AI scripts target exposed Siemens PLCs

Five U.S. agencies now call AI-assisted attacks on Siemens S7 programmable logic controllers an active threat, according to CISA’s joint advisory. The notice says actors are using AI-generated exploitation scripts against exposed or poorly protected controllers across water, energy, manufacturing, chemical, food, and commercial facilities; The Register’s report says the activity lowers the skill barrier for industrial attacks. Operators should inventory, patch, isolate, and monitor OT assets—not wait for a model-specific detector—building on the archive’s agency-by-agency AI cyber ownership framework.
