Trojan.Otinet

Trojan.Otinet is a Trojan horse program that uses the Microsoft Windows LSASS Buffer Overrun Vulnerability (described in Microsoft Security Bulletin MS04-11) to force other computers to download a malicious program.

Type: Trojan Horse
Infection Length: 45,056 bytes

Systems Affected: Windows 2000, Windows Server 2003, Windows XP
Systems Not Affected: DOS, Linux, UNIX

Damage

When Trojan.Otinet runs, it does the following:

Generates IP addresses that are the same as that of the infected computer, except for the last octet. The last octet is generated in sequential order starting from 1 through to 255.

Attempts to connect to the generated IP addresses on TCP port 445 using the Microsoft Windows LSASS Buffer Overrun Vulnerability (described in Microsoft Security Bulletin MS04-011).

If a connection is made, the Trojan sends shell code to the remote computer. The shell code may cause the remote computer to download a malicious program from the predetermined IP address 67.18.129.78.

Currently, the IP address uses a Download.Trojan that downloads a Trojan.Horse. The Trojan.Horse then downloads the following malicious codes:

Trojan.Otinet
Three Dialer.Targets

Deletes itself from the infected computer.

Removal Instructions

The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

Disable System Restore (Windows Me/XP).
Update the virus definitions.
Run a full system scan and delete all the files detected as Trojan.Otinet, Download.Trojan, Trojan.Horse, and Dialer.Target.

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]
Variants: VBS.Gaggle.B@mm, VBS.Gaggle.C, VBS.Gaggle.D
Type: Worm
Infection Length: Varies, about 260k, 30,721 bytes, 17,409 bytes

Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP
Systems Not Affected: DOS, Linux, Macintosh, Macintosh OS X, Novell Netware, OS/2, UNIX

Damage

Payload Trigger: n/a
Payload: n/a
Large scale e-mailing: Sends itself to all the email addresses that it collects from the local system.
Deletes files: n/a
Modifies files: Overwrites .vbs, .vbe, .js, .jse, .hta, .htm, .html, .php, .shtm, .shtml, .phtm, .phtml, .mht, .mhtml, .plg, and .htx files with itself.
Degrades performance: n/a
Causes system instability: n/a
Releases confidential info: n/a
Compromises security settings: n/a
Distribution

Subject of email: Varies
Name of attachment: Filezip.zip
Size of attachment: n/a
Time stamp of attachment: n/a
Ports: n/a
Shared drives: Generates random IP addresses and attempts to copy itself to those IP addresses. Spreads through various file-sharing networks.
Target of infection: n/a

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.

Generates random IP addresses and attempts to connect to the IP addresses using the following user names and passwords:

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.

When W32.Beagle.AC@mm runs, it performs the following actions:

Deletes any values that contain the following strings:

"My AV"
"Zone Labs Client Ex"
"9XHtProtect"
"Antivirus"
"Special Firewall Service"
"service"
"Tiny AV"
"ICQNet"

"MsInfo"
"SysMonXP"
"EasyAV"
"PandaAVEngine"
"Norton Antivirus AV"
"KasperskyAVEng"
"SkynetsRevenge"
"ICQ Net"

from the keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Creates the following files:

%System%\sys_xp.exe
%System%\sys_xp.exeopen (A copy of the worm with randomly appended data.)
%System%\sys_xp.exeopenopen (A copy of the worm with randomly appended data.)

Note: %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).

Adds the value:

"key" = "%System%\sys_xp.exe"

to the registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

so that the worm runs when Windows starts.

Opens a backdoor on TCP port 1080, which allows the infected computer to be used as an email relay.

Contacts a .php script at a number of predetermined domains. Refer to "Domains" near the end of the "Technical Details" section for a full list of the domains.

Ends processes associated with various software. Refer to "Processes" at the end of the "Technical Details" section for a full list of process names.

W32.Gaobot.AZT
Discovered on: July 18, 2004
Last Updated on: July 19, 2004 03:43:59 PM

W32.Gaobot.AZT is repacked variant of W32.Gaobot.WO. It attempts to spread through network shares that have weak passwords. It also allows attackers to access an infected computer through a predetermined IRC channel.

