PowerShell Reflective .NET Assembly Load by Node.js
Detects PowerShell executing a reflective .NET assembly load, potentially indicative of a backdoor, initiated by a Node.js process. The detection specifically looks for keywords related to .NET Reflection, assembly loading, byte arrays, and a specific C2 domain (hellolargeworld.com:443) or invocation method (Extension.SubRoutine.Run2) within the PowerShell command line. The initiating process is expected to be 'node.exe'.
