China-linked hackers stole surveillance data from telecom companies: US

China-linked hackers have intercepted surveillance data intended for American law enforcement agencies after breaking in to an unspecified number of telecom companies, U.S. authorities said on Wednesday.

The hackers compromised the networks of “multiple telecommunications companies” and stole U.S. customer call records and communications from “a limited number of individuals who are primarily involved in government or political activity,” according to a joint statement released by the FBI and the U.S. cyber watchdog agency CISA.
