Summary
The CISA is urging water and wastewater systems to rapidly secure their operational technology (OT), specifically programmable logic controllers (PLCs), following a coordinated cyberattack in Minnesota that disrupted automated controls at over 30 community water systems. The agency is warning of an increase in Iran-linked attacks targeting PLCs from vendors like Rockwell Automation, Schneider Electric, and Siemens, and recommends immediate steps to disconnect PLCs from the internet and implement robust security measures.
