VBS.Gaggle.E@mm
Discovered on: July 08, 2004
Last Updated on: July 16, 2004 03:09:45 PM
VBS.Gaggle.E is a variant of VBS.Gaggle.D. It is a mass-mailing worm that overwrites several files. This worm can infect the following file types:
.vbs
.vbe
.js
.jse
.hta
.htm
.html
.php
.shtm
.shtml
.phtm
.phtml
.mht
.mhtml
.plg
.htx
The worm retrieves the email addresses from the files that have .hta, .htm, .html, .php, .shtm, .shtml, .phtm, .phtml, .mht, .mhtml, .plg, or .htx extensions. Then, it uses its own SMTP engine to send email to all the email addresses that it finds. The worm can also spread through ICQ, and some file-sharing networks.
The From field of the email is spoofed, the subject line and message vary, and the attachment is Filezip.zip.
Also Known As: I-Worm.Gedza [Kaspersky], VBS/Gedza.A [F-Prot]

When VBS.Gaggle.E runs, it does the following:
Creates copies of itself in the %System% folder as some of these file names:
File.vbs
Gedzac.vbs
hta.vbs
Israfel.vbs
pubprn.vbs
Kernel32.win
Mouse_configurator.win
Winmgd.win
Backup.vbs
Template.htm (A .html file containing the worm.)
Filezip.zip (A .zip archive of the worm.)
Notes:
%System% is a variable. The worm locates the System folder and copies itself to that location. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
The worm may insert some garbage data into the files, so that the size of the files vary.
Creates the following files in the %System% folder:
Regsrv.exe: 17,409 bytes. Detected as Trojan.KillAV.
Sendi.exe: 30,721 bytes. A component of the worm.
Pkzip.exe: A legitimate program.
AvrilLavigne.jpg: 12,549 bytes. A .jpg file.
C:\Estigma.hta: 354 bytes. A harmless .html file.
iwn.dat
iw.dat.
ixn.dat
ix.dat
Note: The worm attempts to use the .dat files to infect the Microsoft Word and Excel files.
Adds the values:
"Kernel32"="%System%\Kernel32.win"
"Israfel"="%System%\Israfel.vbs"
to the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
so that the worm runs when you start Windows.
Modifies the default value to:
"(Default)"="GEDZAC"
in the registry keys:
HKEY_CLASSES_ROOT\regfile\shell\open\command
HKEY_CLASSES_ROOT\keyfile\shell\open\command
Modifies the value to:
"Timeout"="0"
in the registry keys:
HKEY_CURRENT_USER\Software\Microsoft\Windows Scripting Host\Settings
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows Scripting Host\Settings
Modifies the value to:
"DisableRegistryTools"="1"
in the registry keys:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Policies\System
HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\
Policies\System
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
Policies\System
Copies %comshell% to all the hard drives as \inetpub\scripts\israfel.exe.
Note: %Comshell% is a variable. The worm locates the default command shell. For example, this can be command.com or cmd.exe.
Creates an iisroot.asp file in the \inetpub\wwwroot folder and its subfolders. This file is not viral by itself.
Modifies the following line to the [boot] section of the System.ini file:
shell=Explorer.exe %System%\winmgd.win
so that the worm runs when you start Windows 95/98/Me.
Modifies the following line to the [windows] section of the Win.ini file:
run=%System%\mouse_configurator.win
so that the worm runs when you start Windows 95/98/Me.
If the date of the system clock is the third day of the month, the .html file, C:\Estigma.hta, will be displayed. This file only contains text.
If the date of the system clock is the 19th day of the month, the following message will be displayed:
19/12/2003 - Saludos a Cienciano Campeon 2003 de la Copa Sudamericana
If the date of the system clock is the 11th day of the month, the following message will be displayed:
Luego del alevoso ataque de eeuu y sus aliados
contra Iraq, aun tiene bush el descaro de decir
que lo hizo por libertar al pueblo o por la
democracia, como si eso le interesara, solo le
interesa tener gobiernos titeres y el petroleo
(investiguen sobre su dizque reconstruccion
de Iraq), desde los 90 que se pretendia derrocar
al gobierno de Iraq, quien le dio el derecho de decidir que
gobiernos deben ser derrocados o no, acaso
se cree el policia del mundo, una de las frases
favoritas del Asesino de bush, es el 'origen
del mal' el es eso.
Y para terminar otra de sus frases 'que Dios bendiga a los eeuu' ojala lo haga
porque lo van a nesecitar, porque algun
dia eeuu pagara por querer decirle al
mundo como tiene que vivir
(Mensage en contra del Gobierno de eeuu, no del pueblo)"
If the date of the system clock is the 26th day of the month, the following message will be displayed:
"Soy una ballena de color azúl mi espalda sopla y tu ves esa fuente
de agua limpia aún. Nuestra casa abierta, era el ancho mar
Viajábamos en paz, sin manchas de petróleo que evitar
Busco un sitio puro donde descansar no hay muchas como yo
me tengo que cuidar de ti. Nubes blancas, cielo transparente
y el humano compartiendo con otros, un sueño que quizás ya no regrese
pues ya es tarde para todos nosotros
Soy el cóndor majestuoso del Perú, mi cuello gira y tú
me miras con ojos de luz. Busco un sitio alto donde recordar
que hubo un tiempo mejor, pues como yo no quedan más
Si tus hijos te preguntan cómo fui, no sé que les dirás, me tuve que alejar de ti
Cordilleras blancas dominando, todo ser que se alimenta del río
hombres en aldeas cultivando, sin decirle al campo dame lo que es mío
Estás equivocado, no sabes dónde vas
guanacos, osos panda, renos, águilas, delfines y todo lo demás
Estás equivocado no sabes dónde vas
un espíritu ronda por la selva llorando lo que fue el jaguar
bienvenido al mundo del hombre construído con detergentes y también con alquitrán
Soy una ballena de color azúl mi espalda sopla y tú
ves esa fuente de agua limpia aún
(Cancion perteneciente a 'Los Nosequien y Los Nosecuantos')
El 26 de Abril es el día de la Tierra, protegela"
If the date of the system clock is the 29th of the month, the worm will open the Web page, www.arvil-lavigne.com.

