USB-Security-Monitor v1.0 - Unauthorized Access & USB Drive Monitor

USB-Security-Monitor v1.0 Release

Overview

USB-Security-Monitor is a lightweight Windows security tool designed to protect your PC from unauthorized access and risky USB insertions. It acts as a boot-time sentinel, enforcing password verification and automated responses to threats. Perfect for shared environments, kiosks, or personal paranoia-proofing!

Key Features

• Boot-Time Password Lock: After 30 seconds of startup, prompts for a normal password. Wrong entry triggers a 2-minute shutdown countdown.
• Emergency Override: During shutdown, enter the emergency password within 2 minutes to cancel the shutdown.
• USB Drive Protection: If enabled, automatically formats any inserted USB drive (NTFS, quick format) and restarts the password prompt + shutdown sequence.
• Stealth Monitoring: Captures screenshots, webcam photos (if enabled), running app titles, and sends alerts via Discord webhook for remote logging.
• Easy Configuration: On first run (or if config file is missing), sets up normal/emergency passwords and Discord webhook. Config stored securely in %APPDATA%\HUK_CHK.NFO (delete this file to reset).
• No Bloat: Built with VB.NET and Emgu.CV for webcam support. Minimal dependencies.

Installation & Setup

1. Download: Grab the USB-Security-Monitor-v1.0.zip from this release.
2. Extract the ZIP:
   • Unzip the file to a dedicated folder, e.g., C:\Program Files\USB-Security-Monitor (create the folder if needed). Avoid spaces in the path for best compatibility.
3. Add to Startup:
   • Press Win + R, type shell:startup, and press Enter to open the Startup folder.
   • Right-click USB-Security-Monitor.exe in the extracted folder > Create Shortcut.
   • Copy the shortcut to the Startup folder.
4. First-Time Setup:
   • Restart your PC – it will prompt for setup on first boot.
   • Enter a strong normal password (daily use).
   • Set an emergency password (shutdown canceler).
   • (Optional) Add a Discord webhook URL for alerts (e.g., from Discord channel settings > Integrations > Webhooks).
5. Enable Options: Launch the app (or via config button) to toggle USB formatting and webcam capture.
6. Reset Config: Forgot passwords? Delete %APPDATA%\HUK_CHK.NFO and relaunch.

Pro Tip: Test in a virtual machine first! Use Task Manager to kill the process if things go sideways.

Usage Notes

• Shutdown Behavior: Uses Windows shutdown /s /t 120 command. Emergency cancel with /a.
• USB Formatting: Irreversible! Only enable if you're sure – it runs format /FS:NTFS /Q /Y silently.
• Dependencies: Requires .NET Framework 4.7+ and Emgu.CV (bundled). Webcam needs a compatible camera.
• Logging: All alerts include IP, hostname, username, timestamp, and app snapshots.

Warnings & Disclaimer

• ⚠️ High Risk: This tool can permanently delete data (USB format) or force shutdowns. Use responsibly – not for production without backups.
• Legal/Ethical: Intended for personal/shared PC protection. Do not deploy on others' systems without consent.

Changelog

• v1.0 (Initial Release): Full implementation with password dialogs, USB watcher, Discord integration, and startup registration support.
• Fixed: Config file handling for %APPDATA% path.
• Added: Webcam initialization checks and error handling.
