Mobile devices such as smartphones have become an integral part of society today, shaping peoples daily life, changing the landscape of how business operate and how industries are powered today. However, the unprecedented popularity of mobile devices introduces a concerning side effect, an dramatically increasing number of security threats is posing serious risks to the security of mobile systems and the applications. Notably, one of the most successful mobile systems, Android, has exposed a plethora of vulnerabilities which are actively exploited by a large number of potentially harmful apps (malware, adwares, risk-wares, etc.), most of which are distributed in under-scrutinized third-party Android markets.Mitigating the security threats to Android is non-trivial. There has been considerable efforts in securing Android to achieve the following two complimentary goals: (1) Market-scale detection and identification of problematic apps in an efficient manner, and (2) discovery, analysis of the Android system vulnerabilities, and defense measures against the enabled attacks.In this dissertation, we propose techniques and approaches to solve specific problems in the above two aspects respectively, providing the step stones towards finally achieving these two goals. Specifically, we first present a novel software watermarking scheme, namely Droidmarking, that can efficiently and effectively impede the prevalent software plagiarism (a.k.a app repackaging) problem in the Android markets. Second, we systematically study and propose a new prevalent Android system vulnerability, which, once exploited by an attacker, can lead to serious security breaches of integrity, confidentiality and availability of the graphic user interface (GUI) on an Android device. Finally, we devise a comprehensive and practical solution to protect the GUI sub-system in Android. The defense is able to defeat all know GUI attacks while preserving the original user experience of Android. We plan to further explore Android system and app security towards a more secure ecosystem for Android.

The increasing popularity of mobile devices (e.g., Android, iOS and etc.) attracts both normal users and malware writers. In this dissertation, we conduct research on three important aspects of security problems in Android, which has a lion share (about 80%) of the current mobile market. In the application-level, we perform a comprehensive analysis on the design of top 30 antivirus detectors (AVDs) tailored for Android. One latest comparison of Android AVDs from the independent lab AV-TEST reports that the AVDs have around 95% malware detection rate. This only indicates that current AVDs on Android have good malware signature databases. When the AVDs are deployed on the fast-evolving mobile system, their effectiveness should also be measured on their runtime behavior. Our new understanding of the AVDs' design leads us to discover the hazards in adopting AVD solutions for Android. First, we measure the seriousness of the discovered hazard in the malware scan operations by developing evasion techniques, which work even under the assumption that the AVDs are equipped with "complete" virus definition files. Second, we discover that, during the engine update operations, the Android system surprisingly nullifies all types of protection of the AVDs and exposes the system to high risks. We design and develop a model checker to confirm the presence of this vulnerable program logic in all versions of Google Android source code and other vendor customized system images. We then report the findings to AVD vendors across 16 countries. In the system-level, we identify and mitigate the system vulnerabilities in Android, which cause serious denial of service (DoS). The System Server (SS) process is considered as the heart of Android, as it contains most of the Android system services in the Android framework, which provides the essential functionalities for applications (apps). However, due to the complicated design of the SS and the easily-accessible nature of its system services (e.g., through Android APIs), we conjecture that the SS may face serious DoS attacks. Through source code analysis, we have discovered a general design pattern in the concurrency control mechanism of the SS that could lead to deadly DoS attacks. As the SS plays the anchor role in Android, these DoS attacks could cause single-point-of-failure in Android. We name it Android Stroke Vulnerability (ASV), as the SS, encounters downtime when the ASV is exploited. We then design an ASV-Hunter to rank the risk level of methods in the SS to cost-efficiently discover four unknown ASVs in critical services of SS. Our further threat analysis result is daunting: by easily writing a loop to invoke Android APIs in an app, an attacker can prevent the user from patching vulnerable banking apps, reboot the device at mission critical moments (e.g., making phone calls). The ASVs can be easily leveraged to design ransomware by putting the device into repeated freezing/rebooting loops or help equip malware with anti-removal capability. Google confirmed our findings immediately after sending them a report. We also proposed defenses to secure the SS. After identifying vulnerabilities in both critical apps and system components of Android, we consider that the vulnerable and fast evolving Android system may be the next target of malware writers. Hence, we are trying to uncover the current status of Android malware development in the real world. We suspect that, during the malware development and testing phase, some Android malware writers are continuously using public scanning services (e.g., VirusTotal "VT") for testing the evasion capability of their malware samples, which we name Android malware development (AMD) cases. In this work, we designed an AMD hunting system in the context of VT to identify AMD cases and reveal new threats from Android malware development. Our system was implemented and used in a leading security company for four months. It has processed 58 million of Android sample submissions on VT, and identified 1,623 AMD cases with 13,855 samples from 83 countries. We then perform malware analysis and case studies on 890 samples selected from the identified AMD cases. Our case study reveals lots of new malware threats, including fake system app development, new phishing development, new rooting cases, new evasive techniques and etc. Besides raising the awareness of the existence of AMD cases, more importantly, our research provides a generic and scalable framework for the systematic study of AMD cases on malware submission platforms. The relevant samples that we identified will become a fresh Android malware source for the research community.