Creates the following files in the %Temp% folder:
imh.dat
iml.dat
imv.dat
Notes:
%Temp% is a variable. The worm locates the temporary folder and copies itself to that location. By default, this is C:\Windows\TEMP (Windows 95/98/Me/XP) or C:\WINNT\Temp (Windows NT/2000).
These files are not viral by themselves. The worm retrieves the email addresses from the Microsoft Outlook Address Book and from the files with .hta, .htm, .html, .php, .shtm, .shtml, .phtm, .phtml, .mht, .mhtml, .plg, or .htx extensions. Then, it saves the email addresses to these files.
Overwrites the .vbs, .vbe, .js, .jse, .hta, .htm, .html, .php, .shtm, .shtml, .phtm, .phtml, .mht, .mhtml, .plg, and .htx files with itself.

Copies itself to the remote computer as autorun.vbs. Then, it overwrites the autoexec.bat file with the line:
@win \autoexec.vbs
Creates a file named wininit.ini under %Windir%. This file is not malicious by itself.
Adds the line:
run=autorun.vbs
to the [windows] section of the file, Win.ini, on the remote computer.
Overwrites all the .vbs files on drive A with itself. If it does not find any .vbs files on drive A, it will copy itself as one of the following:
A:\Israfel.vbs
A:\Document.txt.vbs
A:\Image.jpg.vbs
A:\Loreley.jpg.vbs
A:\Vigilancia.txt.vbs
Uses its email component, sendi.exe, to send itself to all the email addresses that it finds.
The worm uses the current user's SMTP server or one of the following servers to spread itself:
mx1.latinmail.com
mx1.hotmail.com
The email has the following characteristics:
From: The sender's name is randomly selected from a list that the worm carries.
Attachment: Filezip.zip
Subject: Subject line is randomly selected from the list that the worm carries.
Message: The message body is randomly selected from the list that the worm carries.
It may begin with one of the following texts:

6. To remove the text from the Windows 95/98/Me Win.ini file
If you are running Windows 95/98/Me, follow these steps:
The function you perform depends on your operating system:
Windows 95/98: Go to step B.
Windows Me: If you are running Windows Me, the Windows Me file-protection process may have made a backup copy of the Win.ini file that you need to edit. If this backup copy exists, it will be in the C:\Windows\Recent folder. Symantec recommends that you delete this file before continuing with the steps in this section. To do this:
Start Windows Explorer.
Browse to and select the C:\Windows\Recent folder.
In the right pane, select the Win.ini file and delete it. The Win.ini file will be regenerated when you save your changes to it in step F.
Click Start > Run.
Type the following, and then click OK.
edit c:\windows\win.ini
(The MS-DOS Editor opens.)
Note: If Windows is installed in a different location, make the appropriate path substitution.
In the [windows] section of the file, look for a line similar to:
run=%System%\mouse_configurator.win
If this line exists, select the text. Be sure that you do not select any other text, and then press Delete.
Click File > Save.
Click File > Exit.
7. To remove the text from the Windows 95/98/Me System.ini file
Note for Windows Me users only: Due to the file-protection process in Windows Me, a backup copy of System.ini exists in the C:\Windows\Recent folder. Symantec recommends that you delete this file before continuing with the steps in this section. To do this using Windows Explorer, go to C:\Windows\Recent, and in the right pane select the System.ini file and delete it. The System.ini file will be recreated in C:\Windows\Recent when you save your changes to System.ini in C:\Windows.
Click Start > Run.
Type the following:
edit c:\windows\System.ini
And then click OK. (The MS-DOS Editor opens.)
Note: If Windows is installed in a different location, make the appropriate path substitution.
In the [boot] section of the file, look for an entry similar to:
shell=Explorer.exe %System%\winmgd.win
If this line exists, replace it with the following text:
shell=Explorer.exe
Click File > Save.
Click File > Exit.
This completes the removal. Restart the computer in Normal mode.
