Beware: Powershell Windows Toolbox that helped install Google Play on Windows 11 is malware

A third-party tool used to install the Google Play Store, among other things, has been found to be malicious. In fact, one of Neowin readers +Eli also appears to have fallen victim to the tool as it seems they installed Play Store using it.

The tool called "Powershell Windows Toolbox" was hosted on GitHub and user LinuxUserGD noticed that the underlying code was cryptic and contained malicious bits. The issue was then raised for the tool by user SuchByte. The Powershell Windows Toolbox has since been removed from GitHub.

Here are all the things the tool claimed to do:

Powershell Windows Toolbox

To start, the software was using Cloudflare workers to load a script. In the How to use section of the tool, the developer had instructed users to run the following command in CLI:

Powershell Windows Toolbox

While the loaded script was doing what was mentioned, obfuscated code was also found here. After de-obfuscating this, it was found that these were PowerShell codes that were loading malicious scripts from Cloudflare workers and files from a GitHub repo of user alexrybak0444, who is likely the threat actor or one of them. These were also reported and removed (archived version here).

After this, the script ultimately creates a Chromium extension which is thought to be the main malicious component of this malware campaign. The payload of the malware seems to be certain links or URLs used to generate revenue via affiliates and referrals through the promotion of some software or some money making schemes distributed via Facebook and WhatsApp messages.

If you happened to install the Powershell Windows Toolbox on your system, you can remove the following components that were created by the tool during the infection:

  • Microsoft\Windows\AppID\VerifiedCert

  • Microsoft\Windows\Application Experience\Maintenance

  • Microsoft\Windows\Services\CertPathCheck

  • Microsoft\Windows\Services\CertPathw

  • Microsoft\Windows\Servicing\ComponentCleanup

  • Microsoft\Windows\Servicing\ServiceCleanup

  • Microsoft\Windows\Shell\ObjectTask

  • Microsoft\Windows\Clip\ServiceCleanup

Also remove the "C:\systemfile" hidden folder which was created by the malicious script during the infestation. And in case you are doing a system restore, make sure to use a restore point that was not done by the Powershell Windows Toolbox itself as it will not remove the malware from the system.

On that note, if you are looking to install Google Play Store using something that is not harmful, check this guide out by Neowin's own Taras Buria, but do keep in mind that Microsoft has put out some really hefty needs for running Android apps on Windows 11.
