"But it could also have been that they put the entire bus in a giant Faraday cage"
And that's what they did. If that was necessary for the conclusions is not said in the article. Only that the remote access could
- Update software (well, that's pretty common)
- Diagnosis (ditto), and
- Manage the control system for battery and power supply.
The conclusion by the team was that the buses can be remotely stopped or bricked by the manufacturer.
Bricking a bus via remote software update is easy. What is hard is remotely updating a vehicle and not bricking any of them. I'm under NDA so lets just say it is hard to get something that passes our test group when we are trying to make things work correctly. Trying to brick a vehicle is easy mode. (now if you want to brick it in a specific way that can be hard)
