Static analysis of android apps interaction with automotive CAN

Modern car infotainment systems allow users to connect an Android device to the vehicle. The device then interacts with the hardware of the car, hence providing new interaction mechanisms to the driver. However, this can be misused and become a major security breach into the car, with subsequent security concerns: the Android device can both read sensitive data (speed, model, airbag status) and send dangerous commands (brake, lock, airbag explosion). Moreover, this scenario is unsettling since Android devices connect to the cloud, opening the door to remote attacks by malicious users or the cyberspace. The OpenXC platform is an open-source API that allows Android apps to interact with the car’s hardware. This article studies this library and shows how it can be used to create injection attacks. Moreover, it introduces a novel static analysis that identifies such attacks before they actually occur. It has been implemented in the Julia static analyzer and finds injection vulnerabilities in actual apps from the Google Play marketplace

On the road with third-party apps: Security analysis of an in-vehicle app platform

Digitalization has revolutionized the automotive industry. Modern cars are equipped with powerful Internetconnected infotainment systems, comparable to tablets and smartphones. Recently, several car manufacturers have announced the upcoming possibility to install third-party apps onto these infotainment systems. The prospect of running third-party code on a device that is integrated into a safety critical in-vehicle system raises serious concerns for safety, security, and user privacy. This paper investigates these concerns of in-vehicle apps. We focus on apps for the Android Automotive operating system which several car manufacturers have opted to use. While the architecture inherits much from regular Android, we scrutinize the adequateness of its security mechanisms with respect to the in-vehicle setting, particularly affecting road safety and user privacy. We investigate the attack surface and vulnerabilities for third-party in-vehicle apps. We analyze and suggest enhancements to such traditional Android mechanisms as app permissions and API control. Further, we investigate operating system support and how static and dynamic analysis can aid automatic vetting of in-vehicle apps. We develop AutoTame, a tool for vehicle-specific code analysis. We report on a case study of the countermeasures with a Spotify app using emulators and physical test beds from Volvo Cars

Security Analysis of Web and Embedded Applications

As we put more trust in the computer systems we use the need for securityis increasing. And while security features like HTTPS are becomingcommonplace on the web, securing applications remains dicult. This thesisfocuses on analyzing dierent computer ecosystems to detect vulnerabilitiesand develop countermeasures. This includesweb browsers,web applications,and cyber-physical systems such as Android Automotive.For web browsers, we analyze how new security features might solve aproblem but introduce new ones. We show this by performing a systematicanalysis of the new Content Security Policy (CSP) directive navigate-to.In our research, we nd that it does introduce new vulnerabilities, to whichwe recommend countermeasures. We also create AutoNav, a tool capable ofautomatically suggesting navigation policies for this directive.To improve the security of web applications, we develop a novel blackboxmethod by combining the strengths of dierent black-box methods. Weimplement this in our scanner Black Widow, which we compare with otherleading web application scanners. Black Widow both improves the coverageof the web application and nds more vulnerabilities, including ones inPrestashop, WordPress, and HotCRP.For embedded systems,We analyze the new attack vectors introduced bycombining a phone OS with vehicle APIs and nd new attacks pertaining tosafety, privacy, and availability. Furthermore, we create AutoTame, which isdesigned to analyze third-party apps for vehicles for the vulnerabilities wefound

Securing the Next Generation Web

With the ever-increasing digitalization of society, the need for secure systems is growing. While some security features, like HTTPS, are popular, securing web applications, and the clients we use to interact with them remains difficult.To secure web applications we focus on both the client-side and server-side. For the client-side, mainly web browsers, we analyze how new security features might solve a problem but introduce new ones. We show this by performing a systematic analysis of the new Content Security Policy (CSP)\ua0 directive navigate-to. In our research, we find that it does introduce new vulnerabilities, to which we recommend countermeasures. We also create AutoNav, a tool capable of automatically suggesting navigation policies for this directive. Finding server-side vulnerabilities in a black-box setting where\ua0 there is no access to the source code is challenging. To improve this, we develop novel black-box methods for automatically finding vulnerabilities. We\ua0 accomplish this by identifying key challenges in web scanning and combining the best of previous methods. Additionally, we leverage SMT solvers to\ua0 further improve the coverage and vulnerability detection rate of scanners.In addition to browsers, browser extensions also play an important role in the web ecosystem. These small programs, e.g. AdBlockers and password\ua0 managers, have powerful APIs and access to sensitive user data like browsing history. By systematically analyzing the extension ecosystem we find new\ua0 static and dynamic methods for detecting both malicious and vulnerable extensions. In addition, we develop a method for detecting malicious extensions\ua0 solely based on the meta-data of downloads over time. We analyze new attack vectors introduced by Google’s new vehicle OS, Android Automotive. This\ua0 is based on Android with the addition of vehicle APIs. Our analysis results in new attacks pertaining to safety, privacy, and availability. Furthermore, we\ua0 create AutoTame, which is designed to analyze third-party apps for vehicles for the vulnerabilities we found

