China's National Computer Virus Emergency Response Center (CVERC) has doubled down on claims that the threat actor known as the Volt Typhoon is a fabrication of the U.S. and its allies.

The agency, in collaboration with the National Engineering Laboratory for Computer Virus Prevention Technology, went on to accuse the U.S. federal government, intelligence agencies, and Five Eyes countries of conducting cyber espionage activities against China, France, Germany, Japan, and internet users globally.

It also said there's "ironclad evidence" indicating that the U.S. carries out false flag operations in an attempt to conceal its own malicious cyber attacks, adding it's inventing the "so-called danger of Chinese cyber attacks" and that it has established a "large-scale global internet surveillance network."

"The U.S. military base in Guam has not been a victim of the Volt Typhoon cyber attacks at all, but the initiator of a large number of cyberattacks against China and many Southeast Asian countries and the backhaul center of stolen data."
