DEF CON 34’s theme is ‘Agency’. We’re focusing on self-determination in our use of tech. Charting our own course and helping others do the same.

Let’s start moving our valuable attention to tech that supports our agency. Let’s find the places we can help and choose to act.

Visual style guide and homework assignments coming soon!
