HPSCI Ranking Member Turner Calls for Hardening Critical Infrastructure After FBI Warns of Water System Cyberattacks Across Multiple States

The FBI and EPA warned that malicious cyber actors have targeted internet-facing Rockwell Automation/Allen-Bradley programmable logic controllers at water and wastewater utilities in at least seven states since July 27, changing IP addresses and passwords and, in some cases, degrading operations including loss of pressure and flooding 1. More than 30 Minnesota water systems and nine in Michigan reported disruptions, prompting some utilities to shift to manual operations, though officials said no evidence has emerged of drinking-water contamination 2. Investigators are examining whether Iranian hackers are responsible, but CBS News reported no public attribution has been made 23; President Trump said he did not believe Iran was behind the incident and said Minnesota's leadership was "grossly incompetent" 4. Rep. Mike Turner, R-Ohio, ranking member of the House Intelligence Committee, told CBS's "Face the Nation" that Congress has not been told which states are affected or whether Ohio is among them, and said critical infrastructure "need[s] to be hardened" against adversaries including Iran, Russia, China and North Korea 25.
