Fake Flash Player and Trojan DNSChanger.gen

Steve has found a very interesting sample in the wild that looks like a fake flash player that installs the DNSChanger trojan in the victim’s computer. The malicious file is named FlashPlayer.v..exe:

A new window appeared on the screen and asked me where to install a program named homeview:

The program creates the following files:

C:\resycled\boot.com
C:\WINDOWS\system32\drivers\msqpdxpqxtoiqh.sys
C:\WINDOWS\system32\msqpdxosvnnrse.dll

We can see that it has dropped a rootkit driver in C:\WINDOWS\system32\drivers\, called msqpdxpqxtoiqh.sys, after the hidden execution of a file called jah30006.exe. Another interesting file is C:\autorun.inf that is used by the trojan to spread itself on removable devices such as USB Drives.

With RkU we can see the malware hooks some functions in ring0:

 

ring0 hooks

 

It also detected stealth code:

 

Stealth code detected

 

We can see the registry key of the rootkit driver in regedit:

 

Registry keys of the rootkit driver

 

But we cannot delete the key because of the hooks that protect the registry key from being deleted by the user:

 

Error deleting the rootkit driver registry key

 

Following files are hidden from explorer search because of the hooks that obfuscate the presence of the files:

C:\WINDOWS\system32\msqpdxosvnnrse.dll

During the analysis, the malware was always establishing connections with:

O17 – HKLM\System\CCS\Services\Tcpip\Parameters: NameServer = 85.255.116.74;85.255.112.167

We can see that the malware change the Tcpip Parameters and everytime you visit a site you will send traffic to these IPs:

85.255.116.74
85.255.112.167

How to remove Trojan DNSChanger.gen ?

 

1] Boot in Safe Mode (F8)

 

2] Find and delete all the files related to the trojan, in my case:

1
2
3
4
5
6
7
8
%User%\LOCALS~1\Temp\jah30006.exe
C:\autorun.inf
C:\Program Files\homeview
C:\Program Files\homeview\Uninstall.exe
%User%\Start Menu\Programs\homeview\Uninstall.lnk
C:\resycled\boot.com
C:\WINDOWS\system32\drivers\msqpdxpqxtoiqh.sys
C:\WINDOWS\system32\msqpdxosvnnrse.dll

3] Remove the hijacked Tcpip Parameters in the registry:

1
2
HKLM\System\CS1\Services\Tcpip\Parameters: NameServer = 85.255.116.74;85.255.112.167
HKLM\System\CCS\Services\Tcpip\Parameters: NameServer = 85.255.116.74;85.255.112.167

4] Remove the registry keys created by the malware:

1
2
3
4
5
6
7
8
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msqpdxserv.sys
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\msqpdxserv.sys
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_MSQPDXSERV.SYS
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_MSQPDXSERV.SYS
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_MSQPDXSERV.SYS
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\msqpdxserv.sys
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\msqpdxvx
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\msqpdxserv.sys

If the registry keys related to the rootkit driver cannot be deleted with regedit.exe use regedt32.exe (suggested by Simon).

  1. Thanks for posting this, been researching this virus to try and completely remove it from my computer but it always seems like I’m missing a few files or registry keys. Wasn’t aware of the added files to the drivers folder or the changes to HKLM\System in the registry. From what I’ve seen, the filenames for the files it creates are partially randomly generated, always starting with msqpdx with the exception of msqpdxserv.sys.

  2. Yeah, looks like this variant to me.

    http://www.f-secure.com/v-descs/trojan_w32_dnschanger_arnf.shtml

  3. Any idea how I can get rid of it? Short of reformatting my primary hard disk? How can I unhook the hooks?

  4. You can use Rootkit Unhooker (you will find it here: http://novirusthanks.org/blog/?p=16) to unhook the code hooks, then you can delete the files and remove the Tcpip Parameters that were added by the malware.

    -Files to delete:
    C:\DOCUME~1\user\LOCALS~1\Temp\jah30006.exe
    C:\autorun.inf
    C:\Program Files\homeview
    C:\Program Files\homeview\Uninstall.exe
    C:\Documents and Settings\user\Start Menu\Programs\homeview\Uninstall.lnk
    C:\resycled\boot.com
    C:\WINDOWS\system32\drivers\msqpdxpqxtoiqh.sys
    C:\WINDOWS\system32\msqpdxosvnnrse.dll

    -Tcpip Parameters to remove:
    HKLM\System\CS1\Services\Tcpip\Parameters: NameServer = 85.255.116.74;85.255.112.167
    HKLM\System\CCS\Services\Tcpip\Parameters: NameServer = 85.255.116.74;85.255.112.167

  5. I had this infection too (my first infection in 10+years of being online). Is it necessary to delete msqpdxserv.sys? I used Malwarebyte’s Anti-malware to delete all the other files, but the registry item can’t be deleted. Should I be searching out a way to delete it? Thanks.

