When AI Changes the Rules of Cybersecurity

Cyber risk is changing — and AI is accelerating it.

In this episode of the AI Proving Ground Podcast, former NSA Director Rob Joyce joins WWT’s Madison Horn to explain how nation-state cyber activity has shifted from quiet espionage to strategic pre-positioning inside critical infrastructure.

AI isn’t introducing new tactics — it’s collapsing timelines. Reconnaissance, phishing, and exploitation now move at machine speed, shrinking response windows from weeks to minutes. The result is a fundamentally different threat model.

The conversation focuses on what leaders need to understand now: how agentic AI reshapes cyber risk, why basic discipline still matters but no longer scales on its own, and how AI must become a force multiplier for defenders.

A clear, high-level look at the cyber line that’s already been crossed — and what comes next.
