Vehicle Relay Equipment: Complete Information

What is a Car Relay Attack System?

A car relay attack system is a dual-unit device that bridges the signal between a vehicle remote and the automobile. This equipment uses paired equipment working in tandem to forward signals over greater distances.

Relay devices are primarily used by security researchers to test weaknesses in smart key technology.

How Does a Relay Attack Device Work?

The relay attack operates using paired devices that work together:

  1. First device is located near the car key fob (at home)
  2. Second device is positioned near the automobile
  3. Primary unit captures the transmission from the remote
  4. The signal is transmitted to second device via data transmission
  5. Unit 2 sends the transmission to the car
  6. The automobile assumes the key fob is close and grants access
