Replay Attack on 433MHz/315MHz Frequency using Arduino

This project demonstrates a replay attack using an Arduino board and radio frequency modules operating at either 433MHz or 315MHz (based on the module’s capability). The primary aim is to capture and resend signals at a specific frequency, replicating the behavior of a remote control.

Components Needed

1. Arduino Board: Uno, Nano, or other compatible models.
2. 433MHz/315MHz RF Modules: FS1000A is recommended for its flexibility with both frequencies.
3. Jumper Wires: To connect components.
4. Push Button (2-pin): Used to trigger transmission.
5. Antenna for RF Module (Optional): Improves signal range and reliability.

RF Module FS1000A

This module can operate on both 433MHz and 315MHz frequencies.

Wiring Diagram

The following connections are required for the setup:

1. Arduino Pin 2 → Receiver Input Pin
2. Arduino Pin 3 → Transmitter Input Pin
3. 5V Pin (Arduino) → 5V on both Receiver and Transmitter
4. GND (Arduino) → GND on both Receiver and Transmitter
5. Pin 4 (Arduino) → One side of the push button (Other side to GND)
