It has been reported that this Trojan is sent through MSN Messenger as a file named "Net Echo.exe".

When PWSteal.Likmet.A is executed, it performs the following actions:

Displays a fake error message window which reads:

MSN Echo Runtime error 429 Not enough memory

Opens a backdoor on TCP port 88.

Creates a fake MSN messenger logon window when an attacker connects to this backdoor

Sends the login information that the user types into this window back to the attacker, using the back door.

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 PWSteal.Likmet.A.

If any files are detected as infected with PWSteal.Likmet.A, click Delete.

Note: If your Symantec antivirus product reports that it cannot delete an infected file, Windows may be using the file. To fix this, run the scan in Safe mode. For instructions, read the document, "How to start the computer in Safe Mode." Once you have restarted in Safe mode, run the scan again.

When all the infected files have been deleted, restart the computer in Normal mode.

Troj/Padodo-Fam

Aliases: Backdoor.AXJ, Berbew, Webber

Type: Trojan

Troj/Padodo-Fam is a family of proxy and backdoor Trojans with password
stealing funtionality.
When first run the Trojans copy themselves to the Windows system folder
with a random filename and an extension of EXE and drop a library DLL to
the system folder with a random filename and an extension of DLL.

The DLL is registered as a COM object creating registry entries similar
to the following:

HKCR\CLSID\(79FEACFF-FFCE-815E-A900-316290B5B738)
\InProcServer32\

HKCR\CLSID\(79FEACFF-FFCE-815E-A900-316290B5B738)
\InProcServer32\@ = <pathname of dropped DLL>

HKCR\CLSID\(79FEACFF-FFCE-815E-A900-316290B5B738)
\InProcServer32\ThreadingModel = "Apartment"

The following registry entry is created to load the DLL on startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\
ShellServiceObjectDelayLoad\Web Event Logger =
(79FEACFF-FFCE-815E-A900-316290B5B738)

The DLL component launches the Trojan executable which then runs
continuously in the background allowing unauthorised access and control
of the computer from a remote network location.

Log files may be created in the system folder to store stolen passwords.

The Trojans provide a proxy server on a random port which allows data to
be routed through the computer. The proxy can be used to bypass access
restrictions, to hide the IP address of the source computer and to forward
spam email.

Following installation the Trojans try to send notification messages to
remote locations with details of the computer's IP address and access
ports.

Creates the following files:

%System%\loader_name.exe
%System%\loader_name.exeopen (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).


Drops the file, %System%\loader_name.exeopenopen. This file will be a .zip file, .vbs file, .cpl file, .hta file, or the worm itself. One of the following actions will occur, depending on the file type:

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 .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.


Drops the file, %System%\loader_name.exeopenopenopen. If the file Gdiplus.dll is present on the computer, this file will be a .jpg or .gif. Otherwise it will be a .bmp file.


Adds the value:

"reg_key" = "%System%\loader_name.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:

Time stamp of attachment: n/a
Ports: TCP port 6000
Shared drives: Copies itself to network shared folders.
Target of infection: Copies itself to Kazaa shared folder.


When W32.Lovgate.AC@mm is executed, it performs the following actions:


Creates the following files:

%Windir%\CDPlay.exe
%System%\iexplore.exe
%System%\RAVMOND.exe
%System%\WinHelp.exe
%System%\Update_OB.exe
%System%\TkBellExe.exe
%System%\hxdef.exe
%System%\Kernel66.dll, which is a hidden file.

Notes:
%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.
%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).


Creates a file named CDROM.COM in the root folder of all drives, except CD-ROM drives. The file attributes are set to system, hidden, and read_only.


Creates an autorun.inf file on each drive with the lines:

[Autorun]
open="C:\cdrom.com" /StartExplorer


Creates an archive containing a copy of the worm with the following format in the root folder of all drives, unless the drive letter is A or B:

<filename>.<ext>

Where <filename> may be one of the following:
Bakeup
Tools
email

and <ext> is one of the following:
RAR
ZIP


Adds the values:

"Winhelp" = "%system%\TkBellExe.exe..."
"Hardware Profile" = "%system%\hxdef.exe..."
"Program in Windows"="%system%\IEXPLORE.exe"

to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run


Adds the values:

"COM++ System" = "exploier.exe..."
"SystemTra" = "%windows%\CDPlay.exe"

to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\runServices

which starts the worm when Windows starts.


Adds the value:

"run"="RAVMOND.exe"

to the registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows

which starts the worm when Windows starts.


Modifies the value:

(Default) = "Update_OB.exe %1..."

in the registry keys:

HKEY_CLASSES_ROOT\txtfile\shell\open\command

so that the worm will run each time a .txt file is opened.


