# Elastic Capture the Flag - ASEAN - Jan 2022

This CTF was a 1 hour compeition, and there was an Introduction to Elastic Security before the competition started. I did not manage to catch the intro as I was busy, but it would have been great if I could listen and follow the presentation. There were 30 challenges in total hosted on CTFD platform. You could only proceed to the next stage by solving the given challenge ie. no skipping of challenges.
