All German Automobile Federation "ADAC"In order to raise awareness of theft prevention by revealing the actual situation that cars are being stolen easily by hacking smart key, the smart key of 24 car models of 19 world famous car manufacturers is called "amplification attack ) "Hacking experiment was carried out.

In the smart key system, "When the car's sensor sends a signal and the smart key that received the signal returns a response signal, the car recognizes that there are drivers with keys inside the car and allows the engine to turn on" A mechanism is taken. By exploiting this system, it amplifies the signal sent by the automobile sensor, sends a signal to the remote smart key, and disguises the driver as if it is inside the car and plays the engine. It is an attack.

In a signal amplification attack, as long as the smart key is at a certain distance from the car, the thief can easily steal the car if it penetrates into the car. In other words, when a luxury car that is always parked at the same parking lot is aimed at, it is difficult to take measures as there is pointed out that there is only one way to protect the smart key by putting it in the refrigerator and blocking the signal.

The aim is to raise the accuracy by targeting the car's smart key to steal.

Citroen:DS4 CrossBack
Ford:Galaxy, Eco-Sport
Hyundai:Santa Fe CRDi
Lexus:RX 450 h
