View Full Version : CWS Variants
Unzy
April 20th, 2004, 06:56 AM
Lately a new strain of cws variants are following eachother very rapidly.
They are becoming harder and harder to clean because they are using all sorts of tricks to prevent scanning tools from detection or proper removal (like re-infection).
It's getting more difficult now for Merijn to update CWShredder (http://www.spywareinfo.com/~merijn/files/CWShredder.exe) both because of the more complex coding and the amount of new types/variants that appear on a very regulary basis.
Bare in mind that experts are working around the clock looking for successfull removal tips and prevention fixes.
This means however, that as long as the shredder is not updated, victims will be advised to clean their infection manually. Although experts and more savy computer people are used working in the registry, and all sorts of tools which involves editing in windows it will be more and more difficult for the normal computer user to clean up once he/she is infected. Advise given by expert people may look rather complex, when having any doubts whatsoever, don't hesitate to ask for more advise.
Expertised people in this area (on this board) who are more closely involved in analysing and know the latest details are :
Pieter Arntz (aka Metallica on other numerous boards)
dvk01
shadowwar
Feel free to contact one of the mod's if any questions. They are all very knowledgable and will at least be able to point you in the correct direction :
dave38, puff-m-d, wizard, Technodrome, JacK, Dan Perez, MickeyTheMan, Detox, Unzy, snowbound, snapdragin, rodsoto, bigc73542
Below follows a summation of those new strains of more complex CWS variants, beginning with the drxcount one,which seems to be the first one to introduce a whole new set of invisible CWS hijacks and tricky coding. I will try to give the most common instructions summed by experts. Some of them work very well, other are a bit complex. Some work for user X, while user Y complains of a re-infection, after following the exact same instrucions.
Note :
After cleaning a CWS infection always check your 'Favorites' folder for added porn links***

A very great place to start, where we gathered all info together with infected users is a topic started by Pieter Arntz (Metallica). It shows investigation of expert people nicely evolving from sleepless nights to succesfull removal instructions! If you are interested in reading the developments you can check it here :

Usually, the following instructions are given now :

We are working on a fix for this one and drawing near to a solution. This is by far the most sophisticated CWS variant seen to date, and it will take some time before CWShredder will be able to remove it automatically.
So far, the following manual fix should work:
Download PrcView here: http://www.spywareinfo.com/~merijn/files/pv.zip, unzip it to the desktop.
Be sure to have at least 1 Internet Explorer window open, then double click on the runme.bat.
Notepad will open with a log in it. Look for a line with this file, size and beginning to it.
The filename will always be different:
winajbm.dll 61c00000 61440 c:\windows\system32\winajbm.dll
This part indicates the bad file:
61c00000 61440
It will always start with that header.
Write down the filename behind it.
Now download KillBox:
http://download.broadbandmedic.com/VbStuff/KillBox.zip
Unzip and run it.
Don't click any of the buttons though, instead please click on the Action menu and choose "Delete on Reboot".
On the next screen, click on the File menu and choose "Add File". The file you copied earlier should now show up in the window. If that's successful, choose the Action menu and select "Process and Reboot". You'll be prompted to reboot, do so.
After rebooting, make sure the file is gone

