Dhaka: Michigan has reported cyberattacks targeting nine of its water systems, joining neighboring Minnesota, where more than 30 systems were recently affected. The FBI is investigating the incidents amid concerns over Iranian-linked cyber threats.

According to United News of Bangladesh, Michigan officials stated that the state received a federal cyber alert on Tuesday, warning of attempts to compromise operational technology used by water utilities. Shortly after this alert, several communities reported suspicious activity that matched the federal warning.

Dale George, communications director at Michigan’s Department of Environment, Great Lakes, and Energy, reported that nine water systems were impacted, but all continued operating safely. Local operators resolved the issues, and there were no known public health risks.

The FBI has confirmed that it is working with federal partners to protect critical infrastructure but has not yet identified those responsible for the attacks. Last week, the FBI and the Cybersecurity and Infrastructure Security Agency issued a warning that Iranian hackers have increasingly targeted water and wastewater systems and other critical infrastructure.

In Minnesota, officials noted that most confirmed attacks involved remote monitoring and control technology rather than direct disruption of water services. Braham briefly asked residents to reduce water use after a cyberattack shut down its water treatment controls, while Plymouth restored communications following a separate attack.

President Donald Trump blamed Minnesota officials for the incidents without providing evidence, which prompted Democratic Governor Tim Walz to respond. Walz clarified that Trump was aware the attacks had affected multiple states.
