Eye-Sint – A Multi-Module Open-Source Intelligence Tool

Eye-Sint was made during my undergrad as a final-year college project, and it became one of the most rewarding technical journeys I’ve had. I always wanted to build something useful in the OSINT and cybersecurity space and Eye-Sint brought both of those passions together.

And in fact, it was awarded Best Project of the 2024 Batch! 🏆

It’s a cloud-hosted, GUI-based OSINT tool developed using Python, Flask, and React.js, capable of performing reconnaissance across the internet. What makes Eye-Sint special is its modular design: it brings together multiple OSINT functionalities that are usually scattered across several tools—all in one place.

🔍 What Can Eye-Sint Do?

• 🌐 Web Scraping: Collects website headers, extracts emails, performs domain lookups, and even brute-forces directories.
• 🧠 Human Footprinting: Gathers information about individuals, performs username lookups, phone number-based geolocation, and extracts PDF metadata.
• 🔐 Port Scanning: Detects open network ports to help with vulnerability assessments.
• 📁 PDF Metadata Extraction: Analyze files for hidden author details, creation dates, and more.
• 🌎 Domain Search: Perform whois lookups and SSL info extraction with just a few clicks.
  
  And the best part? It’s open source, easily extendable, and built to be used by both beginners and pros in the cybersecurity field.

🧪 Built With:

• 🐍 Python (Backend Logic)
• ⚛️ React.js (Frontend UI)
• 🔥 Flask (Web Server & Routing)
• ☁️ Cloud-hosted on Render for public access

📝 Research Publication

I’m super proud to say that our project also resulted in a research paper, titled:

“Enhancing OSINT Practices with Eye-Sint: A Multi-Module Intelligence Tool”
📄 Published in the Indian Journal of Natural Sciences (Vol.14 / Issue 82 / Feb 2024)

This paper explores the technical architecture, methodologies, and comparative evaluation of Eye-Sint against tools like Shodan and Maltego. We also emphasized ethical OSINT, ensuring Eye-Sint encourages responsible data usage, consent practices, and privacy considerations.

🚀 Why I Built This

While my other projects (like One Shop Stop) focused more on web development, Eye-Sint was where I truly started diving deep into cybersecurity. It helped me explore OSINT frameworks, automate repetitive tasks, and apply research knowledge into practice.

I also learned a lot about secure data handling, modular architecture, and open-source collaboration, and I can confidently say this project boosted my technical and professional growth.

“Eye-Sint is more than a project—it’s a personal milestone that blends my passion for security, research, and open-source contribution.”

🧠 What’s Next?

I’m actively working on:

• Adding AI-assisted OSINT automation
• Integrating Maltego-like graphs
• Expanding modules with more social recon features
