Análise de Aplicações Potencialmente Nocivas em Dispositivos com Sistema Operacional Android

Abstract

By the increasing number of mobile devices, which are responsible for a large amountof data, both personal and professional, the need to ensure the protection of such databecomes increasingly imminent. Based on this premise, this work aims to analyze themain characteristics of the potentially harmful applications for mobile devices, based onAndroid, in order to be a starting point for future security solutions and strategies forthese systems. Furthermore, a number of 682 potentially harmful applications were analy-zed following the static analysis method, where features were collected from their sourcecode. From these information, the applications were classified and grouped into families,allowing us to identify the main types of potentially harmful applications in this scenario.Thus, we conclude that it is possible to use data collected from these applications for abetter understanding of their operation and also for modeling of possible threats and vul-nerabilities. Finally, we expect that this work can be useful for further identification, basedon the analysis of its source code, if an application present possibly malicious features
