This thesis evaluates the effects of the GDPR using a technical and human-centric approach. We assess challenges service providers face when they want to design GDPR-proof web applications. On the technical side, we perform two large-scale measurement studies. The first study aims to illuminate third party loading dependencies in web applications. The second study provides a detailed analysis of the information-sharing networks between online adver-tising companies. The human-centric analysis studies how companies implemented the Right to Access and if users can profit from the new right.
Web advertisements are the primary financial source for many online services, but also for cybercriminals. Successful ad campaigns rely on good online profiles of their potential customers. The financial potentials of displaying ads have led to the rise of malware that injects or replaces ads on websites, in particular, so-called adware. This development leads to always further optimized and customized advertising. For these customization's, various tracking methods are used. However, only sparse work has gone into privacy issues emerging from adware. In this paper, we investigate the tracking capabilities and related privacy implications of adware and potentially unwanted programs (PUPs). Therefore, we developed a framework that allows us to analyze any network communication of the Firefox browser on the application level to circumvent encryption like TLS. We use this to dynamically analyze the communication streams of over 16,000 adware or potentially unwanted programs samples that tamper with the users' browser session. Our results indicate that roughly 37% of the requests issued by the analyzed samples contain private information and are accordingly able to track users. Additionally, we analyze which tracking techniques and services are used.
