What is the Google CTF?

Google will run the 2021 CTF competition in two parts: an online jeopardy-CTF
competition, and second contest open only to the top 16 teams. "Capture The
Flag" (CTF) competitions are not related to running outdoors or playing
first-person shooters. Instead, they consist of a set of computer security
puzzles (or challenges) involving reverse-engineering, memory corruption,
cryptography, web technologies, and more. When players solve them they get a
"flag," a secret string which can be exchanged for points. The more points a
team earns, the higher up it moves in rank.

What is the prize?

The top 3 teams from the jeopardy CTF will earn prizes of 13k, 7k, or 3k USD;
and the top 16 teams will be invited to another contest to compete for
additional prizes. In addition to these prizes, the best write-ups for
qualifying round tasks will receive prizes (beginners quest is not included).

How does it work?

If this is your first time playing a CTF, take a look at this video, and this
guide. In summary, we will release several challenges during the CTF, and each
challenge has a secret value (a "flag") with the format
CTF{some-secret-value-here}. If you find the flag, you can submit it for points.

When does the Beginner's Quest start?

The Beginner's Quest will be launched on August 28th at 00:00:00 UTC. Keep your
eye on the Beginner's Quest page.

Where can I submit a write-up?

Please submit all write-ups as an attachment in CommonMark Markdown format or as
a link to a GitHub gist to google-ctf-writeups@google.com. If your write-up
can't be submitted in Markdown (for example, if it's a video, or an app), please
send us a link to a ZIP file we can use to download it. The deadline for
submitting write-ups will be August 2 2021. If we extend the deadline, this will
be announced here.

Where can I ask a question?

You can reach us by email at google-ctf@google.com or join the Discord.
