the truck and it's occupants
were parked a few hundred yards from the facility for several days and
according to law, were in no violation of any current statute at the time. The
group was also at or around at the 2800 acre North Island Naval Air Station
based in Coronado, California. The spokesman for the base stated that you
could not see much of anything going on except for the take-off and landing of
aircraft which you could see from almost any place.    Common sense states
that you do not have to be inside the facility in either a physical or
electronic standpoint to collect information. You can park in any lot or
street close
enough to your supposed target and stick up your antennas. No property
violations, no photo restrictions to comply with, no restrictions at all
because you are sitting in a public place, parked or having coffee with your
"ears" on. A good example of such parking was
 reported in a paper published in Computers and Security 4, titled
Electromagnetic Radiation from Video Display Units: An Eavesdropping Risk? by
William Van Eck, copyright 1985. He stated that when they were conducting
their experiments in the open on public roadways, with a van and antenna
system that was quite noticable, no one asked what they were doing or had any
thought about the time spent doing such things.  The end of this particular
story is as follows: At the end of the suspect journey, the truck was searched
at the Nosgales, AZ border checkpoint and was then released. Nothing
considered illegal was found in the search and the truck and it's passengers
were released and entered Mexico. Now even though the truck was suspected of
performing passive "eavesdropping" operations, the federal goverment had no
legal right to hold either the truck or crew. And the possible intercepted
information was then released from the country. It should be noted that the
truck could have a number of standard "off the shelf" items. These items could
have consisted of 2 general coverage radios with a combined tuning range
between 100 Khz to 2 Ghz., an IBM personal computer clone, various cheap video
and signal enhancment equipment,
printers and modems, and other such complement devices.     None of the
equipment would be any "James Bond" type of gear and the basic suspected set-
up would cost the operation less than 10,000 dollars if budgeted correctly.
And if possible, use of other simple off the shelf type radios like the 200.00
unit available from Radio Shack that covers 150 Khz to 30 Mhz is not at all
unheard
of due to some budget constraints, and since most emmanated signals generated
by logical devices are within commerical AM and FM frequencies, the use of a
standard auto radio antenna would suffice to use as a pickup.    So the major
concern with such actions comes from the ability of simple equipment to
detect, register and decipher such emmanations with relative ease. The ability
of such persons and possible actions able to penetrate the electronic fog of
our society should be a clear distinct warning to those concerned with
security in general.  In addition to all of the above, the author contacted
various federal goverment agencies in reference to this information and was
told that they had
no knowledge of such an investigation and could not tell where such supposed
counter-intelligence operations were controlled from or who to contact in
reference to supplying such information. Current "Freedom of Information Act"
requests for information concerning this supposed federal project are
     underway.  An interesting note about filing the forms for access to
     information about the Czech incident is described to give guidance to
     others who may wish to investigate this incident and seek help from such
     elected officals. When the papers were filed for the desemenation of
     information through the Freedom of Information Act, members of the U.S.
     Senate and Congress were contacted in reference to this matter. The first
     contact was placed through Senator Arlen Spectors office in Philadelphia,
     Pa. We were first rebuffed by persons who refused to identify themselves
     with the statement " I am sorry, but that information is covered by the
     1974 Privacy Act, Click! Well we called back and informed the person who
     answered the call of the situation and then were re-connected and
     informed them that Czech citizens were not covered by US privacy laws and
     that there was no invasion of privacy. They called the FBI and asked if
they were the way such things were handled, and were told yes or no. But they
had no answer for any question put forward and said " They were sorry!", but
we don't know how to help you!. Our second contact to Senator Spectors office
in Philadelphia as in essance like the first, they would not assist nor would
explain why they took this position in the first pace. During our second
contact we spoke to a Miss or Mrs. Anderson. She stated that such requests
were not in the senator's perview and they could not assist in this matter.
When asked why
it as not in the senators preview, we were informed that they do not have to
give a response. When asked for an offical response, we were informed that no
offical response would be given. But as a side note, Senator Hienz office said
that they would forward the requests to Spectors office in Washington. One
other thought on this matter: I am sure that if the good senator wants to get
some information, his staff jumps through hoops to get him all he wants and
then
some! A pre-publish copy of this article will be delivered so that even he (or
his office staff, who were of no help at all due to a tough question placed to
them by a citizen) may learn of what may be going on in his own country. So
much for gaining assitance from a senator who sits on a judical panel. We
visited
next the office of John Hienz.     Again, funny looks about the Freedom of
Information Act and they hemmed and hawed at the questions presented. They
took the requests and said they would try and see what could be done. Our
final visit was to our local congressman, Tom Foglietta, whos office still
stated the 1974 Privacy law, but took the requests when presented in person.
It pays to visit your elected representives working areas. So much to do (if
you work there!) in
a goverment office. Other federal agencies including the FBI were most helpful
in complying with the requests. Of course we found this most interesting. Is
it so they could possibly reclassify the information to a "Secret" status
instead
of what it may be now.   Other agencies contacted in reference to FOIA
requests include the CIA, NSA, NRO, Customs, State Dept., Army Automated
Intelligence and Military Police, FBI, FCC .

