Recently, according to the Cncert sampling monitoring results and national information security vulnerability Sharing Platform (CNVD) published data, from July 18 to July 24, China's Internet network Security index overall evaluation as good.

Among them, the number of hosts infected with network virus in the country is about 650,000, a sharp reduction of 45% per cent from last week; The new network virus family 2, with the new number of last week is equal to the number of government sites tampered with 57, compared to the last week 55 increased 2, new information security vulnerabilities 125, increase by 25%, There are 37 high-risk vulnerabilities, equal to the number of last week.

Below, IDC comments the network with everybody concerns in the period from July 18 to July 24, our country Internet network security condition:

I. Network virus activity

The number of hosts infected with the network virus in the territory is about 650,000, a sharp drop of 45% from last week's chain. Among them, the territory by the Trojan or zombie program control of about 89,000, the chain significantly increased by 57%, more than in recent weeks has also increased significantly; the domestic infection of the Conficker worm host about 560,000, the chain significantly down 50%.

(1) According to the China Anti-Network Virus Alliance (ANVA) organized the release of active network virus to learn that the use of web-horse, software fake and bundled download to spread the proportion of network viruses, viruses are 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 18-July 24 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, with the new number of the same last week, the number of new network virus family is 2, with the new number of last week is equal. 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 the Cncert monitoring data, during the statistical period, the number of tampered sites in the territory was 775, with a slight increase of 0.25% 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 57 (occupies the Territory 7%), the chain growth about 4%.

Summary: In the period from July 18 to July 24, 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.
