Security, gamified.

Attack-Defense CTFs are a highly rewarding way
to learn security concepts.

Learn faster by applying skills directly
in a fun, competitive setting.

Fail safely in a realistic virtual environment
when the stakes are low.

And, let's be real —
who doesn't want to know how to hack?

How it works.

Form Teams

Each team gets the same services
and a server to run them on.

Find Vulnerabilities

Analyze the deployment and find
vulnerabilities in each service.

Attack & Defend

Exploit your enemy team's services
while patching your own.

# general

Why it works.

Competition and team spirit fuel the drive
to win and learn.

Skills transfer well to development
and incident response.

Players learn first-hand what
mistakes lead to incidents.

The best defense is an attacker's mindset.

Hacking with Heart.

Attacking-Lab is a collaboration between players
from high-ranking CTF teams.

Hacking isn't just a game to us,
but we know how to make it fun.
