Minnesota State Officials

Minnesota officials disclosed a coordinated cyberattack targeting more than 30 community water systems between July 26 and July 27, 2026. Several communities, including Braham, Plymouth, South St. Paul and Maple Plain, reported disruptions to operational technology supporting water treatment, although officials stated there was no impact to drinking water quality or public safety. In Braham, the attack temporarily shut down the city's water treatment plant until operators restored service using manual processes. The incident is one of the largest coordinated cyberattacks against U.S. municipal water systems publicly disclosed to date and underscores the continued targeting of critical infrastructure.
