U.S. agencies warn AI-powered attacks on Siemens PLCs at water plants

NSA, CISA, and federal agencies warned that threat actors deployed AI-generated exploits targeting Siemens S7 PLCs (S7-200 to S7-1500) across U.S. critical infrastructure using public scanning services and disguised as legitimate monitoring tools. AI-assisted exploitation lowers attacker skill requirements and accelerates development cycles, forcing infrastructure operators to mandate PLC asset discovery, patching, and segmentation as governance priorities.
