AI, Critical Infrastructure, and Cascading Failures with Madison Horn

Madison Horn joins host Frank Cilluffo to explain why AI-driven cyber risk may be quieter, faster, and harder to spot in 2026. She breaks down "cascading failures" in critical infrastructure—and how a disruption in one sector can quickly ripple into others. The conversation zeroes in on AI agents, especially their ability to create new user accounts, get access to systems, and hide inside everyday routine activity. Horn also warns that AI supply chain weaknesses could spread faster than traditional zero-days.   Main Topics Covered  Why AI-enabled attacks may look like normal business activity.  Cascading failures across water, power, telecom, and healthcare systems.  AI agents creating identities and operating with "human-like" access.  Why "AI supply chain" risk could eclipse zero-day exploits.  "Slow and steady" AI adoption for critical infrastructure operators.  Why quantum planning should happen alongside today's AI rollouts.   Key Quotes "Within critical infrastructure… water needs electricity, electricity needs telcos, and healthcare needs all three." —Madison Horn "Hackers are lazy. And I mean that not to be offensive, but if you can reach your objective, reaching the lowest hanging fruit, then you're going to." —Madison Horn "Attacks are not going to look as restricting and as loud. I think it's going to look just like business as normal until we see [impacts] in the physical world." — Madison Horn "What I worry about is people assuming and trusting that an AI tool is doing what it's supposed to and not necessarily understanding or being able to detect that it's doing something malicious." — Madison Horn "I just don't want quantum to get lost into the AI conversation." — Madison Horn Relevant Links and Resources Madison Horn's 2026 predictions (Nextgov) About the Guest  Madison Horn is the national security and critical infrastructure chief advisor at World Wide Technology, with 15+ years leading cyber strategy and incident response in high-consequence, regulated environments.
