DEF CON 25 Hacking Conference



The contests at DEF CON are community generated, and we want to thank all the people who give their time and energy to think them up and bring them to life. We're proud of how varied and challenging and creative the contest scene has become.

We also appreciate all of the contest participants who wade into the fray and get involved. That enthusiasm keeps us working to make every year better than the last.

And of course, congrats to the winners. These things can be pretty demanding of your brain and your energy and your sleep bank. Take a moment to bask in your glory, victors. You have done well.
