Car Relay Attack System: Complete Information

What is a Relay Equipment?

A relay attack device is a paired device that extends the communication between a vehicle remote and the vehicle. This equipment uses paired equipment working together to relay signals over extended ranges.

Relay attack systems are primarily used by penetration testers to evaluate weaknesses in proximity keys.

How Does a Relay Equipment Work?

The attack device functions using two separate units that coordinate:

1. Unit 1 is placed near the car key fob (in building)
2. Unit 2 is located near the car
3. Primary unit captures the transmission from the remote
4. The signal is sent to secondary unit via RF link
5. Unit 2 sends the transmission to the car
6. The automobile thinks the key is close and unlocks
