  • Security Considerations Around the Usage of Client-Side Storage Apis
    Security considerations around the usage of client-side storage APIs Stefano Belloro (BBC) Alexios Mylonas (Bournemouth University) Technical Report No. BUCSR-2018-01 January 12 2018 ABSTRACT Web Storage, Indexed Database API and Web SQL Database are primitives that allow web browsers to store information in the client in a much more advanced way compared to other techniques such as HTTP Cookies. They were originally introduced with the goal of enhancing the capabilities of websites, however, they are often exploited as a way of tracking users across multiple sessions and websites. This work is divided in two parts. First, it quantifies the usage of these three primitives in the context of user tracking. This is done by performing a large-scale analysis on the usage of these techniques in the wild. The results highlight that code snippets belonging to those primitives can be found in tracking scripts at a surprising high rate, suggesting that user tracking is a major use case of these technologies. The second part reviews of the effectiveness of the removal of client-side storage data in modern browsers. A web application, built for specifically for this study, is used to highlight that it is often extremely hard, if not impossible, for users to remove personal data stored using the three primitives considered. This finding has significant implications, because those techniques are often uses as vector for cookie resurrection.

Supervisor: Björn Johnsson, [email protected] Examiner: Per Andersson, [email protected] Abstract Team collaboration software is a great way for people to share their work. But often the need arises for accessing the work while on the go using limited net- work connections. The ongoing development in the area of HTML5 and web applications has opened up many new possibilities, especially for storing data locally. In this thesis we extensively test and compare these new solutions to find the best alternative. Along with testing and comparing techniques for database repli- cation and synchronization we hope to combine the two, enhancing the user experience by optimizing the team collaboration web application. Keywords: Database, replication, HTML5, local storage, optimization ii Acknowledgements We would like to thank the people over at RefinedWiki for providing us with a great work- ing environment, along with feedback and support.
