Do you or have you visited private-chatting[.]com intentionally? Have you done a web search to see if others have input about this site.
What the script is doing is probing your computer to see if you have google, brave or msedge installed, in one of six locations under $searchPaths and if you have their extension installed on those browsers.
Do a search for private-chatting in $env:APPDATA.
Take the string “$env:APPDATA” and enter it into powershell. It will give you a location.
In my case it was C:\Users\someuser\AppData\Roaming
Open Explorer to that location and do the search private-chatting. This might appear in a folder and that folder’s name will tell you where you picked up this script, maybe.
You can check one of the other locations under $searchPaths as well.
You can also check these same locations for ‘.LNK’ no quotes
The LNK files are shortcut files that are associated with Windows and developed by Microsoft Corporation. LNK is an acronym for LINK. LNK files (also known as shell links) are used as a reference to an original file. The script is looking for shortcuts probably to the extension created by private-chatting[.]com
This will help you determine what is going on further.
This script then sends a header to api[.]private-chatting[.]com/update. What they do with it depends on what you can find out from the steps I have given you above.
Again, I did not run any dianostics on it. I do not have your environment to do that with. I only read the script. I am no expert. But you will be able to figure out more if you follow the steps I gave you.