The worm uses multiple vulnerabilities to spread, including:

The DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026) using TCP port 135.
The RPC locator vulnerability (described in Microsoft Security Bulletin MS03-001) using TCP port 445.
The WebDav vulnerability (described in Microsoft Security Bulletin MS03-007) using TCP port 80.
The Workstation service buffer overrun vulnerability (described in Microsoft Security Bulletin MS03-049) using TCP port 445.

W32.Gaobot.AZT is packed with FSG (MEW), ASPack, and UPX.

Type: Worm
Infection Length: 159,823 bytes

Systems Affected: Windows 2000, Windows NT, Windows XP
Systems Not Affected: DOS, Linux, Macintosh, UNIX, Windows 3.x, Windows CE

Damage

Payload Trigger: n/a
Payload: n/a
Large scale e-mailing: n/a
Deletes files: n/a
Modifies files: n/a
Degrades performance: n/a
Causes system instability: n/a
Releases confidential info: n/a
Compromises security settings: Terminates processes associated with security software. Allows unauthorized remote access.
Distribution

Subject of email: n/a
Name of attachment: n/a
Size of attachment: n/a
Time stamp of attachment: n/a
Ports: TCP 80, 135, 445
Shared drives: Attempts to copy itself to admin$; ipc$, c$; d$ and e$
Target of infection: Utilizes a range of exploits to propagate.

When W32.Gaobot.AZT is executed, it performs the following actions:

Copies and executes itself as %System%\videons32.exe.

--------------------------------------------------------------------------------
Note: %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).

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

Adds the value:

"Windows Video Drivers" = "videons32.exe"

to the registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
RunServices

so that the worm runs when you start Windows.

Ends the processes that are associated with antivirus and firewall software. Refer to "Processes" at the end of this section for a list of the process names.

Attempts to end the following processes, which are associated with other worms:
taskmon.exe
bbeagle.exe
d3dupdate.exe
winsys.exe
ssate.exe
i11r54n4.exe
rate.exe
irun4.exe
Ssate.exe

Appends the following lines to the infected computer's hosts file:

127.0.0.1 www.trendmicro.com
127.0.0.1 trendmicro.com
127.0.0.1 rads.mcafee.com

127.0.0.1 www.symantec.com

Connects to a predetermined IRC channel, using its own IRC client, and listens for commands.

The worm can:

Take a screenshot of the system
Change the IRC server to which the worm connects
Force a connection to a specified IRC channel
Terminate the worm
Have the worm send messages to people or channels on IRC
Instruct the worm to send files from the system to the specified user over IRC (DCC Send)
Download and execute files
Steal system information
Harvest email addresses
Steal CD keys for various games
Connect to FTP servers to upload files
Terminate processes (other than those mentioned in step 4)
Connect to other systems using SSH
Run the worm as a SOCKS proxy server and make connections. These connections will then appear to have come from an infected computer instead of the attacker.

Attempts to spread to other computers by exploiting the following vulnerabilities:

The DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026) using TCP port 135
The RPC locator vulnerability (described in Microsoft Security Bulletin MS03-001) using TCP port 445
The WebDav vulnerability (described in Microsoft Security Bulletin MS03-007) using TCP port 80
The Workstation service buffer overrun vulnerability (described in Microsoft Security Bulletin MS03-049) using TCP port 445

Uses various user names and weak passwords. It also uses the user names found using NetUserEnum() to probe these shares:

admin$
ipc$
c$
d$
e$

Copies itself to any computers it compromised using the previously mentioned exploits.

If you go to www.paypal.com, the worm tries to steal PayPal login information by logging keystrokes.

If instructed by an attacker, the worm can steal login information for several AOL services, including the AOL Instant Messenger service

W32.Mydoom.L@mm
Discovered on: July 19, 2004
Last Updated on: July 20, 2004 10:43:34 AM

The W32.Mydoom.L@mm mass-mailing worm:

Uses its own SMTP engine to send itself to all the email addresses that it finds from an infected system.
The email has an attachment with a .bat, .cmd, .com, .exe, .pif, or .scr extension.
Contains keylogging capabilities. The From field of the email is spoofed.
Acts as a backdoor on infected systems.
Is written in C++ and is packed with UPX.

