China says US-based hackers attack its military websites

Hackers mainly based in the United States attacked two Chinese military websites, including the Defence Ministry page, an average of 144,000 times a month last year, the ministry said on Thursday.

China's first account of attacks on its websites steps up a war of words between the powers, after a US security company said last week that a Chinese military unit was behind a series of hacking attacks on US firms.

"The Defense Ministry and China Military Online websites were hacked from overseas on average 144,000 times a month in 2012," ministry spokesman Geng Yansheng said on its website.

China Military Online is a People's Liberation Army news website.

More than 62 percent of the attacks came from the United States, he said, adding that the number of hacking assaults on military websites "has risen steadily in recent years."

Such efforts are "not conducive to the joint efforts of the international community to enhance network security", he said.

Hacking accusations have strained ties between Washington and Beijing, with State Department spokeswoman Victoria Nuland saying this month that hacking comes up "in virtually every meeting we have with Chinese officials".
