Relay Attack Device: Complete Information

What is a Car Relay Attack System?

A car relay attack system is a two-part system that relays the signal between a vehicle remote and the vehicle. This equipment uses paired equipment working simultaneously to transmit transmissions over long distances.

Relay devices are primarily used by penetration testers to test vulnerabilities in proximity keys.

How Does a Relay Attack System Work?

The relay system functions using dual components that coordinate:

1. First device is positioned near the remote key (in building)
2. Secondary unit is located near the car
3. First device receives the transmission from the car key
4. The signal is relayed to second device via RF link
5. Secondary unit broadcasts the transmission to the vehicle
6. The vehicle assumes the key is close and opens
