Cranes, trains, building controls, oil rigs, and …ceiling fans? Recent developments have made secure wireless protocols more common, but the fact is there's still a swarm of simpler RF controls in the wireless world around us. Luckily, the onset of Software Defined Radios (SDRs) means analyzing these insecure signals is easier than ever! We'll explore the basics of capturing and reversing simple RF control signals with the affordable RTL-SDR. With a little exploration through this menagerie of signals, we can unravel the mysteries of their operation and better understand what risk they pose to the environments we protect.
