Relay Attack Device: Complete Information

What is a Relay Attack Device?

A relay equipment is a dual-unit device that extends the transmission between a key fob and the car. This technology uses paired equipment working in tandem to forward signals over extended ranges.

Relay devices are primarily used by penetration testers to test weaknesses in smart key technology.

How Does a Relay Attack Device Work?

The relay system works using paired devices that coordinate:

First device is positioned near the key fob (at home)
Secondary unit is positioned near the target vehicle
Unit 1 receives the signal from the key fob
The signal is relayed to Unit 2 via wireless connection
Secondary unit sends the code to the automobile
The car assumes the remote is in proximity and unlocks
