Hi 0x00’ers, and all those that took part in 0x00ctf 2017!
First off, we want to thank all of our challenge creators, admins, and participants. CTFs are a great opportunity for us as a community to sharpen our skills, challenge ourselves and each other with new problems, and meet new people who share our passion for information security. This event was a great success.
These creators are @_py, @0x00pf, @dtm, @oaktree, @exploit and @pry0cc (kinda)
As most of you know the first prize for this CTF was a Binary Ninja license donated to us by Binary Ninja, one of our Partners... But, before we announce the winner, here are a few preliminary stats.
The most-solved challenge was @oaktree’s C++ challenge-000 (guessme); the least-solved was @0x00pf’s challenge-009 (OBFS). The challenges will remain available after the contest.
