Colorado Water Utilities Hit by Cyberattacks Targeting OT Systems
By Eduard Kovacs
AI Summary
Hackers attacked Colorado water utilities by targeting operational technology (OT) systems, changing equipment settings, disabling remote access and alarms, and altering pumping cycles — a rare confirmed instance of cyberattacks causing direct manipulation of physical water infrastructure. This underscores the critical risk to ICS/SCADA environments in the water sector, which has seen increased threat actor attention in recent years. Security teams managing OT networks should audit remote access controls and alarm integrity immediately.
