Dozens of Minnesota Water Utilities Targeted in Coordinated OT Attacks

Dozens of water utilities in Minnesota were targeted in a coordinated cyberattack on their operational technology (OT) systems. While services remained operational, attackers disrupted automated control functions, leading to temporary shutdowns and prompting a reevaluation of vulnerability studies. The attacks follow warnings about Iran-linked threats targeting similar industrial control systems, and investigators are working to determine the common thread and scope of the attacks, highlighting the potential for similar vulnerabilities in water infrastructure beyond Minnesota.
