In this session, Alessandro Agnello, a cybersecurity specialist with a background in the U.S. Air Force and medtech, delivers a candid and at times alarming look at the vulnerabilities within building management systems (BMS). He outlines how legacy systems, always-on connectivity, weak passwords and poor network segmentation create an easy entry point for attackers. Through real-world examples — including major breaches and attempted attacks on healthcare facilities — he demonstrates how cyber incidents can quickly escalate from digital intrusions to real operational and safety risks, from HVAC disruptions to compromised medical systems.
