lecture: Reversing an IoT smarthome system
Radio, MitM and Firmware hacking for fun and sovereignty
Despite my protest we have now an IoT system controlling the heating at home. At least I now have something to play with. This is an ongoing project, i'll present my results so far.
This particular smarthome system is a classical IoT setup, we have devices which control some aspect of our home (mostly temperature), these communicate with a central controller over 868.xxx MHz providing opportunities to mess around with SDRs. This central controller communicates with a server in the cloud, using some ancient encryption protocol, providing even more fun opportunities to mess with MitM attacks and cryptanalitics, Last but not least the physical control over the central controller also allows for messing directly with its hardware and its firmware providing months of fun for the RE connoisseur. In the end I might be able to cut off the whole thing from the cloud and take control over the whole setup myself. We'll see how far I got. Loads of fun for sure.
