Skill level
This event is designed for entry level through advanced cybersecurity professionals. The puzzles are in escalating difficulty.
Teams will consist of 1 - 10 people. Participants are welcome to form their own teams. The Cyber Fire team will open a public Mattermost channel (similar to Slack) for participants to coordinate their teams.
Participants will need a laptop, internet connection, and modern web browser (no older than Chrome 74, Firefox 66, Safari 12, or Edge 18). Participants will not be able to use Internet Explorer.


The competition will kick off at 08:30 US/Mountain, and end at 11:30 US/Mountain on the next day. Participants will be able to choose when they want to log onto the DOE Cyber Fire puzzle server and work on the puzzles, any time while the puzzle server is open.

The DOE Cyber Fire team will use Mattermost as the primary communication during the event. Each participant will be sent an invite to set up an account prior to the event. Participants will be able to form private channels in Mattermost with their team members to communicate and collaborate before, during, and after the event.

Puzzles will cover the following technical areas:

Most puzzles will focus on traditional IT networks, with some specialized puzzles focusing on operational technology (OT) and ICS systems.