Example 2:
"Breaker, Breaker, Wally Gator!"
 -------------------------------

     During the 70's, the United States had a short term love affair with the
Citizens Band radio. What were once clean channels were suddenly crammed with
persons who wanted to be able to communicate with any number of persons who
also had such capabilities. Suddenly, everyone had one of these radios in the
home or car and some were know to have both. Numerous persons ran such rigs
with varing illegal applications ranging from a lack of license to the intense
over powering
of such stations.   To give a brief explanation of CB's, we will keep it
simple.  CB's transmit in the upper reaches of 26 Mhz to 27 Mhz or 11 meters
band. CB's are allowed to operate with a maximum output of 5 watts radiated
power. Of
course this limited power was not sufficent for some users and the use of
linear amplifiers or "heat" was commonplace. Stations were known to be
transmitting 50 to 2 thousand watts to their antennas which in turn would
increase such signals to a power of over 2 hundred thousand watts. Some
operators were known to show the intense power outputs with the use of
flourescent lightbulbs and the abilty to "light" these tubes from a distance
without electrical connections with the amplified radiated power of their
antennas.  Some persons were known to have
full control of channels in their respective areas and would blank out anyone
who would not conform to the channels establised rules or procedures. Others
set-up pirate stations that would broadcast commerical music for all to hear
complete with news, weather and sports. Such actions would tie up frequencies
and caused a general crackdown by the FCC in the later years. But the problem
still continues and the FCC has all but given up on the idea of any
enforcement of regulations concerning such operations on the 11 meter or 27
Mhz band.  The craze of CB's left the general populace by the late 70's and
was back in the hands of those who would truely use such radios. Those who
would use such radios best known, would be the persons called truckers since
that is what they do.  They "truck" goods from one place to another and are
concerned with time and travel conditions as most of us are. The truckers
always had some "heat" on-
board for those times when they could not get their signal "out". It was and
still is considered an insurance policy by most who have this technology and
is
widespread in its use.   Now over time, with the continued expansion of these
radios, the truckers began to switch to amateur band radios in the 10 meter
band and were conversing just as before. Since the 10 meter band would permit
such radios and the increased power output, the switch to 10 meters was only a
matter of time. Now, it is reported that most truckers are using and abusing
such frequencies and their is little that can be done to stop such occurances
from happening. To add to all of the mess, such radios have the ability to
switch operating frequencies with the touch of a button. In brief, the 10
meter radios can switch to the 11 meter (CB) band with minor modifcations. And
back and forth
frequency hopping is as easy as tuning in the average auto radio.     One
other interesting aspect of these 10 and 11 meter radios and their use of 10
meter amplifiers, is the problem of interference generated by the amplifiers
due to
the lack RF chokes and filters for the simple reason that the unit is designed
for use on the 10, meter band, not the 11 meter band and thats what the chokes
and filters look for 10 meters, nothing more, nothing less!      Enter the
common travelling person with a late model vehicle. Most vehicles today have
some form of directed artifical intelliengence working under the hood. The
"brain" controls any number of common operations ranging from air / fuel
mixtures to how and when braking systems will perform. Microprocessors in
todays cars are as common as seatbelts and are now required to assist in
normal operations of said vehicles. And this is where the problem begins.
Since the
auto must have such control circuitry to function, then the possible
interference of such operations becomes a real threat. But what sort of threat
could be possible with a car, its control systems and a high powered
transmitting radio? Well, if one was to examine the idea of overriding or
shuting down said operations, the car would cease to function in any proper
manner. Such a shutdown could very easily cause fatal accidents and the cause
would be un-known due to all "looking" fine in any aftermath examination.  Now
we add to the scene, your common average trucker with such a radio in his
poccession and the ability to transmit high powered signals as one chosses.
One example of such high power hijinks would be the specfic targeting of autos
on
the highway with a points / scoring system based on performance, price, make
and if the car was built in the U.S. or not. What would be the outcome? To
answer,
it would be the shutdown of of the cars electronic logical systems causing
other systems on-board to do likewise in successive order. How can this come
about?  Well the answer is quite clear, the high powered signal causes the
logical centers to conflict or ignore basic operational commands from the
microprocessor in turn causing the microprocessor to close down, then cause a
halt to basic
actions and the car stops running.      Other known occuring incidents that
have had some humerous and fatal results have been reported in the past years
by the press. Examples are:

1. As early as the mid-seventies, Volkswagen developed a computer controlled
fuel injection valve control system. The car worked perfectly in Europe, but
had some unexplained engine failures in the United States. The problem of
engine failure was intermintent and very short lived when happening. The
alleged cause of such failures were the transmission of Citizens Band radio
frequencies from either mobile or base stations near by and causing an induced
current sufficent to cause a malfuncition.

