Flipper Zero: System & Wi-Fi Sniffer Script

A PowerShell-based system and network information gathering script designed for educational and authorized testing purposes only. This script collects basic system, network, and Wi-Fi details from a Windows machine.

⚠️ Disclaimer: This tool is provided for educational and legitimate security assessment purposes only. The author is not responsible for any misuse, damage, or illegal activities conducted with this script. Use only on systems you own or have explicit permission to test.

📁 Script Overview

This repository contains a PowerShell script that runs via a Flipper Zero BadUSB payload (system_sniffer.txt). The script gathers:

• System Info: Computer name, username, OS, uptime
• Network Info: Public IP, local IP, MAC address, gateway
• Wi-Fi Info: Current SSID, BSSID (MAC), signal strength
• Process Info: Top 5 processes by CPU usage

⚠️ IMPORTANT: Currently, the script does NOT output Wi-Fi passwords as this requires administrator privileges. UAC/admin rights bypass is under development. If you have information on how to implement this safely and legally — please share via Issues or Pull Requests!

🚀 How to Use

1. Prepare the Flipper Zero

• Copy the content of system_sniffer.txt to a .txt file on your Flipper Zero SD card under the badusb folder.
• Rename the file with a .txt extension if needed.

2. Execute the Payload

• Plug the Flipper Zero into the target Windows computer.
• Navigate to the BadUSB app on your Flipper.
• Select the system_sniffer.txt payload.
• The script will automatically open PowerShell and execute.

3. View the Output

• The script runs in a visible PowerShell window.
• Information is displayed in colored sections.
• Press any key to exit when done.

---

🔧 How It Works

The script is Base64-encoded within the BadUSB payload to avoid command length limits and improve reliability. It decodes and executes a PowerShell script that:

• Uses native Windows commands (ipconfig, netsh, Get-WmiObject)
• Tries multiple regex patterns to extract network info reliably
• Does NOT extract Wi-Fi passwords without admin rights (in current version)
• Displays results in a structured, color-coded format

---

🔓 Limitations & Development

Current Limitations:

1. Wi-Fi passwords are NOT extracted — requires administrator privileges
2. No UAC bypass in current implementation
3. Basic information gathering only, no privilege escalation

Planned Improvements:

• UAC bypass for extracting saved Wi-Fi passwords
• Additional system information collection
• Results export to file

Need help! If you know safe and legal methods for UAC bypass/obtaining Wi-Fi passwords without admin rights — please share in Issues! This is purely an educational project.

⚠️ Legal & Ethical Warning

• Use only on systems you own or have written permission to test.
• Unauthorized use may violate laws and policies.
• This tool does NOT hide itself — it runs in a visible window.
• Extracting passwords without permission is illegal!
• The author assumes NO liability for any damages or legal issues arising from misuse.

🛡️ Security Notes

• The script does NOT exfiltrate data — it only displays it locally
• Does NOT extract passwords without explicit administrator rights
• Runs entirely in memory (temp file is deleted after execution)
• All operations are transparent and visible to the user
