Re: motors from two French automakers
"a few years ago there was a fun hack that allowed remote access to the complete system on every Dodge, Chrysler, and Jeep from certain generations"
This was a proof of concept never seen in the wild, and there was some suspicion about the story given the people claiming to be able to do it refused to release the part of the method that was remarkable - the wifi exploit had been known for a while, it was the privilege escalation that only they could do. Since we haven't seen it in the wild since then, my guess is it wasn't actually a practical attack - if it was real at all.
