Then when compiling I was seeing a lot of CC command unknown errors. To fix that I just added CC=gcc to the top of all makefiles.

You need to install MingW32 and MSYS and put their bin folders in your Windows PATH.ģ. The 64-bit version won't work with extio's possibly because they are all 32-bit. Also install the JDK.Ģ. You need to install a 32-bit version of the Java runtime.

In his email flatflyfish showed us how to compile a new version that does work.ġ. TempestSDR showing what's on the screen via unintentional RF radiation from the monitor.Īlthough TempestSDR has been released now for a number of years it hasn't worked properly in Windows with ExtIO interfaces. This can let you view what is on a screen without any physical connections. If a high gain directional antenna is used then it may be possible to receive images from several meters away as well. TempestSDR is an open source tool that allows you to use any SDR that has a supporting ExtIO (such as RTL-SDR, Airspy, SDRplay, HackRF) to receive the unintentional signal radiation from a screen, and turn that signal back into a live image. For example the unintentional signals from a computer screen could be captured, and converted back into a live image of what the screen is displaying. All electronics emit some sort of unintentional RF signals, and by capturing and processing those signals some data can be recovered. If you didn't already know by definition 'TEMPEST' refers to techniques used by some spy agencies to eavesdrop on electronic equipment via their unintentional radio emissions (as well as via sounds and vibrations). Thanks to reader 'flatflyfish' for submitting information on how to get Martin Marinov's TempestSDR up and running on a Windows system.
