I work in application security focusing on web application penetration testing and security research.
To me, ethical hacking is exploring everything we can make technology do. When this exploration intersects with a security impact, I believe in clear communication, responsible disclosure, and effecting positive change in the world.
The goal of this site is to share my experiences and methods in security research, including how I arrive at findings and break down vulnerabilities. I aim to present technical content in an approachable way.
I hope you enjoy.
