There was so much guess… so much guess that I gave up and only did the Digital Forensics category and some of the other Forensics which were copied challenges from other CTFs.

I only solved a few challenges this CTF as I didn’t have time to play, and this was the most interesting non-guessy one.

I played with CTF.SG last weekend and we achieved 10th in the rankings although we didn’t even solve a single pwn!

I played with CTF.SG and solved all the OSINT challenges in the Misc category!

This is just some sample code for when creating an XHR CSRF PoC. It is used for my self learning purposes and work sometimes.

I was trying to break out of a python sandbox back in October, when I discovered a By-Design bug.
