Hi, I'm Zaki Zarkasih 👋

I’m a Cybersecurity Practitioner and Security Researcher focused on Vulnerability Research, Bug Bounty, CTFs, and Defensive Security Engineering. I enjoy tracing a flaw from its root cause to its real-world impact, then documenting what happened, why it happened, and how it can be fixed.

This site is a collection of that work. Research, findings, projects, background, and ways to reach me.

No trackers. No unnecessary dependencies. Just a few static pages documenting the things I build, break, and learn.
