Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill downloads the ttyd binary from its official GitHub repository (tsl0922/ttyd) during the Docker image build process for certain challenge profiles. GitHub is a well-known and trusted service.
  • [COMMAND_EXECUTION]: Several Python scripts (render_component.py, render_scenario.py, validate_scenario.py) use the subprocess module to execute other scripts within the same skill package. This is standard behavior for orchestrating the build and validation workflow.
  • [INDIRECT_PROMPT_INJECTION]: The skill processes user-provided CTF challenge directories and configuration files (challenge.yaml). While this presents a theoretical attack surface, the skill implements strict validation rules (validate.sh) and uses safe interpolation methods (e.g., shlex.quote) when generating scripts.
  • [SAFE]: Heuristic detections for reverse shells were triggered by legitimate health check commands using the /dev/tcp device in Bash (e.g., bash -lc 'echo > /dev/tcp/127.0.0.1/80'). These are standard diagnostic commands in containerized environments and do not represent a threat.
