U.S. authorities are investigating a coordinated cyberattack that targeted programmable logic controllers (PLCs) used to monitor and control equipment in over 30 community water systems across Minnesota and nine in Michigan, according to CBS News, Reuters, and Al Jazeera. The attack forced some utilities to switch to manual operations as state and federal authorities work to determine the origin. Initial suspicions point to Iranian hackers or a false-flag operation intended to heighten tensions amid ongoing U.S.-Iran conflict, per sources familiar with the incident.

The Cybersecurity and Infrastructure Security Agency (CISA) issued a warning about increased targeting of PLCs in the Water and Wastewater Systems sector. The FBI has confirmed its awareness of the incidents and is in contact with victims but declined to provide additional information about potential Iranian involvement, according to Reuters. CISA urged critical infrastructure owners and operators to remove publicly exposed PLCs from the internet as soon as possible.
The EPA has warned that many local water systems have vulnerabilities, including outdated software, poor network security, weak access controls, and lack of employee cybersecurity training. However, it indicated that individual operators are responsible for protecting their own systems from external threats according to The New York Times.
The Guardian reported that Minnesota appeared to be the hardest hit with 30 of its water systems experiencing disruptions in the state’s water supply. Cities like South St. Paul and Braham experienced issues but were able to continue services without interruption by implementing contingency procedures, according to CBS News. The FBI and EPA issued a joint statement noting that hackers remotely accessed internet-connected controls, changed administrator passwords, and caused operational disruptions such as flooding and pressure loss.
The New York Times reported that there has been no indication that any water supply is unsafe to drink. Michigan also reported attacks, with Dale George, director of communications for Michigan's Department of Environment, Great Lakes and Energy, stating that all systems continued to operate safely and there were no known impacts posing a public health concern according to UPI. The investigation remains ongoing.
The Conversation detailed how hackers targeted small computers in equipment like pumps and valves that deliver drinking water. Utilities countered the attacks by shutting down control computers and operating equipment manually. The article noted that about 152,000 public drinking water systems in the United States are vulnerable due to outdated software and poor network security. The FBI and EPA advisory stated that attackers remotely accessed Rockwell Automation MicroLogix PLCs connected directly to the internet.
