The Chinese state media claimed that a U.S. intelligence agency gained access to China's telecommunications network.
The Global Times reported that the U.S. National Security Agency used a hacking technique called "phishing" to gain access to the university.
According to the Global Times, American hackers stole "core technology data including key network equipment configuration, network management data, and core operational data"
According to the Global Times, the agency eavesdropped on Chinese telecommunications operators in order to control the country's infrastructure.
When contacted by CNBC, the National Security Agency was silent. CNBC doesn't know if the hack is real.
More information about the attack on the university will be released soon, according to the Global Times.
China has accused the U.S. of cyberattacks for a long time. In the last few weeks, Beijing has been more vocal in blaming the U.S. for attacks on it's computers.
Washington and American firms have blamed attacks on China in the past.
The National Computer Viruses Emergency Response Center in China first reported the attack on the university. The agency said the U.S. engaged in tens of thousands of cyberattacks on Chinese targets.
The U.S. has accused China of large-scale hacking. Christopher Wray, director of the Federal Bureau of Investigation, said in February that China's cyberattacks have become more brazen, more damaging, than before.
China was accused of attempting to steal information and technology.
