    The Grid, a Digital Frontier: E-ISAC on Securing the Power Grid
    Dec 3 2025
    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across utilities What motivates hacktivist groups and how their tactics differ from other threat actors Why outdated equipment and legacy systems remain such attractive targets Some questions we ask: Are you seeing more educated and capable OT-focused adversaries now?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?

  • The New Frontlines of Cybersecurity: Lessons from the 2025 Digital Defense Report

    The New Frontlines of Cybersecurity: Lessons from the 2025 Digital Defense Report
    Oct 22 2025
    In this episode of the Microsoft Threat Intelligence Podcast, host Sherrod DeGrippo is joined by Chloé Messdaghi and Crane Hassold to unpack the key findings of the 2025 Microsoft Digital Defense Report; a comprehensive look at how the cyber threat landscape is accelerating through AI, automation, and industrialized criminal networks. They explore how nation-state operations and cybercrime have fused into a continuous cycle of attack and adaptation, with actors sharing tooling, infrastructure, and even business models. The conversation also examines AI’s growing impact, from deepfakes and influence operations to the defensive promise of AI-powered detection, and how identity compromise has become the front door to most intrusions, accounting for over 99% of observed attacks. Listeners will gain perspective on: How AI is shaping both attacker tradecraft and defensive response. Why identity remains the cornerstone of global cyber risk. What Microsoft’s telemetry—spanning 600 million daily attacks—reveals about emerging threats and evolving defender strategies. Questions explored: How are threat actors using AI to scale deception and influence operations? What does industrialized cybercrime mean for organizations trying to defend at scale? How can defenders harness AI responsibly without overreliance or exposure?
