VBA Obfuscator

VBA Macro obfuscator

Requires ANTLR4 Runtime library 4.8: https://www.antlr.org/download/antlr-runtime-4.8.jar

Uses ANTLR to parse a VBA file and obtain an Abstract Syntax Tree that describes the program. Then walks the tree and changes nodes acording to certain 'morphs', i.e. randomize variables names, encode literals, add useless code, etc.

Input

Sub Something()

Dim A As Integer
A = 100

End Sub

Sub MoreSomethingElses()
Dim B As String
B = "Hello world"
MsgBox B
End Sub

Sub SomethingElse()
    Dim A As Boolean
    A = True
End Sub