Implementation of Augmented Reality in Automotive Mobile Learning Application

Nowadays, the young generation is the technology generation. Most of the students used technology devices such as smartphones as their mobile-learning tools. Students used their mobile devices to download learning applications for self-learning through devices. However, most of the existing applications do not teach full- learning and no tutorials. One of the example applications is the automotive learning application. Therefore, the AUTOGO application is introduced to help students learn and guide them about automotive subjects. AUTOGO is a mobile learning application using the Augmented Reality approach for Form 4 and 5 students from Kolej Vokasional Kluang (KVK). The methodology chosen for the development process is the Multimedia Mobile Content Development (MMCD) method. The software selected to develop the AUTOGO application are Unity3D and Visual Studio Code with C# language. The result of the beta testing show AUTOGO application is completely functioning as expected. Thus, the application of beta testing scores on the System Usability Scale (SUS) is 93% which means it falls within the acceptance range

Program Analysis of Commodity IoT Applications for Security and Privacy: Challenges and Opportunities

Recent advances in Internet of Things (IoT) have enabled myriad domains such as smart homes, personal monitoring devices, and enhanced manufacturing. IoT is now pervasive---new applications are being used in nearly every conceivable environment, which leads to the adoption of device-based interaction and automation. However, IoT has also raised issues about the security and privacy of these digitally augmented spaces. Program analysis is crucial in identifying those issues, yet the application and scope of program analysis in IoT remains largely unexplored by the technical community. In this paper, we study privacy and security issues in IoT that require program-analysis techniques with an emphasis on identified attacks against these systems and defenses implemented so far. Based on a study of five IoT programming platforms, we identify the key insights that result from research efforts in both the program analysis and security communities and relate the efficacy of program-analysis techniques to security and privacy issues. We conclude by studying recent IoT analysis systems and exploring their implementations. Through these explorations, we highlight key challenges and opportunities in calibrating for the environments in which IoT systems will be used.Comment: syntax and grammar error are fixed, and IoT platforms are updated to match with the submissio

Results show that almost 80% of the apps are potentially vulnerable, out of which 25% poses security threats related to execution of JavaScript

Federated Robust Embedded Systems: Concepts and Challenges

The development within the area of embedded systems (ESs) is moving rapidly, not least due to falling costs of computation and communication equipment. It is believed that increased communication opportunities will lead to the future ESs no longer being parts of isolated products, but rather parts of larger communities or federations of ESs, within which information is exchanged for the benefit of all participants. This vision is asserted by a number of interrelated research topics, such as the internet of things, cyber-physical systems, systems of systems, and multi-agent systems. In this work, the focus is primarily on ESs, with their specific real-time and safety requirements. While the vision of interconnected ESs is quite promising, it also brings great challenges to the development of future systems in an efficient, safe, and reliable way. In this work, a pre-study has been carried out in order to gain a better understanding about common concepts and challenges that naturally arise in federations of ESs. The work was organized around a series of workshops, with contributions from both academic participants and industrial partners with a strong experience in ES development. During the workshops, a portfolio of possible ES federation scenarios was collected, and a number of application examples were discussed more thoroughly on different abstraction levels, starting from screening the nature of interactions on the federation level and proceeding down to the implementation details within each ES. These discussions led to a better understanding of what can be expected in the future federated ESs. In this report, the discussed applications are summarized, together with their characteristics, challenges, and necessary solution elements, providing a ground for the future research within the area of communicating ESs
