A while back @mintynet had his car stolen in a keyless theft. He called me in as a #canbus guru to help work out how exactly the car was stolen, and now we know exactly how they did it and also how to stop them. We call it "CAN Injection 🚘💉" and I've written the whole story up in a blog post: https://kentindell.github.io/2023/04/03/can-injection/
CAN Injection: keyless car theft

This is a detective story about how a car was stolen - and how it uncovered an epidemic of high-tech car theft. It begins with a tweet. In April 2022, my friend Ian Tabor tweeted that vandals had been at his car, pulling apart the headlight and unplugging the cables.

@mintynet @kentindell PIC18F readout protection shouldn’t require anything more destructive than (at most!) desoldering the target. do you have an full part number you can share? :)
@mintynet @kentindell interesting - that's the same one used in those cheapo "ELM327" serial-and-or-bluetooth <-> CAN adapters all over ebay.
