Grid Under Glass: The ICS Kill Chain from Breakers to Bytes

Cyber-physical power systems are increasingly vulnerable to attacks that blur the line between bits and breakers. This blog post explores how adversaries methodically move from network infiltration to catastrophic grid disruption—focusing not on abstract malware, but on the very real-world hardware where incident response must span linemen and laptops. Using recent research and the Security Nexus Deep Dive transcript, we break down the evolving kill chain, the point of no return (PNR), and how relays, substations, and the trust we place in them may be the last line of defense.
