🔐 Secure File Upload and Malware Scanning

A full-stack project for the CyberXplore Developer Challenge. It allows users to upload files (PDF, DOCX, JPG, PNG), simulates malware scanning asynchronously using RabbitMQ, and displays real-time scan results on a responsive dashboard.

📌 Features

• File Upload (max 5MB)
• Asynchronous Malware Scanning (via RabbitMQ)
• MongoDB for metadata storage
• Real-Time Dashboard
• Clean,Infected, Pending file status
• Optional Slack/Webhook notifications for infected files

Run Locally

Clone the project

  git clone https://github.com/sumitprajapati1/file-scanner.git

Go to the project directory

  cd file-scanner

Install Backend dependencies

  cd server
  npm install

Create .env file

PORT=3000
RABBITMQ_URL=amqp://localhost:5672 ( mostly this )
MONGODB_URI= your_local_url 

Start Local RabbitMQ (Windows):

Step 1: Install RabbitMQ from website

Step 2: Run below command in cmd administrator

rabbitmq-plugins enable rabbitmq_management

rabbitmq-server

Access RabbitMQ UI at: http://localhost:15672 Login: guest / guest

Now Start the server

  npm run dev:all 

Install Frontend dependencies

cd client1
npm install
npm run dev 

How Scanning Works

File metadata is stored in MongoDB.

A job is queued to RabbitMQ.

Worker simulates scanning using setTimeout(2–5s).

File is marked:

clean if no keywords

infected if it contains rm -rf, eval, or bitcoin

MongoDB is updated with results.

Dashboard updates every 5–10s to reflect status.
