mkCTF is a framework designed to help teams create jeopardy-style Capture The Flag (CTF) challenges using a configurable structure. The framework enables efficient integration and deployment of challenges on CTF infrastructure. Originally developed for managing challenges for INS'hAck 2017, the project has evolved to provide automation capabilities for deploying challenges on Rancher-based infrastructure. The framework stores flags in plaintext to allow CTF administrators to rebuild challenges from sources without generating new flags. The tool requires Python 3.9+ and has been designed and tested specifically on Linux systems, though it may work on Darwin and Windows Subsystem for Linux. Additional dependencies vary based on the specific challenges being created. Security considerations include keeping the mkCTF repository private until the CTF event concludes, enabling two-factor authentication, and carefully managing access tokens and repository permissions to prevent unauthorized access to challenge materials and flags.