2. It was reported that some GM cars were having problems with the use of two
meter radios and the electronic control systems. Other cars are reported to
have some problems with cellular phones. Reports from England even indicate
such problems occuring in a wide spectrum of autos in the area around Daventry
due to RFI from the transmitter used by Radio Four, a commerical station
transmitting
on 1500 meters along with local AM and FM broadcasts. It seems that the
station base was using a very high wattage transmitter and that when the
transmitter was transmitting, the cars that passed close to the station would
sometimes shutdown the engine causing minor overall problems and some angry
motorists. If you look at this problem, you may see possible small scale urban
electronic warfare possibilities. Two such areas might include the use of
directed radio energy against late model autos by law enforcement or worse, by
terroristic factions seeking to do the same thing. And one more example of
such reports concern the sudden acceleration problems with some imported cars
in the U.S. An interesting point to mention is that HONDA is offering owners
of the 1988 Civic a
replacement chip because of such reported problems.

3. On the lighter side of the problem, it was reported in the November 24th,
1987 edition of the Baltimore Sun, that some residents of Frederick, MD were
having problems with the use of their electronic garage door openers. Owners
of such devices returned them to places of purchase and found that the units
worked perfectly. It was noted that nearby, the U.S. Army operates a major
communications center for both domestic and international traffic. An Army
spokesman stated that they are not radiating anything that should lock up the
garage door recievers. It is also reported that when the Army turned off
certain transmitters, the garage door openers would work again. While the Army
stated that they were not the problem, the "problem" did disappear as stated
by the Army. You be the judge on this!

