The Salt Typhoon hack is one of the largest attacks on US telecommunications ever, officials say. Senate Intelligence Committee Chairman Mark Warner told The Washington Post that the hack is the "worst telecom hack in our nation's history by far." Senior White House officials on the call said the hack has been ongoing for "likely one to two years." She added that the White House "has made it a priority for the federal government to do everything it can to get to the bottom of this." Neuberger said that White House leaders are meeting three times a week to discuss the hack.
