Infected by trojan(s)

[Henrik2012]

Hello,

I've been having some trouble in the last day or so. One of the recurring bugs went by the name of Trojan:win32/ramnit.D, which sounded like bad news to say the least when I googled it.

It's calmed down in the last few hours after running various scans and over several reboots, as well as the steps required for posting logs here, but I expect it will still be there.

I'm wondering if someone would be able to help and advise whether there's anything that can be done, or if it will have to be a clean reinstall?

I've tried to follow all the steps in the readme, hopefully these attached logs are ok;

Thanks, any help is much appreciated.

I want you to run TDSSKiller so refer to the below for how to do so.

TDSSkiller - How to run


Please also download MBRCheck to your desktop

• Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
• It will show a Black screen with some information that will contain either the below line if no problem is found:
  • Done! Press ENTER to exit...
• Or you will see more information like below if a problem is found:
  • Found non-standard or infected MBR.
  • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
• Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
• MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.

Additionally....


Run this and attach the results.

Using ESET's Online Scanner

[Henrik2012]

Hi Kestrel, thanks for helping.

Please find attached the TDDSKiller and MBRcheck logs. The ESET scan picked up no threats, and I couldn't see an option to create any log, only to finish.

[Kestrel13!]

Run the ESET scan again, and let me know what types of infection it is finding. Is it Ramnit specifically?

I am not seeing alot to do from your logs.


Java(TM) 6 Update 26 <-- uninstall outdated Java.


Delete these files.

• C:\Users\Kenny\AppData\Local\qekealau.log
• C:\Users\Kenny\AppData\Local\sstbalon.log
• C:\Users\Kenny\AppData\Local\uehfloqb.log
• C:\Users\Kenny\AppData\Local\wjsoxojm.log

Now Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

REGEDIT4

[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{5C255C8A-E604-49b4-9D64-90988571CECB}]
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{FDD3B846-8D59-4ffb-8758-209B6AD74ACC}]

Make sure that you tell me if you receive a success message about adding the above
to the registry. If you do not get a success message, it definitely did not work.


Now run the C:\MGtools\Getlogs.bat and attach the new resulting C:\MGlogs.zip.

[Henrik2012]

Thanks for getting back to me so quickly Kestrel13!

I ran ESET again and it did identify something this time - Java/exploit.Agent.NBH trojan, details of which are in the attached log.

Ramnit.D has never appeared on ESET, it was only picked up on Microsoft Security Essentials on Monday (Apr 30), and seemed to keep reappearing after being removed and the pc rebooted, but only for a few hours. Since then, there's been nothing like that, the only unusual thing is my internet connection is quite slow, but obviously that could be totally unrelated.

If it helps, the names of the stuff that MSE was originally picking up during that spell on Monday were as follows;
Trojan:Win32/Ramnit.D (a dozen or so times)
Exploit:Java/CVE-2010-0840.PG
Exploit:Java/CVE-2011-3544.A
Trojan:Downloader.Java/open connection.PK
Trojan:JS/Redirector.GQ
Trojan:JS/BlacoleRef.G

Ok, I followed your instructions, uninstalled Java, removed the specified files and ran fixME.reg. It did appear to be successful ("The keys and values contained in C:\Users\Kenny\Desktop\fixME.reg have been successfully added to the register"). It only seemed to chang two of the files in the folder, GetUNkey.txt, and runkeys.txt, so hopefully I've done it correctly.

[Kestrel13!]

Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

• O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)
• O2 - BHO: (no name) - {FDD3B846-8D59-4ffb-8758-209B6AD74ACC} - (no file)
• O18 - Protocol: vsharechrome - {3F3A4B8A-86FC-43A4-BB00-6D7EBE9D4484} - (no file)

After clicking Fix exit HJT.


Now we need to use ComboFix by sUBs

• Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
  • If it is not on your Desktop, the below will not work.
• Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
• If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
• Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:

KILLALL::

File::
C:\Users\Kenny\AppData\Local\qekealau.log
C:\Users\Kenny\AppData\Local\sstbalon.log
C:\Users\Kenny\AppData\Local\uehfloqb.log
C:\Users\Kenny\AppData\Local\wjsoxojm.log
Registry::
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{5C255C8A-E604-49b4-9D64-90988571CECB}]
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{FDD3B846-8D59-4ffb-8758-209B6AD74ACC}]

• Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
• At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
• You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
• Now use your mouse to drag CFscript.txt on top of ComboFix.exe
  
  
  
  
• Follow the prompts.
• When it finishes, a log will be produced named c:\combofix.txt
• I will ask for this log below

Note:

Do not mouseclick combofix's window while it is running. That may cause it to stall.

If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.


Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now!

[Henrik2012]

Hi again Kestrel13!

I followed your instructions and it all seemed to go ok. Please find attached the combofix log and MGtools zip as requested.

Everything seems to be running fine thanks to your good self. I've had no problems at all in recent days (touch wood!).

D'you think i've maybe been lucky and it was a mild infection, not actually the real ramnit, or something like that?

[Kestrel13!]

Uninstall the below.

• Ask Toolbar
• Java(TM) 6 Update 26

Reboot your machine and install the most current and up to date version of Java available here at the below link:

Java Runtime 6

If it helps, the names of the stuff that MSE was originally picking up during that spell on Monday were as follows;
Trojan:Win32/Ramnit.D (a dozen or so times)

You don't know specifically where it was finding the infection do you?

[Henrik2012]

Hi again,

That's the new java installed. I'd already uninstalled the old one and the ask toolbar during the last week, they're not on the uninstall list from control panel any more. Are there remnants of them elsewhere that i'll need to delete manually or something?

The information on the infection was as follows;

Name:Trojan:Win32/Ramnit.D
ID: 2147645306
Severity: Severe
Category: Trojan
Path: process:_pid: (various 4 digit numbers)
Detection Origin: Unknown
Detection Type: Heuristics
Detection Source: System
User: NT AUTHORITY\SYSTEM
Process Name: C:\Users\Kenny\Appdata\Local\lwpbamc\tdennmlc.exe

If you need any more info, just let me know.

Cheers.

[Kestrel13!]

OK then.

If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /uninstall
     • Notes: The space between the combofix" and the /uninstall, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
7. Go to add/remove programs and uninstall HijackThis.
8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
   related to MGtools and some other items from our cleaning procedures.
9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
   • Refer to the cleaning procedures pointed to by step 7 of the READ ME
     for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore to create a new clean Restore Point.
10. After doing the above, you should work thru the below link:
    • How to Protect yourself from malware!

Hey again Kestrel13!

Ok, everything's still fine after a couple of weeks, and i've followed the final steps in the last post, so I guess I should be ok?

Thank you very much for all your help, it's been much appreciated. I'll try my best not to have to bother you again

All the best,

Kenny. :

You are welcome, Kenny.
