Rust & Ransomware: Defending Legacy OT Environments Against Modern Threats - Ueli

Decades-old machinery is colliding with modern cyber threats. Legacy Operational Technology (OT)—the systems that control our manufacturing plants, water treatment facilities, and energy grids—was engineered for 100% uptime, not for fending off ransomware. For years, these systems relied on the "air gap" for protection. Today, driven by the demand for real-time analytics and remote vendor access, that air gap is a myth. Connecting unpatchable, inherently trusting legacy systems to modern enterprise networks creates a massive vulnerability. Traditional IT security solutions like forced updates or aggressive network scanning can crash these delicate systems, leading to catastrophic physical downtime. In this 30-minute session, we will demystify the unique challenge of securing legacy OT environments without breaking them. We will explore how attackers navigate the ICS Cyber Kill Chain to pivot from IT networks into the physical plant, and outline practical, non-disruptive defense strategies.
