Vehicle Relay Equipment: Everything You Need to Know
What is a Car Relay Attack System?
A car relay attack system is a dual-unit device that relays the communication between a car key fob and the vehicle. This equipment uses paired equipment working together to relay signals over extended ranges.
Relay devices are commonly employed by penetration testers to evaluate vulnerabilities in keyless entry systems.
How Does a Relay Attack System Work?
The relay system functions using dual components that work together:
- Primary unit is positioned near the key fob (at home)
- Unit 2 is placed near the automobile
- Unit 1 captures the signal from the key fob
- The signal is transmitted to secondary unit via RF link
- Secondary unit broadcasts the code to the automobile
- The car assumes the remote is nearby and unlocks
