CAN Injection: keyless car theft
This is a detective story about how a car was stolen - and how it uncovered an epidemic of high-tech car theft.
Now that people know how a relay attack works generally possible to defeat it: car owners keep their keys in a metal box (blocking the radio message from the car) and some car makers now supply keys that go to sleep if motionless for a few minutes (and so won’t receive the radio message from the car). Faced with this defeat but being unwilling to give up a lucrative activity, thieves moved to a new way around the security: by-passing the entire smart key system. They do this with a new attack: CAN Injection.
