During the last years the evolution of mobile devices was unprecedented. With this increasing popularity of mobile devices and apps, security and privacy concerns have emerged as a salient area of inquiry for researchers. In this thesis, we focus on iOS devices due to, not only the lack of research in this area, but also by the Apple’s restrictions which is far more challenging to investigate compared to Android. More specifically, we study the data leakage and privacy issues posed to iPhone users. This research is aim to gain sensitive information from a mobile device to point out that various iOS apps have data leakage issues. Using the latest forensic tools we present methodologies to acquire data from many renown apps. Our objective is to improve user’s privacy highlighted the missing security mechanisms in order to avoid data and privacy leaks.
