Clsid 86ca1aa034aa4e8ba50950c905bae2a2 Inprocserver32 Ve D F Portable — Reg Add Hkcu Software Classes

If you had intended to write a safe, generic article about registering a COM server, a valid version would look like this:

reg add "HKCU\Software\Classes\CLSID\86CA1AA0-34AA-4E8B-A509-50C905BAE2A2\InprocServer32" /ve /d "C:\Path\To\Your\file.dll" /f

Where:

But again: Do not run this with the CLSID you provided, as that is associated with malware. If you had intended to write a safe,

Attackers use this to:

Run this PowerShell command to list all user-mode InprocServer32 keys that point to non-system paths: Where:

Get-ChildItem "HKCU:\Software\Classes\CLSID" -Recurse | Where-Object  $_.PSChildName -eq "InprocServer32"  | ForEach-Object  
    $defaultValue = (Get-ItemProperty $_.PSPath -Name "(default)" -ErrorAction SilentlyContinue).'(default)'
    if ($defaultValue -and ($defaultValue -notlike "C:\Windows\*") -and ($defaultValue -notlike "C:\Program Files*")) 
        Write-Host "SUSPICIOUS: $_ -> $defaultValue" -ForegroundColor Red

Use reg-free COM with manifests, or a virtualization tool like:

Never manually add InprocServer32 keys for “portable” software from untrusted sources. But again: Do not run this with the

This CLSID is not a legitimate Microsoft identifier. Open source threat intelligence (AlienVault OTX, MalwareBazaar) has flagged this GUID as associated with:

When an attacker registers a malicious InprocServer32 under this CLSID (which may impersonate a legitimate COM object like a browser helper), any application that calls that CLSID will load the attacker’s DLL.

Do not run the command in your keyword.
