DEFCON 33: Retrospective

1 CTF. 2 full days of hacking. 3 teams. 4 victories. When we won last year, our hat-trick, we were the first in DEF CON’S history to do it. 3 consecutive victories, 8x3 (24) black badges awarded in 3 total years. I think it was safe to say that a reputation formed around us and naturally, speculation. PPP and The Duck already had their own reputations so it’s not like the secrets and rumors and awe towards MMM came out of nowhere. However, it’s not like MMM was the only team that did well enough to have a reputation in the CTF community. ...

DEF CON 32 Retrospective, end of the year recap

In 2009, a group students at the Carnegie Mellon University formed a computer security club known as the Plaid Parliament of Pwning, abbreviated to PPP, to participate in Capture the Flag contests. The team saw numerous successes throughout their tenure, and many of the CMU folks with their roots in PPP went on to succeed professionally in cybersecurity-related careers. 2 such members went on to co-create Theori.io, a leading platform of security solutions covering everything from security education to audits and consulting. Their presence exists in both South Korea and USA, and they have their own CTF team, The Duck, that dominates leaderboards whenever they play. ...

A case for documentation

I am aware that the main target audience of my tiny blog are CTF players looking for my writeups and other like-minded security researchers exploring topics I like. But my 2024 resolution was to relive and unite my artistic persona that I spent most of my teen years curating, and marrying that to the security career life I live now. Part of my fine arts training involved a good deal of literature. I wanted to write some random stuff really badly, and this post came out of that desire, I understand it’s out of left field especially given the content of my other work here. If people like this I’d be happy to intersperse more of this into my usual stuff of writeups and security research. ...

DEFCON 31: Retrospective

Beginning Back in October of 2019, I was attending my 3rd/4th? year at UBC, where I tried to play in a beginner-friendly CTF known as “CSAW 2019” with UBC’s team: Maple Bacon. Particularly, I tried out a challenge called Unagi, which, having spent an eternity on, I managed to solve after hours of wrangling with the problem. To be completely frank, I solved the challenge after googling “XML vulnerability” and trying out payloads - really, just, throwing payloads and modifying them to tailor the challenge - until one stuck and I got the flag. I was happy, but I also thought, “what the hell did I achieve? what did the payload do? What did I learn?” and I couldn’t come up with an answer I was satisfied with. I really just googled information about XML vulenrabilities, found an XXE payload, and threw it hoping to see if something would change (I didn’t even know what XXE stood for). Granted, I still needed to modify the payload. Unagi required more effort than just a copy-paste. But overall, my first experience was largely juvenile and I was still as naive as I was pre CSAW 2019. ...

DEFCON 30: Retrospective

Man. My team, Maple Bacon, collaborated with CMU’s CTF team PPP and Theori.io’s CTF team The Duck, forming Maple Mallard Magistrates as a merger to participate in DEF CON finals. The Beginning Discussions about the merge had occurred earlier in the year - I triangulate it to a month or so before I found myself in Athens, Greece attending ICC. This is important to mention as I heard many people speculate about the existence of MMM and whether or not it was formed as a response to something. The answer is no, the reasoning was very simple: we wanted to play together! Unfortunately, there wasn’t much of a complex reason, we simply had a desire to team up and have fun in Vegas. ...

MapleCTF UBC ver. Retrospective

Jan 21-28 marked the inaugural MapleCTF: UBC version, Maple Bacon’s first CTF to hit the scene. For our very first, we wanted to keep it local. This made it very different from most other CTFs that one would be used to. We treated this as a beginner event - hoping to introduce the UBC community to the concept, well aware that we would have to cater to varying skill levels. ...
