bri3d·Nov 2, 2021
I have been reverse engineering automotive ECUs for a while now - https://github.com/bri3d/VW_Flash . It's a nice change from my day job in enterprise engineering management, and I've met some fun people and taught several folks a lot of new concepts, which is always extremely rewarding. My latest project has been reverse engineering the data-flash encryption in Simos18 ECUs. After some work, it oddly appears the encryption algorithm used is Mifare Hitag2. I'm hoping to be able to re-encrypt NVRAM channels soon, although the overall data flash "filesystem" / channel-system layout needs some more work before I am ready to release my findings.
