A coordinated cyberattack struck more than 30 Minnesota community water systems on 26 and 27 July, Minnesota IT Services (MNIT) confirmed on 28 July. The attack briefly knocked a water plant in Braham offline on the morning of 27 July before crews restored it within two hours. Three other communities were also hit: Maple Plain and South St. Paul both lost some automated control functions, and Plymouth lost communications at two water towers and multiple lift stations. All three kept operating manually.

Officials say the goal appears to be disruption rather than financial gain or public harm. Water quality and safety remain unaffected across all impacted cities. MNIT activated a statewide response and was still assessing the full scope in the days after the attack. Minnesota was not alone — the FBI has since confirmed water systems were targeted in at least seven states, including Michigan and Georgia. One security expert warned the attacks signal that water facilities need stronger cybersecurity, which will probably mean higher water bills.
