A Pakistan government website was apparently hacked on Thursday. Online pictures the hackers posted purportedly showed Indian national anthem and Independence Day greetings on the message board. The official website display of a message "Official gateway to the Pakistan government" was later restored. The attack came months after a pro-Pakistan group hacked the official websites of four prominent Indian institutes -- Indian Institute of Technology Delhi (IIT Delhi), IIT Varanasi, Aligarh Muslim University (AMU) and Delhi University (DU). The group -- "Pakistan Haxors Crew" -- said: "Nothing deleted or stolen. Just here to deliver my message to Indians."
