A 9th telecoms firm has been hit by a massive Chinese espionage campaign, the White House says

The hackers compromised the networks of telecommunications companies to obtain customer call records and gain access to the private communications of what officials have said is a a limited number of individuals. Though the FBI has not publicly identified any of the victims, officials believe senior U.S. government officials and prominent political figures are among those whose whose communications were accessed.

Neuberger said Friday that officials did not yet have a precise sense how many Americans overall were affected by Salt Typhoon, in part because the Chinese were careful about their techniques, but that a “large number” were in the Washington-Virginia area.

Officials believe the goal of the hackers was to identify who owned the phones and, if they were “government targets of interest,” spy on their texts and phone calls, she said.

The FBI said most of the people targeted by the hackers are “primarily involved in government or political activity.”

Neuberger said the episode highlighted the need for required cybersecurity practices in the telecommunications industry, something the Federal Communications Commission is to take up at a meeting next month. In addition, she said, the government was planning additional actions in coming weeks in response to the hacking campaign, though she did not say what they were.

“We know that voluntary cyber security practices are inadequate to protect against China, Russia and Iran hacking of our critical infrastructure,” she said.

The Chinese government has denied responsibility for the hacking.