     On the fatal side of this problem, incidents were more deadly than funny.
Although the cause of such incidents was all not due to an "Alligator" radio,
but it was caused by the same type of over poowered raidiated radio
emmissions.  The cause was high wattage again and was to effect a new type of
utility helicopter in use by 2 different U.S. armed services. The helicopter,
known as the UH-60, Blackhawk or the naval version named Seahawk is
considered, operational state of the art in low level air combat situations
and is highly electronic in its basic make-up and operations. The problem was
two fold in
nature and both were to contribute in the final discovery.       The first
cause was due to the need of the design to employ a unique horizontal
stabilizer to help the helicopter improve it fly-ability. The stabilizer was
controlled
through a series of electronically activated hydraulic systems run through a
microprocessor that in turn was controlled from the cockpit through a series
of other logical and electronic relay systems. There was no physical
connection between the crafts flight controls and the pilot of the craft. What
is meant, is that the fly by wire method was replaced by a set of relays and
hydralic attenuators instead of cables and pulleys. It may not a been as
smooth as the electronic flight, but it took an explosive charge to bring the
control to a
dead stick and at the same time could be fixed with a pair of wire cutters and
clamps instead of a soldering iron and electronic parts.    The second cause,
being more unknown and deadly, consisted of radio frequency interferance
stemming from a number of different sources. One such source was found as a
common citizens band radio with major illegal power output. Another incident
of the same type of nature was discovered when one of the helicopters flew to
close to a commerical radio stations transmissions towers. Both times the
flight ended in fatalities for the crews. It was discovered that strong radio
was the cause.  According to published reports, 5 UH-60 Blackhawks have
nosedived into the
ground killing 22 serviceman since 1982. And the U.S. Army instructed it's
pilots that flights near microwave antennas or shipboard radar may cause
"uncommanded" altitude changes. In English, it translates to crashing into the
ground at a very high rate of speed!  0o, this basic simple problem was not
thought of as one that was possible even with the current concerns of systems
management in the now fully electronicisied battlefield.  So, the first
problem was that the controls of the craft are being directed by impulses
instead of physical controls. The second was the use of un-protected
electronics from both background and now, potential directed uses of radio
frequency energy as weapons
of warfare or even better, as stated before limited urban actions.    So now
we take the approach of normal radio environment and place an active thought
to possible options no available to a direct force. If reports of these
natures are known to the general public, then what is to stop the directed
force from becomming a new invisible tactic that can cause major disruptions
of
computer/communications systems currently in use.      Lets take the current
state of electronic protective measure in force and used by the different
defense agencies throughout the country. First off, we have the problem of
large Electro-Magnetic Pulses, (EMP's) being able to disrupt command and
communications links with the use of one nuclear device detoneated at a
unknown range above the continential united states.  Another example comes
from outside theoretical research concerning the SDI programs. One thought,
from Thedore B.  Taylor, a retired nuclear weapons designer and father of the
largest yield fission bomb, the S.O.B., was quoted in an interview published
in September, 1987. He stated that if you explode a one-kiloton device in
space and directed the energy into a 3 centimeter beam of radiation, you could
deposit enough
energy to wipe out electronic and electrical equipment - computers, antennas,
power lines, over an area larger that Washington, D.C. He was also quoted as
saying that microwave weapons are more than likely being developed too.    Now
weapons of this nature are on a very large scale and require vast amounts of
energy too start with. But in a directed small beam aimed at normal general
construction type buildings, a directed beam of energy cuts through walls,
doors, and windows as if they were not even there. Your example is some of the
local television or radio stations in your area. If you look at all or most of
the stations, you might find a small shack atop of their building. It may
contain the microwave dishes for the studio to transmitter links. The glass
and wood are nothing to the in-comming or out-going signals. Brick walls mean
nothing to a radio signal either. Just tune in your desk radio and listen to
your favorite station.  So this pulse would be able to short out almost all
commerical electrical, telecommunications, computer operations, and any other
devices that contain transistors or semiconductors for a circuit path. These
basic examples show what such types damage that these emmisionns may pose. The
second part of this problem is with the protection of such circutry. Great
amounts of technology protection comes in the form of deep trenches, standard
and special grounding of buildings and equipment, cable and support runways,
and concrete encasements. Now this is all wonderful and good from a military
viewpoint where money is no object, but in the real world, the use of such
protective measures is not possible even for the most prestigieous of
corporations.  Now if such large pulses can destroy equipment on a global
scale.  Then the idea of using such forces becomes a better local tool for the
destruction of security and measures taken to protect such devices and
facilities from a physical standpoint.  Ok now we know that the possibility of
directed energy may be used to disrupt the communications and operations of
logical devices. There are numerous ways to use such technology to gather and
alter electronic impulses. Another group of examples comes closer to the
common man and is happening all to frequently to the owner/operators of mass
communications systems. Best know, is the interruption of signals from a Home
Box Office satellite and the insertion of a message that stated its
subscripton rate was to high. That one incident struck fear in the hearts of
the communications industry and showed that anything was fair game.  Other
actions placed against commerical stations include the interception and signal
override of 2 television stations in the Chicago area. One such action was
placed against a Public Broadcasting station and the other was directed to one
of the "Super Stations" in the same area. The first pirate transmission lasted
15 seconds and the second, two hours later, lasted 90 seconds. The Pirate,
dressed in a Max Headroom facemask, uttered some statement, although garbled
and during the
second incident, bent over and exposed his / her rear and was struck on the
behind with a fly swatter to the shock of the viewers. Of course the FBI and
FCC were called in to investigate, but investigations of this sort led to
nothing
more than an empty trail.     Now to perform such deeds, one would have to
contact either the station or the local office of the FCC to find out what the
transmit and studio to transmitter frequencies are. (And this goes for any
transmitter registered with the FCC. They will supply the name and location,
frequency, and the maximum legal output of such sites.) There are two
frequencies used for each television channel. One for the Audio and the other
for the Video, or the other option, to listen or watch the station until it
sign's off for the day (night). This one method does not lead to possible
discovery and the frequencies are given at sign-on and sign-off. A good
example of such frequencies is with a station located in Philadelphia, Pa. The
station, WPVI, transmits its audio signal on commerical FM frequencies. The
frequency is 87.8 Mhz. Now anyone with a good transmitter could add anything
to the signal
and no one would be the wiser until they did.     Examples of such
transmitters and persons capable of doing this type of transmission is best
described by the incident in the summer of 1987 concerning Radio New York.
This radio station was considered a "pirate" station and the federal goverment
decided to move in and shut them down. An interesting note to all of this, was
that the station was located on a ship anchored off the coast of New York
outside US boundarys. Still the US goverment with agents of the FBI, FCC,
Customs and the Coast Guard
boarded the vessel, closed down the station, arrested the persons on-board and
the ship was taken in tow. End of that particular story.    On the other hand,
two other stories of interest deal with the possible and real way some may be
able to jam or possibly damage state of the art satellite communications. The
first dealt with a group who call themselves the American Technocratic
Association based in Wilmington, Delaware. This groups thought revolve around
the scrambeling issue in use by the pay TV companies. The background of the
members of this group claim to have a good working knowwledge of military
radar communications systems. The group claims to have the capability to jam a
satellite with a few mobile systems it has. One operation that the group hopes
to undertake was called "Operation Sunspot". The group claims to have areas
mapped out that have no treaty, regulation or statute dealing with the jamming
of a geo-stationary satellite. The one problem with all of this is that such a
thing could happen very easily. Now there are some who say that such things
could not happen, but if one is to look in a number of magazines for such
information on frequencies or locations, you could find it.      So you say to
yourself that you want to try this experiment. Well we will not supply exact
details of such techniques, but will say that HAM radio operators have the
ability to contact both American and Soviet repeater satellites and if you
wanted to you could do the same thing. Now for such systems, you would need a
transmit dish and the power behind the signal. So for a ten foot dish, you
would need 91 watts, a six foot dish, 280 watts. It may not be dirt cheap to
generate high powered signals in the mid range of 1-10 Ghz, but it does not
present a great techincal obstacle and surplus gear is so easy to obtain.  You
don't need large dishes with great amounts of power to do this.  All that is
needed is a moderate size dish, a few tens of watts at microwave frequencies,
and Bingo!
You've got an effective satellite jamming station!   And then you have to
address the issue of the telemetry channel. They may not be able to overtake
the signal, but if jam the signal with another, it may be possible to affect
the operation, stability or orbit of the target. Frequency crystals for such
channels are available from a number of sources and for as little as $2.50 per
frequency, and are used in inexpensive surplus equipment.   Now these examples
and the reported stories dealing with television stations interuption's are
fast becomming one of the most feared aspect of open air transmissions. Such
transmitter frequencies are no longer the domain of commerical radio and
television stations. Transmissions on any frequency are just a phone call away
from suppliers who provide common or business radio transmission technology.
     So if satellite and television stations can be interupted by such forces,
six million dollar helicopters are taken down because of CB radios, and
automobiles cease to operate due to a wide spectrum of emmited signals, then
the possibility to intercept and harvest vast amounts of knowledge is
available to
those who wish to gather such.     Now to explain such basic interceptions are
now commonplace with horrific results to those who do not believe that such
things can happen. For a simplistic view of such emmited signals, take a
standard "Walkman" type of radio and visit one of the many locations of ATM's
or better known as "money machines". (This excerise may also be performed near
any standard personal computer if such machines are not available.) and tune
through the FM band. With careful tuning, one will be able to "hear" machine
funcitions occuring. Taking basic simple electronics, one may have the ability
to recieve
and reconstruct such impulses to a readable form.      Or an example of larger
scale and better know, would be with the use of back-yard home satellite
dishes.  Dishes range from 6 to 12 feet wide. Signals available include music,
sports, news, movies, stock and commodity trading quotes, weather, education
and other such information services. In addition to these services, a number
of different multi-site conference services are available from a host of major
hotel chains
as well as privatly organized meetings held for specfic time periods and
dates.  All may be tuned through the use of a dish and sensitive information
that may
not be available to someone, is then made available and no one is the wiser!
Transponders are not private, and are rented out for only the time used. And
one other thing that might bring you to your senses about such signals, is
that the signals are transmitted by the satellite over a wide area to anyone
who can
recieve such signals.    One other development is the small Micro-Sat by
Norsat.  This complete system offers both satellite bands coverage, Ku and C,
a small
dish and circuit board that fits inside an IBM PC. The unit downblocks 950 Mhz
to 1.45 Ghz, offers a maximum baud rate of 9600 bps, frequency, bandwidth,
video and audio selectable formats and may be connected to the VideoCipher II,
B-Mac
and Oak Orion descrambling systems.     Some other such signal reconstruction
devices are now also available through the mails. One such device is available
in plan form from Don Britton Enterprises and is called the Re-Process Sync
Amplifier. The device was developed to recieve signals emmanated from cable
television systems. What the device does in essance, is to take a signal that
"leaks" from cable tv systems and recieves such, adds a sync signal needed by
the television set to display the recieved signals and then sends the signal
to the antenna input of the set so that display may happen. Now if weak signal
reception is available from leaking cable systems, then the ability to recieve
weak signals from logical devices is also possible.

