Learn about operational technology (OT) cybersecurity through a detailed simulation of a cyber attack on a chemical plant in this 46-minute conference talk from BSides Edmonton 2025. Explore how OT systems that control physical processes in critical infrastructure and industrial environments become vulnerable as they increasingly connect to IT networks and remote access platforms. Discover the sophisticated cyber threats targeting industrial control systems and examine real-world attack scenarios designed to test current defense capabilities. Understand how organizations can better detect, respond to, and recover from cyber intrusions in industrial environments. Gain insights into the security challenges facing critical infrastructure as presenters Prashant Prashant and Rajat Kundu demonstrate attack methodologies and defensive strategies through practical simulation exercises.
