A report by the National Computer Network Emergency Response Coordination Center of China says the Asian country has become the world's biggest victim of cyber attacks.

The report adds that 8.9 million domestic computers in china were attacked and controlled by 47,000 overseas Internet Protocol (IP) addresses last year.

Attacks include server destruction, website content distortion and theft of personal data from Chinese Internet users. In one of the attacks hackers changed the content of over one thousand Chinese websites, including more than 400 run by government agencies.

“China’s economic, political and military information becomes more interesting to its overseas counterparts and has attracted more hackers,” Wang Fengwei of the Shanghai Cenlaw and Partners Law Firm told Press TV.

Computer experts say most of the IP addresses of the attackers originated in Japan, the United States and the Republic of Korea.

“Japan and Korea are close neighbors of China with strong political, economic and military links with us; and the US has interest in different countries,” Fengwei added.

Most hackers have reportedly used Trojan Horse-style programs to steal personal data. They have also intended to access state networks and steal confidential information.

Experts believe the Chinese cyber defense is not efficient despite the fact that the government has been so prudent about the internet content and there are even Internet “police” supervising it.
