Technical Details

The trojan downloader's file is 13824 bytes long PE executable. It has not been packed by any executable compressor.

The files are stored into the following locations:

%TEMP%/mute[randomnumber].exe  %TEMP%/volume[randomnumber].exe  %TEMP%/bass[randomnumber].exe   

For example:

C:\Documents and Settings\user\Local Settings\Temp\mute41.exe
