eldraco/salamandraSalamandra is a tool to find spy microphones that use radio freq to transmit. It uses SDR.
Salamandra is a tool to detect and locate spy microphones in closed environments. It find microphones based on the strength of the signal sent by the microphone and the amount of noise and overlapped frequencies. Based on the generated noise it can estimate how close or far away you are from the microphone.
To use Salamandra you nee to have a SDR (Software Define Radio) device. It can be any from the cheap USB devices, such as this.
Salamandra needs the rtl_power software installed in your computer. To install it you can do:
On MacOS:
sudo port install rtl-sdr
If you don't have ports in your MAC, see port installation
On Linux:
apt-get install rtl-sdr
On Windows: See http://www.rtl-sdr.com/getting-the-rtl-sdr-to-work-on-windows-10/
If rtl_power was installed correctly, you should be able to run this command in any console:
rtl_test
And you should see one device detected.
./salamandra.py
This command will use a default threshold of 10.8, a min freq of 100Mhz, a max freq of 400Mhz and sound. You can change the default values with parameters.
Run Salamandra with a threshold of 0, starting in the frequency 100MHz and ending in the frequency 200MHz. Search is activated with (-s). And make sounds (-S)
./salamandra.py -t 0 -a 100 -b 200 -s -S
./salamandra.py -t 0 -a 111 -b 113 -s -f stored.csv
To actually create the file with rtl_power, from 111MHz to 114MHz, with 4000Khz step, gain of 25, integration of 1s and capturing for 5min, you can do:
rtl_power -f 111M:114M:4000Khz -g 25 -i 1 -e 300 stored.csv
Run Salamandra with a threshold of 0, starting in the frequency 100MHz and ending in the frequency 200MHz. Search is activated with (-s). And make sounds (-S)
./salamandra.py -t 10.3 -a 100 -b 200 -F 2
