Michigan has reported suspicious cyber activity at nine water systems, joining more than 30 affected systems in Minnesota. Officials say Michigan’s systems continued operating safely, with no known public-health impact. The FBI is tracking incidents reported by utilities in at least seven states, but several states and most affected facilities remain publicly unidentified. Wisconsin has confirmed no compromises, while Rapid City’s separate incident has not been linked to the wider PLC-focused campaign. U.S. intelligence reportedly suspects an Iran-linked operation, but the FBI has not formally attributed the campaign.
