Free CTF Training

Whether you are leading a classroom or studying solo, these Docker-based challenges provide a streamlined way to engage with real-world exploitation.

For Mentors & Educators

Instantly spin up a lab environment without the headache. Pair these containers with a scoreboard to host competitive, engaging CTFs for your students in minutes.

For Independent Learners

Level up your skill set from home for free. Every challenge includes step-by-step guides designed to take you from initial access to full exploitation.

Easy Setup

If you can run sudo apt install docker.io on an x86_64 Ubuntu VM, you’re ready to go.

Solution Guide Note

My solution guides frequently use the placeholder IP address 172.25.200.200. When following along, simply swap this out with the actual IP address of the machine you are running the Docker container on. (Kali Linux and/or Ubuntu work great as Docker hosts.)
