On March 19, 2013, the National Emergency Response Center (CNCERT) released a report claiming that China faces a serious threat of cyber attacks from outside of China.
The report said that in 2012, there were about 73,000 Trojans or botnet network control servers (NCS) involved in the control of host servers in Chinese territory, a year-on-year increase of 56.9 percent; also, 1802 government websites were defaced (altered), a year-on-year increase of 21.4 percent.
The CNCERT report also stated that, in 2012, 12,891 network control servers from the United States controlled more than 10.512 million host servers in China. In addition, it stated that 96.2 percent of the fishing sites targeting China were located offshore, up to 83.2 percent of them being from the United States.
"The attacks on China’s Internet are mainly from the United States," reported Zhou Yonglin, director of the Operations Department of CNCERT.
