In a multiyear campaign called Salt Typhoon, threat actors from the People’s Republic of China (PRC) have broken into many major telecom providers, including Verizon, AT&T, and T-Mobile. Collectively, 397.1 million users subscribe to these three telecom providers, indicating that Salt Typhoon could impact hundreds of millions of people. Due to the magnitude of this data breach, Sen. Mark Warner (D-Va.), vice chairman of the Senate Select Committee on Intelligence, claimed Salt Typhoon is the “worst telecom hack in our nation’s history.” As former FBI director, Christopher Wray claimed Salt Typhoon is the “most significant cyber espionage campaign in history.”
