Who we are
About Null Authority
CTF team. We break things to understand them.
Null Authority is a cybersecurity competition team. We compete in CTFs across the world — jeopardy, attack–defense, and everything in between — covering web exploitation, cryptography, binary exploitation, reverse engineering, forensics, and OSINT.
The name is the mission: null assumptions, authority earned through results. Every challenge we break becomes a published writeup; every competition becomes a tracked result; every internal tool eventually ships as open source.

How we work
Document everything
A solve isn't finished until it's written up. Our archive is the team's institutional memory — every exploit path, every dead end that mattered.
Compete seriously
We show up to win. Rankings are tracked, results are public, and every event gets a retrospective before the next one starts.
Build in the open
The tooling we write for competitions gets hardened and released. If it helped us, it should help everyone.
