CTFsubmitter
→ View on GitHubCTFsubmitter is a centralized flag submission service designed for use in Capture The Flag (CTF) competitions, which filters and manages flag submissions to prevent flooding with invalid entries. It features a REST API for submitting flags, stores submission statistics in a MongoDB database, and requires both a submitter and a worker instance for functionality. The tool operates using bottle.py and cherrypy, with an additional stats service built on tornado, allowing for real-time monitoring and management of flag submissions.
