Reverse-engineering simple wireless devices

kliment

I'll walk you through the reverse-engineering of a handful of simple mass-produced cheap wireless devices including several kinds of wireless doorbell and a wireless motion detector. I'll show you how to find signals on a PCB without a schematic, how to decode them, and how to interpret and generate them. After that, I'll give a short discussion on the security and privacy aspects of even simple devices like these, which are often overlooked.
