Doorbell Relay
Estimated Time: ~10 minutes
Summary
This lab demonstrates wireless relay and replay attack concepts using simulated OOK/ASK doorbell transmissions.
The objective is to understand how simple RF devices can be analyzed and replayed.
Launching the Lab
Start SDRForge:
python3 SDRForge.py
Select:
Doorbell Relay
Selection
- See the Signal - This allows you to see the wave, and peaks in a waterfall
- How it's done - This allows you to see the radio thats conducting this attack
Interface Overview
The lab includes:
- Waterfall display - shows real time fake signals coming through
- Relay controls - you can change the input in the radios vector
- Timing analysis - time out each burst
Capturing a Signal
The simulated doorbell transmission appears in the analysis panel.
Understanding Relay Attacks
Basic workflow:
- Capture transmission
- Analyze pulse timing
- Store signal pattern
- Replay signal
- Trigger receiver
Educational Notes
This simulation does not transmit RF signals.
The purpose is to demonstrate wireless attack concepts safely and legally.
Troubleshooting
Waterfall not moving
