Relay Attack Device: Full Guide
What is a Car Relay Attack System?
A relay attack device is a two-part device that bridges the transmission between a vehicle remote and the car. This system uses paired equipment working in tandem to forward communications over greater distances.
Attack equipment are primarily used by penetration testers to test security flaws in proximity keys.
How Does a Relay Equipment Work?
The relay system operates using paired devices that work together:
- Unit 1 is positioned near the remote key (in building)
- Unit 2 is positioned near the target vehicle
- First device detects the communication from the key fob
- The transmission is transmitted to second device via RF link
- Unit 2 broadcasts the code to the car
- The automobile thinks the key fob is nearby and unlocks
