Three members of Congress have asked the U.S. Justice Department to investigate how foreign hackers breached a water authority near Pittsburgh, prompting the nation's top cyberdefense agency to warn other water and sewage-treatment utilities that they may be vulnerable.
In a letter released Thursday, U.S. Sens. John Fetterman and Bob Casey and U.S. Rep. Chris Deluzio said Americans must know their drinking water and other basic infrastructure is safe from “nation-state adversaries and terrorist organizations.”
