AI-Generated Exploit Scripts Target Siemens S7 PLCs in U.S. Critical Infrastructure

U.S. agencies warn of an active AI-assisted campaign targeting Siemens S7-series PLCs and other ICS devices using AI-generated exploit scripts and internet scanning to find exposed, outdated controllers—posing disruption, safety, and data compromise risks to critical infrastructure. The report also describes a near-autonomous multi-agent AI intrusion (targeting Taiwan) that automated reconnaissance, credential cracking, vulnerability discovery, and large-scale data exfiltration, prompting recommendations to patch, isolate PLCs, enforce strong access controls, and monitor OT/ICS environments.
