Coordinated Cyberattack Targets 30+ Minnesota Water Systems as One Plant Goes Offline
Summary: A coordinated cyberattack hit operational technology at more than 30 Minnesota community water systems on July 26 and 27, with Braham's water plant going offline and Plymouth, South St. Paul and Maple Plain reporting communications failures or affected automated controls. Minnesota IT Services said the incidents shared common timing, access methods and targeted infrastructure, and that investigators have not identified the attacker, affected products, exploited vulnerability or whether data was stolen.
Why it matters: More than 30 water systems were affected in a single weekend, and four days earlier federal agencies had warned that Iranian-affiliated actors were targeting internet-facing programmable logic controllers, with the FBI and EPA later reporting incidents at utilities in at least seven states involving Rockwell Automation/Allen-Bradley MicroLogix 1100 and 1400 PLCs.
