Class Rex::Exploitation::ObfuscateJS
In: lib/rex/exploitation/obfuscatejs.rb
Parent: Object

Obfuscates javascript in various ways

Methods

new   obfuscate   obfuscate   remove_comments   replace_symbols   sym   to_s  

Public Class methods

new(js)

Initialize an instance of the obfuscator

obfuscate(js, opts = {})

Obfuscates symbols found within a javascript string. The symbols argument should have the following format:

{ 

   'Variables'  => [ 'var1', ... ],
   'Methods'    => [ 'method1', ... ],
   'Classes'    => [ { 'Namespace' => 'n', 'Class' => 'y'}, ... ],
   'Namespaces' => [ 'n', ... ]

}

Make sure you order your methods, classes, and namespaces by most specific to least specific to prevent partial substitution. For instance, if you have two methods (joe and joeBob), you should place joeBob before joe because it is more specific and will be globally replaced before joe is replaced.
