DEFCON began in 1993 as an "orgy of information exchange, viewpoints, speeches, education, enlightenment...and most of all sheer, unchecked PARTYING."(DEFCON 1 Announcement, 1993). Fourteen years later, the convention is one of the most established hacker conventions, and is defined as "the largest underground hacking convention in the world." However, significant social and technological changes have occurred during this period. The growth of the Internet, the increased need for computer security and the increasing significance of computer crime may have critically affected the shape and scope of the convention over time. This talk will critically examine the DEFCON convention over the past 14 years to understand the ways the con has changed, using previous convention materials, including programs, panels, and websites. The content, nature, and scope of the convention will be considered, including the number and types of presentations, as well as the presenters' credentials. This information will be assessed to consider what this says about the nature of the convention and the underground after 14 years. Audience participation is welcomed to inform this discussion and provide first hand insight into the past, present, and future of DEFCON.
