China has claimed that two of its key military sites faced 144,000 cyber attacks per month in 2012, with the majority of those attacks originating in the United States.
"The defence ministry and China military online websites have faced a serious threat from hacking attacks since they were established, and the number of hacks has risen steadily in recent years," said Geng Yansheng, a government spokesman.
In what is increasingly being described as a cyberspace cold war, the two superpowers have traded a volley of accusations regarding digital breaches. However, this is the first time China has revealed detail about the severity or frequency of the alleged attacks.
"According to the IP addresses, the websites were, in 2012, hacked on average from overseas 144,000 times a month, of which attacks from the US accounted for 62.9%," Yansheng added.
Meanwhile, across the Pacific, a US computer security firm last month published a report suggesting a Chinese military unit was responsible for perpetrating a series of sophisticated cyber attacks throughout the world, majority of which were targeted at the US. China denied the allegations, claiming that it was a victim of such attacks.
