Crafty criminals have resorted to using specially crafted devices that simply plug into the wiring harness behind the headlight of a victim’s car.
The device’s programming is set up to inject fake Controller Area Network (CAN bus) messages into the car’s actual CAN Bus network. Once they’re plugged in, they’re able to unlock, start, and drive away before the owner even catches wind of what’s going on. Given that the manufacturer of these CAN injection devices claims that the devices are so effective against a myriad of makes and models, it would seem that this could be an industry-wide problem that may take some brainstorming to fix.
