US water system cyberattacks blamed on Iran, Trump attacks Minnesota
Federal investigators reported that malicious cyber actors compromised operational technology at municipal water and wastewater systems in at least seven U.S. states, including Minnesota and Michigan. The attacks targeted Rockwell Automation/Allen‑Bradley programmable logic controllers, specifically the MicroLogix 1100 and 1400 series, causing loss of remote monitoring and control. The FBI, EPA and CISA issued public alerts and are working with state officials to secure the affected infrastructure. No contamination of water supplies or widespread service interruptions have been confirmed, and operators restored manual control at the impacted sites.
U.S. officials suspect Iranian‑linked threat actors, with groups such as “Cyberavengers” and “Handala” mentioned as possible perpetrators. President Donald Trump publicly blamed Minnesota and Governor Tim Walz for the incidents, rejecting the notion of Iranian involvement. Israel’s National Cyber Directorate also noted similar threats to its water sector and confirmed ongoing cooperation with U.S. counterparts on the matter.
