Beijing has angrily denied claims that Chinese hackers had attacked Indian government computers, just one week after Google threatened to pull out of China over similar accusations, AFP reported. Chinese foreign ministry spokesman Ma Zhaoxu branded the accusations groundless, and argued that China itself was the biggest victim of hacking. "The Chinese government is firmly against hacking activities and will deal with relevant cases in accordance with the law," he said. India’s national security advisor confirmed in an interview published on Monday that his office and other government departments were targetted with an email that contained a "Trojan" virus, which would allow a hacker remote access to Indian government computers. The Indian authorities suspect that the email came from within China. "This was not the first instance of an attempt to hack into our computers," national security advisor M. K. Narayanan told The Times of London. "People seem to be fairly sure it was the Chinese. It is difficult to find the exact source but this is the main suspicion. It seems well founded," he said.
