Goa Information Technology Corporation Chairman Subhash Faldesai said the state Home Ministry would be informed about the hacking, particularly because the hackers have left a message of "Pakistan Zindabad" on the main pages of the portals.
"It has to be identified whether the pro-Pakistan message on the front page was a threat by terrorists or just a mischief," he said.
IT Corporation, which is handling the data of all government websites through a private vendor, has decided to strengthen its anti-hacking protection.