Note: Virus definitions 60719am (extended version July 19, 2004, rev. 39) and earlier, released on July 19, 2004, detect this threat as W32.Beagle.AF@mm.

Also Known As: W32/Mydoom.n@MM [McAfee], WORM_MYDOOM.L [Trend], W32/MyDoom-N [Sophos]

Type: Worm
Infection Length: 21,000 bytes

Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP
Systems Not Affected: DOS, Linux, Macintosh, Novell Netware, OS/2, UNIX, Windows 3.x

Name of attachment: Varies with a .bat, .cmd, .com, .exe, .pif, or .scr extension.
Size of attachment: 21,000 bytes
Time stamp of attachment: n/a
Ports: TCP 1042
Shared drives: Attempts to copy itself to all the folders whose names contain the following strings: incoming, ftproot, download, shar, USERPROFILE, yahoo.com.
Target of infection: n/a

When W32.Mydoom.L@mm is run, it does the following:

Copies itself as %Windows%\lsass.exe.

Note: %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).

Use a randomly named .txt file in %Temp% for logging purposes.

Note: %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).

Adds the value:

"Traybar" = "%Windows%\lsass.exe"

to the registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

so that the worm runs when you start Windows.

Creates the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\POSIX

Attempts to copy itself to all the folders whose names contain the following strings:

incoming
ftproot
download
shar

The files dropped to these folders will have the following names:

index
Kazaa Lite
Harry Potter
ICQ 4 Lite
WinRAR.v.3.2.and.key
Winamp 5.0 (en) Crack
Winamp 5.0 (en)

with one of the following extensions:

exe
com
ShareReactor.com
scr

Opens a backdoor on TCP port 1042.

Gathers email addresses from the files with the following extensions on a compromised system:

doc
txt
htm
html

Uses its own SMTP engine to send itself to the email addresses that it finds. The email message that the worm constructed typically has the following properties:

From: Spoofed.

Subject: May be one of the following:

say helo to my litl friend
click me baby, one more time

W32.Beagle.AG@mm
Discovered on: July 19, 2004
Last Updated on: July 20, 2004 05:24:57 PM

W32.Beagle.AG@mm is a mass-mailing worm that uses its own SMTP engine to spread through email and opens a backdoor on TCP port 1080.

The subject line, body, and attachment name of the email vary. The attachment will have a .com, .cpl, .exe, .scr, or .zip file extension. If the file attachment is a .zip file, it will be password protected.

The worm is packed with PeX.

Symantec Security Response has developed a removal tool to clean the infections of W32.Beagle.AG@mm.

from the keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Creates the following files:

%System%\winxp.exe
%System%\winxp.exeopen
%System%\winxp.exeopenopen
%System%\winxp.exeopenopenopen
%System%\winxp.exeopenopenopenopen

Note: %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).

Drops the file, %System%\winxp.exeopenopen, which will be a .zip file or .cpl file:

If the file is a .zip file, it will contain two randomly named files. One will be a .exe file and the other will be a text file with a .sys, .dat, .idx, .vxd, .vid, or .dll extension.
If the file is a .cpl file and is executed, it will drop a file named cjector.exe into the %Windir% folder.

Note: %Windir% is a variable. The worm locates the Windows installation folder (by default, this is C:\Windows or C:\Winnt) and copies itself to that location.

Adds the value:

"key" = "%System%\winxp.exe"

to the registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

so that the worm runs when Windows starts.

Opens a backdoor on TCP port 1080, which allows the infected computer to be used as an email relay.

Contacts a .php script at a number of predetermined domains. Refer to "Domains" near the end of the "Technical Details" section for a full list of the domains.

Ends the processes associated with various software. Refer to "Processes" at the end of the "Technical Details" section for a full list of process names.

If the system date is after May 5, 2006, the worm will exit from memory and delete its registry value and the key:

HKEY_CURRENT_USER\SOFTWARE\base_path

Attempts to create copies of itself in any folder that contains the characters "shar." The files will have the following file names:

ACDSee 9.exe
Adobe Photoshop 9 full.exe
Ahead Nero 7.exe
Kaspersky Antivirus 5.0
KAV 5.0

Removal using the W32.Beagle@mm Removal Tool

Symantec Security Response has developed a removal tool to clean the infections of W32.Beagle.AG@mm. Use this removal tool first, as it is the easiest way to remove this threat.

