OOO --- DEF CON CTF

 

 

We launched a playable archive of our past challenges!

archive.ooo

Isn’t it wasteful that challenges get lost after each game? In these crazy times we wanted some preservation, and to create a way to play and practice with ease for everyhacker.

We even started providing hints and videos for some of our old challenges, and we accept suggestions for them too. The archive is in beta, it offers most OOO challenges but not all of them.
