Abstract

Third-party apps for social networking sites have emerged as a popular feature for online social networks, and are used by millions of users every day. In exchange for additional features, users grant third parties access to their personal data. However, these third parties do not necessarily protect the data to the same extent as social network providers. To automatically analyze the unique privacy and security issues of social networking applications on a large scale, we propose a novel framework, called AppInspect. Our framework enumerates available social networking apps and collects metrics such as the personal information transferred to third party developers. AppInspect furthermore identifies web trackers, as well as information leaks, and provides insights into the hosting infrastructures of apps. We implemented a prototype of our novel framework to evaluate Facebook's application ecosystem. Our evaluation shows that AppInspect is able to detect malpractices of social networking apps in an automated fashion. During our study we collaborated with Facebook to mitigate shortcomings of popular apps that affected the security and privacy of millions of social networking users.
