Saturday | Aug 9th 2025
Adversary Village workshop stage | Las Vegas Convention Center
Adversary Philosophy

Cyberjūtsu is a new way to teach cybersecurity inspired from martial arts trainings. It is an educational way which allows everyone (novice to expert) to practice together and improve themselves in cybersecurity through confrontation. It follows budō (judo, jujitsu, karate...) principles and ethical code. The goal is to reach "maximum-efficient use of computer" in a "mutual benefit" of a human confrontation. It's a digital martial art fight e-sport using linux shell.
