Relay Attack Device: Full Guide
What is a Relay Equipment?
A car relay attack system is a two-part equipment that relays the transmission between a car key fob and the vehicle. This technology uses two devices working together to transmit communications over long distances.
Attack equipment are primarily used by penetration testers to test security flaws in keyless entry systems.
How Does a Relay Attack Device Work?
The relay attack operates using dual components that coordinate:
- Unit 1 is positioned near the key fob (at home)
- Second device is positioned near the target vehicle
- Unit 1 captures the communication from the remote
- The data is transmitted to second device via wireless connection
- Unit 2 transmits the signal to the car
- The car assumes the remote is in proximity and opens
