Cyberattack shuts down Braham water treatment plant during coordinated Minnesota OT campaign
A malicious cyberattack against computerized operating systems at the City of Braham temporarily knocked its well and water-treatment plant offline on 27 July 2026. The plant remained offline for just under two hours while the city relied on limited water stored in its tower and asked residents to minimize use; service returned without reported water-quality or safety impact.
