This 2.4 GHz bug is just one of many eavesdropping devices, GPS trackers and spy cameras flooding the market these days. Corporations valuing information security and privacy need to be especially alert.
These surveillance devices are not sophisticated, but they are very effective. Worse, they are readily available to anyone with a credit card and internet access. Most are so inexpensive they are considered “toss-away” — use once, don’t retrieve — perfect for short-term, low-risk use.
Let’s examine the 2.4 GHz bug ad…
It comes semi-assembled. Total cost for one transmitter, one receiver, plus shipping: $9.33. Just add batteries and an audio amplifier on the receiving side; you now have a spread-spectrum, encrypted, Wi-Fi bug. Here is how the seller describes their product…
A few years ago this would have been considered science fiction, or a very expensive government spy gadget. Today, it is the price of a Venti Latte and a breakfast sandwich.
2.4 GHz bugs are very small. They can be hidden, or built into, anything. The power supply or battery will be the biggest component. Consider one built into a USB charger. No-one would suspect it.
Building a Test Bug…
In our test, we didn’t try to be covert. We just slapped it on the back of a AAA battery pack. Still, it was very small and could be easily hidden.

Pretty simple.
Test Results: When activated the transmitter and receiver create their encrypted link automatically. Reception distance was as advertised. Adding a high-gain 2.4 GHz directional antenna on the receive end could boost this receive distance 3 to 4 times, thus making the bug an even more potent eavesdropping device. The most surprising results involved clarity and sensitivity. Audio was crystal-clear, and any whispers in the area were picked up with ease.
TSCM Detection of the 2.4 GHz Bug…
Detecting this bug was not easy. Several professional Technical Surveillance Countermeasures (TSCM) detection techniques were attempted. Only one succeeded reliably.
As a side note, if you are concerned about this type of attack you will need the help of a TSCM specialist to discover it. None of the cheap bug detection gadgets will find this bug.
When transmitting, a distinctive spread-spectrum waveform can be seen using a Spectrum Analyzer, as seen in the video below. When the 2.4 GHz bug is active it leaves a red, Bart Simpson haircut shape on the screen. When the bug is turned off, Wi-Fi and Bluetooth signals—previously obscured by the bug transmission—can be seen.
