CISA warns of cyberattacks disrupting U.S. water utilities
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) reported a rise in cyberattacks targeting internet-exposed programmable logic controllers (PLCs) used in water and wastewater treatment systems. The attacks threaten critical infrastructure that serves millions of residents and businesses across the country.
Why it matters: Water utility operators and asset owners must assess PLC exposure and network segmentation immediately to prevent operational disruption or public health impacts; CISA's warning signals active targeting of this sector.
