They should work. Works for all cores of your host system. Also you can download ESXi from here.
We can do this by experimenting with .config files.
Many defenders catch/detect files that are renamed, they do this by matching Original Filename to Process Name
In this example, we don't have to rename anything. We simple coerce a trusted signed app to load our Assembly.
We do this by directing the application to read a config file we provide.

| DynWin32-ReverseShell.ps1 is a reverse shell based on dynamically looked up Win32 API calls. | |
| The script uses reflection to obtain access to GetModuleHandle, GetProcAddress and CreateProcess. | |
| Afterwards it uses GetModuleHandle and GetProcAddress to resolve the required WSA functions | |
| from ws2_32.dll. | |
| This script should be used for educational purposes only (and maybe while playing CTF :D). | |
| It was only tested on Windows 10 (x64) and is probably not stable or portable. It's only | |
