Salamandra is a great tool for detecting and locating spy microphones in different environments.
This awesome tool can find microphones based on the strength of the signal sent by the microphone and the amount of noise and overlapped frequencies.
With the big boom of Internet of Things (IoT) devices, and some hardware now being banned due to spying concerns, it would be nice if there was an easy way to scan your office or home to see if there are any hidden microphone “spy” devices.
