About the CTF

The BSides Limburg CTF 2026 was a student-built Capture The Flag competition created for BSides Limburg.

With the Friday the 13th theme, participants explored web security, cryptography, forensics, reverse engineering, hardware, OSINT and more.

The competition ran on CTFd with a custom theme. Individual challenge environments could be provided where required, running on self-hosted Kubernetes infrastructure.

The event infrastructure no longer exists. This site now serves as a static historical record of the competition.

Infrastructure

The platform was built and operated on self-hosted infrastructure using a combination of Proxmox, Kubernetes and dedicated hardware.
