Intelligence Summary
CISA is advising water and wastewater utilities to harden operational technology (OT). The guidance follows intrusions that reached dozens of Minnesota water systems. The focus is on controllers and PLCs that are reachable from the internet. Utilities are urged to reduce exposure, lock down remote access, and monitor OT networks more closely. The risk is increased likelihood of disruption to essential water services if attackers gain control of industrial processes.
Recommended Action
Prioritize immediate review, validate exposure, and patch or mitigate affected systems.
