The characteristics listed in the actual article (posted by computerbob: http://www.securelist.com/en/blog/667/The_Mystery_of_the_Duq...) also support this conclusion.

  -Everything is wrapped into objects
  -Function table is placed directly into the class instance and can be
   modified after construction
  -There is no distinction between utility classes (linked lists, hashes) and
   user-written code
  -Objects communicate using method calls, deferred execution queues and
   event-driven callbacks
