Tracks of a rootkit in ntbtlog.txt


Recommended Posts

Hello Malware Byters,

Per the instructions of daledoc1 I am starting a thread here in the hope attracting the attention of an expert malware byter.  daledoc1 has taken me as far as producing the files attached.  His assessment is that my PC is loaded with malware and DUPs (Definitely Unwanted Programs).  The fact of 54,624 lines in the FRST.txt file that look like this:

C:\Users\... Me …\AppData\Local\Temp\10.tmp.exe

C:\Users\... Me …\AppData\Local\Temp\FFFF.tmp.exe

 

is one thing that leads me to share this opinion.

 

Please find six log files attached.

 

Thank you for your help.

Thank you for your fast response.  I would have liked to have been fast to reply but your homework assignment was a substantial one.

That was a substantial homework assignment.  Here are my results.

I downloaded Fixlist.txt and ran FRST64 with it and the FRST.txt file on my desktop.  That produced the 54,715 line FixLog.txt file that is attached.  Mostly it logs the deletion of the long list of FFFF.tmp.exe files in my temp directory.

I next ran Malwarebytes Anti-Malware and produced a log file.  Per your instructions that log file is here:

I next downloaded AdwCleaner and ran that.  Per your instructions I include the log here:

It found some things.  I selected Cleaning to clean them up.  Rather than do a Restart at this point I did a full shutdown and then a boot.  The biggest symptom I have on this PC is that a restart takes about 1 minute 15 seconds while a cold boot takes 8  minutes 15 seconds.  That was the time taken by this cold boot so no improvement there.

I downloaded Sophos Free Virus Removal Tool and launched it.  It took about 4 hours to run.  It found one threat.  That one threat produces a fairly substantial log file.  It is attached below.

After Sophos had completed I did another cold boot.  This one took 8 minutes 17 seconds.  That is about 6 minutes more than was before these troubles.  By the way, it takes 8 minutes to cold boot with no internet connection and 8 minutes to cold boot into safe mode.  If the extra 6 minutes is illicit activity it all happens before any Windows trace technology kicks in.  I have asked in other forums how to trace a cold boot.  So far I have not discovered how to do it.  Or if it is possible.

Thank you for your help.

Kevin,

That is pretty close to how I have been booting.  In msconfig services the only non-Microsoft things that are checked are:

MBAMScheduler

MBAMService

Power Manager Service (Lenovo)

System Update (Listed as Unknown but apparently belongs to Lenovo)

The only Startup objects checked are:

Microsoft Security Client

ThinkPad Power Manager

With just that much checked it takes 8 minutes 17 seconds.

I will disable these five things and do a cold boot.  I will be back after about 8 minutes.

Dudge.

Thanks for those logs, need to upload a couple to VirusTotal to be checked...

Go to http://www.virustotal.com/
 
  • Click the Choose file button
  • Navigate to the file C:\Windows\system32\bi.exe
  • Click the Scan it tab
  • If you get a message saying File has already been analyzed: click Reanalyze file now
  • Copy and paste the results back here please.
  • Repeat the above steps for the following files

C:\Windows\decred.cl

 

Let me know the outcome.....

Here is the first batch for the file bi.exe.  I copied the result from the two tabs Analysis and File Detail.  I have not included the information from Additional Information, Comments, Votes, or Behavior Information.  If you want that also let me know and I will rerun it.  The results are below.  If you don't need both Analysis and File Detail, let me know that also.

FYI, security problems prohibited my navigating from the web to C:\Windows\System32 to find bi.exe.  I copied it to the desktop and uploaded it from there.  I assume that it is ok to do it that way.

I am working on decred.cl now.

Thank you for your help.

Thank you for your help.  I feel that we are making good progress.

The Fixlog.txt file below shows that several files were "moved successfully".  Among those files were the files was the file bi.exe that you had flagged as malicious.  It is interesting to me that another of the files was avgtpx64.sys.  This was interesting to me because these two lines in my ntbtlog.txt file were in at the very beginning of this hunt:

Loaded driver \??\C:\Windows\system32\drivers\avgtpx64.sys
Loaded driver \??\C:\Windows\system32\drivers\bsdriver.sys

bsdriver.sys was flagged by Malwarebytes Anti Malware, but avgptx64.sys was now.  The fact that bsdriver.sys was flagged and that the only two lines in the entire file that wore the figure \??\ made me suspicious of \??\ and of avgtpx64.sys.  And now the last Fixlist.txt file has "moved successfully" the avgtpx64.sys file.  So now I am double suspicious of \??\.  I notice now that Malwarebytes also uses it.  What does it mean?  I have googled it and all I found are other guys that have not gotten an answer.

I notice that you had asked to clobber avgtpx64.sys in your last Fixlist.txt.  What made your suspicious of that?

The log file from Zemana Antimalware is also attached.  It found and apparently deleted two very ugly certificates.  I had checked Quarantine per your instruction but it lists them as having been deleted in the log file.  I have not gone looking for them.

I am very unhappy to report that my cold boot time is 8 minutes 14 seconds.  We have apparently not yet put a dent in its armor.  I hope you are not discouraged.

