Browser-Based Malware Detection System Using JavaScript Behavior Monitoring

This project focuses on developing a browser-based malware detection system that monitors JavaScript execution behavior. The system detects malicious scripts embedded in websites that attempt drive-by downloads, data theft, or unauthorized redirections.

Study browser architecture and JavaScript execution environments.

Research common web-based malware techniques such as malicious scripts and exploits.

Design a monitoring system to log JavaScript behavior in a sandboxed environment.

Identify suspicious patterns such as hidden iframe injection or obfuscated scripts.

Implement heuristic-based detection logic.

Develop a browser extension prototype for real-time detection.

Create alerts for suspicious web pages.

Test with safe simulated malicious scripts.

Evaluate detection performance and user experience impact.

Document security implications and deployment considerations.
