Sensitive Data Leakage Detection in Pre-Installed Applications of Custom Android Firmware

14:41 26/06/2018

There are many custom Android firmware (custom ROMs) which are shared on the Internet. Several recent studies aim their efforts at analyzing pre-installed applications in these firmware. However, they analyzed separate pre-installed applications. In this study we propose a system, uitXROM, to detect sensitive data leakage in custom Android firmware by analyzing relationships of pre-installed applications. The experimental results show that the system can detect all sensitive data leakage in our custom Android firmware. Secondly, it detects several pre-installed applications which leak sensitive data from 290 custom ROMs downloaded from the Internet.

The abuse of prescription medications has become a severe public health crisis fueled by limited coordination and oversight across healthcare systems. Current frameworks lack interoperability between doctors, pharmacies, and regulators, enabling abusive practices like doctor shopping and pharmacy hopping. To address these issues, this research proposes Medichain, a novel multichain-based...
