I ran a malware with Trojan.Crypt.Generic.


Recommended Posts

I ran a malware that have Trojan Crypt that can steal user's online account without the user's knowledge. The malware is privateserver.exe inside the Privateserver.rar file. Password for the rar file is "genshin" without the quote. The malware was accidentally excluded from malware detection on Malwarebytes Premium when I ran it. I deleted the malware from directory and recycle bin. I did a 5 times scan in Malwarebytes and nothing gets quarantined. But I still want to take precaution about this so I did a FRST scan. I have included the FRST.txt and Addition.txt.

Hello @Casey9  and  :welcome:

 

My name is MKDB and I will assist you.

 

 

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow the steps in the given order and post back the log files.
  • Please attach all log files into your post.
  • 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.
  • Searching, detecting and removing malware isn't instantaneous and there is no guarantee to repair every system.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Please be patient and stick with me until I give you the "all clear".
  • Only run the tools I guide you to. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Cracked or hacked or pirated programs are not only illegal, but also will make a computer a malware victim. Having such programs installed, is the easiest way to get infected. It is the leading cause of ransomware encryptions. It is at times also big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
  • As English is not my native language, please do not use slang or idoms. It may be hard for me to understand.
  • If you do not respond within 4 days, your topic will be closed. If you are away for a longer time, please let me know.

 

 

Please run AdwCleaner and ESET for me first. Thank you!

 

 

Step 1

Please download AdwCleaner and save it to your desktop.

  • Double-click to run it.
  • Accept the End User License Agreement.
  • Click Scan Now.
  • When finished, if items are found please click Next / Quarantine.
  • Maybe your PC will be rebooted, AdwCleaner will be opened automatically.
  • Click View Log File.
  • AdwCleaner will open one log (AdwCleaner[Cxx].txt).
  • Please paste the log to your next reply.

 

 

 

Step 2

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

I suspects that this malware "privateserver.exe" is meant for stealing account for Genshin Impact online game. I received a 2fa notification in my phone that someone from United States wants to log in to my Facebook account but I am from APAC. That Facebook account is linked/binded to the in game account for Genshin Impact. I already blocked the authorization and changed my Facebook password. Should I fully uninstall the game? I am scared the possibility is that the malware did nothing to the registry but injecting something to the game folder in my drive. From the ESET scan, I do have some cracked games but I can guarantee that does not harm my pc. Since I bought all the cracked games from a legitimate seller from Shopee with high good sales rating. But there's also a possibility that something bad is in the registry because of this malware. I also checked that there is no suspicious startup software using Autorun and task manager. I still willing to follow a last resort which is performing clean install of Windows 11(current windows).

Thank you @Casey9 for those logfiles and the provided information.

I suggest to fully uninstall the game.

We will run a general cleanup fix with FRST to remove some leftovers and check windows system files. This may take some time (>10 minutes), please be patient during the fix and do not interfere!

 

 

Step 1

  • Please download the attached fixlist.txt file and save it to the location where you ran FRST from ( C:\Users\casey\Downloads\ ).

Note: It's important that both files, FRST and fixlist.txt are in the same location or the fix will not work.

  • Close all open programs and save your work.
  • Run FRST again.
  • Press the FIX button only once and wait. Please be patient and do not interfere, even if FRST does not respond for some time. That's nothing to worry about.
  • Please note: This Fix will remove all temporary files and empty recycle bin.
  • If the tool needs a restart, please make sure you let the system restart normally and let the tool complete its run after restart.
  • FRST will create one log now (Fixlog.txt) in the same directory the tool is run.
  • Please attach this logfile to your next reply.

@MKDB

I did the Step 1 using the fixlist.txt in FRST. After system restarted, two firewall notification popped out. I'll wait for your confirmation to allow access or cancel these two. I have included the Fixlog.txt. But I have not fully uninstall the game. I will disconnect any network from my laptop for now and wait for email notification from my phone for your reply. Please tell me if I need to uninstall the game first before executing the fix using FRST so I can repeat the process.

Thank you @Casey9, well done!

Regarding those firewall security settings, you should choose Allow access for private network.

It doesn't matter if you do the uninstall or the fix first. Just uninstall the game now and reboot your system. There is not need to run the fix again.

 

Let me know when those things are done.

Another check @Casey9.

 

Step 1

The Microsoft Safety Scanner (MSS) is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system.

  • The download links & the how-to-run-the tool are at this link at Microsoft.
  • Please let me know the results of this scan.
  • Run a Quick Scan.
  • The log is named MSERT.log.
  • The log will be at%SYSTEMROOT%\debug\msert.log which in most cases is

C:\Windows\debug\msert.log

  • Please attach that log with your next reply.

Thank you very much @Casey9.

 "VirTool:Win32/DefenderTamperingRestore" is a configuration of the Defender that was not optimal for security, not malware itself. So no need to worry.

 

To sum up, beside your cracked software (which I would uninstall/remove) your system looks clean, means that I can't see active malware on your system.

From my point of view, it is not absolutely necessary for you to reinstall your system.

 

 

Thank you for your cooperation, we're done. 😃

 

Final Step

  • Right-Click on FRST64 and choose Rename.
  • Rename FRST64 into Uninstall.
  • Run Uninstall.
  • FRST and it’s files/folders will be deleted.
  • If the tool needs a restart, please make sure you let the system restarts normally.

 

 

 

 

A few final recommendations:

  1. Recommend using a Password Manager for all websites, etc. that require a password. Never use the same password on more than one site.
