We've compiled and released all of the challenges from the last OpenCTF at DEF CON 27 in 2019! Check them all out here: github.com/Neg9/OpenCTF-2… - better late than never, right?
I'm disappointed. According to everybody I talked to, the Jail challenges did not accomplish their intended goal of making all participants love Perl. I really thought it would work! I guess we'll have to have more Perl challenges next year to try again.
Hope everybody enjoyed #OpenCTF at #DEFCON27! Now that the game's over, we'll be contacting the top three teams shortly about writeups and prizes, and working to open source challenges. So hang tight if you've got burning questions about how to solve the challenges! #TRYHARDER
#DEFCON27#OpenCTF! We will be at the contest & event closing ceremonies at 2pm at Paris in Track 4! We hope to see everyone who played there! #TRYHARDER
#OpenCTF Team to team firewall has been disabled. But you've got your hosts firewalled already, right? 172.31.192.0/18. This is a routed extension of the entire DEFCON network, in case you didn't realize that ;)
#OpenCTF will end tonight at 7PM (and there will be no OpenCTF tomorrow). >7PM, we'll have a debriefing session where interested players can ask questions of the organizers. You have just under 1.5 hours to pwn your services, find your flags, and get your points. #TRYHARDER!
#OpenCTF Wave 3 is now OPEN! All challenges are ready for you to HACK at #DEFCON27!
