Department of Homeland Security and FBI disagree that Illinois water utility’s industrial control systems were hacked. DHS and FBI issued a joint statement disputing the claims made by the Illinois State Fusion Center. ICS-CERT said it “could not validate the claims” made in the report, though it added that the investigation was continuing. Security expert Joe Weiss, managing partner of consultancy Applied Control Solutions, said the inability of the government agencies involved to agree on what had happened was troubling, especially since Fusion Centers were created to quickly issue public infrastructure alerts in the wake of suspected attacks.”]
