-----------------------------

Cuando el gusano se ejecuta se copia a sí mismo en:

Nota:

- %windows% representa la carpeta de instalación de Windows (Ej. C:\WINDOWS, C:\WINNT)

- %Program Files% es la carpeta por defecto donde se encuentran instaladas las aplicaciones.

 

También modifica las siguientes entradas en el registro para poder ejecutarse en cada inicio del sistema

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
"Firewall"="%Program Files%\SP2 UPDATE.exe"

 

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
"Protection"="%Program Files%\Internet Explorer\Norton Internet Security.exe"

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
"SysRes"="%Program Files%\Internet Explorer\IExpIore .exe"
 

También modifica los siguientes valores para intentar en deshabilitar los niveles de seguridad de la computadora atacada y evitar que se ejecuten las siguientes tareas como ejecutar el Administrador de Tareas, El Editor de Registro (Regedit), ejecutar programas a través de Inicio - Ejecutar y el Windows Update.

Se copia a si mismo dentro de la carpeta compartida de programas de Intercambio de archivos P2P (KaZaA, KaZaA Lite, BearShare, Edonkey2000, Grokster, KMD, Shareaza y Morpheus) con el nombre de archivo "Torrie & Stacy Nude ScreenSaver.exe"

 

Luego modifica la siguiente entrada en el registro para asegurarse que los archivos de la carpeta compartida del KaZaA estén compartidos

 

HKEY_CURRENT_USER\Software\Kazaa\LocalContent
"DisableSharing"="0"

Seguidamente copia un archivo de texto dentro de la carpeta raiz del computador con el nombre de archivo "Virus Detected.txt"

 

También modifica el archivo SCRIPT.INI del mIRC si existe en el computador atacado, agregando una entrada, de esta manera tratara de enviarse a si mismo cuando el usuario se conecte a un canal de chat.

 

También modifica las siguientes entradas en el registro

 

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion

"RegisteredOwner"="surconfluge"

 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ComputerName\ActiveComputerName

"ComputerName" = "surconfluge"

Intentará finalizar los siguientes procesos utilizando el TASKKILL

 

 

Finalmente el gusano sobrescribe el archivo HOSTS que se encuentra en %system%\drivers\etc\, para redireccionar direcciones URLs al localhost (127.0.0.1)
