FSquaDRA is a detection tool designed to identify repackaged Android applications through similarity analysis. The tool operates on the principle that repackaged applications typically maintain the visual appearance and functionality of their original counterparts while potentially containing malicious modifications. It computes Jaccard similarity coefficients by analyzing the set of file digests contained within Android package (APK) files. The detection process leverages pre-computed digests that are generated during the Android application signing process, which significantly reduces the computational overhead required for APK comparison operations. This approach allows for faster analysis compared to methods that require real-time digest computation. FSquaDRA was developed at the University of Trento and the research findings were presented at the 28th Annual IFIP WG 11.3 Working Conference on Data and Applications Security and Privacy. The tool can be built as a JAR file for deployment and execution.
