History

The official DC415 was inactive, but there is now a group of people that call themselves DC415 who is currently active. This page represents the currently active DC415.

At DC33, a group of hackers started communicating to unofficially restart the DC415 group. During the 2025/08 21 Five Minutes of Fame, a group of people from this group cemented having meetings at Noisebridge to revive DC415.

The first informal meeting was at the 30th Anniversary of the Hackers film hosted at DNA lounge's Cyberdelia event. The first official meeting of the group after restart was on October 14, 2025 in the electronics room at 7pm.

Shortly before DEF CON 34, DC415 received a new official DEF CON Groups designation. We are officially your local outpost for keeping the DEF CON spirit alive all year long.
