Relay Attack Device: Complete Information

What is a Relay Equipment?

A relay equipment is a dual-unit equipment that extends the communication between a car key fob and the automobile. This equipment uses paired equipment working in tandem to transmit transmissions over greater distances.

Attack equipment are primarily used by security researchers to evaluate vulnerabilities in keyless entry systems.

How Does a Relay Equipment Work?

The relay system works using two separate units that communicate:

1. Unit 1 is positioned near the car key fob (in building)
2. Secondary unit is located near the target vehicle
3. First device receives the signal from the remote
4. The data is relayed to second device via wireless connection
5. Secondary unit broadcasts the signal to the vehicle
6. The automobile believes the key is in proximity and unlocks
