# OSINT Industries CTF - Writeups

Welcome to my collection of writeups for the OSINT Industries CTF challenges.

This GitBook documents my thought process, tools, techniques, and methodologies used to solve various Open-Source Intelligence (OSINT) challenges. The goal is not just to show the final answer, but to explain how and why each step was taken — so others can learn and apply the same approaches in real-world investigations or future CTFs.

### 📌 What You’ll Find Here

* Step-by-step OSINT investigations
* Tool usage (search engines, social platforms, metadata tools, archives, etc.)
* Reasoning behind each pivot and lead
* Screenshots, references, and validation methods
* Lessons learned and alternative approaches (when applicable)

### 🎯 Purpose of This Writeup Collection

* 🧠 Improve my OSINT and investigative skills
* 📚 Serve as a personal knowledge base and reference
* 🤝 Help other learners understand OSINT workflows
* 🏁 Document CTF progress and problem-solving strategies

These writeups are meant to be educational and transparent, not just solution dumps.

### ⚠️ Disclaimer

All challenges and data discussed here are part of legal, authorized CTF exercises.

No real-world harassment, doxxing, or illegal investigation techniques are encouraged or supported.

Use OSINT responsibly and ethically.

### 🛠 Tools Commonly Used

Some tools and techniques you may see across the writeups:

* Google Dorking & advanced search operators
* Social media and username enumeration
* Reverse image search
* Metadata analysis
* Archive services (Wayback, caches, mirrors)
* Public records and open databases

### 📂 Structure

Each challenge usually includes:

* Challenge overview
* Initial assumptions
* Investigation process
* Key findings
* Final flag / answer
* Notes & takeaways

### 🚀 Final Notes

If you’re learning OSINT, doing CTFs, or just curious about how digital investigations work — I hope this helps you in some way.\
