AdSplit: Separating smartphone advertising from applications
A wide variety of smartphone applications today rely on third-party
advertising services, which provide libraries that are linked into the hosting
application. This situation is undesirable for both the application author and
the advertiser. Advertising libraries require additional permissions, resulting
in additional permission requests to users. Likewise, a malicious application
could simulate the behavior of the advertising library, forging the user's
interaction and effectively stealing money from the advertiser. This paper
describes AdSplit, where we extended Android to allow an application and its
advertising to run as separate processes, under separate user-ids, eliminating
the need for applications to request permissions on behalf of their advertising
libraries.
We also leverage mechanisms from Quire to allow the remote server to validate
the authenticity of client-side behavior. In this paper, we quantify the degree
of permission bloat caused by advertising, with a study of thousands of
downloaded apps. AdSplit automatically recompiles apps to extract their ad
services, and we measure minimal runtime overhead. We also observe that most ad
libraries just embed an HTML widget within and describe how AdSplit can be
designed with this in mind to avoid any need for ads to have native code
Mobile Application Security Platforms Survey
Nowadays Smartphone and other mobile devices have become incredibly important in every aspect of our life. Because they have practically offered same capabilities as desktop workstations as well as come to be powerful in terms of CPU (Central processing Unit), Storage and installing numerous applications. Therefore, Security is considered as an important factor in wireless communication technologies, particularly in a wireless ad-hoc network and mobile operating systems. Moreover, based on increasing the range of mobile application within variety of platforms, security is regarded as on the most valuable and considerable debate in terms of issues, trustees, reliabilities and accuracy. This paper aims to introduce a consolidated report of thriving security on mobile application platforms and providing knowledge of vital threats to the users and enterprises. Furthermore, in this paper, various techniques as well as methods for security measurements, analysis and prioritization within the peak of mobile platforms will be presented. Additionally, increases understanding and awareness of security on mobile application platforms to avoid detection, forensics and countermeasures used by the operating systems. Finally, this study also discusses security extensions for popular mobile platforms and analysis for a survey within a recent research in the area of mobile platform security
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

Danger is My Middle Name: Experimenting with SSL Vulnerabilities in Android Apps
This paper presents a measurement study of information leakage and SSL
vulnerabilities in popular Android apps. We perform static and dynamic analysis
on 100 apps, downloaded at least 10M times, that request full network access.
Our experiments show that, although prior work has drawn a lot of attention to
SSL implementations on mobile platforms, several popular apps (32/100) accept
all certificates and all hostnames, and four actually transmit sensitive data
unencrypted. We set up an experimental testbed simulating man-in-the-middle
attacks and find that many apps (up to 91% when the adversary has a certificate
installed on the victim's device) are vulnerable, allowing the attacker to
access sensitive information, including credentials, files, personal details,
and credit card numbers. Finally, we provide a few recommendations to app
developers and highlight several open research problems.Comment: A preliminary version of this paper appears in the Proceedings of ACM
