Iran hackers hit 30 Minnesota public water systems in coordinated cyberattack

The suspected hackers have breached US water infrastucture before – and CISA has just warned their targets are expanding.

In at least one city, the attack temporarily knocked a municipal well and water treatment plant offline, according to local media outlet MPRNews.

Other communities reported the attacks disrupted communications and automated operations, forcing staff to switch to manual workarounds while systems were restored, the news outlet said.
