OT Under Siege: How to Defend Critical Infrastructure From Nation-State Cyber Threats

Global conflicts are no longer confined to physical battlefields - they’re spilling into cyberspace.

In this urgent episode of Protect It All, host Aaron Crow breaks down the rising wave of cyber threats targeting critical infrastructure, from energy and water utilities to manufacturing and transportation systems.

Drawing on recent global events and real-world incidents, Aaron explores how nation-state actors, hacktivists, and advanced adversaries are increasingly targeting operational technology environments. These attacks often rely on “living off the land” techniques - leveraging existing tools and access inside networks rather than deploying obvious malware.

But this episode isn’t about panic. It’s about practical defense.

Aaron outlines the immediate steps OT security teams can take to strengthen resilience - even with limited resources and tight budgets.

In this episode, you’ll learn:

Why global instability increases cyber risk for critical infrastructure
How attackers exploit existing tools using living-off-the-land tactics
The importance of vigilance, monitoring, and patching in OT environments
Why access control and identity management are critical defenses
How organizations can improve security posture without massive investments
The role of collaboration and awareness in defending essential systems

Whether you operate power systems, water facilities, industrial plants, or transportation infrastructure, this episode provides real-world guidance to help you stay ahead of evolving threats.

Tune in to learn how OT teams can strengthen defenses and protect the systems society depends on - only on Protect It All.
