During this presentation, we will discover how the Java Card security model is organized upon the real use cases. Next, state-of-the-art attack will be introduced and described to run run illegal instructions in order to obtain the deep secret of the card. Finally, we will discover how informations disclosed on development card can be exploited on cards on production cycle life.
