Abstract

In Man-At-The-End (MATE) attacks, software apps run on a device under full control of the attackers: they can violate the intellectual property of the app by means of malicious reverse engineering, software piracy, and software tampering. Obfuscation is a technique that is widely adopted by developers to mitigate this problem. Obfuscation increases complexity of software code, by obscuring the structure of code and data in order to thwart the reverse engineering process. However, it is possible to reverse engineer obfuscated code with time, determination and the right tools. In general, there is no accepted methodology to determine the strength of obfuscated code; however resilience is often considered a good metric as it indicates the percentage of obfuscated code that cannot be removed by automated de-obfuscation tools. We introduce a novel approach to measure the resilience of obfuscated C code using program slicing.
