CubeCTF 2025

weight 24.71 CTFtime official repo

CubeCTF is coming back this year with Attack/Defense! Game format will follow traditional FAUST-style A/D format, with infrastructure provided by glitchrange.com.

Brush up on your vim shortcuts and tcpdump flags - the environment will be hosted in an isolated environment with only web console access and no direct internet connection to vulnboxes, so AI agents will not have access.

If you've been looking to bring the humanity back into CTFs, so have we - come play head-to-head with a range of challenge difficulties designed for everyone.

Full infrastructure documentation, rules, and registration information will be published via Discord.
