The threat hunting practice has helped security teams detect and reduce dwell time of stealth threats. But most hunting expeditions focus on threats - leaving the adversary free to launch another set of attacks with different tactics. We need to evolve threat hunting into a hunt for the adversary.

Over the course of this session, we will understand the motivation behind the actions of these actors, their social networks, and how to anticipate their next steps.