Stops the following services:

Rising Realtime Monitor Service
Symantec AntiVirus Server
Symantec AntiVirus Client


Terminates any processes with the following strings in their names:

rising
SkyNet
Symantec
McAfee
Gate
Rfw.exe
RavMon.exe
kill
NAV
Duba
KAV


Scans all the drives on the infected computer. If the drive type is removable, mapped, or the drive type is fixed with a drive letter greater than E, it does the following:

Attempts to rename the extensions of all .exe files to .zmx.
Sets the attributes on these files to hidden and system.
Copies itself as the original file name.


Injects a process-watching procedure, as a thread, into either Explorer.exe or Taskmgr.exe. If this thread detects that the worm process has stopped, it will attempt to launch %System%\Iexplore.exe.


Listens on TCP port 6000.


Steals information from an infected computer and stores it in the file, C:\Netlog.txt. The worm then emails the stolen information to the hacker.


Determines the location of the Kazaa shared folder from the registry.


Creates a copy of itself in the Kazaa shared folder as one of the following (with a .bat, .exe, .pif, or .scr file extension):

wrar320sc

When Backdoor.Doster is executed, it performs the following actions:


Creates the file %Windir%\hosts.


Notes:
If this file already exists in this location, which is the default location of Windows 95/98/Me, the Trojan will overwrite the existing file.
%Windir% is a variable. By default, this is C:\Windows or C:\Winnt.


Locates the default Hosts file if it is not in %Windir% and overwrites it with the dropped hosts file. This causes any traffic going to the following URLs to be redirected to the local computer:

127.0.0.1 www.thehun.com

Adds the value:

"Explorer"="%System%\explorer.exe"

to the registry entry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

so that it is executed every time Windows starts.

Notes:
%System% is a variable. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
Due to bugs in the code, the Trojan does not copy the Trojan file, Explorer.exe file, to the %System% folder. If it performed this action, this Explorer.exe file would contain functionality to open a backdoor on TCP port 80.

Removal Instructions

Disable System Restore (Windows Me/XP).
Update the virus definitions.
Run a full system scan and delete all the files detected as Backdoor.Doster.
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_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run


In the right pane, delete the value:

Deletes any values that contain the following strings:

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

from the keys:

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


Creates the following files:

%System%\sysxp.exe
%System%\sysxp.exeopen (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).


Drops the file, %System%\sysxp.exeopenopen. This file 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 cplstub.exe into the %Windir% folder.

Drops the file, %System%\sysxp.exeopenopenopen. If the file Gdiplus.dll is present on the computer, this file will be a .jpg or .gif. Otherwise it will be a .bmp file.


Drops the file, %System%\sysxp.exeopenopenopenopen, which is not viral by itself.

Adds the value:

"key" = "%System%\sysxp.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_path


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

PWSteal.Refest

PWSteal.Refest is a Trojan Horse that installs itself as a BHO (Browser Helper Object) for Internet Explorer and steals online banking information when it is submitted in web forms.



Type: Trojan Horse
Infection Length: 81,920 (.exe), 45,056 (.dll)



Systems Affected: Windows 2000, Windows 64-bit (AMD64), Windows 64-bit (IA64), Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP
Systems Not Affected: DOS, EPOC, Linux, Macintosh, Macintosh OS X, Microsoft IIS, Novell Netware, OS/2, UNIX, Windows 3.x

PWSteal.Refest does the following when it is executed:

Creates a dll file in the %System% directory. This file has a random name with up to 8 lower-case characters, e.g., "abcde.dll" or "qrstuvwx.dll". The file is 45056 bytes in length.

Note: %System% is a variable. The Trojan locates the System folder and creates a dll in 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).

Installs the dll as a Browser Helper Object, so that it is loaded every time Internet Explorer starts. To do this, it creates the following registry keys:

HKEY_LOCAL_MACHINE\Software\Classes\CLSID\{<random clsid>}
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{<random clsid>}

and sets the value

(Default) = %System%\<random name>.dll

in the registry key

HKEY_LOCAL_MACHINE\Software\Classes\CLSID\{<random clsid>}\InProcServer32.

The {<random clsid>} is a random value of the form, {########-####-####-####-############}, for example, {380b99b4-5f7d-7791-b8ef-499d848499e6}.


The dll monitors outgoing https connections to the following websites:

.anz.com
.bendigobank.com.au
.citibank.com
.citibank.de
.commbank.com.au
.dab-bank.com
.deutsche-bank.de

W32.Lovgate.Y@mm
Discovered on: July 01, 2004
Last Updated on: July 14, 2004 12:03:22 PM

W32.Lovgate.Y@mm is a mass-mailing worm that also propagates through open network shares. It allows an attacker to access your computer. The email will have a variable subject and a file attachment with a .bat, .cmd, .exe, .pif, .scr, or .zip file extension.

