-
- In today's landscape of insider trading, leveraged buyouts and merger mania,
- it is no great shock that a new underground industry has developed within
- telecom -- eavesdropping.
-
- Bugs are cheap (starting at $30) and can be installed in as little as 10
- seconds. And you can bet your bottom $1 million that this expense pales in
- comparison to the rewards of finding out your takeover plans, marketing
- strategies, and product developments.
-
- According to Fritz Lang of Tactical Research Devices (Brewster, NY), there is a
- virtual epidemic of bugging going on in the American marketplace. Counter-
- surveillance agencies like TRD have sprung up all over. They search for
- eavesdropping equipment, then notify the client if they're being tapped. It's
- up to the client to respond to the intrusion.
-
- Each of TRD's employees is a retired CIA or FBI operative. Formerly, they
- planted bugs for Uncle Sam. Since it's illegal to plant bugs for anyone else,
- these men now engage in counter surveillance work, pinpointing eavesdropping
- devices, and sometimes the culprits who put them there, for TRD's client
- companies.
-
-
- Where Do They Put The Bugs?
- ~~~~~~~~~~~~~~~~~~~~~~~~~~
- Your TELEPHONE, of course, is a convenient place to install an eavesdropping
- device. But this doesn't mean that the illegal tapping will be limited to your
- phone conversations.
-
- Electronic phones have microphones which are always "live," even when the
- telephone is on-hook. Stick an amplifier and transmitting unit to the
- microphone, and you have constant surveillance of all conversations taking
- place in that room, whether or not the phone is off-hook at the time.
-
- A device rapidly gaining popularity among today's wire-tappers is a mouthpiece
- containing a tiny bug, which looks exactly like the one of your 2500 set. All
- it takes is one trip to the water cooler or the men's room for the insider to
- surreptitiously make the old switcheroo.
-
- LOUDSPEAKERS are another favorite location for wire-tappers, because they can
- pick up conversations when not in use. Paging systems, piped in music, and
- telephone systems all employ some variety of amplifier which the culprit can
- use to his advantage.
-
- LINE INTERCEPTORS allow eavesdroppers more extensive coverage of your
- activities, since they can monitor more than on-line communications from a
- single listening post.
-
- But really, the number of places you can find a bug is limited only by the
- tapper's imagination. Light switches, plugs, clocks, calculators, legs of
- wooden chairs, staplers, ashtrays, the underside of a toilet bowl -- all of
- these items have proved fertile territory for the little critters.
-
-
- Tools For Finding The Bugs
- ~~~~~~~~~~~~~~~~~~~~~~~~~
- TRD's people use a patented Surveillance Search Receiver to locate the bugs.
- The Receiver uses a broad-band radio spectrum, from 25 kHz to 7 gHz.
-
- If there is an unaccounted-for radio frequency emission on the premises, the
- Receiver will tune it in on a small spectrum monitor. It then traces the
- emission to its inevitable source, the bug.
-
- For room bugs, they also use a Non-Linear Junction Detector, which can pinpoint
- all electronic circuit diodes or resistors in the architecture of the building.
-
- The Detector emits a high microwave signal into walls, furniture, et al.,
- causing any circuit hidden within to oscillate. As soon as they oscillate,
- they become detectable.
-
- Mr. Lang clears up a misconception about the Russians bugging our embassy in
- Moscow. "They didn't riddle the building with actual bugs, instead, they
- buried millions of little resistors in the concrete."
-
- The embassy, therefore, became a hot bed for false alarms. Whenever the
- American counter-measure people came in with their detectors to look for a bug,
- they'd pick up oscillation readings from the countless resistors and
- capacitors buried in the walls. Finding any real bugs would be infinitely more
- difficult than finding the old needle in a haystack.
-
- For finding wire-taps along the phone lines, TRD uses a computerized electronic
- Telephone Analyzer. The unit runs 18 different tests on phone lines between
- the CPE block and the Central Office (CO). Resistance, voltage, and line
- balance are just a few of them. Once they locate a tapped line, they send a
- pulse down it with a time-domain reflectometer, which can pinpoint exactly
- where in the line the bug has been affixed.
-
- Bear in mind that wire-tapping is extremely difficult and time consuming. As
- much as 20 hours of conversations has to be monitored every single business
- day. Because of this, key executives' telephones are usually the only ones
- slated for a wire-tap.
-
-
- Catching The Culprit
- ~~~~~~~~~~~~~~~~~~~
- Finding a wire-tap is easier than finding the spy who bugged your office.
- Direct hardwir taps can be traced to the remote location where the snoop
- stores his voltage-activated electronic tape recorder. After you've found the
- monitoring post, it's a matter of hanging around the premises until someone
- comes to collect the old tapes and put in fresh ones.
-
- As for room bugs, your best bet is to make the device inoperable, without
- removing it, and wait for the eavesdropping to come back to fix or replace it.
-
-
- Once Is Never Enough
- ~~~~~~~~~~~~~~~~~~~
- Some of TRD's clients have their offices checked monthly, some quarterly.
- After the initial sweep, you can have equipment installed on your phone lines
- which constantly monitors any funny stuff.
-
- As for TRD, they offer a money-back guarantee if they fail to detect an
- existing bug on your premises. Mr. Lang assures us that Fortune 500 company
- has been bugged to a greater or lesser extent. That's how out-of-hand the
- problem is getting.
-
- Toward the end of our conversation, Mr. Lang pauses. "So you're really going
- to print this, huh? You're really on the up and up?" Then he spills the
- beans.
-
- It turns out Mr. Fritz Lang is really Mr. Frank Jones (he says), a licensed
- private investigator with a broad reputation in the industry. He used the
- alias because he suspected I was from a rival counter-measure agency, or worse,
- a wire-tapper, trying to infiltrate his operations.
-
- Which quite possibly I am. You can't trust anybody in this spy business.
