The New York Times reported last week that the cyber attacks on Google and other American companies have been traced to Shanghai Jiaotong University and Lanxiang Vocational School in the Shandong province. The news was reportedly based on an IP address.
Li Zixiang at Lanxiang, another alleged source of the attacks, dismissed the report that suggested the involvement of a Ukrainian professor, Xinhua reported.
"There is no Ukrainian teacher in the school and we have never employed any foreign staff," Li said, as cited by Xinhua.
Google had suffered a "highly sophisticated and targeted attack" in December, allegedly from inside China.