Manual Removal
The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

Disable System Restore (Windows Me/XP).
Update the virus definitions.
Restart the computer in Safe mode or VGA mode.
Run a full system scan and delete all the files detected as W32.Beagle.AG@mm.
Delete the value that was added to the registry.

To delete the value from the registry

Type regedit

Then click OK.

Navigate to the key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

In the right pane, delete the value:

"key" = "%System%\winxp.exe"

Exit the Registry Editor.

[b]Obtaining and running the tool[/b]

--------------------------------------------------------------------------------
Note: You must have administrative rights to run this tool on Windows NT 4.0, Windows 2000, or Windows XP.

[b]Download the FxBeagle.exe file from: [url=\"http://securityresponse.symantec.com/avcenter/FxBeagle.exe\"]http://securityresponse.symantec.com/avcenter/FxBeagle.exe[/url]. [/b]

Save the file to a convenient location, such as your downloads folder or the Windows desktop, or removable media known to be uninfected.
To check the authenticity of the digital signature, refer to the "Digital signature" section later in this writeup.
Close all the running programs before running the tool.
If you are on a network or if you have a full-time connection to the Internet, disconnect the computer from the network and the Internet.
If you are running Windows Me or XP, then disable System Restore. Refer to the "System Restore option in Windows Me/XP" section later in this writeup for further details.

Caution: If you are running Windows Me/XP, we strongly recommend that you do not skip this step.

Double-click the FxBeagle.exe file to start the removal tool.
Click Start to begin the process, and then allow the tool to run.
Restart the computer.
Run the removal tool again to ensure that the system is clean.
If you are running Windows Me/XP, then reenable System Restore.
Run LiveUpdate to make sure that you are using the most current virus definitions.

Note: The removal procedure may not be successful if Windows Me/XP System Restore is not disabled as previously directed, because Windows prevents outside programs from modifying System Restore.

When the tool has finished running, you will see a message indicating whether the computer was infected by W32.Beagle@mm. In the case of a removal of the worm, the program displays the following results:
Total number of the scanned files
Number of deleted files
Number of repaired files
Number of terminated viral processes
Number of fixed registry entries

Digital signature
FxBeagle.exe is digitally signed. Symantec recommends that you use only copies of FxBeagle.exe, which have been directly downloaded from the Symantec Security Response Web site. To check the authenticity of the digital signature, follow these steps:
Go to [url=\"http://www.wmsoftware.com/free.htm\"]http://www.wmsoftware.com/free.htm[/url].
Download and save the chktrust.exe file to the same folder in which you saved FxBeagle.exe (for example, C:\Downloads).
Depending on your operating system, do one of the following:
Click Start, point to Programs, and then click MS-DOS Prompt.
Click Start, point to Programs, click Accessories, and then click Command Prompt.

Change to the folder in which FxBeagle.exe and Chktrust.exe are stored, and then type: chktrust -i FxBeagle.exe.

For example, if you saved the file to the C:\Downloads folder, you would enter the following commands:

cd\
cd downloads
chktrust -i FxBeagle.exe

Press Enter after typing each command. If the digital signature is valid, you will see the following:

"Do you want to install and run "W32.Beagle Removal Tool" signed on 07/19/2004 4:24 PM and distributed by Symantec Corporation?"

W32.Agist.A@mm
Discovered on: July 18, 2004
Last Updated on: July 20, 2004 11:00:09 AM

The W32.Agist.A@mm mass-mailing worm:

Scans fixed and RAM drives.
Scans drives C through Z for email addresses and sends itself to any email addresses found.
The subject, body, and attachment names vary.
The attachment will have a .zip file extension. The worm is packed using FSG.

Also Known As: I-Worm.Agist.a

Type: Worm
Infection Length: 14,245 bytes

Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows XP
Systems Not Affected: DOS, Linux, Macintosh, Novell Netware, OS/2, UNIX, Windows 3.x

Large scale e-mailing: Sends email to the addresses collected from an infected computer.
Deletes files: n/a
Modifies files: n/a
Degrades performance: Mass-mailing may clog mail servers or degrade network performance.
Causes system instability: n/a

Name of attachment: Varies with .zip file extension
Size of attachment: 14,245 bytes
Time stamp of attachment: n/a
Ports: n/a
Shared drives: n/a
Target of infection: n/a

When W32.Agist.A@mm runs, it performs the following actions:

Creates a mutex with the same name as the currently logged on user.

