Capture the Flag Overview

Test your skills with a capture the flag (CTF) hacking competition created specifically for SnowFROC by members of the Boulder OWASP chapter.

Competitors will be provided a series of web applications containing a variety of vulnerabilities. Each discovered vulnerability will earn points. The harder the hack, the more points earned. At the end of the day, the team with the most points wins.


All conference attendees may participate in the CTF tournament for no additional cost. If you would prefer to attend the general conference proceedings, the competition will be made available to attendees after SnowFROC ends.


Contestants will be provided a virtual machine which will run locally on self-provided devices. This is a BYOD event and all contestants are responsible for providing their own machine. No "loaners" will be made available.

All contestant machines should have:

Acceptable behavior

Competitors are only permitted to attack targets running on their local systems. Network traffic will be monitored to ensure there will be:

  • No attacking the scoreboard. Misuse will result in punitive action.
  • No targeting the VM. Do not mount the VM and harvest flags from within.
  • No attacking other teams, whether through coercion, DoS, theft, sabotage, or other malicious activity.
  • No collusion. Work only within your own team.


Small prizes will be awarded to winners. Anyone who worked on the project or who has access to project-related repositories is ineligible to win prizes.

Both team and individual prizes will be awarded based on merit and other achievements.
