Explanation :

Virus:Win32/Sality.T is a file infector that targets files with extensions .SCR or .EXE. This virus may execute a damaging payload that deletes files with certain extensions and terminates security-related processes and services. InstallationUpon execution, Virus:Win32/Sality.T drops its malicious code as the following files:  wmdrtc32.dll wmdrtc32.dl_ Note - refers to a variable location that is determined by the malware by querying the Operating System. The default installation location for the System folder for Windows 2000 and NT is C:WinntSystem32; and for XP and Vista is C:WindowsSystem32. It then creates the mutex "_kuku_joker_v4.00" to prevent more than one instance of itself running in memory at one time. Spreads Via... Infecting FilesVirus:Win32/Sality.T targets all files in drive C:, beginning with the root folder, that have file extensions of either .EXE or .SCR. It infects found files by adding a new code section to the host and inserting its malicious code into this newly added section.

Downloads FilesThis virus may connect to remote websites to download and execute additional and possibly malicious programs. It checks for Internet access by attempting a connection with the domain www.microsoft.com. If a successful connection is made, Win32/Sality.T may connect to pages within the website "kukutrustnet666.info" and attempt to download files. Downloaded files are saved and run in the %TEMP% folder.  Analysis by Francis Allan Tan Seng
