WASHINGTON (Reuters) -Chinese hackers who tapped into Verizon (NYSE:VZ)'s system targeted phones used by people affiliated with the campaign of Democratic presidential candidate Kamala Harris, a person familiar with the situation said on Friday.
Republican presidential candidate Donald Trump and his running mate, JD (NASDAQ:JD) Vance, were also targeted, according to media reports. Reuters could not confirm those reports.
The New York Times reported investigators were working to determine what communications, if any, were taken from Trump and Vance.
The Trump campaign was made aware this week that Trump and Vance were among a number of people inside and outside of government whose phone numbers were targeted through the infiltration of Verizon phone systems, the Times report added.
The Trump campaign did not confirm that Trump's and Vance's phones were targeted. Steven Cheung, the campaign's communications director, said Vice President Harris has emboldened China and Iran to attack U.S. infrastructure to prevent Trump from returning to office.
China's embassy in Washington and the Harris campaign did not immediately respond to requests for comment.
The Trump campaign was hacked earlier this year. The U.S. Justice Department charged three members of Iran's Revolutionary Guard Corps with the hack, accusing them of trying to disrupt the Nov. 5 election.
The FBI and the U.S. Cybersecurity and Infrastructure Security Agency said on Friday they were investigating unauthorized access to commercial telecommunications infrastructure by people associated with China. The joint statement by the agencies did not name the targets of the incident.
Verizon said it was aware of a sophisticated attempt to reportedly target U.S. telecoms and gather intelligence.
The largest U.S. telecom company added it was working with law enforcement.
