WASHINGTON (AP) — Federal authorities on Tuesday urged telecommunication companies to boost network security following a sprawling Chinese hacking campaign that gave officials in Beijing access to private texts and phone conversations of an unknown number of Americans.

The guidance issued by the FBI and the Cybersecurity and Infrastructure Security Agency is intended to help root out the hackers and prevent similar cyberespionage in the future. Officials who briefed reporters on the recommendations said the U.S. still doesn't know the true scope of China's attack or the extent to which Chinese hackers still have access to U.S. networks.
