U.S. intelligence agencies are “urgently warning” private-sector companies nationwide that Iranian actors are conducting cyber operations targeting critical U.S. infrastructure, a campaign that has already caused disruptions. … [T]he EPA warned that Iran’s cyberattack had already disrupted “commonly used operational technology at drinking water and wastewater systems,” and that the federal government is “diligently working to ensure that Americans can rely on clean and safe water.” “Cyberattacks on drinking water and wastewater systems directly threaten public health and community resilience,” Jeffrey A. Hall, the EPA’s assistant administrator for enforcement and compliance assurance, said in a statement.