I am currently running with one startup item checked (ZAM) and one non-Microsoft service running (ZAM Controller Service).

Thank you for your help.

Hello again Dudge,

avgtpx64.sys and its associated service are not malicious those are remnant driver and service from AVG. Because they were still active and running and serving no purpose i listed for removal. I thought maybe it would help with the boot lethargy...

bi.exe is definitely malicious and may have dropped other unwanted malware on your system..

http://www.freefixer.com/library/file/bi.exe-177682/#version-info

Obviously as we make no headway there is still issues we need to find and fix... Continue as follows:

Hello Kevin,

I have run Zoek and RogueKiller per your instruction.  I don't know what all the SkyDrive stuff is in the zoek report.  I have never knowingly signed up for any of that.  Same for SugarSync.  A lot of stuff.  Nothing jumps out at me.

The RogueKillerRpt is also attached.  The only thing that I see that is funny in there is that it is claiming I have two disk drives.  The only disk drive that I have is divided into two partitions.  The C: drive and one that is a set-aside for factory recovery.  Or something similar.  I don't know what that is all about.

Anyway, here it is.  I hope it makes sense to you.  Or if it does not I hope you have more tricks up your sleeve.

Thank you for looking at this.

Dudge.

Certain Lenova systems do come with 2 hard drives, the second one to help speed up the system. I have absolutely no idea what it actually does or how it works, maybe you should check that at a lenova forum... https://forums.lenovo.com/t5/ThinkPad-11e-Windows-E-and-Edge/E531-M2-SSD-Liteonit-LSS-24L6G/td-p/1154637

Regarding SugarSync, it is a cloud file sharing, file sync and online backup service, i`m sure it is not a free service. If you do not need or want it, UNinstall it, i`m sure it will be resource hungry. The same goes for Skydrive....

The RogueKiller log is clean,

Let me know what happens regarding the 2nd HD, also does removal of SugarSync and Skydrive make any difference to the boot time...

I have Uninstalled first Sugarsync and then Skydrive.  After the first uninstall the cold boot time was 8 minutes 14 seconds.  After the second uninstall the cold boot time was 8 minutes 14 seconds.  Very reproducible.   Sugarsync came with the computer as part of Lenovo's marketing strategy.  I never have used it to my knowledge.  Skydrive came with Windows 7 as part of Microsoft's marketing strategy.  I have never knowingly used that.

Apparently, neither uninstall was complete.  A search of the file system shows 40 hits worth of Sugarsync and 22 hits worth of Skydrive.  Can you take me through the eradication of both of those marketing strategies?  It would help cut down the search space for this virus.

I will take the question of the mysterious second "disc" drive to that other forum as you suggest and report back anything that I find out.

I have asked two forums how to trace a cold boot in Windows 7.  On one of them I got instructions on how to trace restarts and silence.  On the other the guy did seem to understand the question but the only ways that he could suggest were to boot over a virtual machine or to use some kind of in-circuit-emulation technology.  It smells like there is no practical way to do it.  I wonder when the ability to trace a cold boot went away.  And if there was any fanfare at that moment.  It seems like that would have been a major triumph for the people who develop and distribute malware.

Thank you.

I neglected to mention that when I went to uninstall Skydrive it told me that it had already been uninstalled and did I want to remove it from the list.  I said yes and after the boot it was gone.  But the 22 hits were still in the file system.  I don't know why it thought it was uninstalled.  I don't recall having uninstalled it earlier.  It make me suspicious of skydrive.

Let me know the outcome of the 2nd HD, what its purpose is...

Run FRST one more time, ensure all boxes are checkmarked under "Whitelist" but only Addition.txt and Shortcut.txt under "Optional scan" Select scan, when done post the new logs....

Thanks,

Kevin....

I just attempted to run FRST64.exe again.  A few seconds after I opened it, it told me that it had updated successfully.  Then I noticed that it had changed languages on me.  If you can tell me what language it is that has skanuj for scan I can tell you what language it is.  I hesitate to run it for fear that it will produce mystery language reports.  Maybe I am paranoid but that seems like suspicious behavior to me.

What do you think?

Thank you.

After searching the web I discover that if I change the name of FRST64.exe to EnglishFRST64.exe and run it, it speaks English.  Wow.  Never have I run into that UI before.  Anyway, it is now speaking English again.  The logs are attached.  In the FRST.txt list there are comments I can make that may or may not be useful.  That LSB.exe listed as a whitelisted file is Lenovo Service Bridge.  It is supposed to make their support better.  I don't know what that means.  Another marketing strategy I suppose.  Does it make sense that it is located in AppData rather than in Program Files?   I have uninstalled it but it lingers on my system.  A file search shows 157 hits.  The LSB executable resides in a folder at the bottom of a big long string that looks more like camouflage than anything else.   That seems to me to be a prime candidate for removal.

I have removed SugarSync but several keys are whitelisted.

There is a tcp/ip address hardcoded in there.

As far as I know I have never used either Chrome or FireFox.

Perhaps you can spot something in one of these.

Thank you.