Interception and Weapons Possibilities
--------------------------------------

     Think about possible interception points pertaining to logical security
methods. Communications may be encrypted, data may be stored in an in-active
form and access is only a matter of time while the interceptee is waiting for
the dispersal. The next security concerned area covered would be for the
encryption of the information in its stored and transmitted form. The
encryption is all wonderful and good for the transmission and storage, but
does nothing for the information as it is in its final stage to the human
eyes! And you only have
two ways to get it to the eyes, in hard copy or by a video screen.    Now you
think that interception is not possible since the information is encrypted,
but the data must be decrypted so that the human connection may use the
information.  The human connection allows for the reception of said
information by the afore mentioned devices and lets interception to happen
through the clear or
decryption points of the attacked devices.  And one other point to mention;
other possible effects of reception/transmission to security in general, could
affect other controls ranging from building energy management to security
access
and monitoring controls.      To give a better understanding of such
equipment, we will discuss some of the devices known. One such device known as
the Van Eck device and the other is called the Re-Process Sync Amplifier. Some
may feel that there are two different systems involved in this discussion, but
the author
finds no major difference between the two, with the exception of the Van Eck
device is built for operation on European voltages and has a built-in digital
frequency meter. The one major difference found is with the dates of
copyrights for the two devices. The Don Britton device is dated 1979, while
the Van Eck
unit is dated October,1985.

Note: Another unit, with plans for such devices, are available from
Consumertronics, located in Alamorgordo, New Mexico. Besides the plans for a
Van Eck type reader, one book offers information in reference to computer
crime and countermeasures, how systems are penetrated, BBS advice, Password
defeats, TEMPEST, crosstalk amplifiers and a 200 word phreaking terms
glossary. All for only $15.00.

