As long as the control systems are properly air-gapped you should be fine. (doesn't work for jeep apparently due to cost savings... https://www.wired.com/2015/07/hackers-remotely-kill-jeep-hig...)

won't stop someone physically breaking in and connecting something to the bus but the alarm should sound in that case.

Well, it's a 2-step process. It's hard to find a car without remote-unlock. From there, you have access to OBD.

OBD port is +12, GND, TX and RX pin if you just want to connect to 1 bus. Shouldn't be too hard MITM that if you have physical access.

1. Remote unlock - you need to hack that... good luck...

2. ODB port requires physical access which means either alarm or 1... under pressure since owner may see you and call cops.

Now you can do something else on cheap asshole car manufacturers like Jeep and bluetooth/wifi hack media center then get on ODB via that because cheap idiots said its a good idea to have common bus.

Iunno, #1 followed by #2 has been happening with some frequency with high end vehicles.

But moreso to steal them in the middle of the night and have in a sea container within 24h.

Then again, if it was being done to install a MITM OBD device... it’s a lot less obvious than waking up to your car gone.

Unplug the antenna?

And someone that's going to MITM your OBD could also MITM your ignition wire on an analog car.

There have been cars where the bus connection to the ABS system was accessable in the wheel well.

Yeah, but you need physical access and unlocked car... you can cut the breaks too if you have that...
