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.
Suppose the intended command was:
reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /ve /d "C:\some\portable.dll" /f
A Real Malware Signature: The CLSID 86CA1AA0-34AA-4E8B-A509-50C905BAE2A2 appears in threat intelligence databases. A properly structured reg add command with this ID is used by adware and browser hijackers to register a malicious InprocServer32 (a DLL that loads into other processes). Writing a "how-to" for this would mean publishing an adware installation guide.
InprocServer32 is Dangerous: This key tells Windows to load a specific DLL into any application that creates that COM object. Malware uses it to inject code into Explorer.exe, browsers, or Office.
A normal reg add command looks like this:
reg add "HKCU\Software\Classes\CLSID\CLSID\InprocServer32" /ve /d "C:\Path\file.dll" /f
Your string contains:
If run as-is, this command would fail or cause registry corruption attempts.
When an application attempts to create a COM object using the above CLSID, Windows looks up InprocServer32 in HKCU first (if no admin override). The attacker’s DLL is loaded into the victim process, leading to arbitrary code execution.
Use reg-free COM with manifests, or a virtualization tool like:
Never manually add InprocServer32 keys for “portable” software from untrusted sources.
