A U.S. intelligence agency gained access to China’s telecommunications network after hacking a university, Chinese state media claimed Thursday. CNBC reports: The U.S. National Security Agency used phishing — a hacking technique where a malicious link is included in an email — to gain access to the government funded Northwestern Polytechnical University, the Global Times alleged, citing an unnamed source. American hackers stole “core technology data including key network equipment configuration, network management data, and core operational data,” and other files, according to the Global Times. As part of the NSA’s hack, the agency infiltrated Chinese telecommunications operators so that the U.S. could “control the country’s infrastructure,” the Global Times alleged. The Global Times, citing its unnamed source, reported that more details about the attack on Northwestern Polytechnical University will be released soon. China first disclosed the alleged attack on the Northwestern Polytechnical University earlier this month. “The agency also accused the U.S. of engaging in ‘tens of thousands’ of cyberattacks on Chinese targets,” adds CNBC.
