Relay Attack Device: Everything You Need to Know

What is a Relay Attack Device?

A relay attack device is a dual-unit equipment that relays the transmission between a vehicle remote and the vehicle. This system uses paired equipment working in tandem to forward signals over long distances.

Attack equipment are commonly employed by security researchers to evaluate vulnerabilities in smart key technology.

How Does a Relay Equipment Work?

The relay system functions using paired devices that work together:

Primary unit is positioned near the remote key (in building)
Secondary unit is located near the car
Primary unit captures the transmission from the key fob
The transmission is transmitted to second device via wireless connection
Secondary unit broadcasts the signal to the car
The car thinks the key fob is in proximity and grants access
