FORCE: A Powerful Tool for RF Signal Analysis and Penetration Testing

A breakthrough device for analyzing, testing, and exploiting vulnerabilities in 315 MHz and 433 MHz remotes.

What is FORCE?

A few months ago, I set out to build a project from scratch to improve my programming and PCB design skills. That project became FORCE—a powerful device designed for RF security research and penetration testing.

Key Features of FORCE

🔹 Brute Force Attack

FORCE can perform a brute-force attack on 315 MHz or 433 MHz frequencies, cycling through possible remote control codes to test the security of RF-based systems.

🔹 Signal Analyzer

If you have an unknown remote and don’t know its frequency, FORCE can help. Enter the analyzer mode, hold down a button on your remote, and FORCE will detect and analyze its frequency and RSSI (signal strength).

🔹 Replay Attack – Exploiting a Common Vulnerability

One of FORCE’s most powerful features is its ability to perform a replay attack.

How Does the Vulnerability Work?

Many 315 MHz and 433 MHz remotes still use fixed codes, meaning they send the exact same signal every time a button is pressed. This allows an attacker to record the signal and replay it later—essentially cloning the remote.

How FORCE Uses This Vulnerability

• FORCE captures the remote’s RF signal, protocol, and bit sequence.
• It then retransmits the signal, allowing it to act as the original remote.
• This technique can be used to test whether a system is vulnerable to RF replay attacks.

If a remote is vulnerable, the best solution is to switch to a rolling code system that changes with every button press, making replay attacks impossible.

Advanced Firmware Update System

FORCE includes an easy-to-use OTA (Over-the-Air) update feature. Here’s how it works:

1. When you enter update mode for the first time, FORCE will display:

   • WiFi SSID (network name)
   • Password
   • IP Address

2. Connect to the WiFi network created by the ESP32.

3. Open a browser and go to the IP address displayed on the screen.

4. A list of available WiFi networks will appear—select yours, enter the password, and FORCE will save these settings for future updates.

This means you can update FORCE wirelessly, without needing a USB connection.

Upcoming Updates 🚀

FORCE is just getting started! I have huge updates planned.

The updates will make FORCE an even more powerful tool for RF security analysis.

Final Thoughts

FORCE is more than just a project—it’s a game-changing tool for RF security testing. Whether you’re analyzing remote signals, testing system vulnerabilities, or just exploring RF technology, FORCE provides a powerful and easy-to-use solution.
