This was our fourth year playing the cloud village CTF and it was as fun as always. One of the new things added this year was a dynamic point system. This means that the first team to solve a problem gets the full points, the second team gets slightly less, and so on. It allows for a more strategic approach where it can be worth having some teammates jump to higher point challenges that will take longer early on.

We placed 5th this year, closely behind 3rd/4th while the first place team absolutely dominated.

What is Cloud Village

(copy/pasta from 2022 writeups)

Cloud village is a village at Defcon self described as:

Cloud Village is an open space to meet folks interested in offensive and defensive aspects of cloud security.

Jeopordy style means the CTF solutions are submitted in standardized flags. For cloudvillage, the format was FLAG-{ANY_32_CHARS_HERE}; for example: FLAG-{abcdefghijklemnopqrstuvwxyz1234567890}
