Vehicle Relay Equipment: Complete Information
What is a Relay Attack Device?
A car relay attack system is a dual-unit system that bridges the signal between a vehicle remote and the automobile. This system uses paired equipment working simultaneously to transmit transmissions over long distances.
Relay attack systems are commonly employed by security researchers to evaluate security flaws in proximity keys.
How Does a Relay Attack System Work?
The attack device functions using paired devices that communicate:
- First device is positioned near the remote key (at home)
- Second device is positioned near the target vehicle
- Primary unit captures the signal from the car key
- The transmission is relayed to second device via wireless connection
- Secondary unit sends the transmission to the car
- The automobile thinks the remote is nearby and opens