     We will begin with a basic understanding of the inner workings of the
device. The one other major basic difference with the two reader boxes is that
the Van Eck box is designed for use with tv's and VDT's used in Europe as
compared with the Britton box built for use in the United States. This device
in general, is designed to restore and regenerate the sync and colorburst
signals and ignores all information appearing during either the vertical or
horizontal blanking. Its basic result is reconfigure through the use of
supplying artifical external signals inputed directly to any video monitor
through a simple 10-50 dollar modification of the TV or video monitor, or in
simple english, takes a weak video signal and tries to shape or match it and
then boost its output to a
normal television screen.     One other interesting thought comes to mind with
the use of video tape copy protection methods. Since these methods use a means
that makes it tough on the VCR not the TV from generating signals for tape
duplication, there have been a number of devices that assist in the retoring
and re-structure of the picture and sound. One device is known as the "Line
Zapper".  The device helps to adjust the brightness changes, vertical jumping
and jittering, and video noise. It is available in kit or complete form.
Pricing starts at $69.95 and complete tested units cost $124.95. Now if this
unit can assist in the filtering and structuring of commerically induced weak
signals, then it should be able to take a boosted signal presented to it and
clean the picture to something of useable form. Some may see this only as a
filter for video processing with a focal point on the actual copy-guard
techniques, but
such a device incorporated into the Van Eck type of gear should assist in the
overall signal restructuring.      Now one other interesting point about
possible video signaling re-construction methods was addressed in a multi-part
series published in Radio-Electronics based on the methodology used for the
construction of video signals scrambeled by different vendors of cable and
over-the air pay television. The series dealt with all aspects and methods of
video and audio, (complete with discussions on the DES methods used for the
VideoCipher units and the like,) used in commerical systems in use.   One
other thought comes to mind of an experimental nature. Since the screen of a
computer is not always changing and for the most part stable in its display,
why not take the recieved signal and digitize it! You could filter out signal
noise clean up any true video signal present. This is no great techno-wonder,
the basic gear could be put together with Radio Shack or the like types of
equipment. And the cost is still most reasonable. If not available there,
costs for home-brew gear would not be that high. The simple electronics blocks
would consist of comparators, video detectors, data seperator gates, a to d -
d to a converters, data amp and a signal level converter, or the better
version, might be a
modified slow scan television system with error correction and clean-up
circuits. Such units work over normal phone lines or standard radio channels
and since the units can take signals from these two different types of inputs,
there should be no problem in adapting the unit to accept a cleaned up analog
signal
from a digitizer.   Away from the world of the experimental thoughts, we
return
to the point at hand....      Now there are two types of monitors used today.
The first, called composite and the second using TTL logic to control the
screen and its pattern. The composite screen is nothing more than a television
set or Apple computer type of monitor. The construction of the picture is
performed by
a beam of electrons that are scanned across the screen at a rate of 525 lines
per second. Since the majority of screens are of a composite nature ( this is
even true in most IBM environments) the ability to recieve the signal is very
possible from a radio emmission standpoint.  The reception of such signals is
not fairytales, but comes with reality attached through the use of simple
electronics. The first part of the reception project is to have a method of
signal acaquisition and amplifcation. Such gathering may be performed by the
use of standard electronics store technology. For this example, we will use
common Radio Shack electronics. The reason is due too the common variety
electronics that are available to most persons needing such science to
accomplish the
required gathering.      To start, since a base station is out of the question
due to the weak signals one would have to recieve. So the need for
transportable equipment is a must. Antenna, amplifier, sync process unit and
display medium must be powered in the transit unit. Depending on budget and
(BEL) (Basic Equipment List) requierments a fully battery operated set-up can
be
constructured for under ................     Our two systems described here
will be different only in basic construction and budgetary BEL's.

The "Radio Shack" Reader
------------------------

1. The antenna could consist of a Radio Shack TV/FM # 15-1611 for 49.95

2. If needed, Radio Shack in-line signal amplifier 10 db gain # 15-1117 for
15.95

3. Radio Shack RF Video Modulator # 15-1273 for 26.95

4. The Britton or Van Eck unit (Cost unknown due to construction needs)

5. The tuning unit may consist different available FM,TV,UHF tuners available
for the tuning of TV Sound & Picture reception and possible recording. Costs
for such units range from 319.95 to 119.95  The 319.95 unit can operate on AC
/ DC, has audio / video input jacks and can operate on 9 "D" batteries. Other
possible useable units would  be either # 16-109 or 16-111. The units cost
219.95 and the other 159.95.  Both are able to tune in the full commerical AM
/ FM and VHF/UHF Television signals, The low end of the cost spectrum would be
the RS # 16-113 at 119.95 This unit also has the same spectrum tuning
abilities.

The Gold Plated Unit
--------------------

1. The antenna could consist of a Radio Shack TV/FM # 15-1611 for 49.95  (Or
due to the use of better reception electronics having built in antennas. But
due to the need for amplified signals being inputed to the reciever we will
still
possibly use the RS amplified antennas.)     a. It is also possible to use any
number of amateur radio antennas for the purpose of maintaining a low profile,
we will use one of the standard active recieving antennas that has a spectrum
of reception from 50Mhz to 1 Ghz. Such units are available from mail order
supply houses.

