Automated controls at 36 municipal water systems across Minnesota were knocked offline in a coordinated cyberattack suspected to involve Iran-linked hackers, forcing human crews in towns such as Braham to isolate equipment and restart critical machinery by hand. It took roughly 90 minutes on Monday morning for staff in Braham, a town of around 1,700 people, to bring the local water plant back under manual control after its systems went dark, according to CBS Minnesota. A Minnesota state fusion center report ties the cyberattacks on 30+ Minnesota water utilities to Iranian-affiliated hackers, according to a water utility information sharing group's memo I obtained. https://t.co/32EpwxXIX5 — Andy Greenberg (@agreenberg at the other places) (@a_greenberg) July 30, 2026How Minnesota's Water Systems RecoveredBy Wednesday afternoon, Mr Israel confirmed there was no evidence that any of the breaches had contaminated drinking water or disrupted its delivery to residents.
