10:00 - 11:45 August 10, 2025

AppSec Village is proud to present our DEF CON Contest in partnership with SecDim. Unlike a typical CTF, this contest rewards the players who fix security vulnerabilities. You can choose between secure coding challenges or competing against other players in an Attack & Defence AppSec challenge, where you need to secure your app before being given a chance to hack other players’ apps😈. You can also develop your own AppSec challenge by following the challenge contribution guidelines. All approved challenges will be hosted during AppSec Village @ DEF CON.

There are two categories of winners:

  • The player with the highest total points by the end of the event (August 10 at noon PDT)
  • The best-contributed challenge submission

The Award Ceremony will be held at 12:45 PM PDT in the AppSec Village on August 10.
