JAKARTA - Virus.Win32.Sality.aa and Packed.Win32.Krap.b the top during the month of November, remain in the position in December as the virus flare thwart the computer world. Overall, the ranking does not change the composition dramatically.
This statement was delivered through a monthly report in December this Kaspersky, Tuesday (6/1/2009). New month, Mabezat.b worms and AutoRun.eee, both ranking third increase in December. This reflects the effective or not with what they spread through portable devices, and to use the classic method of distribution of resources through the network divided. Mabezat.b can also menginfeksi files. Sality.aa virus used as a similar approach to this and help him ascend to the top ranking. Now mabezat.b use the same tricks.
Virus.Win32.Alman.b make an interesting hikes ranking of 10 this month. Alman from the default is to steal passwords for various online games. Considering the events that culminate gamer during the winter months, increased dramatically this very easily described. Akanlah very interesting to see what happens to the position of this dangerous program in the next months.
Two newcomers, Trojan.HTML.Agent.ai and Trojan-Downlder.JS.Agent.czm, is a pen-download any posts that do not have a general and specific features of interest.
The high percentage of malicious program recently written language Autolt writing. This is because the language is mastered easily, making it easy to create new programs. A sharp increase on the table by Trojan.Win32.Autolt.ci and the emergence of new Worm.Win32.Autolt.ar in December to confirm this development. As Mabezat.b and AutoRun.eee, Autolt.ar spread through portable devices.
The presence of two dangerous programs that represent a family of malware is not the standard in the ranking of 20 - Trojan-Downloader.WMA.GetCodec - also interesting. One of them appeared in 20 for the first time last month, directly to the rank 3, although in December shaky. Only that, Trojan-Downloader.WMA.GetCodec.r, sebuh program is interesting. Play a multimedia file that will result in an infected file downloaded - this file is P2p-Worm.Win32.Nugg.w, generally tersaji as a codec. When executed, it downloads several files containing multimedia files from the Internet. This file is different from the P2P-Worm.Win32.Nugg, while multimedia files infected by Trojan-variants Downloader.WMA.GetCodec different. Worm rename these files with "RELOADED.zip keygen", "(hot remix). Mp3" and other names that can attract users and make them be on the network peer-to-peer Gnutella.
Unexpectedly, the user and then download the files, the code continues to spread dangerous. This brings us to a conclusion that even multimedia files are not always reliable, and users who pushed for the "download a codec" should be vigilant.
All programs malware, adware and unwanted programs from this ranking can be parsed into several main categories of threat detected by Kaspersky Lab. Percentage did not change significantly compared to the month of November. Programs that can be dangerous bereplikasi stand on its own 45 percent, indicating the fear that such programs become more prevalent.
