A coordinated cyberattack struck more than 30 Minnesota community water systems Sunday and Monday, Minnesota IT Services (MNIT) confirmed Tuesday. The attack briefly knocked a water plant in Braham offline Monday morning before crews restored it within two hours. Three other communities — Maple Plain, Plymouth, and South St. Paul — also reported attempted intrusions.

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 has activated a statewide response and is still assessing the full scope. Experts warn the attacks signal that water facilities need stronger cybersecurity — likely meaning higher water bills ahead.
