Been waiting for the Linux version of Metasploitable3 to drop? We’ll do you one better: Metasploit is giving the community a week to rain shells on a penguin-shaped Metasploitable3 instance—and to win prizes at the end of it. Play starts December 4; see below for full competition details.

TL;DR: Sign up, drop shells, win stuff.

Not into capturing flags but jonesing for a look at the code? We’ll release the Linux Metasploitable3 source code to the community soon after the competition ends. Happy hacking!

Metasploitable3 Capture the Flag: Official Rules

No purchase is necessary to participate. Only the first 500 registrants will be able to participate.

To enter

  1. Create an account here.
  2. Use the instructions on the Control Panel to connect to the Kali Linux jump box. From there, attack the vulnerable Metasploitable3 box to find flags.
  3. When a flag is found, submit the MD5 hash to the Challenges section on the scoreboard. If it’s correct, points will be awarded! There are 14 flags total.

The participants with the three highest scores will win prizes. We’ll announce the winners in an official blog post shortly after the contest ends.

The leaderboard competition will open on Monday, December 4, 2017 at 12:00 PM (noon) EST and close on Monday, December 11, 2017 at 11:59 AM EST. The three (3) participants with the highest point total at the end of the competition will receive the prizes listed below. In the event of a tie, the participant who reached that score first will be the winner.

You may participate as an individual or as a team. However, only ONE prize can be awarded for each winning account; therefore, if you are participating as a team, please be aware that we cannot offer prizes to each team member. (Any further method used to determine who among your teammates takes home the CTF spoils is up to you. We hear thumb wars and structured rock/paper/scissors competitions are effective.)
