In this episode of Protect It All, host Aaron Crow welcomes Pedro Umbelino, Principal Research Scientist at BitSight, for an insightful and lively conversation recorded shortly after they met at RSA. Pedro shares stories of his early days in computing, from scavenging parts as a kid to teaching himself programming on a ZX Spectrum. The discussion quickly dives into critical cybersecurity issues across the interconnected worlds of IT and OT, focusing on dramatic vulnerabilities in Automatic Tank Gauges (ATGs) at gas stations—exposing ways attackers could cause significant physical damage and even spark major operational disruptions, all through insecure legacy protocols.
Pedro also brings attention to a ticking time bomb: the “Year 2038” problem, where millions (if not billions) of 32-bit systems might fail due to an epoch time rollover—an issue that could have consequences reminiscent of Y2K, but on a potentially broader scale, especially for OT and critical infrastructure.
Throughout the episode, Aaron and Pedro share practical strategies, lessons from the field, and the sobering reminder that many of these vulnerabilities are still lurking below the surface. The conversation highlights the importance of awareness, collaboration across industry and ISPs, and a proactive approach to understanding and hardening both new and legacy systems. Whether you're an OT engineer, a security researcher, or just curious about what it means to truly “protect it all,” this episode offers a fascinating look at the evolving landscape of digital and physical security risks.
