China IDC report June 25: Recently, according to Cncert sampling monitoring results and national information security vulnerability Sharing Platform (CNVD) published data, from June 11 to June 17, China's Internet network Security index overall evaluation as good.

Among them, the number of hosts infected with network virus in the territory of about 1.716 million, compared to last week, decreased by about 17.4%, no new network virus family, the number of government sites tampered with 39, compared to last week, the number of chain decreased by about 18.8%; new information security vulnerabilities 104, the chain reduced by about 1.9% But there are 44 new high-risk vulnerabilities, up 29.4% from last week's new number.

Below, IDC comments the network with everybody concerns in the period from June 11 to June 17, our country Internet network security condition:

I. Network virus activity

The number of hosts infected with the network virus in the territory is about 1.716 million, a decrease of about 17.4% from last week's chain. Among them, the territory by the Trojan or zombie program control of about 353,000, the chain down about 22%, the domestic infection of the Conficker worm host about 1.363 million, compared to last week the number of the chain rose by about 5.5%.

(1) According to the China Anti-Network Virus Alliance (ANVA) organized the release of active network virus to learn that the use of web pages to hang horses or bundled with the spread of the network virus is a high proportion of viruses still more to exploit system vulnerabilities to attack the system. In this way, we come to understand the malicious virus TOP5 active on the network:

(Figure 1) June 11-June 17 malicious viruses active on the network TOP5

(2) on the network virus capture, Cncert captured a large number of new network virus files, which by the name of the network virus added 108, a significant increase in the number of new last week about 52.1%; According to the Network virus family statistics no new. Below, we take a look at the top ten Cncert detection of active horse site domain name, active put horse site IP.

(3) in the network of virus transmission, cncert monitoring found in the horse site, through the domain name access to a total of 440 domain names, direct access through IP a total of 129 IP. In 440 of the site domain name, registered in the territory of the number of domain names for 100 (about 22.7%), the number of domain names registered abroad 331 (about 75.2%), unknown registrar of the domestic and foreign information of 9 (about 2.1%). The following figure is the distribution of these site names by the top-level domain, the top three is. com (about 50.5%),. info (about 18.6%),. cn (about 7.7%).

In addition, the communications industry, the member units of the Internet communication to Cncert 105 malicious domain name or IP (after the heavy), the units submitted to the number of statistics as shown in the following figure.

II. website Security

According to Cncert monitoring data, the number of sites tampered with in the territory this week was 321, down about 15.3% from last week's number. The number of tampered sites in the territory by type distribution as shown in the following figure, the largest number is still. com and. com.cn Domain name Web site. Among them, the gov.cn domain name class website has 39 (occupies the territory 12.1%), compared to last week the chain drop about 18.8%.

Summary: In the period from June 11 to June 17, China's Internet network Security index overall evaluation as good, no harm more serious network security incidents. However, users need to pay special attention to the need to strengthen the system in a timely manner to repair and reinforce the installation of security protection software. During the internet, do not easily open the network of unknown sources of pictures, music, video and other documents, do not download and install some unknown software, especially some so-called plug-in programs to prevent network virus infection.
