Abstract
This project investigates cascading risks in cyber-physical systems under climate uncertainty, focusing on how natural disasters and cyberattacks can compound to disrupt critical infrastructure. Modern infrastructure systems—including those dedicated to power, water, and telecommunications—depend on cyberspace for real-time monitoring, control, and coordination. Using FEMA’s Hazus software and the synthetic CLARC county dataset, we simulate storm events and assess their impact on these interdependent systems. Cyberattack scenarios are modeled using the MITRE ATT&CK framework, examining how the timing of attacks relative to natural disasters affects system vulnerabilities. Our findings aim to inform risk mitigation strategies that address both environmental and cyber threats in tandem.
