Over 3,000 governmental websites were once secretly installed the “Backdoor Program” by hackers so as to maliciously take control of them, according to Network Security Report of China 2012 which declared on March 19.
The “Backdoor Program” is a network virus used by hackers to lurk inside the administrative platform of a website.
According to a surveillance report of National Computer Network Emergency Response Technical Team (CERT), about 52,324 websites have been secretly installed the “Backdoor Program” in Chinese Mainland, among which the number of governmental websites amounts to 3,016, the average monthly increase being 213.7 percent and 93.1 percent respectively since those of the same period in 2011.
Caution to amendments has successfully urged most of the governmental websites to amend their loopholes, but to a large number of medium-size and small enterprises, their loopholes remain unfixed.
Security loopholes are the major cause that made it possible for hackers to install “Backdoor Program”. In 2012 National Computer Network Emergency Response Technical Team, together with other enterprises that aim at safeguarding network security, collected and declared 6,824 loopholes, a 23 percent increase compared to that of 2011. Those largely increasing security loopholes made it difficult for network maintenance staff to handle them quickly, therefore the maintenance period of a loophole generally is prolonged.
“For example, we have cautioned the public, early in January 2012 that there was a loophole with an extremely risk in more than 300 governmental websites. But in our recheck of those websites in February 2013, still there were 20 percent of them have the loophole unfixed,” said Zhou Yonglin, head of the Operation Department of National Computer Network Response Technical Team.
Once a loophole exists, hackers can have access to a website’s administrative platform, installing the “Backdoor Programme” and stealing information of online clients’.
According to a rough estimation, over 50 databases sold personal information publicly or secretly via industry chains of black interests in 2012, nearly 50 million personal information confirmed to have been traded.
