UIUCTF20 was a really fun Animal Crossing themed CTF that ran from July 17-19 2020. While I have not played the game before, I somewhat knew what it was about from watching Youtubers play it, and also from memes about the turnip stock market.

To celebrate the 10th anniversary of PPP, and the 9th ever PlaidCTF, we’re happy to announce a new official website and blog.

First, we would like to thank everyone for participating in PlaidCTF 2014. Thanks to all of you, this year was bigger than ever with over 850 teams partcipating and 3 sponsors (THANK YOU!) providing $14K in cash prizes and covering all of our operating costs. Congratulations go out to 0xffa, Dragon Sector, and MoreSmokedLeetChicken for finishing in 1st, 2nd, and 3rd. We hope everyone had a lot of fun with the challenges and maybe learned a thing or two, as well.

A recent blog post has been going around talking about the differences between competitions like CCDC (Collegiate Cyber Defense Competition) and CTFs (Capture the Flag). It’s a good read and I thought a lot of interesting points were brought up, and figured it could be beneficial to try to respond to them some place to encourage discussion (and besides, our blog needs any excuse it can get for new content). For what it’s worth, I didn’t watch Chris Eagle’s presentations, though I imagine I don’t agree with everything he said. Likewise, I don’t disagree with everything from Matt Weeks’ blog post. This post is mostly motivated by the fact that while a discussion on security competitions is going, it makes sense to talk about some related things I have been thinking about.

This is a write-up for 800 point pwnable challenge called “membership” from Codegate CTF 2014 Pre-qual round. PPP was the only solver for this challenge during the competition, so I have decided to do a write-up for the challenge. Enjoy.  (awesie and ricky solved it during the competition.)