W32.Lovgate.Y@mm spreads through the DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026) using TCP port 135.


Note: Symantec Security Response has developed a removal tool to clean the infections of W32.Lovgate.Y@mm.


Also Known As: I-Worm.Lovgate.ae [Kaspersky], W32/Lovgate.ad@MM [McAfee]

Name of attachment: Varies with .bat, .cmd, .exe, .pif, .scr, or .zip as the extension.
Size of attachment: 152,064 bytes
Time stamp of attachment: n/a
Ports: TCP 6000
Shared drives: Copies itself to network-shared folders.
Target of infection: Copies itself to KaZaA-shared folder.


When W32.Lovgate.Y@mm runs, it does the following:


Copies itself as the following files:

%Windir%\Systra.exe
%System%\iexplore.exe
%System%\RAVMOND.exe
%System%\WinHelp.exe
%System%\Kernel66.dll


Notes:
%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.
%System% is a variable: The worm locates the System folder and copies itself to that location. By default, this is C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).


Creates the following files:

%System%\ODBC16.dll
%System%\msjdbc11.dll
%System%\MSSIGN30.DLL
%System%\LMMIB20.DLL
%System%\TkBell.exe
%System%\Update_0B.exe
%Windir%\svchost.exe

Note: These files are all the same. They are backdoor components of the worm, each 53,760 bytes in size.


Creates and executes the file %System%\NetMeeting.exe (61,440 bytes). This file is detected as W32.Lovgate.R@mm.

When the file runs, it does the following:

Copies itself as %System%\spollsv.exe.


Adds the value:

"Shell Extension" = "%system%\spollsv.exe"

to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

so the worm runs when you start Windows.


Attempts to create %System%\a in other systems using the Microsoft Windows DCOM RPC Interface Buffer Overrun Vulnerability. This file is an FTP script that is used to get hxdef.exe from the infected system.


May create these files in the %System% folder.
results.txt
win2k.txt
winxp.txt

These files are not viral by themselves, and as such, are not detected.


Adds the values:

"Program in Windows"="%system%\iexplore.exe"
"Protected Storage"="RUNDLL32.exe MSSIGN30.DLL ondll_reg"
"VFW Encoder/Decoder Settings"="RUNDLL32.exe MSSIGN30.DLL ondll_reg"
"WinHelp"="%system%\WinHelp.exe"
"Hardware Profile" = "%system%\hxdef.exe..."
"Program in Windows"="%system%\IEXPLORE.exe"
"Microsoft NetMeeting Associates, Inc."="NetMeeting.exe"

to the registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

so that the worm runs when you start Windows.


Adds the values:

"SystemTra"="%Windir%\SysTra.exe"
"COM++ System" = "svchost.exe..."

to the registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunServices

so that the worm runs as a service when you start Windows 95/98/Me.


Adds the value:

"run"="RAVMOND.exe"

to the registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows\

so that the worm runs when you start Windows NT/2000/XP.



Adds the following line to the [Windows] section of the Win.ini file:

run=ravmond.exe


Creates a network share, "Media," which is mapped to "%Windir%\Media." It copies itself to all the network-shared folders using one or more of the following names:

Thank you.doc.exe
3D Flash Animator.rar.bat
SWF Browser2.93.txt.exe
Download.exe
Panda Crack.zip.exe
WinRAR V3.2.0 Beta 2.exe
Swish2.00.pif
AAdobe Photoshop7.0 creak.pif
You_Life.JPG.pif
CloneCD crack.exe
WinZip v9.0 Beta Build 5480 crack.exe
Real-DRAW PRO v3.10.exe
Star Wars Downloader.exe
HyperSnap-DX v5.20.01.exe
Adobe Photoshop6.0.zip.exe
HyperSnap-DX v4.51.01.exe


Creates two files named AUTORUN.INF and COMMAND.EXE in the root folder of all the drives, except for the CD-ROM drives.


Creates an archive file named <filename>.<ext> in the root folder of all the drives, unless the drive letter is A or B.

<filename> will be one of the following:

WORK
setup
Important
bak
letter
pass

and <ext> is one of the following:

RAR
ZIP

This zip file contains a copy of the worm with the file name <filename>.<ext>.

<filename> is one of the following:

WORK
setup
Important
book
email
PassWord

and <ext> is one of the following:

.exe
.com
.pif
.scr


Creates the service, "Windows Management Protocol v.0 (experimental)," which is mapped to "Rundll32.exe msjdbc11.dll ondll_server".


