The Grid as a Cyber Battlefield

In this episode of the Microsoft Threat Intelligence Podcast, host⁠ ⁠⁠Sherrod DeGrippo is joined by Matt Duncan, Vice President of Security Operations and Intelligence at the North American Electric Reliability Corporation’s E-ISAC, to explore the cyber threats targeting the North American power grid. Matt breaks down why the grid remains resilient despite increasing pressure from nation-states, cybercriminals, and hacktivists, how AI is lowering the barrier of entry for attackers, and why OT systems and interconnected devices present unique risks.  

He also highlights real success stories, the value of large-scale grid exercises, and how strong collaboration and a focus on foundational security practices help defenders keep power flowing safely and reliably. 

In this episode you’ll learn:      

• How severe weather events trigger heightened cyber-readiness across utilities 

• What motivates hacktivist groups and how their tactics differ from other threat actors 

• Why outdated equipment and legacy systems remain such attractive targets 

Some questions we ask:     

• Are you seeing more educated and capable OT-focused adversaries now? 

• How do you work with policymakers to help them understand these threats? 

• If you could eliminate one misconception about securing the grid, what would it be?
