CWS Variants

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 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 list of all known CWS domains can be found here :

drxcount.biz / real-yellow-page.com

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 :

Click Me

Usually, the following instructions are given now :

 

CWS.Systeminit variant - (hijacks to your-search.info, in some cases to another CWS domain)

Note* : CWShredder takes care of this successfully so far

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 :

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)

Edit by DVK01: main problem with this one is that the O4 entry doesn't show in the HJT log.
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.

More info HERE

Responsible entries in a HijackThis log :

R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = mkMSITStore:C:\WINDOWS\start.chm::/start.html
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = mkMSITStore:C:\WINDOWS\start.chm::/start.html

A workaround for this exploit is provided HERE

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
HERE

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 :

Notepad will open at the end with a message and the bad file listing at the end. Ask the user to post the contents of that notepad box.

 

runwin32.exe, wininet32.exe (write-up by Pieter Arntz)

Hijacks to a CWS domain (searchmeup, easy-search.biz etc)

Responsible entries in a HijackThis log :

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = hxxp://www.searchmeup.com/search.php?aid=1057

O4 - HKCU\..\Run: [wininet32] C:\WINDOWS.000\wininet32.exe
O4 - HKCU\..\Run: [runwin32] C:\WINDOWS.000\runwin32.exe

The tricky part here is, that it overides your proxy settings! :

Note* : The shredder should be updated for this soon

OsbornTech Popup Blocker

This is a fake entry created by CWS mainly to try and trick HijackThis analysers to not have fix this entry, so re-infection could be easier or clean-up wouldn't be proper

Responsible entry in a HijackThis log :

O2 - BHO: OsbornTech Popup Blocker - {FF1BF4C7-4E08-4A28-A43F-9D60A9F7A880} - C:\WINDOWS\System32\mshelper.dll

(Notice the mshelper.dll to identify it)

Note* : The shredder is updated and should take care of this entry.

Log example :

nkvd.us

A classic one that is spreading around now again with some more tricky coding added to it, more specificly the mtwirl.dll / mtwirl32.dll file (use killbox to clean that one up).

Responsible entries in a HijackThis log :

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = hxxp://nkvd.us/

O13 - Home Prefix: hxxp://www.nkvd.us/
O13 - Mosaic Prefix: hxxp://www.nkvd.us/

O19 - User stylesheet: c:\windows\my.css

Fix these entries with HijackThis, restart PC in Safe Mode and manually remove mtwirl.dll / mtwirl32.dll (in system/system32 folder)

Use this registry fix after clean-up :

msole.dll

Hijacks to a CWSdomain (R0 and R1 entries in a HijackThis log), using a 02 BHO

Responsible entries in a HijackThis log :

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = www.payfortraffic.net**/search.htm
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = www.payfortraffic.net**/mainsearch.htm

searchpage.html

Another variant that has been spotted which looks like a combo of nkvd.us and master-search.

Responsible entries in a HijackThis log :

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = c:\searchpage.html#1504
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = c:\searchpage.html#1504

O13 - WWW Prefix: c:\searchpage.html?page=
O13 - Home Prefix: c:\searchpage.html?page=
O13 - Mosaic Prefix: c:\searchpage.html?page=

Those are the only visible entries in that log.

Still awaiting how shredder deals with this and for more info about the possible culprit of this hijack (dll).

Update* :

The fake OsbornTech has been spotted with this one as well :

O2 - BHO: OsbornTech Popup Blocker - {FF1BF4C7-4E08-4A28-A43F-9D60A9F7A880} - C:\WINDOWS\System32\mshelper.dll

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.

Log Example :

HERE

 

IEengine.exe (hijacks to a CWS domain)

Drops the exe in the Internet Explorer folder in Program Files to make it look as legit as possible

Responsible entries in a Hijackthis log :

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = hxxp://your-searcher.com/index.htm
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = hxxp://your-searcher.com/index.htm

etc.

O4 - HKCU\..\Run: [IEengine] C:\Program Files\Internet Explorer\IEengine.exe

*Shredder should be updated soon for this

For those who are interested, a disassembly report after unpacking the exe(done by Mo) can be downloaded HERE

Log example :

HERE

Also spotted with (not always present though):

O4 - Global Startup: winlogin.exe

CWShredder normally finds and deletes those 2 in XP/W2K but it needs manually fixing in ME/9X

 

mrhop.dll

Although it looks very similar to the variant described in post 4, it works differently.

O2 - BHO: (no name) - {33B13F77-E06C-4C6F-B347-EBF7CE2BC08F} - C:\WINDOWS\mrhop.dll

Download and install APM from: http://www.diamondcs.com.au/index.php?page=apm
In the upper window select explorer.exe
In the lower window find and rightclick mrhop.dll
Select Unload DLL and click OK on the prompts that follow.

Close all windows except HijackThis and fix the lines above.
Reboot and scan with AdAware.

 

system32.dll (jksearch.biz , greatsearch.biz)

*NOTE :


As of HijackThis version 1.98.1 a line similar to this will show:
O21 - SSODL: System - {1F0B125B-7C1F-4B45-BAE9-20FEEF841480} - C:\WINDOWS\system32\system32.dll
Fixing that will have the same effect as the first line in the clear.reg fix.
