Car Relay Attack System: Complete Information

What is a Relay Equipment?

A relay attack device is a paired system that extends the transmission between a key fob and the car. This technology uses dual units working simultaneously to relay communications over greater distances.

Attack equipment are commonly employed by security researchers to test security flaws in smart key technology.

How Does a Relay Attack Device Work?

The relay attack operates using dual components that coordinate:

1. Unit 1 is positioned near the key fob (at home)
2. Secondary unit is placed near the automobile
3. First device receives the communication from the car key
4. The data is transmitted to secondary unit via data transmission
5. Secondary unit transmits the transmission to the car
6. The vehicle believes the key is nearby and opens
