CISA still finds water system controls exposed online amid multistate hacks
CISA, working alongside the FBI, is responding to a wave of cyberattacks hitting water systems across multiple states. The agency has not attributed the intrusions to any specific group, according to acting director Nick Andersen.
Why this matters: Water system controls exposed on the open internet is a basic, fixable problem. It keeps showing up anyway. When attackers can reach the systems that manage pressure, treatment chemicals, and flow, the consequences are not a data breach — they are a public health event. CISA is helping victims after the fact, which matters less than the fact that these systems were reachable in the first place. Utilities need to answer for that, not just wait for federal agencies to show up after something goes wrong.
