Free, self-hosted lab
Escape the Labyrinth.
Knossos is a complete penetration testing lab you run on your own machine. One command brings up a full vulnerable target network with 33 flags to capture. No signup, no cloud, no cost.
git clone https://github.com/pentest-tv/knossos.git && cd knossos
docker compose up -d --buildThen open the scoreboard at http://localhost:8890 and your Kali attacker box at http://localhost:7681. Needs Docker and about 2.5 GB of free RAM.
A network, not a single box
Active Directory, web apps, services and pivots across multiple hosts, wired together the way a real engagement looks.
33 flags, one Labyrinth
Capture every flag to clear the lab. A local scoreboard tracks your progress and links straight to each target.
