DEF CON is one of the largest and most influential hacker conventions in the world, taking place at the Las Vegas Convention Center. The event brings together security researchers, hackers, students, journalists, federal employees, and technology enthusiasts for a hands-on celebration of cybersecurity, hacking culture, and digital exploration. DEF CON is known for its talks on the latest vulnerabilities, exploits, and defensive research, as well as its many Villages, immersive areas dedicated to topics like car hacking, lock picking, voting machines, aerospace, social engineering, and AI. Attendees can participate in capture-the-flag competitions, contests, workshops, and demonstrations that test and sharpen technical skills. The community-driven, irreverent atmosphere sets it apart from more corporate conferences while still delivering serious, cutting-edge content. Held immediately after Black Hat, DEF CON caps off a major security week in Las Vegas, drawing a global audience to a venue with the scale to host its sprawling villages, talks, and contests.
