One of the major Android security mechanisms for enforcing restrictions on the core facilities of a device that an app can access is permission control. However, there is an enormous amount of risk with regards to granting permissions since 97% of malicious mobile malware targets Android. As malware is becoming more complicated, recent research proposed a promising approach that checks implemented app behaviour against advertised app behaviour for inconsistencies. In this paper, we investigate such inconsistencies by matching the permission an app requests with the natural language descriptions of the app which gives an intuitive idea of user expected behaviour of the app. Then, we propose exploiting an enhanced app description to improve malware detection based on app descriptions and permissions. To evaluate the performance, we carried out various experiments with 56K apks. Our proposed …
