On February 28, 2013, China’s Defense Ministry held a press conference at which its spokesperson, Geng Yansheng, claimed that hackers from the United States have launched frequent attacks against China’s military websites. Geng stated, “In 2012, according to the IP addresses of the display, the websites of China’s Ministry of Defense and military newspaper PLA Daily suffered attacks from the outside on an average of 14.4 million time per month. Attacks from the United States accounted for 62.9 percent of the total.”
Geng also stated, “A number of China’s military websites have faced serious threats from cyber attacks since their inception. In recent years, the number of attacks has shown an upward trend. We noticed that the U.S. media recently reported that the United States will adopt the policy of "pre-emptive" cyber attacks, expand network warfare units on a large-scale, and establish rules for cyber warfare. The above practices are not conducive to the joint efforts of the international community to enhance Internet security. We hope that the United States will explain and clarify its position.”
