OBD-II: Obviously Broken Design, Too... My Introduction into car-hacking (emf2026)

Is it still your car? With a modern car running between 100 and 150 small computers - ECUs - the question is hard to answer. In 2015 some hackers took control together with a baffled Wired reporter of the car he was driving, from miles away. This led to a lot more interest in those computers constantly talking to each other over CAN bus. There is a massive playground here and most people do not even know the gate is open. Maybe you already have a Bluetooth ELM-327 dongle visualising CAN data on your smartphone. That is the crack that lets you dig deeper. The next step is the Macchina M2 - which goes so much further. You get direct access to more vehicle interfaces than most hackers even know exist. I will show you SavvyCAN and Wireshark capturing live CAN traffic and we will decode what those packets are actually saying. Your own car, your own hardware, completely legal. By the end of this talk you will want to go straight to the car park and plug something in.