Creates the service "_reg" that is mapped to "Rundll32.exe msjdbc11.dll ondll_server".


Terminates all the processes that contain any of the following strings:

KV
KAV
Duba
NAV
kill
RavMon.exe
Rfw.exe
Gate
McAfee
Symantec
SkyNet
rising


Scans all the drives. If the drive type is removable, mapped, or if the drive type is fixed with a drive letter greater than E, it does the following on all the drives found:

Attempts to rename the extension on all .exe files to .zmx.
Sets the attributes to Hidden and System on these files.
Copies itself as the original file name.


Injects a process-watching procedure as a thread into either Explorer.exe or Taskmgr.exe. This thread will attempt to launch %System32%\Iexplore.exe if it detects that the worm process is stopped.


Listens on port 6000. The backdoor procedures steal the information of a compromised system and stores it in the file, C:\Netlog.txt. Then, the worm emails the stolen information to the hacker.


Finds the location of the KaZaA-shared folder in the system registry. Then, it creates a copy of itself in the KaZaA-shared folder as one of the following (with a .bat, .exe, .pif, or .scr file extension):

wrar320sc
REALONE
BlackIcePCPSetup_creak
Passware5.3

If the worm successfully logs on to the remote computer, it will attempt to copy itself as:

\\<remote computer name>\admin$\system32\NetManager.exe

and to start the file as the service, "Windows Management NetWork Service Extensions", which is mapped to "NetManager.exe -exe_start".

Removal using the W32.HLLW.Lovgate [url=\"http://securityresponse.symantec.com/avcenter/venc/data/w32.hllw.lovgate.removal.tool.html\"]Removal Tool[/url]
Symantec Security Response has created a removal tool to clean the infections of W32.Lovgate.Y@mm.This is the easiest way to remove this threat.


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.
Reverse the changes made to the registry.
Reverse the changes made to the Win.ini file (Windows 95/98/Me only).
Run a full system scan and delete all the files detected as W32.Lovgate.Y@mm.
Rename the .zmx files to the .exe files.

To reverse the changes made to the registry

Before continuing, Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. For instructions, read the document, "How to make a backup of the Windows registry."

Click Start > Run.
Type regedit

Then click OK.


Navigate to the key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run


In the right pane, delete the values:

"Winhelp" = "%system%\TkBellExe.exe..."
"Hardware Profile" = "%system%\hxdef.exe..."
"Program in Windows"="%system%\IEXPLORE.exe"
"Microsoft NetMeeting Associates, Inc." = "NetMeeting.exe"
"Protected Storage"="RUNDLL32.exe MSSIGN30.DLL ondll_reg..."
"VFW Encoder/Decoder Settings"="RUNDLL32.exe MSSIGN30.DLL ondll_reg"
"WinHelp"="%system%\WinHelp.exe"
"Shell Extension" = "%system%\spollsv.exe"


Do one of the following:
If you are using Windows NT/2000/XP, skip to step h.
If you are using Windows 95/98/Me, proceed with step f.


Navigate to the key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunServices


In the right pane, delete the values:

"SystemTra"="%Windir%\SysTra.exe"
"COM++ System" = "svchost.exe..."

When you have deleted these values, proceed with step j.


Navigate to the key:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows


In the right pane, delete the value:

"run"="RAVMOND.exe"


Navigate to the key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services


In the left hand pane, delete the subkeys:

_reg

Windows Management Protocol v.0(experimental


Exit the Registry Editor.


Do one of the following:
If you are using Windows NT/2000/XP, skip to section 6, "To scan for and delete the infected files."
If you are using Windows 95/98/Me, proceed with section 5.



5. To reverse the changes made to the 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:

edit c:\windows\win.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 [windows] section of the file, look for a line similar to:

run=ravmond.exe


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


Click File > Save.
Click File > Exit.

To scan for and delete the infected files
Start your Symantec antivirus program and make sure that it is configured to scan all the files.
For Norton AntiVirus consumer products: Read the document, "How to configure Norton AntiVirus to scan all files."
For Symantec AntiVirus Enterprise products: Read the document, "How to verify that a Symantec Corporate antivirus product is set to scan all files."
Run a full system scan.
If any files are detected as infected with W32.Lovgate.W@mm, click Delete.
Restart the computer in Normal mode. For instructions, read the section on returning to Normal mode in the document, "How to start the computer in Safe Mode."


7. To rename the .zmx files to the .exe files
As W32.HLLW.Lovgate.Y@mm renames many .exe files, rename them to the correct extension for them to work.

Follow the instructions for your operating system:
