Hi all,

 

Name: Spyware.PasswordStealer.MSIL.Generic

Location: C:\Windows\Installer\80f46dc.msi

First of all, thanks in advance to anyone who helps. I know this is a password stealer, but I'm curious, is this a false positive or is it just malware - the odd thing is, I don't download anything unless it's from an official website. Questions are:

- Is this a false positive?

- If not, does this steal previous passwords (saved passwords/autofill etc) or does it only save newly entered passwords (since getting it)

- Could someone IP grab me in let's say a game, and then send me this?

Already quarantined and removed it so cannot do any logs (sorry).

 

Any information you can provide would be gratefully appreciated.

Hello Vyxno and welcome to Malwarebytes,

Continue with the following:

Upload a File to Virustotal

If you do not have Malwarebytes installed do the following:

Download Malwarebytes version 3 from the following link:

https://www.malwarebytes.com/mwb-download/thankyou/

Double click on the installer and follow the prompts. If necessary select the Blue Help tab for video instructions....

When the install completes or Malwarebytes is already installed do the following:

Open Malwarebytes, select > "settings" > "protection tab"

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Go back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Click on the Report tab > from main interface.

  • Accept the EULA (I accept), then click on Scan

Next,

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"
    user posted image
     
  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.


Let me see those logs in your reply...

Thank you,

Kevin....

Apologies, did not notice the file in question had been initially quarantined and secondary deleted from quarantine. MSI files are usually normal and are used in the process of installation.

The file you ask about (80f46dc.msi msi) is probably a database file that is normally used by Windows installer. The msi file will hold information relevant to an appliction, that information is devided into features and components. The components will be holding applicable files for registry data, usual application information and subsequent shortcuts used in the procedure.
The .msi file will also hold the user inferface relevant to the application to be installed, it will also have prerequisites for actions used in a specific order for the installation of the application in question.
So basically the .msi is a list of instructions used by the windows installer, without doubt such .msi files can also have malicious intent aswell as the normal legitimate intent what we expect...
As you`ve removed the .msi file we have no way checking out its intent....

The copy/paste list of scan instructions is what I always request when a system may have been exploited in anyway. If you prefer not to run those scans then I respect your decision...

Thank you,

Kevin...

Yeah, that's the weird thing. I haven't visited any websites outside the usual YouTube, Twitch, Amazon etc. I never click ads and don't even click hyperlinks from friends, so how it got past real-time protection but got detected in a live scan is bizarre.

Had this happen to me. I followed KevinF80's steps and uploaded to virus total i forgot to get a link but it scanned clean through all of the engines. Although the name of Vyxno's .msi file was different from mine. Mine was named 396e66d3.msi so i dont know if this is false positive thing or something else.

Thanks for the reply Sklorton - I do have more reason to believe it being a false positive as there's been no strange behaviour on my computer / none of my passwords have been changed etc (and I have nothing of value - social medias, media streaming sites etc) - posted on /r/Malwarebytes too and hopefully I get an employee to reply. Once again, thank you for your comment.
