TLDR
Using TaintDroid to monitor the behavior of 30 popular third-party Android applications, this work found 68 instances of misappropriation of users' location and device identification information across 20 applications.Abstract:
Today's smartphone operating systems frequently fail to provide users with adequate control over and visibility into how third-party applications use their private data. We address these shortcomings with TaintDroid, an efficient, system-wide dynamic taint tracking and analysis system capable of simultaneously tracking multiple sources of sensitive data. TaintDroid provides realtime analysis by leveraging Android's virtualized execution environment. TaintDroid incurs only 14% performance overhead on a CPU-bound micro-benchmark and imposes negligible overhead on interactive third-party applications. Using TaintDroid to monitor the behavior of 30 popular third-party Android applications, we found 68 instances of potential misuse of users' private information across 20 applications. Monitoring sensitive data with TaintDroid provides informed use of third-party applications for phone users and valuable input for smartphone security service firms seeking to identify misbehaving applications.read more

Identifying Personal Information in Internet Traffic
TL;DR: A novel method is developed that can automatically discover various types of PI carried within protocol fields of network traffic; the method includes techniques to filter out potential "containers" that do not actually carry PI and extend the set of containers initially found with additional ones.

Model-Checking for Android Malware Detection
Fu Song,Tayssir Touili +1 more
TL;DR: An automatic and scalable approach to analyze Android applications and identify malicious applications, which consists of modeling an Android application as a PushDown System (PDS), succinctly specifying malicious behaviors in Computation Tree Logic (CTL) or Linear Temporal Logic (LTL), and reducing the Android malware detection problem to CTL/LTL model-checking for PDSs.

A cloud-based architecture to crowdsource mobile app privacy leaks
TL;DR: A cloud-based system that operates under a crowdsourcing logic, with the aim to provide i) a real-time privacy-flow tracking service, ii) a collaborative infrastructure for exchanging information related to apps' privacy exposure level, and iii) potentially a behavior-driven detection mechanism in an effort to take advantage of the crowdsourcing data to its maximum efficasy.
