Fluid Attacks CTF - LATAM Challenge 2026-2First place overall. 22 challenges solved out of 22.

1st place overall 22/22 solved 21 published writeups

I finished first overall and solved every challenge in the event.

This is my public archive for the competition. The challenge list follows the official scoreboard order. Sanity Check is recorded as solved, but I did not publish a separate writeup for it because it was not a technical challenge.

The writeups are in English because they were originally prepared for the Fluid Attacks review process.

The GitHub archive keeps the same READMEs together with the scripts, generated artifacts and evidence files used during the solves.
