Security Code Smells in Android ICC
Android Inter-Component Communication (ICC) is complex, largely
unconstrained, and hard for developers to understand. As a consequence, ICC is
a common source of security vulnerability in Android apps. To promote secure
programming practices, we have reviewed related research, and identified
avoidable ICC vulnerabilities in Android-run devices and the security code
smells that indicate their presence. We explain the vulnerabilities and their
corresponding smells, and we discuss how they can be eliminated or mitigated
during development. We present a lightweight static analysis tool on top of
Android Lint that analyzes the code under development and provides just-in-time
feedback within the IDE about the presence of such smells in the code.
Moreover, with the help of this tool we study the prevalence of security code
smells in more than 700 open-source apps, and manually inspect around 15% of
the apps to assess the extent to which identifying such smells uncovers ICC
security vulnerabilities.Comment: Accepted on 28 Nov 2018, Empirical Software Engineering Journal

AndroShield:automated Android applications vulnerability detection, a hybrid static and dynamic analysis approach
The security of mobile applications has become a major research field which is associated with a lot of challenges. The high rate of developing mobile applications has resulted in less secure applications. This is due to what is called the “rush to release” as defined by Ponemon Institute. Security testing—which is considered one of the main phases of the development life cycle—is either not performed or given minimal time; hence, there is a need for security testing automation. One of the techniques used is Automated Vulnerability Detection. Vulnerability detection is one of the security tests that aims at pinpointing potential security leaks. Fixing those leaks results in protecting smart-phones and tablet mobile device users against attacks. This paper focuses on building a hybrid approach of static and dynamic analysis for detecting the vulnerabilities of Android applications. This approach is capsuled in a usable platform (web application) to make it easy to use for both public users and professional developers. Static analysis, on one hand, performs code analysis. It does not require running the application to detect vulnerabilities. Dynamic analysis, on the other hand, detects the vulnerabilities that are dependent on the run-time behaviour of the application and cannot be detected using static analysis. The model is evaluated against different applications with different security vulnerabilities. Compared with other detection platforms, our model detects information leaks as well as insecure network requests alongside other commonly detected flaws that harm users’ privacy. The code is available through a GitHub repository for public contribution
Ghera: A Repository of Android App Vulnerability Benchmarks
Security of mobile apps affects the security of their users. This has fueled
the development of techniques to automatically detect vulnerabilities in mobile
apps and help developers secure their apps; specifically, in the context of
Android platform due to openness and ubiquitousness of the platform. Despite a
slew of research efforts in this space, there is no comprehensive repository of
up-to-date and lean benchmarks that contain most of the known Android app
vulnerabilities and, consequently, can be used to rigorously evaluate both
existing and new vulnerability detection techniques and help developers learn
about Android app vulnerabilities. In this paper, we describe Ghera, an open
source repository of benchmarks that capture 25 known vulnerabilities in
Android apps (as pairs of exploited/benign and exploiting/malicious apps). We
also present desirable characteristics of vulnerability benchmarks and
repositories that we uncovered while creating Ghera.Comment: 10 pages. Accepted at PROMISE'1
