About

Hi there, I’m Kirolos a passionate cybersecurity enthusiast with a sharp focus on penetration testing. My strength lies in thinking like an attacker: exploring systems, identifying weaknesses, and staying ahead of threats before they become real. I’m actively building skills in web, network and Active Directory pentesting and I’m constantly learning to stay updated with the latest tools, exploits and real attack vectors. Whether it's a Capture the Flag challenge, a vulnerable lab, or a real assessment, I approach every task with curiosity, logic and a hacker mindset.
