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

Among them, the number of hosts infected with the network virus in the territory of about 1.18 million, compared to a sharp reduction of 60% in the chain last week, the number of government sites tampered with 55, a significant increase of 67% from last week's 33 chain; 4 Fewer than last week's 41. Below, IDC comments the network with everybody concerns in the period from July 11 to July 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 1.18 million, a sharp drop of 60% from last week's chain. Among them, the territory by Trojans or zombies program control of about 57,000, the chain down 3%, the domestic infection of the Conficker worm host about 1.12 million, the chain significantly down 61%.

(1) According to the China Anti-Network Virus Alliance (ANVA) organized the release of active network virus, the use of web pages to hang horses, bundled download to spread the proportion of the network virus, the virus is 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) July 11-July 17 malicious viruses active on the network TOP5

(2) in the network virus capture, cncert through a variety of channels to obtain a large number of new network virus files, including the number of new network virus 102, the chain increased by 1%, the number of new network virus families 2. Below, we look at Cncert detected the top five active horse site domain name, active put horse site IP.

(3) In the network virus in the process of transmission, often need to use hackers register a large number of domain names. In this virus detection, ANVA focus on a number of malicious domain names for network virus transmission, and statistics of active malicious domain name of the top-level domain name and the main registered domain name agencies.

II. website Security

According to Cncert monitoring data, during the statistical period, the number of sites tampered with was 773, with a significant increase of 64% in the previous week. 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. The gov.cn Domain name class website has 55 (occupies the territory 7%), the chain also greatly increases 67%.

Summary: In the period from July 11 to July 17, China's Internet network Security index overall evaluation as good, as in recent years, no more serious harm to the network security incidents. However, users still need to pay special attention to the need to strengthen the system in time to repair the loopholes 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.
