Reflective .NET Assembly Load via PowerShell by protocal.cjs
Detects PowerShell executing a reflective .NET assembly load, indicated by keywords like 'Reflection.Assembly', 'Load', and 'byte' in the command line. The detection is further refined by looking for 'Extension.SubRoutine', 'Run2', or the C2 domain 'hellolargeworld.com' in the command line, and specifically targets instances where the initiating process is 'node.exe'. This behavior is indicative of the 'protocal.cjs' backdoor.
