Towards an understanding of the impact of advertising on data leaks

Recent investigations have determined that many Android applications in both official and non–official online markets expose details of the user's mobile phone without user consent. In this paper, for the first time in the research literature, we provide a full investigation of why such applications leak, how they leak and where the data is leaked to. In order to achieve this, we employ a combination of static and dynamic analysis based on examination of Java classes and application behaviour for a data set of 123 samples, all pre–determined as being free from malicious software. Despite the fact that anti–virus vendor software did not flag any of these samples as malware, approximately 10% of them are shown to leak data about the mobile phone to a third–party; applications from the official market appear to be just as susceptible to such leaks as applications from the non–official markets.
