Cyberattacks have struck water utilities in Colorado, with attackers targeting operational technology systems, according to SecurityWeek. Officials said the intruders changed equipment settings, disabled remote access and alarms, and altered pumping cycles, potentially disrupting normal water operations.

The incidents specifically hit OT systems, which control physical infrastructure such as pumps and monitoring equipment. Disabling alarms and remote access can leave operators blind to problems, while tampering with pumping cycles may affect water pressure or flow.

The report did not name the affected utilities or describe the full impact. The attacks underscore the persistent risk that cybercriminals or other threat actors pose to critical infrastructure, where even small changes to equipment behavior can have serious consequences.
