Mobile devices are increasingly becoming a greater crutch for all generations. All the while, these users are garnering a greater desire for privacy and style. Apple presents a device that is known for its security, but lacks major user customization. On the other hand, Google has developed a device that is keen to customization with Android, but can be susceptible to security flaws. This thesis strives to discuss the security models, app store protections, and best practices of both mobile operating systems. In addition, multiple experiments were conducted to demonstrate how an Android device could be more easily compromised after altering few settings, as well as to demonstrate the privileges, both good and bad, that could be gained by jailbreaking an iOS device.

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.

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.

Seminar paper from the year 2018 in the subject Computer Science - IT-Security, grade: 1,0, Technical University of Munich, course: Seminar Mobile Application Security, language: English, abstract: Smartphones are being used as the preferred device for as many things as possible in today's world. This is why having secure phones that are resilient against attacks targeting their users’ data, becomes more and more important. This paper tries to assess what measures device vendors have taken to ensure those attacks will not be successful. Because the market is mostly divided between Google’s Android and Apple's iOS, we put our focus on those two operating systems and compare their respective security models. Additionally this comparison will be evaluating how those models have changed over time since the beginning of the smartphone era around 2010. The last part of this analysis will take a look at a different view on smartphones, the perspective of so-called "power users": Those are people that do not only use their smartphone for downloading some apps and surfing the Internet but rather want to do some lower-level customization to the operating system, by rooting their Android device or jailbreaking their iPhone. This process of gaining full privileges on the phone not only creates advantages for the user but can also have rather negative implications on the device's security. How exactly does this affect the protections implemented by the vendor?
