Join EFF at DEF CON 27! We're excited to be back for another DEF CON with a membership booth in the Vendor area, a contest, and talks.

Join the Cause

Come find us in the Vendor area talk to us about the latest in online rights, get on our action alert list, or donate to become an EFF member. We'll also have our limited-edition DEF CON 27 shirts available! These shirts have a puzzle incorporated into the design. Try your hand at cracking it!

Check back later for information on EFF staff's talks, workshops, and other events at DEF CON.

Tech Trivia Contest

Join us for some tech trivia! EFF's team of technology experts have crafted challenging trivia about the fascinating, obscure, and trivial aspects of digital security, online rights, and Internet culture. Competing teams will plumb the unfathomable depths of their knowledge, but only the champion hive mind will claim the First Place Tech Trivia Cup and EFF swag pack. The second and third place teams will also win great EFF gear.

Looking for Help?

As in past years, EFF staff attorneys will be present to help support the community. If you have legal concerns regarding an upcoming talk or sensitive infosec research that you are conducting at any time, please email info@eff.org. Outline the basic issues and we will do our best to connect you with the resources you need.
