About

This project is a comprehensive malware detection system developed as part of a semester project. It combines machine learning with web technologies to provide safe, static analysis of executable files, featuring a React frontend, FastAPI backend, and ML-powered detection engine.

The system analyzes Portable Executable (PE) files using static features extracted without executing the binaries, ensuring 100% safety. It employs a Support Vector Classifier (SVC) trained on a dataset of benign and malicious samples, achieving 62.5% test accuracy. The web interface allows users to upload files, perform batch scans, and view analytics, all while maintaining secure, localhost-only deployment.

Key technologies include Python for ML and backend, React for the frontend, PostgreSQL for data storage with Supabase failover, and YARA for signature-based detection.

✨ Key Features

🔒 Static Analysis Only - PE file parsing without executing binaries (100% safe)
🤖 SVC Machine Learning - Support Vector Classifier with 62.5% test accuracy
⚡ FastAPI Backend - 15+ REST endpoints with automatic Swagger documentation
🖥️ React Frontend - Modern web interface with authentication and analytics
🔍 Multi-Scan Types - Single file, batch, ZIP archives, and system-wide scanning
💾 PostgreSQL Database - Persistent scan results and user authentication with automatic Supabase failover
🔐 JWT Authentication - Secure user login and registration
📊 Analytics Dashboard - Real-time statistics and prediction history
🎯 YARA Rules - Additional signature-based detection

📦 Production Ready - Fully trained, tested, and documented

🗄️ Database Failover System

The system implements automatic database failover between PostgreSQL and Supabase:

Primary Database: PostgreSQL (local or remote)
Failover Database: Supabase (cloud PostgreSQL)
Automatic Switching: When PostgreSQL is unavailable, the system automatically switches to Supabase
Health Monitoring: /health endpoint shows current database status
Configuration: Set SUPABASE_URL and SUPABASE_DB_PASSWORD in .env file

# Example .env configuration
DATABASE_URL=postgresql://user:pass@localhost:5432/malware_db
SUPABASE_URL=https://your-project.supabase.co
SUPABASE_DB_PASSWORD=your-db-password
USE_SUPABASE_AS_FAILOVER=true

Deployment Notes

Current Setup (Development):

✅ Localhost only (secure)
✅ Single worker process
✅ SQLite database for scan results
✅ Debug mode OFF
✅ Safe for learning/testing

Production Deployment Would Require:

Add HTTPS/SSL certificates

Implement rate limiting
Add authentication/API keys
Use reverse proxy (Nginx)
Database for logging
Error monitoring (Sentry)

ML Model Safety

✅ Static Analysis Only - No file execution ✅ No Sandbox Evasion - Pure PE analysis ✅ Academic Safe - Educational use only ✅ NOT Antivirus - Does NOT replace security software

📈 Features Extracted

The system analyzes 5 key PE file characteristics:

File Size - Executable size in bytes
Number of Sections - PE section count
Entry Point - Entry point address
Image Base - Base memory address
Number of Imports - Imported function count

- Uses pefile to parse PE executables
- Extracts 5 features without execution
Dataset Preparation (ml/training/prepare_data.py)
- Loads samples from benign/ and malware/ folders
- Normalizes features for training
Model Training (ml/training/train_model.py)

Trains both RandomForest and SVC classifiers
Compares models and selects best (currently SVC)
Saves trained models to pickle files

API Integration (backend/app/ml_service.py)
- Loads trained model (best model)
- ✅ Input validation with Pydantic
