The hacker also reprogrammed pages of Tsinghua University's in-house course portal to display Arabic verses from Islamic scripture accompanied by music, a student newspaper at the Beijing institution reported.
Instead of displaying links to class resources and departmental information, the site showed a photo of four hooded fighters on horseback riding beneath the flag of Islamic State, according to screenshots.
The cyber-intruder identified himself as an "Islamic State Hacker".
The student newspaper report was widely reposted by state-run media, but the original has since been deleted.

Tsinghua, in Beijing, quickly shut down the server after the breach on Sunday evening was discovered, the reports said.