This is a very complex hijack to solve for now, as only manual instructions are given. Please only follow instructions when you are guided by an Advanced or Expert member!
Responsible entries in a HijackThis log :
R0 and R1 entries pointing to the following similar looking location : res://C:\WINDOWS\System32\kfiokk.dll/sp.html
O2 - BHO: (no name) - {54DDBEA0-AAE2-43A1-9076-3F064D0DEA55} - C:\WINDOWS\System32\kfiokk.dll*
* the dll is randomly named for each victim, and is showed as a 02 - BHO in a HijackThis log.
Although the entries in a HijackThis log are pretty obvious, the tricky part of this variant is a cleverly disguised re-infection method, after a certain amount of time when the victim connects again to the internet.
The methods so far all failed to give a 100% clean result, even with an updated shredder for this particular variant, so I'm not gonna bother to list them here, as experts are now in the middle of looking for answers, as we speak. As soon as we have a successfull removal method, this topic will be updated.
For those interested I can inform what we gathered so far :
It all comes down to these two files :
{QUOTE->
1. The randomly named BHO file (a .dll) in the system (win9x/ME) or system32 (win2k/XP) folder with the corresponding ClassID's (in some logs there were up to 11 morphed ones!)
2. The AppInit_DLLs entry, a registry key which points to a hidden dll located in the system/system32 folder, responsible for the re-infection.
<-QUOTE}
The key is :
Trying to make this superhidden dll visible so it's removable! Lately, it seems best to start with the removal of this dll, before following other instructions!
*UPDATE!
Shadowwar has pulled dllfix, too many bugs and variants within the hijack itself are making it impossible to work properly.
It's best to post your problem at the corresponding forums, and wait untill you get a responce from an expert, for further guidance.
Download and run AdAware : http://www.lavasoft.de/software/adaware/ (make sure you have latest updates) and run it, after doing so post your HijackThis log.
Old fix : (keeping this here, just in case)
As we are drawing near a successfull removal method, this is the canned fix of procedures to follow :
(Note that at this time only manual instructions are given and they can be somewhat complex)
© freeatlast :
*for win2k / XP (win98 is at bottom)
{QUOTE->
1.)
***Identifying the file***
http://freeatlast.100free.com/index.html
Download find-all.exe (win2k/xp only!)
run findall.cmd and post log
At this point, based on "output.txt"
and "windows.txt" we should have the file name:
***Removal***
Based on the "System info" header in
"Find-All", 'Fat32/NTFS', can pick the best course of action.
--2K/XP/Pro/home/Fat32/Ntfs ALL can use Recovery console.
I will not list the steps, some users would need guidance
and for some it may not be an option .
--2K/XP/Pro/home/Fat32< only (minority, most likely)
Can go to bootdisk.com make Win95/98 startup disk, and
nuke the file by accessing the partition with
basic known good ol' dos commands!
=============================================
***If NOT using Dos/RC option***:
The only known working way, currently is by
renaming the 'Windows' key-- Applies to both fat/ntfs
supported sys.
Tools:
1.) Registrar Lite (http://www.resplendence.com/reglite)
2.) RegAlyzer (http://www.safer-networking.org/index.php?page=regalyzer) By PepiMK, (also known from SpyBot S&D!)
Same procedure in both tools to
rename the key, erase data, rename back, followed
by RESTARTING the computer! :
{QUOTE->
-Run reglite : type--
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\\AppInit_DLLs
into the address bar, or expand the same key.
-Rename the Folder Windows
to NotWindows highlighted as a purple folder
in the left hand pane of reglite.
-Click "AppInit_DLLs" again and clear the data value:
C:\WINDOWS\System32\xxxxxxx.dll (random named dll) <- delete this line ,
'Apply' and 'ok' to set.
-Rename the NotWindows folder back to its
original name Windows
-Restart computer
Check in the system32 folder if the culprit dll is visible
<-QUOTE}
***Delete File***
Only needed for:
--2K/XP/NTFS< !
--Move file+Modify it's permissions:
1.) Go to your root drive: C:\ and create
new folder,
Name it: "junk"
Download, unzip to folder and run WinFile.zip (http://www10.brinkster.com/expl0iter/freeatlast/WINFILE.zip) (note : for win2k/xp!)
Expand and navigate to System32 folder.
You need to navigate by Double clicking to expand.
When in System32 click top menu: File>Select files
Copy and paste to the box:
xxxxx.dll hit select-
Find and hilite that file.
Lastly, try this: Menu -File>move...
In From: Copy/paste:
C:\WINDOWS\System32\xxxxxx.dll
To: Copy and paste:
C:\junk\xxxxxx.dll
And hit ok.
Close Winfile and check in C:\junk for that file.
2.)
RightClick on the
junk\"xxxxxxx.dll"/Properties/Security/permissions\
advanced,
and take ownership giving yourself-> 'Full control'.
(Preferably to Administrators 'group')
3.)

{QUOTE->
-Right click the "junk folder" folder itself.

-go to the security tab and click the advanced button.
-check the box-
to reset permissions on all child objects.
Hit apply.
ok your way out.
File can now go bye bye!
<-QUOTE}
4.)
Delete file+junk folder.
-------------------------------------------------------------------------
--WinXP home edition/NTFS (only!):
Must Follow last Steps# 2-4 in Safe Mode
in order to access security tab.
(Alternatively run cacls.exe, if familiar)
--2K/XP/All-versions/Fat32< only,
Can simply find and delete the file after
restart! (skip all 'winfile' &onward steps!)
=======================================
***ALL platforms/sys that
renamed the 'Windows' key:***
--Because we renamed it, Windows REMOVED defaults
security settings on this key and
allowed the 'everyone' group read access!
(Just as if new key was created)
(regedt32 started alerting me that the "new" key
settings are incomatible with windows! )
***Repair***:
--*WinXP/Pro/Home:
-> regedit.exe-> RightClick 'Windows'->
->Security/permissions/Advanced
*Win2K ->regedt32-> hilite 'Windows' key->
->top menu->Security
->permissions->Advanced tab
--------------------------------------------------------------
UNcheck: "inherit permissions" box,-> Select
COPY on next prompt!
(That will restore last saved settings in database)
-Hilite "Everyone" (group/only!)->Select-> REMOVE!
-Hit 'Apply and 'ok' on all check boxes.

