Cross-Platform Analysis of Indirect File Leaks in Android and Ios Applications
Cross-Platform Analysis of Indirect File Leaks in Android and iOS Applications Daoyuan Wu and Rocky K. C. Chang Department of Computing, The Hong Kong Polytechnic University fcsdwu, [email protected] This paper was published in IEEE Mobile Security Technologies 2015 [47] with the original title of “Indirect File Leaks in Mobile Applications”. Victim App Abstract—Today, much of our sensitive information is stored inside mobile applications (apps), such as the browsing histories and chatting logs. To safeguard these privacy files, modern mobile Other systems, notably Android and iOS, use sandboxes to isolate apps’ components file zones from one another. However, we show in this paper that these private files can still be leaked by indirectly exploiting components that are trusted by the victim apps. In particular, Adversary Deputy Trusted we devise new indirect file leak (IFL) attacks that exploit browser (a) (d) parties interfaces, command interpreters, and embedded app servers to leak data from very popular apps, such as Evernote and QQ. Unlike the previous attacks, we demonstrate that these IFLs can Private files affect both Android and iOS. Moreover, our IFL methods allow (s) an adversary to launch the attacks remotely, without implanting malicious apps in victim’s smartphones. We finally compare the impacts of four different types of IFL attacks on Android and Fig. 1. A high-level IFL model. iOS, and propose several mitigation methods. four IFL attacks affect both Android and iOS. We summarize these attacks below. I. INTRODUCTION • sopIFL attacks bypass the same-origin policy (SOP), Mobile applications (apps) are gaining significant popularity which is enforced to protect resources originating from in today’s mobile cloud computing era [3], [4]. -

Download Android Os for Phone Open Source Mobile OS Alternatives to Android
download android os for phone Open Source Mobile OS Alternatives To Android. It’s no exaggeration to say that open source operating systems rule the world of mobile devices. Android is still an open-source project, after all. But, due to the bundle of proprietary software that comes along with Android on consumer devices, many people don’t consider it an open source operating system. So, what are the alternatives to Android? iOS? Maybe, but I am primarily interested in open-source alternatives to Android. I am going to list not one, not two, but several alternatives, Linux-based mobile OSes . Top Open Source alternatives to Android (and iOS) Let’s see what open source mobile operating systems are available. Just to mention, the list is not in any hierarchical or chronological order . 1. Plasma Mobile. A few years back, KDE announced its open source mobile OS, Plasma Mobile. Plasma Mobile is the mobile version of the desktop Plasma user interface, and aims to provide convergence for KDE users. It is being actively developed, and you can even find PinePhone running on Manjaro ARM while using KDE Plasma Mobile UI if you want to get your hands on a smartphone. 2. postmarketOS. PostmarketOS (pmOS for short) is a touch-optimized, pre-configured Alpine Linux with its own packages, which can be installed on smartphones. The idea is to enable a 10-year life cycle for smartphones. You probably already know that, after a few years, Android and iOS stop providing updates for older smartphones. At the same time, you can run Linux on older computers easily. -
SMM Rootkits
SMM Rootkits: A New Breed of OS Independent Malware Shawn Embleton Sherri Sparks Cliff Zou University of Central Florida University of Central Florida University of Central Florida [email protected] [email protected] [email protected] ABSTRACT 1. INTRODUCTION The emergence of hardware virtualization technology has led to A rootkit consists of a set of programs that work to subvert the development of OS independent malware such as the Virtual control of an Operating System from its legitimate users [16]. If Machine based rootkits (VMBRs). In this paper, we draw one were asked to classify viruses and worms by a single defining attention to a different but related threat that exists on many characteristic, the first word to come to mind would probably be commodity systems in operation today: The System Management replication. In contrast, the single defining characteristic of a Mode based rootkit (SMBR). System Management Mode (SMM) rootkit is stealth. Viruses reproduce, but rootkits hide. They hide is a relatively obscure mode on Intel processors used for low-level by compromising the communication conduit between an hardware control. It has its own private memory space and Operating System and its users. Secondary to hiding themselves, execution environment which is generally invisible to code rootkits are generally capable of gathering and manipulating running outside (e.g., the Operating System). Furthermore, SMM information on the target machine. They may, for example, log a code is completely non-preemptible, lacks any concept of victim user’s keystrokes to obtain passwords or manipulate the privilege level, and is immune to memory protection mechanisms. -

Nujj University of California, Berkeley School of Information Karen Hsu Kesava Mallela Alana Pechon Nujj • Table of Contents Abstract 1 Introduction 2 Problem Statement 2 Objective 2 Literature Review 3 Competitive Analysis 4 Comparison matrix 4 Competition 5 Hypothesis 6 Use Case Scenarios 7 Overall System Design 10 Server-side 12 Design 12 Implementation 12 Twitter and Nujj 14 Client-side 15 Design 17 Implementation 17 Future Work 18 Extended Functionality in Future Implementations 18 Acknowledgements 19 Abstract Nujj is a location based service for mobile device users that enables users to tie electronic notes to physical locations. It is intended as an initial exploration into some of the many scenarios made possible by the rapidly increasing ubiquity of location-aware mobile devices. It should be noted that this does not limit the user to a device with a GPS embedded; location data can now also be gleaned through methods such as cell tower triangulation and WiFi IP address lookup. Within this report, both social and technical considerations associated with exposing a user’s location are discussed. The system envisioned addresses privacy concerns, as well as attempts to overcome the poor rate of adoption of current location based services already competing in the marketplace. Although several possible use cases are offered, it is the authors’ firm belief that a well-designed location- based service should not attempt to anticipate all, or even most, of the potential ways that users will find to take advantage of it. Rather, the service should be focused on building a system that is sufficiently robust yet flexible to allow users to pursue their own ideas.
