Compete to win.
Learn from zero.
We train every week and compete at the highest level — Google CTF, PlaidCTF, and 8 others, with our solutions published for every one. Every domain gets worked hard, pwn through OSINT, and every skill level has a seat.

Building blocks of CTF
Each category demands a different set of skills, techniques, and ways of thinking.
- pwnBinary exploitation
- Feeding a program input it was never built to survive, until it hands you control.
- revReverse engineering
- Taking a compiled binary apart with no source code, until you understand what it does and why.
- webWeb exploitation
- Finding the one request a web app trusts that it shouldn't. The category most people start in.
- cryptoCryptography
- Breaking the maths, or more often, breaking the way someone used the maths.
- forensicsForensics
- Reconstructing what happened from a disk image, a packet capture, or a memory dump.
- osintOSINT
- Finding what is technically public and practically hidden. No tooling required to begin.