2. If still needed, Radio Shack in-line signal amplifier 10 db gain # 15-1117
for 15.95 It is also possible to use # 15-1105 Indoor FM Signal Booster with
switchable 0,10 or 20 Db gain at a cost of 24.95.

3. Radio Shack RF Video Modulator # 15-1273 for 26.95

4. The Britton or Van Eck unit (Cost unknown due to construction needs)

5. Tuning units- The tuning units would consist of 2 seperate radio units. The
units, both ICOM's have a combined tuning range of 100 Khz to 2 Ghz.  a. Unit
1 (R-71a) tunes from 100 Khz to 30 Mhz. This unit is nothing more than a
shortwave reciever with excellent signal reception and frequency stability
that offers far better overall signal interception quality.  The unit offers 1
Hz tuning and has
digital frequency readout.   As an option, this unit may be controlled by an
IBM
or compatable PC.  Cost for this unit is $949.00.      b. Unit 2 (R7000)
covers 30 Mhz to 2 Ghz. This unit is a general coverage  reciever with
excellent signal reception and frequency stability that  offers far better
overall signal tuning and interception quality.  Also this unit can be
computer controlled through an IBM or  compatiable. The unit offers .01 Hz
tuning and has digital frequency readout. Additional abilities of the unit
include signal output and an IF output of 10.7 Mhz with other frequencies
available. The cost for the unit is $1099.99.  This particular unit also has
an option for the  output of the video signal and connection of any standard
video monitor for 130 dollars. For an additional 160 dollars the unit can have
the ability to recieve signals from 20 Khz and go all the way to the specified
2 Ghz. The unit needed is called a Kuranishi FC-7000 frequency converter. With
additional commerical television MDS tuning equipment, ranges can exceed 2.7
Ghz. Costs for this will range between 79 and 109 dollars.  Since we will be
mostly dealing in the lower ranges of frequencies, an added piece of gear may
be used to gain the best signal reception points available.  This is through
the use a Radio Direction Finder available from American Electronics for 100
dollars.

     Now with all this equipment for both systems, another basic system with
minumum cost is readilly available to many for under 100.00 dollars. This we
speak, of is the common Black & White Television set available in mass
quanties from any number of sources. It has been reported that such
interception capabilities are possible and have occured without the
interceptee knowing until the CommunicationsCommission have contacted the
source of the emmited signals.  For example, some personal computers and their
respective screen have been known to been picked up on the TV screens of their
neighbors and through nothing more than rough or fine tuning the reception.
The reason is due to the TV having the ability to automatically adjust the
Sync signals to those close to the frequency of intercepted computer screens
sync frequency. This "ability" is available through the use of a common manual
type tuner on a standard Black & White set with a normal directional antenna
and an standard antenna amplifier.  All three devices in common life and
attached to your own television recievers!  You have such devices if you have
an antenna on your roof or attached to your set. Most have attached signal
amplification due to the ever growing background noise generated by normal
commerical stations and reception charictersistic In simple term, the guy next
door can read  your screen and you don't know it. Now take the number of
personal type computers in a standard corporate environment, caulculate the
possible dollar figures of the combined information contained in these
machines, and substantial sums become more evident than ever before. If
business plans, formulas or patent-trade information, client lists, or any
other type of valuable information and since that information will be called
up at any time or current work performed is wanted in the surveillance
gathering operation and then you have a completely wide open way of monitoring
the daily practices and transactional actions with complete impunity and
securty of such areas is
completely unguarded due to the lack of knowledge.     For experimental
purposes, we will use very simplistic computer systems to give an idea of what
may be possible. The equipment shall be basic, over the counter, cheap,
electronic systems to gather and produce the signals we which to collect.

The equipment list is as follows:

1. Franklin Ace 1200 (Apple II compatiable)

     a. Franklin Ace Serial / Paralell Card
      (Paralell card is in use for the 2 printers.)
     b. Apple Super Serial Card (RS-232) for use with the communications
        modem.

2. Franklin Video Monitor (40 or 80 characters display)  18 Khz.  ( Standard
IBM monitors sync at 15 to 16 Khz.)

3. Prometheus ProModem 1200 (External type)

4. Printers
     a. Okidata Microline 92
     b. Epson MX-80

Our basic reception / interception equipment consists of:

1. Bearcat 250 (50 Channel) Scanner (Coverage from 32-50,146-148,148-174,420-
450,450-470,470-512 Mhz)

2. Soundesign FM Stereo Tuner (86.5 Mhz to 109.5 Mhz)

3. Electrobrand AM-FM-SW-CB-TV-PB-AIR-Weather.  The AM and FM are standard
commerical band recievers.  SW is short-wave from 4 Mhz to 12 Mhz.  TV
coverage is from audio channels 2 through 13.  AIR band from 108 through 135
Mhz.  Public Band is 145 through 175 Mhz.

