DEF CON 2025

In the ever-expanding universe of DEF CON competitions, there are many winners. We salute them all. Some of these victories are so impressive that we recognize them with an extra awesome badge and free DEF CON entry for life. This badge is the Black Badge, and we list the winners on the Black Badge Hall of Fame.

We’ve updated the Black Badge Hall of Fame to include winners from DEF CON 24. You should check it out.
