Water system cyberattacks spread to Georgia, Michigan amid US-Iran conflict

Multiple US states (including Minnesota, Georgia, and Michigan) reported hostile cyber activity against water and wastewater systems beginning late July 2026; the FBI and CISA issued advisories after observing attacks targeting Rockwell/Allen-Bradley PLCs and warning that Schneider Electric, Siemens, and other PLCs may also be targeted. Security researchers and some officials have publicly suspected Iran-affiliated actors (including IRGC-linked groups) while attribution remains unconfirmed; states reported limited operational degradation and no known public-health impacts, and federal guidance urged hardening of industrial control systems.
