After the Mumbai terror strikes, anti-India elements in Pakistan are now planning an attack on Indian computer networks, intelligence agencies have warned.

Already Pakistani hackers are trying out a dry run against Indian networks through popular websites registered there after the Mumbai terror strikes, Home Ministry sources said in New Delhi on Tuesday.

"Every time the relations between the two countries dampen, Pakistanis start attacking Indian computer networks and this has increased after the Mumbai terror attacks," a Home Ministry source said.

Pakistani hackers have created websites such as the www.songs.pk, which are infested with software to hack data from the targeted computers, it said.

"The website www.songs.pk has over 12 lakh Indian users who are downloading stuff from these websites daily," said a cyber expert in the Ministry.

With these websites being highly popular, it will take only a few minutes for the hackers to take command of over 12 lakh computers in few minutes and the number of such computers can multiply in every minute, sources said.

"Instead of the existing less harmful virus, new ones such as Botnet and Zoombie can be easily released into the Indian computers, which later on replicate and make the entire server vulnerable," the expert said.

"Nowadays new virus and worms are detected while downloading songs from these websites, which could be just a dry run to manage a bigger attack," he said.

Government websites have been highly vulnerable to hacking and they have been intruded many times by the Pakistani hackers.
