The first CTF hosted by the team PeanutButter.jar!

After participating in many CTFs and figuring out what we do and don't like, we hope to bring a high quality CTF with interesting problems. The CTF will contain standard categories: pwn, rev, crypto, web, forensics, misc. There will be a team limit 5 people per team.

We will have some challenges for beginners, even if you're brand new, but we also plan on having a variety of challenges problems for more advanced participants, so we hope it is appealing for everyone! Also, please tell others about our CTF. :pray:

Also for some reason CTFtime shows it as 5AM EST, but the time is 10AM EST.


Prizes will be for separate high school and open division. Each division will get some amount of prizes for the top 3 places.

Also, we have a referral leaderboard with small prizes in hopes of spreading the word about our CTF. :)
