Poland’s Power Grid Cyberattack What It Teaches Us About OT Security and Renewable Energy Risks

What happens when attackers target the systems that keep the lights on?

In this episode of Protect It All, host Aaron Crow breaks down the December 2025 cyberattack on Poland’s energy infrastructure, where coordinated attackers disrupted wind farms, solar installations, and heat and power plants - impacting nearly half a million people.

This real-world incident highlights the growing risks facing distributed energy resources (DER) and modern power grids. As energy systems become more connected and decentralized, the attack surface expands - often faster than security programs can adapt.

Aaron walks through what actually went wrong: default passwords, unpatched devices, and weak network segmentation that allowed attackers to brick OT equipment and blind operators to what was happening in their own systems.

You’ll learn:

How attackers targeted renewable energy infrastructure at scale
Why edge devices and distributed assets create new vulnerabilities
The importance of eliminating default credentials and poor configurations
Why network segmentation and secure remote access are essential
What grid operators and OT teams must prioritize immediately
How lessons from Poland apply to power grids worldwide

For engineers, operators, and cybersecurity leaders responsible for critical infrastructure, this episode delivers practical insights on defending modern energy systems before attackers strike again.
