👋 Assalamualaikum, I'm Zahidul Islam Ratul

Ethical Hacking Python JavaScript Bash Kali Linux TryHackMe Hack The Box

Welcome to my GitHub profile! I am an ethical hacker offering professional penetration testing services.

🚀 About Me

I am a passionate ethical hacker and penetration tester committed to offensive cybersecurity, Defensive security, and vulnerability research. My mission is to fortify digital defenses by thinking like an attacker — responsibly and legally.

With hands-on experience in both manual and automated security assessments, I identify and analyze system vulnerabilities to help organizations proactively address threats before they can be exploited. I actively sharpen my skills on platforms like TryHackMe and Hack The Box, while developing custom scripts and payloads to improve testing efficiency.

This repository is a curated collection of my tools, notes, and research, designed to contribute to the infosec community and fuel continuous learning.
