Getting "Compromised" and "Trojan" blocked alerts for a couple weeks now


Recommended Posts

Hi,

I've been getting a Compromised and Trojan blocked toasts for a couple of weeks now.

I've port forward for a Minecraft server in my router (the server as not been online for too long, only when me and my girlfriend wants to play) and since then I'm getting those alerts from mb.

Likewise, I wasn't paying too much attention to it because mb was blocking the entries, but it's starting to getting really annoying and more frequent. I don't want to close the ports because I want to play with her, but I at this point I don't even know if it's a false positive or not.

I can send the reports if needed, just tell me what to do, please.

Hello @n0ia96 and :welcome:

 

 

Please run the following steps and post back the logs as an attachment when ready.
Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
If you still have trouble downloading the software please click on Reveal Hidden Contents below for examples of how to allow the download.

When downloading with some browsers you may see a different style of screens that may block FRST from downloading. The program is safe and used hundreds of times a week by many users.

Example of Microsoft Edge blocking the download

STEP 01

  • If you already have Malwarebytes installed then open Malwarebytes and click on the Scan button. It will automatically check for updates and run a Threat Scan.
  • If you don't have Malwarebytes installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and select Scan and let it run.
  • Once the scan is completed make sure you have it quarantine any detections it finds.
  • If no detections were found click on the Save results drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If there were detections then once the quarantine has completed click on the View report button, Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If Malwarebytes won't run then please skip to the next step and let me know in your next reply that the scanner would not run.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

  • Double-click to run the program
  • Accept the End User License Agreement.
  • Wait until the database is updated.
  • Click Scan Now.
  • When finished, if items are found please click Quarantine.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. Attach or Copy its content into your next reply.

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the 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). If you've, run the tool before you need to place a check mark here each time
  • Please attach the Additions.txt log to your reply as well.
  • On your next reply, you should be attaching frst.txt and additions.txt to your post, every time.

 

Thanks

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.
NOTE. It's important that both files, FRST or FRST64, 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.

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.

Run FRST or FRST64 and press the Fix button just once and wait.
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 on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1:  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. Depending on the speed of your computer this fix may take 30 minutes or more.

NOTE-2: 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 will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The use of an external password manager is highly recommended instead of using your browser to store passwords.

NOTE-3: 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
  • Flash Player 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.

DS4Windows is a software that allows you to emulate Dualsense's and Dualshock's (PS5 controllers and PS4 controllers) on your PC. I'd guess that's something to do with that because of the name.

Thank you so much for your time!

Let me have you go ahead and run the following 3rd party AV scanner.

 

 

Let me have you run a different scanner to double-check. I don't expect it to find anything, but no harm in checking.

I would suggest a free scan with the ESET Online Scanner

Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe

  • It will start a download of "esetonlinescanner.exe"
  • Save the file to your system, such as the Downloads folder, or else to the Desktop.
  • Go to the saved file, and double click it to get it started. 
  • When presented with the initial ESET options, click on "Computer Scan".
  • Next, when prompted by Windows, allow it to start by clicking Yes 
  • When prompted for scan type, Click on Full scan 
  • Look at & tick  ( select )   the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click on the Start scan button.
  • Have patience.  The entire process may take an hour or more. There is an initial update download.
  • There is a progress window display.
  • You should ignore all prompts to get the ESET antivirus software program.   ( e.g. their standard program).   You do not need to buy or get or install anything else.
  • When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.
  • Click The blue “Save scan log” to save the log.
  • If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at the bottom).
  • Press Continue when all done.  You should click to off the offer for “periodic scanning”.

 

Note: If you do need to do a File Restore from ESET please follow the directions below

[KB2915] Restore files quarantined by the ESET Online Scanner version 3

Thanks

Thank you. Please post back the FIXLOG.txt file as an attachment.

Sorry about that, I've attached it now.

Also, while ESET Online Scanner was running I got another notification from Malwarebytes blocking another “Compromised”. But this time it was a different one, it was from AnyDesk (a program I use to control and fix things on my gf's computer, it's like TeamViewer but better), but I guess this one was a false positive.

Also, I've attached a screenshot of the recent activity from my Malwarebytes, all different IP's getting compromised. From all those, only two are from AnyDesk.

Those are inbound blocks stopping Remote Desktop Protocol attacks from the original log. So, Malwarebytes is doing its job. Normally these type of blocks will go away within a couple days on their own.

Let's wait and see what ESET find, but you're not supposed to be using any web browser or other programs while the scan is going on.

Finally, after almost 2h it's done!

While it was scanning, I noticed a small "(?)" that saying that I could use the computer without any restrictions while it was scanning, but after I saw your message, I closed my browser and let the program work.

Here are the results, it actually found something:

You can do the following to ensure that your Router is safe and secure if you own it. If you rent it from your ISP you may not be able to reset it.

 

Please ensure that you have the user manual for your router. Then perform a factory reset.

How To Reset Your Router
https://setuprouter.com/networking/how-to-reset-your-router/

 

Depending on one's preferences and the Router's capabilities please consider the following.

  • Disable acceptance of ICMP Pings
  • Change the Default Router password using a Strong Password
  • Use a Strong WiFi password on WPA2  using AES encryption or Enable WPA3 if it is an option.
  • Disable Remote Management
  • Create separate WiFi networks for groups of devices with similar purposes to prevent an entire network of devices from being compromised if a malicious actor is able to gain unauthorized access to one device or network. Example: Keep IoT devices on one network and mobile devices on another.
  • Change the network name (SSID).  Do not use your; Name, Postal address, or other personal information.  Make it unique or whimsical and known to your family/group.
  • Is the Router Firmware up-to-date?  Updating the firmware mitigates exploitable vulnerabilities.
  • Specifically set Firewall rules to BLOCK;   TCP and UDP ports 135 ~ 139, 445, 1234, 3389 and 5555
  • Document passwords created and store them in a safe but accessible location.
