A coordinated cyberattack targeted operational technology at more than 30 Minnesota community water systems on July 26 and 27, triggering a statewide cybersecurity response. Braham, Plymouth, South St. Paul and Maple Plain have publicly described a plant outage, communications failures or affected automated controls. Braham's water plant went offline, and the city asked residents to minimize water use until treatment resumed. Plymouth reported cellular communications problems at two water towers and multiple wastewater lift stations but continued operating manually. South St. Paul and Maple Plain maintained services after automated utility controls were affected, with Maple Plain declaring a local state of emergency to support its response. Minnesota IT Services (MNIT) said on July 28 that it was not aware of any active requests for residents to change their drinking-water use. Officials have not publicly identified the attacker, affected products, exploited vulnerability, or whether data was stolen. "At this point, we can confirm that more than 30 water systems throughout the state were impacted," MNIT told The Hacker News. "The nature and extent of the impact varied by system, and the investigation is still determining how many experienced operational disruptions." MNIT said the incidents shared common characteristics, including their timing, methods of access and the type of infrastructure targeted. Those similarities supported the state's description of the activity as coordinated. The agency said the similarities were consistent with activity observed by federal partners in other states and industries, but investigators could not yet determine whether a single actor was responsible for all the incidents. Investigators have also identified similarities in how the systems were accessed, MNIT said, but the agency is not sharing specific technical details while the investigation continues. Attribution has not been finalized. MNIT said it is coordinating containment, investigation, recovery and threat-intelligence sharing with state agencies, the Cybersecurity
