$ What is DEF CON?
DEF CON is one of the world's largest and most notable hacker conventions, held annually in Las Vegas since 1993. It brings together security researchers, hackers, government officials, makers, and curious minds to share knowledge, compete, build, and challenge assumptions.
DEF CON Groups take that energy back home. Local groups are independently organized, but they share a commitment to curiosity, community, and responsible exploration.