Copies itself to %system%\<filename>.exe.

The file name will have four letters, generated as follows:

First letter: last letter of the currently logged on user name
Second letter: last letter of the computer name
Third letter: First letter of the user name
Fourth letter: First letter of the computer name

Note: %Windir% is a variable. The worm locates the Windows installation folder (by default, this is C:\Windows or C:\Winnt) and copies itself to that location.

If the infected computer runs Windows 95/98/Me, the worm will add:

load=<worm filename>.exe

to the [windows] section in the Win.ini file.

Gathers the email addresses from drives C to Z. It checks only fixed drives and RAM disks. In each drive, it searches for the email addresses in the files with the following extensions:

adb
tbb
html
xml
cfg
vbs
msg
dbx
uin
jsp
asp
cgi
php
sht
mht
ods
log
htm
mbx
nch
eml
txt

Uses its own SMTP engine to send an email to the gathered email addresses.

The email will have the following properties:

From: <spoofed>

Subject: (blank, or one of the following)
Against!
Revenge!

Body: (garbage)
The email will have an attached randomly named .zip file. This .zip file contains a copy of the worm.

Disable System Restore (Windows Me/XP).
Update the virus definitions.
Edit the changes made to the Win.ini file:

To Edit the Win.ini file
If you are running Windows 95/98/Me, the function you perform depends on your operating system, follow these steps:
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:

edit c:\windows\win.ini

and then click OK.

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:

load= %system%\<worm filename>.exe

If this line exists, delete everything to the right of run=

Restart the computer in Safe mode or VGA mode.

Run a full system scan and repair the files that are detected as W32.Agist.A@mm.

Click Repair. If the repair fails, the file must be one of the dropped files. Delete the file.

Restart the computer in Normal mode.

W32/Sdbot-KK
Win32 worm

W32/Sdbot-KK is a worm which attempts to spread to remote shares which have weak passwords. The worm also allows unauthorised remote access to the computer via IRC channels.
W32/Sdbot-KK copies itself to the Windows system folder as VIDEONS32.EXE and creates entries in the registry in the following locations to run itself on system restart:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Microsoft Video Drivers = videons32.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Video Drivers = videons32.exe

This worm will search for shared folders on the internet with weak passwords and copy itself into them. A text file named HOSTS may also be dropped into C:\<Windows System32>vers\etc which may contain a list of anti-virus and other security-related websites each bound to the IP loopback address of 127.0.0.1 which would effectively prevent access to these sites.
For example:

127.0.0.1 www.symantec.com
127.0.0.1 securityresponse.symantec.com
127.0.0.1 symantec.com
127.0.0.1 www.sophos.com
127.0.0.1 sophos.com

Creates the following files:

%System%\FUKULAMER.exe.
%System%\FUKULAMER.exeopen, which is a copy of the worm with randomly appended data.
%System%\FUKULAMER.exeopenopenopen, which is a .jpeg or .gif file if the file, Gdiplus.dll, is present on the computer. Otherwise it will be a .bmp file.
%System%\FUKULAMER.exeopenopenopenopen, which is not viral by itself.

Note: %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).

If the file is a .zip file, it will contain two randomly named files. One will be a .exe file and the other will be a text file with a .ini, .cfg, .txt, .vxd, .def, or .dll extension.
If the file is a .vbs file and is executed, it will drop a file named vss_2.exe into the current folder.
If the file is a .cpl file and is executed, it will drop a file named cplstub.exe into the %Windir% folder.
If the file is a .hta file and is executed, it will drop a file named qwrk.exe into the current folder.

Adds the value:

"reg_key" = "%System%\FUKULAMER.exe"

to the registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

If the system date is after January 25, 2005, the worm will exit from memory and delete its registry value, as well as the key:

HKEY_CURRENT_USER\SOFTWARE\base_reg_path

Opens a backdoor on TCP port 1234, which allows the infected computer to be used as an email relay.

Attempts to create copies of itself in any folder that contains the characters "shar."

The files will have the following file names:
