Relay Attack Device: Complete Information

What is a Car Relay Attack System?

A relay attack device is a dual-unit equipment that relays the signal between a car key fob and the car. This technology uses paired equipment working in tandem to relay signals over greater distances.

Relay attack systems are typically utilized by security researchers to test weaknesses in proximity keys.

How Does a Relay Attack System Work?

The relay attack works using two separate units that coordinate:

1. Primary unit is located near the car key fob (in building)
2. Unit 2 is placed near the target vehicle
3. Primary unit detects the transmission from the car key
4. The transmission is sent to second device via wireless connection
5. Unit 2 sends the code to the automobile
6. The car believes the key is nearby and opens