  6. Thanks Robert, your advice worked like a charm. However, I found some differences between this report and my case.

    I have an entry in my registry called LEGACY_MSQPDXSERV.SYS under HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_MSQPDXSERV.SYS that I still can’t delete.

    Another one is msqpdxserv.sys under HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\msqpdxserv.sys

    I can’t find the hooks for these using RkU, maybe its just my inexperience with it. However, I think its just dead entries in the registry as my DNS is no longer changing, and a boot-time scan using Avast yields a clean result.

  7. Update:

    found also HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msqpdxserv.sys

    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\msqpdxserv.sys

    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_MSQPDXSERV.SYS

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_MSQPDXSERV.SYS

  8. Good find hans, if you still have problems to delete the registry keys you can boot in Safe Mode (press F8 when PC start) and then delete the remained keys you have found:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msqpdxserv.sys
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\msqpdxserv.sys
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_MSQPDXSERV.SYS
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_MSQPDXSERV.SYS
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_MSQPDXSERV.SYS
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\msqpdxserv.sys

    If you cannot delete these registry keys, it means the rootkit driver is still loaded, so maybe the .sys file was not deleted, try in Safe Mode and re-check if are present the rootkit driver and the other files and delete them if present

    -Robert

  9. Rebooted in safe mode, none of the files are present. Ran RkU and unhooked everything, still can’t delete the entries. Any ideas?

    -Hans

  10. Have you tried to delete the registry keys in safe mode from regedit ?

  11. Yeah, same here. I’m in safemode using regedit, but it says I cannot delete those entries that Hans mentioned.

  12. Solved. Run regedt32 (note spelling) instead of regedit in safe mode. Then right-click on the offending registry entry, select Permissions. The give Full Control to Everyone. Now you can delete the entry.

  13. Hey, thanks very much to all you guys, I couldn’t get rid of this from the registry before I read your posts on setting permissions..

    Thanks again

    John

  14. I’ve try everything you post here … but I still cannot delete Keys in Registry … Everything I change in Permissions, I’ve got an error.

  15. Access denied when I tryed to set permissions … :(

  16. Solved for me too!!

    Very important is to enter to regedit 32
    I made a search through all the registry for strings with the initial MSQPD and found some enteries that weren’t mentioned here.
    It is important to delete them all.
    Thank you all!!

  17. OK … I did it (a little bit different, but I’ve got control over register). But now I have a new problem. I’ve also find a DNS entry, which are set by this Trojan. So … I clean everything (in Safe mode), but everytime I restart my computer, registry entry are there again … WTF????

    I

  18. I mean … entry for MSQPDXSERV without DNS entry

  19. Hey Sammy, can you post here the HiJackThis Log ? Maybe there is something that was not deleted and that is auto-started when windows start

  20. Hey Sammy,
    what different thing you`ve done for having acess to the register. just acess denied here for me…

  21. do a rearch for combofix.exe and run it

  22. Samm find a program combofix.exe ……………..I had same redirect virus ran combofix took about 10 mins………… no problem now.

  23. hmm… interesting, I managed to delete everything (with and without the help of anti-malware software) but for some reasons I still have 3 registry entries to which I can not change permissions (and logically can not delete) I used safemode and regedt32… pffff
    running out of ideas… anyone?
    It is as those don’t even exist anymore, they are not hooked… wtf!?

  24. Hi everyone

    I was wondering how do you know if your still connected to the IP address 85.255.116.74

    my friend helped me fixed my computer when it was infected with this, I’m not quite sure if he completely fixed everything though so I’m a bit worried

    hope someone can help

  25. @dadah try to check with Rootkit Unhooker if are still present the SSDT / Code Hooks in your system, if are not present, the malware mainly should be “out”, about registry keys if you set permissions right should there not be problems to delete them, try again in safe mode using the regedt32 “trick” : )

    @Andy if is possible for you please post here a log of HijackThis Log so we can see better if the trojan is still alive : )

    -Robert

  26. I’ve got the same problems reported here, but I can’t get the unhooker to work right. I see the code hooks tab and pick unhook all, but right after I run regedt32 and still don’t see the registry entries even though rootkit has reported them like this: HKLM\SECURITY\Policy\Secrets\SAC* 5/21/2008 10:11 PM 0 bytes Key name contains embedded nulls (*)

    E: 0 bytes Error mounting volume

    am I missing something here

  27. @Robert – I think i did this right hopefully, hopefully i don’t need to fix anything because i’m not very great with computers. My friend fixed my computer and i ran some anti-spyware and anti-virus to clean the things he missed so im not sure if theres anything lurking around still

    Thats all i got

  28. @jim try to do this:

