Abstract

This paper presents a method to inject a mutable Java Card applet into a smart card. This code can on demand parse the memory in order to search for a given pattern and eliminate it. One of these key features is to bypass security checks or retrieve secret data from other applets. We evaluate the countermeasures against this attack and we show how some of them can be circumvented and we propose to combine this attack with others already known.
