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.

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. -
A Comparative Analysis of Mobile Operating Systems Rina
International Journal of Computer Sciences and Engineering Open Access Research Paper Vol.-6, Issue-12, Dec 2018 E-ISSN: 2347-2693 A Comparative Analysis of mobile Operating Systems Rina Dept of IT, GGDSD College, Chandigarh ,India *Corresponding Author: [email protected] Available online at: www.ijcseonline.org Accepted: 09/Dec/2018, Published: 31/Dec/2018 Abstract: The paper is based on the review of several research studies carried out on different mobile operating systems. A mobile operating system (or mobile OS) is an operating system for phones, tablets, smart watches, or other mobile devices which acts as an interface between users and mobiles. The use of mobile devices in our life is ever increasing. Nowadays everyone is using mobile phones from a lay man to businessmen to fulfill their basic requirements of life. We cannot even imagine our life without mobile phones. Therefore, it becomes very difficult for the mobile industries to provide best features and easy to use interface to its customer. Due to rapid advancement of the technology, the mobile industry is also continuously growing. The paper attempts to give a comparative study of operating systems used in mobile phones on the basis of their features, user interface and many more factors. Keywords: Mobile Operating system, iOS, Android, Smartphone, Windows. I. INTRUDUCTION concludes research work with future use of mobile technology. Mobile operating system is the interface between user and mobile phones to communicate and it provides many more II. HISTORY features which is essential to run mobile devices. It manages all the resources to be used in an efficient way and provides The term smart phone was first described by the company a user friendly interface to the users. -

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. -
The Myth of the Superuser: Fear, Risk, and Harm Online
The Myth of the Superuser: Fear, Risk, and Harm Online ∗ Paul Ohm Fear of the powerful computer user, the “Superuser,” dominates debates about online conflict. He is a mythic figure: difficult to find, immune to technological constraints, and aware of legal loopholes. Policymakers, fearful of his power, too often overreact by passing overbroad, ambiguous laws intended to ensnare the Superuser but which are instead used against inculpable, ordinary users. This response is unwarranted because the Superuser is often a marginal figure whose power has been greatly exaggerated. The exaggerated focus on the Superuser reveals a pathological characteristic of the study of power, crime, and security online, which springs from a widely held fear of the Internet. Building on the social science fear literature, this Article challenges the conventional wisdom and ∗ Associate Professor of Law and Telecommunications, University of Colorado Law School.

We Hack Wii / USB Loader
Don't upgrade to Wii Firmware 4.2! Instead of updating your Wii firmware, you can just use DOP-Mii to update specific channels such as the Nintendo Channel or Wii Shop Channel without updating the Wii System Menu. This will allow you to shop with the latest Wii Shop Channel without updating the Wii System Menu. However, the guide below DOES work if you are on 4.2 and want to hack your Wii. Don't use IOS60-Patcher for launching games from SD! Instead use DOP-Mii to re-install IOS60 (if you are on Wii Firmware 4.0 or 4.1) or IOS70 (if you are on Wii Firmware 4.2) with the signature hash check (trucha bug). Also, if you are using Preloader and you "dop" IOS60 or IOS70, remember to reinstall Preloader after "doping"; otherwise, you won't be able to load the System Menu. Instead, boot HBC through Preloader to reinstall it. What is USB Loader? USB Loader is an application for the Nintendo Wii which allows you to to install and load your backup ISO game files to/from a USB storage device. It also allows you to create such backups straight from the original DVD, or you can put ISO files which you have backed up to your computer onto your USB drive and load them from there. This guide will prepare your Wii to use USB Loader GX , which will launch both the USB drive and burned DVD-R discs. What if I just want homebrew? If you don't want to launch backup games and just want to enjoy the world of homebrew, homemade games and applications for the Wii, then you only need to follow steps 2 through 4; it couldn't be simpler.