    1) boot in safe mode (press f8 when windows start)
    2) give permissions with regedt32
    3) localize the keys:
    HKLM\SOFTWARE\Classes\msqpdxvx
    HKLM\SYSTEM\ControlSet001\Services\msqpdxserv.sys
    HKLM\SYSTEM\ControlSet003\Services\msqpdxserv.sys
    HKLM\SYSTEM\CurrentControlSet\Services\msqpdxserv.sys

    NOTE:
    check also the possible presence of other registry keys as hans found other keys:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msqpdxserv.sys
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\msqpdxserv.sys
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_MSQPDXSERV.SYS
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_MSQPDXSERV.SYS
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_MSQPDXSERV.SYS
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\msqpdxserv.sys

    Then delete the keys and look if are present these files in the harddisk:

    C:\DOCUME~1\user\LOCALS~1\Temp\jah30006.exe
    C:\autorun.inf
    C:\Program Files\homeview
    C:\Program Files\homeview\Uninstall.exe
    C:\Documents and Settings\user\Start Menu\Programs\homeview\Uninstall.lnk
    C:\resycled\boot.com
    C:\WINDOWS\system32\drivers\msqpdxpqxtoiqh.sys
    C:\WINDOWS\system32\msqpdxosvnnrse.dll

    If these files are present just delete them, now restart your PC and check (with the anti rootkit or manually with regedit) if the registry keys are present.

    @Andy from the HiJackThis Log seem that your computer is clean, anyway try to scan your PC with Rootkit Revealer (you can find it here http://novirusthanks.org/blog/?p=16) and paste here the logs : )

  30. @Andy you did all right and from the HiJackThis Log + Rootkit Revealer Log seem that your computer is clean : )

    -Robert

  31. @Robert – oh wow Thank you for all your help then, i can continue to use my computer worry-free, Again, thanks and Happy New Years :D

  32. FOR ANYONE WITH THIS ISSUE:

    quickest way to get rid of this is COMBOFIX, works even when your system is not running anymore virus scanners.

    this virus took me three hours!

    good luck everyone

  33. Thank you so much Simon, been searching for this answer for hours

  34. Hello. So I’ve been dealing with a virus problem akin to those mentioned here. Its a pesky trojan horse detected by Avast. It causes my computer to shut down frequently and cannot be moved to the chest because it is supposedly being used by other processes, nor can I find it on my computer. I know this may not be the only virus, but its a start. My question for you is – could I simply follow the advice given in the post that i’ve pasted here? Or is that a misdiagnosis on my part?

    The info I get from my avast scan is:
    FILE NAME: C:\Windows\System32\msqpdxmewtfbso.dll
    MALEWARE NAME: Win32:Fasec [tri]

  35. also, I have to admit that my blogging and message board posting experience is limited and I do not know the proper etiquette that comes with them. So i apologize if it is inappropriate to paste a previous post (like I did above), and I will do my best to post properly. I appreciate any help you could extend to me. Thank you so much.

  36. Hi eddie,
    your post is correct : )
    About your Avast log, if the malware is not removed you can follow the info in the previous comments to remove it and remember to delete this file when you are in Safe Mode:

    C:\Windows\System32\msqpdxmewtfbso.dll

    Also if you want try to post an HiJackThis log here so I can analyze it and check if your computer is infected by other malware too.

  37. For some reason my posts are not showing up. . .I really hope you won’t be barraged with them all at once.

    First off, I tried to follow the instructions in the above posts, but couldn’t quite get the ball rolling past step one. I did manage to open up the registry editor and read as much as I could to help me, but could not figure out how to give permissions to regedit32 nor could I figure out how to localize the keys.

    I did manage to get a hijackThis log though!

  38. Here it is. . .It may spread among a couple seperate posts.

  40. Hi eddie,

    I’ve created a video that show how to set permissions for regedit and regedt32 in this article:

    http://novirusthanks.org/blog/?p=799

    View it as it should help you to delete the “protected” keys setting the right permissions.
    About your HiJackThis Logs it seem that your computer is safe : )
    Anyway can you describe wich problem is giving you the computer ?

  41. Hello again Robert. Once again thank you so much for all of your help, it means a lot. The night I last posted I came across the site malwareremoval.com and have just begun trouble shooting to get rid of this thing. Its a site that helps people with their virus woes and serves as a training program for ‘virus vigilantes’ as I like to call them. It seams like a great site, there’s nothing that I should be weary of, is there?

    As far as my issue. . .Avast is my current virus protection program as well as windows defender. I’ve received Avast warnings regarding the virus and am unable to move it to the chest or do anything to it for that matter. I believe the virus prohibits my comp from downloading and installing updates from defender (and probably other programs I am unaware of). It seems as though there are a number of different virus. Though I’ve scene a couple different names the only one I have been able to document is:

    C:\Windows\System32\msqpdxmewtfbso.dll
