Car Relay Attack System: Complete Information
What is a Car Relay Attack System?
A relay attack device is a two-part equipment that relays the signal between a key fob and the vehicle. This technology uses dual units working together to forward signals over long distances.
Relay devices are typically utilized by automotive professionals to test weaknesses in keyless entry systems.
How Does a Relay Equipment Work?
The attack device works using two separate units that coordinate:
- Primary unit is positioned near the remote key (at home)
- Unit 2 is located near the automobile
- Primary unit receives the communication from the remote
- The signal is relayed to secondary unit via data transmission
- Unit 2 broadcasts the transmission to the vehicle
- The car assumes the key fob is in proximity and unlocks
