Cyberattacks Target Water and Sewer Systems Across Multiple U.S. States

Water and sewer systems in at least 12 U.S. states have recently reported cyberattacks, with the FBI attributing some incidents to 'malicious cyber actors' linked to Iran or proxy groups. Reported operational effects include loss of pressure and flooding, with attacks targeting Operational Technology (OT) devices, specifically Rockwell Automation/Allen-Bradley Programmable Logic Controllers. Local officials, such as those in Fort Smith, Arkansas, are taking proactive measures to protect regional water supplies.
