Build-A-CTF
Join us to create unique hacking CTF competitions meeting every Sunday at the HacDC Space. Sign up for events at Meetup.com.
As per Wikipedia, "A Capture the Flag (CTF) in computer security is an exercise in which "flags" are secretly hidden in purposefully-vulnerable programs or websites. It can either be for competitive or educational purposes. Competitors steal flags either from other competitors (attack/defense-style CTFs) or from the organizers (jeopardy-style challenges)."
Goals
Our first CTF aims to achieve the following goals:
- Be a learning experience, for both the organizers and participants
- Be beginner-friendly, open and accessible to first-time participants
- Be fun, engaging, and encouraging to newcomers to explore the wider world of cybersecurity
Design
Based on the above goals, we have decided to design our first competition in the style of [ https://en.wikipedia.org/wiki/King_of_the_hill_(game) King of the Hill] (KotH). A participant wins the event upon maintaining the sole login session on the target machine for 30 uninterrupted minutes. Participants may use any exploit to establish a session on the target machine, but are only allowed to patch the exploit that they used to enter upon establishing a session. It is in the interest of the present King to monitor the machine for sessions established by other teams, and to continue to research exploits in the event that they are dethroned by an opposing team.
Architecture
The environment will be developed in GNS3, a virtualization software that enables the CTF organizers to construct a purely software-based network, all within a single VM! VMs inside a VM, a.k.a. VM-ception.
