The official websites of at least three central universities - Delhi University, Aligarh Muslim University, the Indian Institute of Technology-Banaras Hindu University (IIT-BHU) - were hacked on Tuesday and pro-Kashmir messages were splashed on them by a group that only identified itself as 'PHC'.
The IIT-Delhi website, which was also hacked, was restored today.
"Greetings Government of India, and the people of India. Do you know what your so-called heroes (soldiers) are doing in Kashmir? Do you know they are killing many innocent people in Kashmir?" the same message on all the affected sites read.
"Pakistan Zindabad," it says in fluorescent green at the bottom, with the page displaying two videos of the army's alleged brutalities in Kashmir and the protest of the people over it.
"Do you know they have raped many girls? Do you know they still are raping girls in Kashmir? How would you feel if your brother, sister, father and mother gets killed? How would you feel if someone rapes your mother or sister? Won't your life and your families be destroyed?" it added.
"This hack is in response to Code-Man's hack of railways.gov.pk (http://www.zone-h.org/mirror/id/29230257?zh=1) and in the solidarity of innocent Kashmiri people being killed by the Indian Army. Thank you, Regards - PHC," it says.
The websites of most central universities are managed by the state-run National Informatics Centre.
