DisWarden - The Anti-Malware Discord Bot!

Created by PixelRidge Softworks

DisWarden is a Discord bot designed to enhance server security by scanning files, images, and links shared within the chat. Utilizing the robust capabilities of VirusTotal and OPSWAT MetaDefender, DisWarden ensures that all shared content is free from malware and safe for community members. In scenarios where rate limits affect our primary scanning service, the bot smartly falls back to an alternative service, guaranteeing continuous protection.

  • Malware Scanning: Automatically scans all files and images shared in the chat for malware.
  • Link Reputation: Checks the reputation of URLs to protect against phishing or spoofed links.
  • Rate Limit Management: Seamlessly switches between VirusTotal and OPSWAT MetaDefender in case of rate limiting.
  • Queue System: Temporarily queues files for scanning if both services are unavailable, retrying at a later time.
  • Ruby-based: Developed in Ruby using the discordrb library for efficient and reliable bot operations.


Before you install DisWarden, ensure you have the following:


Clone the repository to your machine/vps:

git clone
cd DisWarden

Install the required gems:

bundle install

Configure your environment variables. Rename .env.example to .env and fill in your Discord Bot Token, VirusTotal API Key, and OPSWAT MetaDefender API Key.

Run the bot:

ruby runner.rb


Once DisWarden is up and running, it will automatically start scanning any files, images, and links shared in your Discord server's text channels. If a threat is detected, the bot will alert the channel and provide advice on how to proceed.
