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]. -
1 Questions for the Record from the Honorable David N. Cicilline, Chairman, Subcommittee on Antitrust, Commercial and Administra
Questions for the Record from the Honorable David N. Cicilline, Chairman, Subcommittee on Antitrust, Commercial and Administrative Law of the Committee on the Judiciary Questions for Mr. Kyle Andeer, Vice President, Corporate Law, Apple, Inc. 1. Does Apple permit iPhone users to uninstall Safari? If yes, please describe the steps a user would need to take in order to do so. If no, please explain why not. Users cannot uninstall Safari, which is an essential part of iPhone functionality; however, users have many alternative third-party browsers they can download from the App Store. Users expect that their Apple devices will provide a great experience out of the box, so our products include certain functionality like a browser, email, phone and a music player as a baseline. Most pre-installed apps can be deleted by the user. A small number, including Safari, are “operating system apps”—integrated into the core operating system—that are part of the combined experience of iOS and iPhone. Removing or replacing any of these operating system apps would destroy or severely degrade the functionality of the device. The App Store provides Apple’s users with access to third party apps, including web browsers. Browsers such as Chrome, Firefox, Microsoft Edge and others are available for users to download. 2. Does Apple permit iPhone users to set a browser other than Safari as the default browser? If yes, please describe the steps a user would need to take in order to do so. If no, please explain why not. iPhone users cannot set another browser as the default browser. -

XCSSET Update: Abuse of Browser Debug Modes, Findings from the C2 Server, and an Inactive Ransomware Module Appendix
XCSSET Update: Abuse of Browser Debug Modes, Findings from the C2 Server, and an Inactive Ransomware Module Appendix Introduction In our first blog post and technical brief for XCSSET, we discussed the depths of its dangers for Xcode developers and the way it cleverly took advantage of two macOS vulnerabilities to maximize what it can take from an infected machine. This update covers the third exploit found that takes advantage of other popular browsers on macOS to implant UXSS injection. It also details what we’ve discovered from investigating the command-and-control server’s source directory — notably, a ransomware feature that has yet to be deployed. Recap: Malware Capability List Aside from its initial entry behavior (which has been discussed previously), here is a summarized list of capabilities based on the source files found in the server: • Repackages payload modules to masquerade as well-known mac apps • Infects local Xcode and CocoaPods projects and injects malware to execute when infected project builds • Uses two zero-day exploits and trojanizes the Safari app to exfiltrate data • Uses a Data Vault zero-day vulnerability to dump and steal Safari cookie data • Abuses the Safari development version (SafariWebkitForDevelopment) to inject UXSS backdoor JS payload • Injects malicious JS payload code to popular browsers via UXSS • Exploits the browser debugging mode for affected Chrome-based and similar browsers • Collects QQ, WeChat, Telegram, and Skype user data in the infected machine (also forces the user to allow Skype and -
Adware-Searchsuite
McAfee Labs Threat Advisory Adware-SearchSuite June 22, 2018 McAfee Labs periodically publishes Threat Advisories to provide customers with a detailed analysis of prevalent malware. This Threat Advisory contains behavioral information, characteristics and symptoms that may be used to mitigate or discover this threat, and suggestions for mitigation in addition to the coverage provided by the DATs. To receive a notification when a Threat Advisory is published by McAfee Labs, select to receive “Malware and Threat Reports” at the following URL: https://www.mcafee.com/enterprise/en-us/sns/preferences/sns-form.html Summary Detailed information about the threat, its propagation, characteristics and mitigation are in the following sections: Infection and Propagation Vectors Mitigation Characteristics and Symptoms Restart Mechanism McAfee Foundstone Services The Threat Intelligence Library contains the date that the above signatures were most recently updated. Please review the above mentioned Threat Library for the most up to date coverage information. Infection and Propagation Vectors Adware-SearchSuite is a "potentially unwanted program" (PUP). PUPs are any piece of software that a reasonably security- or privacy-minded computer user may want to be informed of and, in some cases, remove. PUPs are often made by a legitimate corporate entity for some beneficial purpose, but they alter the security state of the computer on which they are installed, or the privacy posture of the user of the system, such that most users will want to be aware of them. Mitigation Mitigating the threat at multiple levels like file, registry and URL could be achieved at various layers of McAfee products. Browse the product guidelines available here (click Knowledge Center, and select Product Documentation from the Support Content list) to mitigate the threats based on the behavior described in the Characteristics and symptoms section. -