This is book offers in-depth analysis of security vulnerabilities in different mobile operating systems. It provides methodology and solutions for handling Android malware and vulnerabilities and transfers the latest knowledge in machine learning and deep learning models towards this end. Further, it presents a comprehensive analysis of software vulnerabilities based on different technical parameters such as causes, severity, techniques, and software systems’ type. Moreover, the book also presents the current state of the art in the domain of software threats and vulnerabilities. This would help analyze various threats that a system could face, and subsequently, it could guide the securityengineer to take proactive and cost-effective countermeasures. Security threats are escalating exponentially, thus posing a serious challenge to mobile platforms. Android and iOS are prominent due to their enhanced capabilities and popularity among users. Therefore, it is important to compare these two mobile platforms based on security aspects. Android proved to be more vulnerable compared to iOS. The malicious apps can cause severe repercussions such as privacy leaks, app crashes, financial losses (caused by malware triggered premium rate SMSs), arbitrary code installation, etc. Hence, Android security is a major concern amongst researchers as seen in the last few years. This book provides an exhaustive review of all the existing approaches in a structured format. The book also focuses on the detection of malicious applications that compromise users' security and privacy, the detection performance of the different program analysis approach, and the influence of different input generators during static and dynamic analysis on detection performance. This book presents a novel method using an ensemble classifier scheme for detecting malicious applications, which is less susceptible to the evolution of the Android ecosystem and malware compared to previous methods. The book also introduces an ensemble multi-class classifier scheme to classify malware into known families. Furthermore, we propose a novel framework of mapping malware to vulnerabilities exploited using Android malware’s behavior reports leveraging pre-trained language models and deep learning techniques. The mapped vulnerabilities can then be assessed on confidentiality, integrity, and availability on different Android components and sub-systems, and different layers.

Mobile technologies have become a staple in society for their accessibility and diverse range of applications that are continually growing and advancing. Users are increasingly using these devices for activities beyond simple communication including gaming and e-commerce and to access confidential information including banking accounts and medical records. While mobile devices are being so widely used and accepted in daily life, and subsequently housing more and more personal data, it is evident that the security of these devices is paramount. As mobile applications now create easy access to personal information, they can incorporate location tracking services, and data collection can happen discreetly behind the scenes. Hence, there needs to be more security and privacy measures enacted to ensure that mobile technologies can be used safely. Advancements in trust and privacy, defensive strategies, and steps for securing the device are important foci as mobile technologies are highly popular and rapidly developing. The Research Anthology on Securing Mobile Technologies and Applications discusses the strategies, methods, and technologies being employed for security amongst mobile devices and applications. This comprehensive book explores the security support that needs to be required on mobile devices to avoid application damage, hacking, security breaches and attacks, or unauthorized accesses to personal data. The chapters cover the latest technologies that are being used such as cryptography, verification systems, security policies and contracts, and general network security procedures along with a look into cybercrime and forensics. This book is essential for software engineers, app developers, computer scientists, security and IT professionals, practitioners, stakeholders, researchers, academicians, and students interested in how mobile technologies and applications are implementing security protocols and tactics amongst devices.

Snapchat. WhatsApp. Ashley Madison. Fitbit. Tinder. Periscope. How do we make sense of how apps like these-and thousands of others-have embedded themselves into our daily routines, permeating the background of ordinary life and standing at-the-ready to be used on our smartphones and tablets? When we look at any single app, it's hard to imagine how such a small piece of software could be particularly notable. But if we look at a collection of them, we see a bigger picture that reveals how the quotidian activities apps encompass are far from banal: connecting with friends (and strangers and enemies), sharing memories (and personally identifying information), making art (and trash), navigating spaces (and reshaping places in the process). While the sheer number of apps is overwhelming, as are the range of activities they address, each one offers an opportunity for us to seek out meaning in the mundane. Appified is the first scholarly volume to examine individual apps within the wider historical and cultural context of media and cultural studies scholarship, attuned to issues of politics and power, identity and the everyday.
