...or, why we listen to the wires.
Electronic surveillance devices (audio, video, data) are often referred to by their generic term — bugs.
Bugs may be highly specialized, as in a video only spy camera, or may incorporate audio, video and data snooping. An example of this is a
device which is secreted in a vehicle, which collects GPS data, audio and video.
Most people, however, think of bugs as audio-only radio transmitters.
Often the simplest bugs are the most effective. These are just microphones attached to a length of wire.
The other end of the wire can be connected to a distant radio transmitter, voice recorder, or simply an amplifier with headphones.
Most people are surprised to learn all homes and offices come prewired, bugging-ready.
Standard telephone cables have unused pairs, and computer Ethernet cables generally only use two of the four pairs they contain. Most older office buildings also have legacy wiring which was never removed.
These "hardwired" bugs are among the most difficult to detect, which is why spies and law enforcement favor them.
Since a microphone is the main element of a hardwired bug,
I thought it might be very useful to show you how small they
can be.
These fingers are holding a real microphone, actual size.
Now you know just how much the other picture was enlarged.
Amazingly small, these microphones are mass produced by the millions.
Fortunately, most wind up in cell phones and hearing aids. However, many are sold on eBay for pennies, and then become bugs.
Not everyone knows how to find these. But, don't worry,
we do.
gives the government what critics claim will be some of the most intrusive spying powers in the “history of Western democracy.”
More than a decade before Edward Snowden famously leaked thousands of classified records to the world, another U.S. government contractor tried a similar move the old-fashioned way. His name is Brian Regan. And in 1999 and 2000, he smuggled classified documents out of his office and buried them in the woods hoping to sell them to a foreign government. But he was foiled in part by his own terrible spelling. 
Adups has over 700 million active users, and a market share exceeding 70% across 200+ countries and regions. 
Many mom-and-pop retail stores maintain websites for selling their wares, and some entrepreneurs create online-only stores that ship products directly from warehouses. Unfortunately, scammers also use ecommerce as an opportunity to take shoppers' personal and financial information from afar. An odd-looking site or too-good-to-be-true deal might be the work of scammer rather than an ecommerce amateur. The following 10 signs can help shoppers distinguish between the two. more
The committee disapproved of this spy method in an opinion issued in late October, saying that it violated the Last Frontier’s version of Model Rule 8.4, which prohibits dishonesty and misrepresentation.
Take for example, the case from October 2016, when a Chinese man was sent to prison for 3 years... The crime was part of a years-long conspiracy involving several Chinese citizens aimed at stealing valuable patented corn seeds from Iowa farm fields so they could be smuggled to a Chinese agriculture conglomerate.”...
accused of creeping around an apartment complex and spying on people. The suspect is a funeral director and embalmer.
The ultrasound, which contains frequencies far outside our range of hearing, is completely inaudible. But as the ultrasonic beam travels through the air, the inherent properties of the air cause the ultrasound to change shape in a predictable way. This gives rise to frequency components in the audible band, which can be accurately predicted, and therefore precisely controlled. By generating the correct ultrasonic signal, we can create, within the air itself, any sound desired.
