China has become a major victim of international cybercrimes.

The latest PricewaterhouseCoopers (PwC) Global State of Information Security Survey shows that the average number of detected security incidents in the Chinese mainland and Hong Kong surged 517 percent to hit 1,245 over the last 12 months, compared with the average of 241 recorded the previous year, according to a Xinhua report.

In the first half of 2014 alone, almost 6.2 million computers in China were hijacked and controlled from foreign IP addresses, with more than 2.6 million of them controlled from IP addresses in the United States, and 2.4 million controlled from IP addresses in Portugal, according to CNERT, China's top Internet coordination center, according to the report.
