W32/Yaha.U (Yaha.T). Envío masivo de correo infectado
 
VSantivirus No. 1084 Año 7, Jueves 26 de junio de 2003

W32/Yaha.U (Yaha.T). Envío masivo de correo infectado
http://www.vsantivirus.com/yaha-u.htm

Nombre: W32/Yaha.U
Tipo: Gusano de Internet
Alias: W32.Yaha.T@mm, I-Worm.Lentis.gen, W32/Yaha.t@MM, W32/Yaha-T
Fecha: 25/jun/03
Plataforma: Windows 32-bit
Tamaño: 51,424 bytes

Gusano de Internet programado en Visual C++ y comprimido con la utilidad FSG, que se propaga a través del correo electrónico a todos los contactos de la libreta de direcciones de Windows (WAB, Windows Address Book), lista de contactos de MSN Messenger y Yahoo Pager, así como a direcciones extractadas de archivos temporales y del caché de Internet (archivos HTM, HTML y HTA).

Debido a la cantidad de variantes de este gusano, y al hecho de que cada antivirus ha examinado muestras en un orden diferente a como lo han hecho otras compañías, la denominación del virus varía entre fabricantes, causando confusión entre los usuarios.

Esta descripción por lo tanto solo sirve como referencia.

El gusano utiliza su propio motor SMTP de modo que puede enviarse en mensajes infectados, sin necesidad de utilizar las facilidades de programas como Outlook, etc.

Puede finalizar procesos específicos relacionados con conocidos antivirus y cortafuegos.

También puede provocar ataques de denegación de servicio (DoS), a determinadas direcciones fijas, incluidas directamente en su código (en este caso, cinco).

Es capaz de infectar al solo leer o ver en la vista previa el mensaje que lo contenga, en aquellos sistemas que no han sido actualizados con los parches correspondientes (vulnerabilidad "Exploit IFRAME"). Esto incluye Internet Explorer 5.0 y anteriores –- no soportados por Microsoft —- e Internet Explorer 5.01 a 5.5 sin parches.

Vea al final del artículo: "Actualizar Internet Explorer"

Se propaga en mensajes creados de la siguiente manera:

El campo "De:" puede ser falsificado por el gusano, de modo que rara vez indica la dirección verdadera del usuario infectado que lo envía. Algunas de las posibles combinaciones:

De: [nombre][dirección]

El gusano obtiene las direcciones a las que se envía de la libreta de Windows (WAB), todos los contactos, caché de Messenger, Yahoo Pager, páginas Web, etc.

Cuando se ejecuta el adjunto, el gusano se copia en la carpeta System de Windows, con los siguientes nombres:

c:\windows\system\wintsk32.exe
c:\windows\system\exeldr32.exe

También se copia en "c:\windows\system\" con uno de los siguientes nombres:

Be_happy.scr
Best_friend.scr
Colour_of_life.scr
Dance.scr
Friend_finder.exe
Friend_happy.scr
Friendship.scr
Friendship_funny.scr
Funny.scr
Gc_messenger.exe
Hotmail_hack.exe
I_like_you.scr
Life.scr
Love.scr
Shake.scr
Sweet.scr
True_love.scr
World_of_friendship.scr

En todos los casos, "C:\Windows" y "C:\Windows\System" pueden variar de acuerdo al sistema operativo instalado (con esos nombres por defecto en Windows 9x/ME, como "C:\WinNT", "C:\WinNT\System32" en Windows NT/2000 y "C:\Windows\System32" en Windows XP).

Modifica el registro, para autoejecutarse en cada reinicio del sistema:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
MicrosoftServiceManager = c:\windows\system\wintsk32.exe

HKLM\Software\Microsoft\WindowsCurrentVersion\RunServices
MicrosoftServiceManager = c:\windows\system\wintsk32.exe

También modifica las siguientes claves:

HKLM\Software\Classes\exefile\shell\open\command
(Predeterminado) = c:\windows\system\exeldr32.exe "%1" %*

Esto hace que se ejecute el virus cada vez que una aplicación ejecutable es llamada por el sistema. Esto dificulta la limpieza del virus, ya que cualquier programa que se ejecute, incluido el antivirus, lanza al gusano en memoria.

"C:\windows\system\exeldr32.exe" representa el nombre y ubicación del ejecutable del gusano una vez que se instaló en nuestro PC. En principio suele ser el que se indica, pero podría ser alguno de las otras copias del gusano.

El gusano intenta acabar con la ejecución de una larga lista de programas de seguridad, como antivirus, cortafuegos, etc., matando en memoria los procesos que contengan cualquiera de las siguientes cadenas:

_avp32
_avp32.exe
_avpcc

Modificación del registro

Es necesario renombrar el archivo REGEDIT.EXE como REGEDIT.COM, ya que la extensión .EXE está asociada al gusano, y éste se volvería a cargar si ejecutamos REGEDIT en forma normal.

1. Desde Inicio, Ejecutar, teclee lo siguiente (puede usar cortar y pegar) y pulse Enter:

Command /c Rename C:\Windows\Regedit.exe Regedit.com

Si Windows no está instalado en "C:\Windows", debe cambiar esta referencia (Ej.: "C:\Nombre\Regedit.exe", etc.).

2. Desde Inicio, Ejecutar, teclee "Regedit.com" y pulse Enter

3. En el panel izquierdo del editor de registro de Windows, pinche en el signo "+" hasta abrir la siguiente rama:

HKEY_LOCAL_MACHINE
\Software
\Classes
\exefile
\shell
\open
\command

4. Pinche sobre la carpeta "command". En el panel de la derecha debería ver algo como:

(Predeterminado) = c:\windows\system\exeldr32.exe "%1" %*

5. Pinche sobre "(Predeterminado)" y en Información del valor, debe borrar el cargador: (c:\windows\system\exeldr32.exe) y dejar solo esto (comillas, porcentaje, número uno, comillas, espacio, porcentaje, asterisco):

(Predeterminado) = "%1" %*

6. En el panel izquierdo del editor, pinche en el signo "+" hasta abrir la siguiente rama:

HKEY_LOCAL_MACHINE
\SOFTWARE
\Microsoft
\Windows
\CurrentVersion
\Run

7. Pinche en la carpeta "Run" y en el panel de la derecha busque y borre la siguiente entrada:

MicrosoftServiceManager

8. Repita los pasos 6 y 7 (pinchando en "RunServices") con la siguiente rama del registro:

HKEY_LOCAL_MACHINE
\SOFTWARE
\Microsoft
\Windows
\CurrentVersion
\RunServices

9. Use "Registro", "Salir" para salir del editor y confirmar los cambios.

10. Reinicie su computadora (Inicio, Apagar el sistema, Reiniciar).
