Faculty members at Shanghai Jiaotong University, one of the top universities in China, have been linked to the People's Liberation Army Unit 61398, the same group that's been accused of hacking several companies based in the U.S. and several media outlets.
Shanghai Jiaotong University is linked with PLA Unit 61398, however there is no evidence that shows that they were involved in the cyber-espionage attacks against the U.S. Faculty at the university's School of Information Security Engineering (SISE) have collaborated in the past with the PLA unit on several research papers on cyber-security.
For example, Xue Zhi, the Vice President of SISE who also developed China's leading cyber attack platform, collaborated with Chen Yi-qun, a researcher for the PLA, on a paper about improving security by designing a collaborative network monitoring system.
Fan Lei, who is an associate professor at the university, also worked on a research paper with Chen. Fan said that he did not know that Chen was a part of PLA Uit 61398, and only worked with him because he was a SISE graduate. This statement, however, was proven to be false by the research paper itself, which stated that Chen was a part of the PLA unit.
