New US advisory: Iran-linked actors manipulating Rockwell, Siemens and Schneider PLCs
A US government advisory (CISA/FBI/NSA/EPA), updated July 22, warns Iran-linked actors are using vendors' own engineering software to alter project files on Rockwell, Siemens (S7-1200) and Schneider (Modicon M340) PLCs — disabling shutdown and alarm logic at US water, energy and government facilities, with at least one confirmed US victim. No direct AI angle, but a strategically significant critical-infrastructure escalation.
