Car Relay Attack System: Everything You Need to Know
Car Relay Attack System: Everything You Need to Know
What is a Car Relay Attack System?
A relay equipment is a paired equipment that relays the transmission between a vehicle remote and the automobile. This equipment uses paired equipment working in tandem to transmit signals over extended ranges.
Relay attack systems are typically utilized by penetration testers to assess security flaws in keyless entry systems.
How Does a Relay Attack Device Work?
The attack device works using paired devices that work together:
- Primary unit is placed near the remote key (at home)
- Second device is placed near the target vehicle
- Primary unit detects the transmission from the key fob
- The transmission is sent to secondary unit via RF link
- Second device sends the code to the vehicle
- The car believes the key is in proximity and unlocks
