In this paper, we investigate using obfuscation as a security-through-obscurity approach to hide app code vulnerabilities in Android apps. Obfuscation refers to a set of techniques that change the syntax of the code but preserve its semantics. This way, the app maintains the same runtime ...
Code obfuscation figures among one of the most preferred app code protection and mobile application security techniques to guard against application hacking.
We propose a code recognition technique that is resilient against common code transformations and that excels in identifying code fragments and libraries in Android applications. Our method relies on obfuscation-resilient features from the Abstract Syntax Tree of methods and uses them in combination with...
You do not have to invoke ProGuard manually as it is integrated into the Android build system. Now that you've fully set up your proguard.cfg and build.properties file, ProGuard runs only when you build your application in release mode. Other Obfuscation Tools If you are using another progra...
integration with Gradle. This plugin allows you to build different versions of your app (i.e. paid and unpaid, custom builds for different Android devices) while still leveraging the same code base. It also enables signing your APK and code obfuscation support too, as well asmany other ...
We have also included existing methods which have been applied in other OS environments but can be applied on Android application source code. The prevailing code obfuscation methods [8] as outlined in Fig. 8 are discussed below. 3.2.1 Constant data obfuscation As the name suggests, this ...
Android packerCode virtualizationCompilerLLVMInfringing intellectual property by reverse analysis is a severe threat to Android applications. By replacing the program instructions with virtual instructions that an adversary is unfamiliar with, code obfuscation based on virtualization is a promising way of ...
