Iframe software keeps 'champion' on malicious

Sophos, the world's leading IT security company, has announced a list of the most popular malware (malware) in May 2007, which is causing trouble for computer users around the world.

The company concluded that infected websites are still a major 'threat' affecting other sites, including official government websites.

Compared to April, the number of infected websites on average has increased by 1,000 pages per day, which means that in May, there are 9,500 pages newly infected in May each month. .

In the May malware list, the iframe is still in the 'champion' position. Up to 65.5% of infected websites have this malicious code. This month's list adds three new viruses that regularly infect HTM, HTML and HTT files.

Surprisingly, these viruses are quite "old" faces, especially the Soraci virus - which has been taken care of by Sophos for over a year. The other two viruses on this list are Redlof and Roor.

In addition to the three viruses mentioned above, the list also contains the names of four trojans located in TopTen. However, the fact that iframe continues to "dominate" this ranking is the most notable point obtained from Sophos statistics.

No significant changes have been made to the list of countries that owned malware-infected sites in May, except for Thailand's first 'presence' and took fifth place. Sophos was surprised. When it was discovered that many of the country's "harmful" websites were government.

Meanwhile, China is still the leading country on the list when it owns more than 50% of infected sites, mainly due to the raging of iframe on its websites.

' Every month, widespread web attacks become more frequent and more difficult to deal with for businesses ', Carole Theriault, Sophos' senior security advisor, came up with conclusions about This list.
