Welcome to my CTF Write-Ups Repository! This is where I document my journey through various Capture The Flag (CTF) challenges, focusing on binary exploitation, reverse engineering, and other cybersecurity techniques. The repository is organized by Pwn College courses, serving as a knowledge base for myself and others interested in offensive security.
Each directory corresponds to a Pwn College course/module, containing detailed write-ups for its challenges. Example structure: pwn-write-ups/ ├───Linux-luminarium/ # Write-ups for Linux basics └───... # More to come!
- 📝 Learning Log: Track my progress and reinforce concepts.
- 🔍 Reference: Detailed explanations of techniques (e.g., manpage, file globbing, etc).
- 🌍 Sharing: Help others learn from solved challenges.
- 🏆 CTF Prep: Archive of tricks and tools for future competitions.
- Binary Exploitation: Buffer overflows, format strings, shellcoding.
- Reverse Engineering: Ghidra, IDA Pro, dynamic analysis.
- Web/Pwn: SQLi, XSS, privilege escalation.
- Cryptography: RSA, AES, side-channel attacks.
- Navigate to the relevant course folder.
- Find the challenge name (e.g.,
stack_buffer_overflow.md). - Read the write-up for:
- Vulnerability analysis
- Full Exploit Code:
I’m still learning exploitation techniques, so finished PoCs (Proof of Concepts) aren’t provided. - Mitigation Strategies:
Solutions to patch the vulnerabilities aren’t covered (but might be added later!).
Why? This approach helps me deeply understand vulnerabilities first, before jumping to exploits. As I progress, I’ll expand the scope!
Want to help? PRs with exploit examples or fixes are welcome! 🙌
Feel free to:
- Open issues for questions/suggestions.
- Submit PRs to correct mistakes or add insights.
- Star the repo if you find it useful! ⭐
