US government says Iran-linked hackers are disrupting American water and energy providers

U.S. federal agencies (FBI, NSA, DOE, CISA) warn that Iranian state-backed hackers are actively compromising internet-exposed programmable logic controllers (initially Rockwell, now also Schneider Electric and Siemens) at American water and energy providers to manipulate displays and change controller logic, disabling shutdowns and alarms and creating outages and unsafe conditions; the activity is described as disruptive and likely motivated by regional conflict, and is accompanied by other destructive and leak operations attributed to groups like Handala.
