The U.S. is invoking Cold War-era national-security powers to force telecommunication companies including AT&T Inc. and Verizon Communications Inc. to divulge confidential information about their networks in a hunt for Chinese cyber-spying.
In a survey distributed in April, the U.S. Commerce Department asked for a detailed accounting of foreign-made hardware and software on the companies’ networks. It also asked about security-related incidents such as the discovery of “unauthorized electronic hardware” or suspicious equipment that can duplicate or redirect data, according to a copy of the survey reviewed by Bloomberg News.
