Get an SDR, tune into the frequency, and troll the home automation system! Given that it’s not of a high frequency, the attack can be done from a distance with proper antenna, and the frequencies use a hardcoded algorithm. Hell, I wouldn’t be surprised to see flipper zero addon to that (hardware through GPIO and software) for portability.

- tamimio 6mo agoYes it does, my LimeSDR can go to 100khz. If you need less, just get a piezoelectric transducer paired with signal generator like arduino or esp32, might add drive circuit/gate driver to improve it. It’s very doable, and you can programmatically troll the system knowing the algo, and I am saying “troll” but obviously you can have serious use of that.
