A brief overview of OpSec techniques for various threat levels. The talk will cover different techniques depending on what your threat model is. Are you trying to hide from your parents / spouse, your ISP, or nation-state backed threat actors? The talk will briefly cover alias and persona creation and compartmentalization, browser fingerprinting, VPNs and various ways they will fail you. Of course, we can't have a good OpSec talk with looking at and learning from some other people's glorious OpSec failures.
