This infographic outlines four steps for improving electric-sector cyber defense: identify intelligence-driven threat scenarios, deploy critical controls, prioritize high-risk industrial sites, and align cybersecurity investments with known adversary activity. The featured FrostyGoop scenario shows attackers exploiting an internet-facing router, deploying a webshell, and issuing unauthorized Modbus TCP commands that manipulated controller values and disrupted heating for approximately 100,000 Ukrainian customers for two days. The recommended SANS 5 Critical Controls emphasize OT-specific incident response, defensible network architecture, protocol-aware monitoring, secure remote access, and risk-based vulnerability management. Additional VOLTZITE, KAMACITE, and ELECTRUM scenarios illustrat
