[DiceCTF 2022] - memory hole
Introduction
During this weekend, I casually played DiceCTF 2022 with my team Shellphish. And I solved two challenges: baby-rop
and memory hole
during the game.
It was the first time in a while that I played CTFs with OOO people: @Zardus and @adamd (internally, we call them OOOld people :) ). Initially, I didn’t plan to play the CTF because of my research work. But @adamd “bullied” me into it by saying “now get me the flag” when I casually posted some techniques that could help the team solve baby-rop
. So, I solved it.
After solving baby-rop
, I thought I was done with the CTF. But the next day, @adamd (yes, it was always him.) posted some info about memory hole
in our discord channel, I got immediately hooked up by the challenge: what’s more exicting than bypassing the latest defence in V8? Besides, I haven’t done any V8 challenge in a few months, it’s a good time to pick it up again. So, I decided to have a look at it and finally solved it with a different approach from intended solution.