*WIN98
Tools :
Win98Fix (http://www10.brinkster.com/expl0iter/freeatlast/pvtool.htm)
StartDreck (http://members.blackbox.net/hp_links/21/nikolaus.rameis/download/startdreck.htm)
{QUOTE->
**Identify file:**
Download: "StartDreck", unzip!
DoubleClick: 'StartDreck.exe'
Hit: config
hit: Unmark all
Check these boxes only:
Registry->run keys
System/drivers> Running processes
hit >ok.
Check specificly for this entry in the log :
{QUOTE->
»Local Machine
»RunServicesOnce
**ozkc=rundll32 C:\WINDOWS\SYSTEM\XXXXX.DLL,StreamingDeviceSetup
<-QUOTE}
After identifying the dll, proceed with :
-Download: "Win98Fix.zip", Unzip!
-DoubleClick on: 'RunFix.reg' file, hit 'yes'
on the prompt!
-Restart computer!
-File should be visible!
-Do 'find files' for dll listed on log, delete.
*Note: Be sure to Save the StartDreck log before, so
you you'd be able to find the file later!
If lost (Since nothing else will find it when not hooked)
Simply run the included: "who.bat", file
will be found & listed
in "Badfile.txt".
<-QUOTE}
It should be located in C:\WINDOWS\SYSTEM\XXXXX.dll
Note* Please follow instructions carefully, doublecheck before you delete and make sure you have a backup of your registry : HERE's How (http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/199762382617)

The jushed32.exe does show in running processes and once you have stopped it running and deleted it then the O4 appears so it can also be fixed

start.chm / MSITStore (MasterSearch)
A new type of CWS variant that uses an exploit to reset a user's homepage.

A workaround for this exploit is provided HERE (http://netsecurity.about.com/cs/generalsecurity/a/aa021504.htm)
There should be an official microsoft patch soon, please keep an eye for updated patches at windowsupdate.com
NOTE* : There is offered a removal tool (remove.exe) on their site which seems legit and does work, however it is believed it creates a GUID (Global Unique IDentifier) which can always 'distinguish' a user, meaning : they can track you down and follow your actions on the net, kinda like WMP.
NOTE 2*: CWShredder removes start.chm and start.html as of version 1.56.3 It does not always cure the Hijack (yet).
Log example :

HERE (http://www.wilderssecurity.com/showthread.php?p=161042)
EDIT: It seems that there is normally a file in the temp directory that has something to do with this one as well so also clear out the temp folder
on W2K & XP it will be C:\Documents and Settings\user name \Local Settings\Temp
on 9x/ME systems c:\windows\temp
on XP/W2k select and delete eveything in the folder
on 9x systems select everything except temporary internet files folder and cookies folder
You will need to do the cleaning for every account holder on the computer
Update** :
Shadowwar has come up with a fix for this particular hijack :
{QUOTE->
Please download this to fix the start.chm hijack.
http://tools.zerosrealm.com/startchmfix.exe
Download it. Run it and extract the folder to the desktop preferably.
Open the folder after extracted.
Double click the fix.bat
Please make sure all Internet Explorers are closed.
Only run it once or you will lose the backups although they shouldn't be needed.

CHP.DLL
Symptoms :
-Explorer has caused an error in CHP.DLL, which causes Internet Explorer to crash. (Thnx to bad coding probably :) )
-Messes with Windows media Player (WMP) (not working properly anymore)
Stripping the UPX packed file revealed the following link : lookingfor.cc/search.php, which is a cws domain
Removal :
Unregister the dll
Visible entries in a HijackThis log :
None
Update* : It's not a random named dll, other people were experiencing the error message as well refering to this dll. Most likely a result of bad coding from one of the variants.

