An Empirical Study on Android-related Vulnerabilities
Mobile devices are used more and more in everyday life. They are our cameras,
wallets, and keys. Basically, they embed most of our private information in our
pocket. For this and other reasons, mobile devices, and in particular the
software that runs on them, are considered first-class citizens in the
software-vulnerabilities landscape. Several studies investigated the
software-vulnerabilities phenomenon in the context of mobile apps and, more in
general, mobile devices. Most of these studies focused on vulnerabilities that
could affect mobile apps, while just few investigated vulnerabilities affecting
the underlying platform on which mobile apps run: the Operating System (OS).
Also, these studies have been run on a very limited set of vulnerabilities.
In this paper we present the largest study at date investigating
Android-related vulnerabilities, with a specific focus on the ones affecting
the Android OS. In particular, we (i) define a detailed taxonomy of the types
of Android-related vulnerability; (ii) investigate the layers and subsystems
from the Android OS affected by vulnerabilities; and (iii) study the
survivability of vulnerabilities (i.e., the number of days between the
vulnerability introduction and its fixing). Our findings could help OS and apps
developers in focusing their verification & validation activities, and
researchers in building vulnerability detection tools tailored for the mobile
world
Towards a threat assessment framework for apps collusion
App collusion refers to two or more apps working together to achieve a malicious goal that they otherwise would not be able to achieve individually. The permissions based security model of Android does not address this threat as it is rather limited to mitigating risks of individual apps. This paper presents a technique for quantifying the collusion threat, essentially the first step towards assessing the collusion risk. The proposed method is useful in finding the collusion candidate of interest which is critical given the high volume of Android apps available. We present our empirical analysis using a classified corpus of over 29,000 Android apps provided by Intel SecurityTM
