WASHINGTON — The U.S. Cybersecurity and Infrastructure Security Agency has issued an emergency directive instructing public water utilities in all 50 states to immediately disconnect internet-exposed industrial control systems after coordinated cyberattacks on more than 30 municipal drinking water systems in Minnesota. According to state officials and federal security advisories, the breaches compromised technology used to manage community water operations and locked plant operators out of core administrative networks, leaving staff unable to digitally monitor water quality, filtration processes, or chemical distribution. Federal authorities describe the action as a nationwide intervention aimed at preventing further disruptions to drinking water infrastructure and reinforcing the cybersecurity of critical systems that oversee treatment and delivery. BRAHAM, Minnesota — The attacks had direct operational impact in the city of Braham, where hackers disabled automated controls for the main water well and the primary water treatment plant, forcing utility workers to shift to manual emergency operations to keep water flowing. Local public health officials issued immediate boil-water notices to residents to guard against potential exposure to contaminated drinking water while digital monitoring remained inaccessible. An urgent memorandum to water-sector operators from the Water Information Sharing and Analysis Center, citing ongoing federal law enforcement investigations, reports that security agencies assess the intrusions as the work of state-sponsored cyber actors tied to Iran, and warns that foreign threat groups are intensifying efforts to scan, infiltrate, and sabotage vulnerable U.S. water and wastewater treatment facilities.
