tl;dr if you have physical access to the CAN bus, you can cause enough errors to render it inoperable, by tampering with CAN frames and flipping bits around.
If you have physical access to the CAN bus you can also make it inoperable by shorting the two wires together... not sure the takeaway is supposed to be with this.
- schwarrrtz 9y agoThe takeaway is that by tampering only with CAN messages sent by a particular system, you can force that system to disconnect from the network. For example, an attacker might use this exploit to disable the airbag, or disable the engine while the car is driving, or cause other safety problems.
