Coordinated Cyberattack Targets 30+ Minnesota Water Systems as One Plant Goes Offline

A coordinated cyberattack targeted the operational technology of over 30 community water systems in Minnesota. The attack occurred on July 26 and 27, prompting a statewide cybersecurity response. Several cities, including Braham, Plymouth, South St. Paul, and Maple Plain, reported issues such as plant outages, communications failures, and problems with automated controls. Braham's water plant was forced offline, and the city requested that residents reduce their water usage. The attack affected multiple water systems across the state, disrupting normal operations.
