US Investigating If Iran Hit Over 30 Minnesota Water Systems

State officials say the attack disrupted remote controls at more than 30 community water systems, forcing crews to switch to manual operations.

  • On July 26 and 27, a "coordinated cyberattack" disrupted operational technology at more than 30 Minnesota community water systems, prompting immediate activation of state cybersecurity response capabilities by Minnesota IT Services .
  • Security researchers suspect the Iran-linked group CyberAv3ngers, which targets small municipal water facilities, may be responsible, though officials have not confirmed attribution for the attacks.
  • Automated controls in Braham, Minnesota and Plymouth, Minnesota were disrupted, forcing utility crews to switch to manual procedures; water quality and safety remained unaffected during the outages.
  • State and federal agencies are collaborating with MNIT to investigate the intrusion and strengthen defenses, with "water levels and water quality unaffected," according to officials.
  • Cybersecurity experts warn of a "worrying expansion in Iran-linked critical infrastructure targeting" across the United States, with small municipal systems particularly vulnerable due to limited dedicated security resources.