4. A Gould OS 1100 A Osocilliscope 25 Mhz range

     Since we will not try to re-construct the actual video signal generated,
as this has already been done, we will not have to explain what we recieve as
a picture. What we will cover is the gross signal output of standard
population computerized logical systems. In our observations, we have seen a
wide spectrum of emmitted signals with a strong signal between 9.0 and 9.250
Mhz for the display of standard text scrolling by. Better signal display was
found at the lower frequencies of 9 Mhz. Monitor frequencies were found in the
area of 11 through 19.5 - 20 Mhz. Printer frequencies are in the range of 140
to 200 Mhz.  Disk operations were detected in the ranges of 88 to 250 Mhz.
Overall frequency generation was from 4 through 500 Mhz. The modem was found
between 28 and 300 Mhz. All in all, this easy discovery of radiated or
transmitted signals by means
of common radio technology could lead to.    An interesting thought comes up
with the use of some common ham transcievers for such operations, and with
simple, easy modifications, some can transmit on all frequencies from 1.6 t 30
Mhz. Such a transmitter would be the Kenwood 440. This transciever offers 100
watt output and as stated all frequency transmit. To perform the small
modification, all one would have to do is cut one lead to a diode (Diode D 80)
and as an added bonus for better frequency  readout, you gain an additional
readout of  10 Hz by snipping the lead to Diode 66. So the unit covers the
range of IBM PC frequencys in use and all of the Apple systems too. Thats says
it all!  It can offer the possibility for disruption of internal signals used
to process information and the possibility of causing other logic related
systems to act or
not without reason.      For example, would it be possible for the Soviets to
sit under cover with a modified Kenwood 440 100 watt radio or better yet, a
Radio Shack 40 channel AM / SSB and a 100 watt Firebird linear amplifier and a
simple small antenna to disperse the signal. So the problem of the 6 million
dollar helicopter comes down to a wholesale cost of 150.00 ( 190.00 to 200.00
for an average rip-stop nylon camping backpack unit ) per man with a
recommended dispersal of 3 manpacks per unit into the theater. Suspected
effective ranging
up to 3 miles per man pack unit is suggested, or even better, if such things
were possible against military aircraft or normal commerical real world autos,
then directed intent should be of now problem against civilian targets such as
computer installations, bank and operations support structures, possible
override of security systems and any other systems that may be affected by
such
forces.   Other uses of directed energy may be used in law enforcement
situations for the apperhension of suspected persons in late model
automobiles.  If the truckers are using the radios for game playing, then why
can't the police
have the same type of device for the stopping of autos?     On the other hand,
there is a device known as a Radar Speed Gun Calibrator (or better know as a
radar jammer) for use with calibration of speed guns or for the deceiving of
police radar units. The plans for such units were (are) available for a number
of sources. One such source, is Philips Instrument Company or another such
source was the Radio-Electronics issue in the  spring or summer of 1987 with
plans for the Radar Speed Gun Calibrator, that would allow you to transmit a
signal that would equal the same type of reflected signal from an automobile
traveling at the supposed testing speed. Range's of speed signal output would
equal 5 mph to well over 100 mph.  Some plans or kits come with instructions
for the combination of radar jammer units with most commonly available auto
radar detector units. In simple terms, the radar detector unit detects a
signal and through its display or attention getting circuitry in turn
activates the radar jamming equipment to deceive or jam the police transmitter
/ reciever units.  Best know of such combinations, were the use of Escort
radar detectors and
jammer units with transmission horns mounted behind the front grill of autos.
No
ifs, ands, or buts, they work!     One other piece of equipment that may have
devastating effects on overall security and support systems, deals with the
generation of very high energy pulses that might be classified as being able
to generate EMP's that could damage almost any piece of electronic gear. The
claim from the designer is that this device can generate a pulse with an
effective power of multi-millions of watts. The device on average will produce
a pulse equal to 400,00 wats in a testing mode with the multi-million outputs
available with full charging of the capacitor banks peaked. Also stated in
this book is
the ability of the unit to produce a very large inductance in near by
electronic gear. Most interesting! And the only statement in this book about
the device and it's short comming, has to deal with the in-ability of the
device to produce sufficent output used in certain nuclear experiments. I
wonder what that means?  So, in closing, the capability of these units is well
within the range of any person with the intent comes closer to home than ever
before. The equipment is nothing of major technical wonderment, just a few
simple block circuits put together to each other so that they work together to
do the final requested product. And all of the described gear or plans may be
in the hands of everyday persons even if they don't know it! And while most do
not have such knowledge about how such systems may be used to corrupt other
systems, or even how the average telephone or toaster may work, they will
still state that such described technology is not possible, and open the door
to major disaster due to complete ignorance to the problem. In closing, to
steal a phrase from someone else, "The truth shall set you free (or may keep
you from being over exposed from free form energy)!

"Click!"  And the last words spoken by the corporate DP offical were...

" Thats impossible! You could never do that to my operation!"
