Grey Cat The Flag Qualifiers 2022 Writeups

rainbowpigeon.helge[AT]8alias.com (rainbowpigeon) — Sun, 12 Jun 2022 13:42:06 +0800

We got 4th overall and also qualified for the finals as the 3rd verified local team! My teammates were absolute beasts even though they were quite busy :) Challenge names with 🍭 are supposed to be “easier” while those with 🩸 come with first blood prizes (I managed to get 2!).

CTF.SG CTF 2022 Writeups

rainbowpigeon.helge[AT]8alias.com (rainbowpigeon) — Mon, 14 Mar 2022 00:16:06 +0800

We got 3rd place which was quite an improvement from the result of our previous year’s participation! I also managed to get a First Blood for Wordle.
Anyway I apologize for my slight inactivity at the start of the year — I was quite busy so I didn’t participate in any CTFs or events to write about.

HTX Investigators' Challenge 2021 Writeups

I’m really proud of my team for topping the scoreboard!
This CTF was done through a 3D Unity game where there are 3 locations for you to explore and find challenges in. There were hiccups with some challenges but generally it was still fine. It would have also been nice if the in-game description texts for challenges were made selectable so that we could copy-and-paste them elsewhere for convenience and organization.

TISC 2021 Writeups

I could have been 5th place but unfortunately I did not officially qualify to be a real participant in this event. Still had a good time though, notwithstanding the fact that there was so much ‘steganography’ and quite a bit of guesswork at certain points :)

Malwarebytes CrackMe 3 2021 Solution

rainbowpigeon.helge[AT]8alias.com (rainbowpigeon) — Sat, 20 Nov 2021 09:51:06 +0800

This CrackMe was a pleasure to complete! It was decently difficult for my level and I definitely learnt a lot. I was the 6th to submit, though I could have probably been faster if the release aligned with my timezone and I didn’t spend that much time outside 😄. Nevertheless, I won the main prize for the writeup contest!
Much appreciation to hasherezade for designing this CrackMe as well as releasing all her amazing tools that aid analysis.

Kinda disappointed I wasn’t able to do any Web ones (that weren’t solved already), but it’s alright. We got 7th place across all teams despite only having 4 members participating in this :)
