Hello to all,

I have a friend with a notebook that I guess infected. Every time she connect to the Wifi in my office, I got like 770 alert messages from the APC UPS, in like 2h.

"Informational - Detected an unauthorized user attempting to access the SNMP interface from 192.168.1.134"
 
I scanned the notebook with Malwarebyte, Microsoft Safety scanner, Eset online scanner and other related malware software... the problem still happend when she connect on the network.
 
Somebody have a clue ? I do this scan with Farbar right after used the different cleaning software.
 
Thank you for your help.
 
Chris

Hello @TIChris and :welcome::

While you are waiting for the next qualified/approved malware removal expert helper to weigh in on your topic, and even though you may have run the following Malwarebytes utility, or its subsets, please carefully follow these instructions:

  1. Download the Malwarebytes Support Tool.
  2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.
  3. In the User Account Control (UAC) pop-up window, click Yes to continue the installation.
  4. Run the MBST Support Tool.
  5. In the left navigation pane of the Malwarebytes Support Tool, click Advanced.
  6. In the Advanced Options, click only Gather Logs. A status diagram displays the tool is Getting logs from your computer.
  7. A zip file named mbst-grab-results.zip will be saved to the Public desktop, please attach that file in your next reply to this topic. Please do NOT copy and paste.

For the short time between when you post the diagnostic logs, and when your helper weighs in, please take no further self-directed remedial actions that will invalidate the diagnostic logs you will have posted.

Thank you.

The logs do not indicate that the system is infected. Having a new device on the network can potentially cause devices to log or alert on specific issues.

If you continue to have issues you may need to seek out a Network Consultant to assist.

Well, there is people passing in this office regularly, and we never ever have anything trying to connect to this IP like this. (770 alert message via email = 1 message every 9 second)

during all the time she is connected.

 

The APC UPS is just one interface who inform us in case of high temperature in the office or any power down, they are not mean to detect anything on the network, but they inform us in case of tentative 

of access to the interface via web or snmp mode with wrong credentials (we got the same message when we enter wrong credential in the web interface), the notebook try to connect to this interface (and maybe try to connect to everything in the network).

Maybe a malicious software ?

We can go ahead and scan for malware that might not be obvious.

 

Please download and run the following Kaspersky Virus Removal Tool 2020 and save it to your Desktop.

(Kaspersky Virus Removal Tool version 20.0.10.0 was released on November 9, 2021)

Download: Kaspersky Virus Removal Tool

Select the  image.png  Windows Key and R Key together, the "Run" box should open.

Drag and Drop KVRT.exe into the Run Box.

user posted image

C:\Users\{your user name}\DESKTOP\KVRT.exe will now show in the run box.

add -dontencrypt   Note the space between KVRT.exe and -dontencrypt

C:\Users\{your user name}\DESKTOP\KVRT.exe -dontencrypt should now show in the Run box.

That addendum to the run command is very important, when the scan does eventually complete the resultant report is normally encrypted, with the extra command it is saved as a readable file.

Reports are saved here C:\KVRT2020_Data\Reports and look similar to this report_20210123_113021.klr
Right-click direct onto that report, select > open with > Notepad. Save that file and attach it to your reply.

To start the scan select OK in the "Run" box.

A EULA window will open, tick all confirmation boxes then select "Accept"

In the new window select "Change Parameters"

In the new window ensure all selection boxes are ticked, then select "OK" The scan should now start...

When complete if entries are found there will be options, if "Cure" is offered leave as is. For any other options change to "Delete" then select "Continue"

When complete, or if nothing was found select "Close"

Attach the report information as previously instructed...
 
Thank you

Yes, I was not expecting it to find anything, but no harm in trying.

If you want we can run a generic clean up script on the system. Below is what it typically will do.

 

 

 

 

  1. NOTE:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity.
  2. NOTE: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications may be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed in most, but not all cases.
  3. NOTE: As part of this fix, it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

 

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Discord cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

 

 

Let me know if you're interested in running a clean up script. If you are then please get me a fresh new set of Farbar scan logs.

FRST.TXT
ADDITION.TXT
 

 

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system.
You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). Please attach it to your reply as well.

Thank you

Please run the following fix. @TIChris

Make sure to temporarily disable all real-time security software protection such as Norton 360 / Lifelock

 

NOTE: Please read all of the information below before running this fix.

  • NOTICE: This script was written specifically for this user, for use on this particular machine.
  • Running this on another machine may cause damage to your operating system that cannot be undone.

Once the fix has been completed, please attach the file FIXLOG.TXT to your next reply

Farbar program:   FRSTEnglish.exe

Save the attached file:  FIXLIST.TXT to this folder C:\Users\jessica_bureau\Downloads\

NOTE. It's important that both files, FRSTEnglish.exe, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.

 

Run the Farbar program with Admin rights and press the Fix button just once and wait.

The fix may possibly take up to 60 minutes to complete

If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log named Fixlog.txt in the same folder you ran the Farbar program from. Please attach that log on your next reply.

Please run the following @TIChris

 

SecurityCheck by glax24              

I would like you to run a tool named SecurityCheck to inquire about the current security update status of some applications.

  • Download SecurityCheck by glax24: https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
  • If Microsoft SmartScreen blocks the download, click through to save the file
  • This tool is safe.   Smartscreen is overly sensitive.
  • If SmartScreen blocks the file from running click on More info and Run anyway
  • Right-click  with your mouse on the Securitycheck.exe  and select "Run as administrator"  and reply YES to allow to run & go forward
  • Wait for the scan to finish. It will open a text file named SecurityCheck.txt Close the file.  Attach it with your next reply.
  • You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt
