"In April 2008, Indian intelligence agencies detected Chinese hackers breaking into the computer network of the Ministry of External Affairs forcing the government to think about devising a new strategy to fortify the system. Though the intelligence agencies failed to get the identity of the hackers, the IP addresses left behind suggested Chinese hands."
The article rambles somewhat between discussion of web defacements in India (with no apparent link to China) and discussion of India's vulnerability to cyber attacks:
"Unless India takes adequate steps to protect itself from external cyber threats, the world famous IT giant could be facing a grim situation. Cyber attacks are dangerous for India because of the growing reliance on networks and technology to control critical systems that run power plants and transportation systems. Cyber attacks on banks, stock markets and other financial institutions could likewise have a devastating effect on a nation's economy.
"As a countermeasure, the Indian armed forces are trying to enhance their C4ISR capabilities, so that the country can launch its own cyber offensive if the need arises. Given Chinese cyber attacks, there is need for the army to fight digital battles as well."
