About pwn.college
pwn.college is an online education platform called the dojo, where learners develop and practice core cybersecurity skills through hands-on work. The platform is maintained by a team at Arizona State University and is used in part of the university's cybersecurity curriculum. The homepage states that it is open to participation for free for interested people around the world.
Learners start at a white belt and work through a suggested ordered path of dojos and modules. The homepage says advanced stages, such as brown and black belt, happen outside the platform. The challenges are used to grade university students, so the site asks users not to publish writeups, walkthrough videos, or livestreams of challenge solutions.
