I’m Onyonka Maeri, an Offensive Security Researcher with a sharp focus on Penetration Testing, Exploit Development, and Reverse Engineering.

My work involves tactically breaking down complex systems to uncover vulnerabilities, developing targeted exploits, and reinforcing defenses against advanced threats.

I specialize in Windows Internals and advanced scripting to craft bespoke solutions that stay ahead of evolving attack vectors. Currently, at SCIAT AFRICA, I lead research efforts to enhance cybersecurity strategies and empower organizations to combat sophisticated cyber threats.
