Are you seeking high-quality, Dockerized CTF challenges for cybersecurity training, competitions, or ethical hacking practice? I will create custom Capture The Flag (CTF) challenges with varying difficulty levels (Easy, Medium, Hard) to test and improve hacking skills!

Each challenge will be fully Dockerized, making it easy to deploy on CTFd, Hack The Box, or standalone servers. Whether you need a simple SQL Injection challenge or an advanced RCE with privilege escalation, I've got you covered!

What You'll Get:

A fully Dockerized CTF challenge (Easy, Medium, or Hard)

Custom vulnerabilities (SQLi, XSS, IDOR, RCE, Forensics, OSINT, etc.)

Real-world security flaws for an engaging experience

Write-up & walkthrough (for Medium & Hard levels)

Flag in CTF format (e.g., ctf{flag_here})

Automated deployment (Docker Compose)

️ Challenge Types:

Web Security: SQLi, XSS, IDOR, CORS Exploits

OSINT & Steganography: Hidden data in images, metadata, and files

Reverse Engineering: Crack binaries, analyze obfuscated code
