Having worked in and around the car industry the best part of 27 years prior to my current role, (running an IT company) I think, like the responder says of himself and their insider expertise, I know my way around both the industry, concept and the technicalities.
The only publicised and technically detailed case in on Toyotas and specifically a RAV4. Outside that it is a lot of fluff and circumstance from people “doing their own research” or dark web braggarts.
The breakdown was done by one of the original CAN designers, who likely knows a lot more about this than any of us. This RAV4 specific convo has been around for some time to industry followers.
Enjoy. Given the OP was asking about their own vehicle that is neither very old Cali nor a RAV4, the original response stands IMHO. Keep your key safe, realise anything other that that is for your own (valid) peace of mind.
We don’t “all know” that a Cali (of any age) can have a CAN injection to defeat the immobiliser, mainly because you can’t and it’s twaddle. There are zero examples of this anywhere. I could say I learnt that from a mythical VW Mastertech, but then I would be hiding behind being “allowed” to give any details, because I haven't spoken to this person.
The JLR scandal mentioned is actually relay theft from keys, on older Land and Range Rovers, fixed some time ago (approx 24 months) by JRL with a more sophisticated algorithm and with a key hardware update to one that goes to sleep. JLR were very upfront about the flaw, not unique to them, and the fix.
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.
