The FBI informed one of President-elect Donald Trump’s top lawyers that his phone had been tapped by Chinese hackers, three sources familiar with the matter told CNN, as part of a broad operation targeting top officials Republican and Democratic officials in US politics.

The FBI informed the attorney, Todd Blanche, last week that hackers were able to obtain voice recordings and text messages from his phone, but none of the information was related to Trump, a source said. The FBI provided Blanche, who had to start using a different number after the breach, what the hackers hacked, including communication with her family, the source said. CNN has contacted the FBI for comment.

Blanche is the second of two Trump lawyers said to be targeted by foreign hackers. In August, CNN reported that attorney Lindsey Halligan was targeted in another Iranian hacking operation, although the timing of that attempt and the extent of any breach of her devices or accounts are unknown clear.

Chinese hackers have also targeted other high-profile figures in Trump’s orbit, including Trump himself and Vice President-elect Sen. JD Vance. Other targets include Trump’s son-in-law Jared Kushner, his son Eric Trump, members of the Harris-Walz campaign and members of the Biden administration, CNN previously reported.

The sophisticated hacking operation worried national security officials because of the deep access the Chinese hackers had to the phone calls and records of high-profile Americans. US officials investigating the hacking campaign, which took place through intrusions into US telecommunications companies AT&T, Lumen and Verizon, consider it one of the world’s biggest national security attacks in recent years.

The scale of the hack is “much worse than the public knows,” and officials are still reviewing the intrusions to determine their impact, another intelligence source told CNN.
The Chinese government has denied US accusations that it was behind the hack. Chinese spies have forced US government employees to take unusual security measures. The Consumer Financial Protection Bureau (CFPB), for example, has asked its employees to only use Microsoft Teams and Cisco WebEx to conduct work activities involving non-public information, a CFPB spokesperson told CNN on Thursday .

There is no evidence that the CFPB has specifically targeted hackers, the spokesman said. The Wall Street Journal was the first to report on the CFPB’s security protocol.
