In this episode of Protect It All, host Aaron Crow welcomes back Lesley Carhart for a fascinating conversation about why decades-old malware like Conficker continues to infect operational technology (OT) environments around the world. Drawing on nearly two decades of industrial incident response experience, they share real-world stories from the front lines of critical infrastructure, explaining why legacy systems, operational constraints, and workforce shortages continue to make remediation incredibly challenging. The discussion goes far beyond "just patch it," exploring the difficult risk decisions organizations face when uptime, safety, and cybersecurity all compete for priority. Aaron and Lesley also examine one of the industry's most pressing issues: the growing shortage of OT cybersecurity talent and the need to rebuild foundational technical skills for the next generation of defenders.  Key Learnings:  Why malware like Conficker still exists in modern OT environments The unique challenges of removing malware from industrial control systems Why patching isn't always possible in operational technology How legacy infrastructure creates long-term cybersecurity risk The growing OT cybersecurity skills gap - and how the industry can address it Practical lessons from real-world industrial incident response Key Moments:  05:47 Challenges with Old Industrial Systems 06:58 Struggles with malware cleanup 11:02 Challenges in Cyber Security Careers 16:19 Dealing with malware spread 17:53 Managing infection risk long-term 23:04 Challenges with nuclear hardware upgrades 27:05 Training the Next Tech Generation 29:33 Importance of Computer Basics 34:04 Discovering hidden technical issues 37:01 Troubleshooting in industrial environments 39:10 Malware and botnets era 42:20 Developing low-touch security solutions Whether you're responsible for manufacturing, utilities, energy, transportation, or any critical infrastructure environment, this episode provides practical insight into one of OT cybersecurity's longest-running challenges. Tune in to discover why yesterday's malware is still creating today's biggest industrial cybersecurity problems - and what organizations can do about it.