The second executable is run as a service named __NS_SERVICE_3 (we have seen __NS_SERVICE_2 a few times as well). In the services window it is listed as Network Security Service. That service installs the BHO dll. When you launch IE for the first time the BHO adds the RO/R1 entries.
log example: HERE (http://www.wilderssecurity.com/showthread.php?t=36583)
NOTE: the files are not necessarily in the System32 folder. We have seen them in the Windows directory as well.
Removal:
Make sure your settings allow you to view "Hidden files". Open up any explorer windows and click on "Tools" => "Folder Options" => "View" and be sure to check off "Show Hidden Files and Folders".
Press Ctrl+Alt+Delete once => Click Task Manager => Click the Processes tab => Double-click the Image Name column header to alphabetically sort the processes => Scroll through the list and look for "" & "". If you find the files, click on them, and then click End Process => Exit the Task Manager.
Next, go to Start->Run and type "Services.msc" (without quotes) then hit OK.
Scroll down and find the service called "Network Security Service".
When you find it, double-click on it. In the next window that opens, click the Stop button, then change the Startup Type to Disabled. Now hit Apply and then OK and close any open windows.
Run HijackThis, click on "Scan" and then place a check mark in the following boxes, And click on "Fix Checked":
<insert R* entries>
<insert BHO entry>
<O4 entries for exe's>
Reboot into Safe Mode - How do I boot into "Safe" mode? (http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406?OpenDocument&src=sec_doc_nam), and delete the following files:
<insert R* entry dll>
<insert BHO dll>
<insert listed exes>
Reboot in Normal Mode.
Download the file attached to this post and rename it to cwsuninst.reg
Doubleclick it and confirm you want to merge it with the registry.
Run HijackThis again and post a new log.
Extra notes
If given full internet access this variant will delete:
- your hosts file (good replacements can be found here (http://www.mvps.org/winhelp2002/hosts.htm) or here (http://webpages.charter.net/hpguru/hosts/hosts.html))
- Spybot S&D's BHO (download SDHelper.dll (http://www.spywareinfo.com/~merijn/winfiles.html), put it in the Spybot folder (default is: C:\Program Files\Spybot - Search & Destroy\) and click Start > Run > regsvr32 "C:\Program Files\Spybot - Search & Destroy\SDHelper.dll" > OK
- control.exe: follow instructions here: http://www.spywareinfo.com/~merijn/winfiles.html#control
Another extra note:
In the latest variant it’s possible that the service changed its name.
Currently known service-names are:
- Workstation Netlogon Service
- Remote Procedure Call (RPC) Helper
As you may notice they are mimicking legit (and very much needed) services, so be carefull what you stop.

Still doing some tests for removal, but sofar it looks like fixing the items in the log and removing the files in the log plus
%Windir%\bad3074.exe takes care of the hijack.
Use AdAware's smart system scan to remove some unpleasant additions to your favorites and some registry keys.
A slightly newer variant is being spread. Extra line(s)
O4 - HKLM\..\Run: [pnpsvc_lock] C:\WINDOWS\System32\64302.exe (filename is a random number)
O4 - Global Startup: winlogin.exe (Also seen in combination with other variants)
In this newer version it is not always possible to remove the file starting from the AppInit_DLLs location.
Renaming the file will allow you to delete it after a reboot.

Answer 'Yes' and wait for a message to appear similar to "Merged Successfully"
Third:
Before we begin, please be sure that* HiJackThis is in its own folder. This will allow us to use backups to restore entries if necessary. Please do not put HiJackThis in a* temporary folder, or on the Desktop. I suggest using 'c:\program files\hijackthis\' or C:\HiJackThis\, but any name you choose is fine.
Reboot in Safe Mode* and run HiJackThis.* <-- IMPORTANT
Check the following items in HijackThis.
Close all windows except HijackThis and click Fix checked.
While still in Safe Mode*, delete the following:* (you may need to show hidden files**)

Also, uncheck the boxes for hiding known file extensions and hiding protected operating system files. We want to see it all. When we finish here, it would be a good idea to rehide the protected operating system files but leave the rest to be shown.
Reboot in normal mode.
HiJackThis version 198.2 is now available.
If you do not already have it installed, download it from here:

Run HiJackThis again and post a new log in this thread.
Addendum:
There are also some zero (0) byte files that this exploits leaves behind. They are installed to prevent the competiton from re-installing itself. This one removes a lot of other spyware.
The ones that have been seen so far are:
D2KPAX.DLL
BRIDGE.DLL
JAC.DLL
MSXSLAB.DLL
SYSTEM32.DLL
WINLOGIN.EXE
Use DLLCompare by O^E to find them. If they refuse to delete try this batch file:

ren D2KPAX.DLL D2KPAX.bad
del D2KPAX.bad

Several variants using a .hta file in the All Users Startup folder.
I have seen:
O4 - Global Startup: Microsoft.hta
O4 - Global Startup: M-soft Office .hta
O4 - Global Startup: Microsoft Office.hta
O4 - Global Startup: MS Office.hta
All work slightly different, but the endresult is you get hijacked to a CWS domain.

Variant known as PremiumSearch aka EasySearch
An installer called l04d3r.exe is dropped and executed using a variant of the "Auto SP2 RC Exploit" covered in http://www.microsoft.com/technet/security/bulletin/MS05-001.mspx
Two files are dropped in :\Documents and Settings\[current user]\Local settings\Temp
The dll is random. The other file is not always present and called winmain.exe
After stripping the attributes (metallica.bat does that), running Cleanup gets rid of all the files.
Proposed fix:
Step 1
[b]*IMPORTANT* Be sure you know how to VIEW HIDDEN FILES (http://www.xtra.co.nz/help/0,,4155-1916458,00.html)
Download and unzip http://metallica.geekstogo.com/MADEbyOSC.zip
Run the file by doubleclicking metallica.bat
and post the log.
Do not reboot untill someone has looked at your log and given you the next step.
If you have to reboot repeat this part when you are back online.
