Relay Attack Device: Everything You Need to Know
What is a Relay Attack Device?
A relay attack device is a dual-unit system that bridges the signal between a vehicle remote and the automobile. This equipment uses dual units working in tandem to relay signals over long distances.
Relay devices are typically utilized by security researchers to assess vulnerabilities in proximity keys.
How Does a Relay Attack System Work?
The attack device functions using dual components that coordinate:
- Primary unit is positioned near the car key fob (in building)
- Unit 2 is located near the target vehicle
- First device detects the signal from the key fob
- The data is sent to second device via data transmission
- Second device sends the signal to the automobile
- The automobile thinks the key is in proximity and opens
