This allows you to read key fobs like modern wireless car key fobs, garage door openers, ceiling fan remotes and many other devices that use sub-GHz frequencies. My first attempt to clone my wireless car key fob and garage door failed. This will only work with some kinds of wireless, usually older doorbells-Ring or Nest doorbells are probably safe-and you need to first read the doorbell to get the right frequency, but if you do that, you can play ding-dong-ditch from a distance. This blog post will focus on Sub-GHz and one potential abuse of capturing Sub-GHz signals. In this blog post, I am going to be exploring one potential physical security attack chain, relaying a captured signal to open a gate using a device called the Flipper Zero. Perhaps the most surprising thing when I started playing with my Flipper Zero was how far it could transmit. While I acknowledge that modified versions of Flipper firmware exist with additional functionality and less restrictions, for the sake of simplicity and to better demonstrate the low barrier to entry for a potential attacker, a standard Flipper Zero was used for this experiment. The Flipper Zero was mounted on an all dielectric (plastic) 2-axis positioner and moved through hundreds of orientations while the far field radiated signal level was measured.
