DisGuard 🛡️

DisGuard is a lightweight Windows application designed to protect your Discord tokens from being stolen by malicious programs. It watches important Discord folders and running programs in real-time, stopping suspicious activity immediately and blocking their network access. Your tokens stay safe, and you stay worry-free.


Why Should You Care? 🤔

Your Discord token is basically the key to your account — anyone who steals it can pretend to be you, send messages, access servers, and more. Malware authors want these tokens badly.

Even though token stealing is fast, it’s not instantaneous. The attacker needs to:

  • Notice and open the token file,
  • Read the token data,
  • And then send it over the internet to themselves.

Depending on your computer and internet speed, this whole process usually takes somewhere between 50 and 200 milliseconds (that’s 0.05 to 0.2 seconds).

DisGuard’s job? To detect any suspicious activity within a few milliseconds and shut it down before the token leaves your PC. 🎯


How Does DisGuard Work? 🔍

1. Real-Time Folder Watching 👀

DisGuard constantly keeps an eye on all Discord folders where token data might be stored:

  • %APPDATA%\Discord
  • %LOCALAPPDATA%\Discord
  • %LOCALAPPDATA%\DiscordCanary
  • %LOCALAPPDATA%\DiscordPTB

It uses a special Windows feature called ReadDirectoryChangesW that lets it get instant alerts whenever files change in these folders — like when a token file is accessed or modified.

This means DisGuard notices suspicious file activity almost immediately — way faster than human reaction time.

2. Process Scanning 🕵️‍♂️

Every quarter of a second (~250 ms), DisGuard scans all running programs to find suspicious ones. It looks for things like:

  • Processes with names including “inject”, “grabber”, or “discordstealer” (common in malware),
  • And checks if they are digitally signed by trusted companies (like Microsoft). If trusted, it lets them be.

If a program looks fishy and isn’t signed, DisGuard kills it right away — no questions asked.

3. Firewall Blocking 🔥

Killing the process isn’t always enough — the malware might try to restart or communicate with servers.

So DisGuard adds special firewall rules that block all network traffic to and from the suspicious program’s executable file. This cuts off any chance of data sneaking out.

4. Notifications & Tray Icon 💬

You’ll get a quick popup notification letting you know if something suspicious was detected and blocked. Plus, there’s a tray icon where you can:

  • Show or hide the console,
  • Exit DisGuard cleanly.

Design Philosophy ⚙️

  • User-mode only: No complex drivers, easier to install and safer.
  • Minimal dependencies: Written with native Windows APIs for reliability and speed.
  • Multithreaded: Uses separate threads to watch folders and scan processes without slowing down your computer.
  • Trust-based filtering: Avoids bothering legitimate software by verifying digital signatures.
  • Layered protection: Combines file watching, process termination, and firewall blocking for maximum security.
  • Lightweight UI: Custom popup windows and tray icon for a smooth experience with minimal resource usage.

How Well Does It Perform? 🚀

Metric Typical Value
File change detection delay Less than 1 millisecond
Process scan interval ~250 milliseconds
Firewall rules application time Less than 500 milliseconds
Token theft total time (read+send) ~50-200 milliseconds
CPU usage during idle Less than 1%
Memory usage Under 10 MB

In other words: DisGuard acts way faster than most token stealers can finish their job. 🏃💨


Real-World Effectiveness ✨

Even in 2025, token grabbers remain a threat — many use JavaScript injection into Discord's files (core.asar, index.js), or read from the LevelDB database to extract sensitive data.

Here’s why DisGuard still works against the latest techniques:

Threat Type ✅ Status How DisGuard Protects
JS injection into core.asar, index.js Blocked Monitors Discord folders and blocks any process accessing these files.
LocalStorage / LevelDB token grabbing Blocked Detects .ldb, .log, and LevelDB file access instantly.
Malicious executables (e.g. grabber.exe) Blocked Scans processes for suspicious names or unsigned code and terminates them.
Untrusted unsigned processes Blocked Only digitally signed/trusted software is allowed; others are killed on detection.
Exfiltration via HTTP Blocked Adds dynamic Windows Firewall rules to block all network traffic from suspicious apps.

DisGuard typically reacts within 1–3 milliseconds, while modern token stealers usually need 50–200ms to read and transmit tokens — giving DisGuard the edge to stop them before exfiltration happens.


Troubleshooting & FAQs ❓

Q: Why do I need to run DisGuard as Administrator?
A: Admin rights are required to terminate processes and create firewall rules effectively.

Q: Will DisGuard affect legitimate software?
A: DisGuard skips digitally signed and trusted executables to prevent false positives.

Q: What if I want to stop DisGuard?
A: Right-click the tray icon and select “Exit” to safely close the app.


Getting Started: Step-by-Step Guide 📝

System Requirements

  • Windows 10 or later (64-bit recommended)
  • Administrative privileges (needed to stop suspicious processes and add firewall rules)
  • At least 2 GB RAM and minimal CPU usage (DisGuard is lightweight!)

How to Install & Run DisGuard

  1. Download the latest release
    Head over to the Releases page and download the latest DisGuard.exe zip package.

  2. Extract the zip file
    Extract all files to a folder you prefer, e.g., C:\Program Files\DisGuard.

  3. Run as Administrator
    Right-click DisGuard.exe and select Run as administrator.
    This is essential for the app to monitor system processes and manage firewall rules properly.

  4. Check the system tray
    After launch, DisGuard will minimize to your system tray (near the clock).

    • Left-click the tray icon to show or hide the console window.
    • Right-click for options like Exit.
  5. Enjoy peace of mind!
    DisGuard will now silently watch your Discord folders and processes for suspicious activity, notifying you instantly of threats.


How to Build DisGuard from Source 🛠️

If you want to compile DisGuard yourself:

  1. Clone the repository
    Open a terminal and run:

    git clone https://github.com/PwnTheStack/DisGuard.git
    cd DisGuard
  2. Open the solution
    Open the DisGuard.sln file using Visual Studio 2022 or any compatible C++ IDE that supports Windows desktop development.

  3. Set build configuration
    In Visual Studio, select the build configuration to Release and target platform to x64 (recommended for performance and compatibility).

  4. Build the project
    Use the menu option Build > Build Solution or press Ctrl + Shift + B to compile the project.

  5. Run as Administrator
    After a successful build, navigate to the output folder (usually DisGuard\Release\x64\) and run the compiled executable with Administrator privileges. Right-click the .exe file and select Run as administrator.
    This is required so DisGuard can monitor processes and add firewall rules.
