- Handy Tools
- pngcheck
- pngcheck verifies the integrity of PNG, JNG and MNG files (by checking the internal 32-bit CRCs [checksums] and decompressing the image data); it can optionally dump almost all of the chunk-level information in the image in human-readable form. For example, it can be used to print the basic statistics about an image (dimensions, bit depth, etc.); to list the color and transparency info in its palette (assuming it has one); or to extract the embedded text annotations. This is a command-line program with batch capabilities.

- hack-the-arch
- This is a scoring server built using Ruby on Rails by the Military Cyber Professionals Association (MCPA). It is free to use and extend under the MIT license (see LICENSE file). The goal of this project is to provide a standard generic scoring server that provides an easy way to add and modify problems and track statistics of a Cyber Capture the Flag event. While it's not recommended, this server can be hosted with your challenges but we do recommend sand-boxing your challenges so they do not affect the scoring server.
- iCTF Framwork
- This is the framework that the UC Santa Barbara Seclab uses to host the iCTF, and that can be used to create your own CTFs at http://ictf.cs.ucsb.edu/framework. The framework creates several VMs: one for the organizers and one for every team.

- picoCTF-Platform-2
- The picoCTF Platform 2 is the infrastructure on which picoCTF runs. The platform is designed to be easily adapted to other CTF or programming competitions. picoCTF Platform 2 targets Ubuntu 14.04 LTS but should work on just about any "standard" Linux distribution. It would probably even work on Windows. MongoDB must be installed; all default configurations should work.
- py_chall_factory
- Small framework to create/manage/package jeopardy CTF challenges
- Root the Box
- Root the Box is a real-time scoring engine for a computer wargames where hackers can practice and learn. The application can be easily modified for any hacker CTF game. Root the Box attempts to engage novice and experienced hackers alike by combining a fun game-like environment, with realistic challenges that convey knowledge applicable to real-world penetration testing. Just as in traditional CTF games, each team attacks targets of varying difficulty and sophistication, attempting to collect flags. However in Root the Box, teams can also create "Botnets" by uploading a small bot program to target machines. Teams are periodically rewarded with (in-game) money for each bot in their botnet; the larger the botnet the larger the reward.
