Rooting & Flashing Android Phones By Louis Le What does rooting mean? ● Android is a version of Linux ● Makes you superuser of phone What does flashing mean? ● Installing a ROM onto phone ● ROM: file with executable of an Android OS and related apps Cons of Rooting ● Voids phone manufacturer’s warranty ● Possibility of “bricking” phone ● Makes phone more vulnerable to viruses ● Can be illegal depending on where in the US you live according to the Digital Millennium Copyright Act (DMCA) Pros of Rooting ● Remove bloatware ● Flash custom ROMs ● Apps ● Overclocking/saving battery ● Custom Kernels ● Mobile tethering for free Steps for Rooting 1) Unlocking bootloader - Opens the door to the internal memory of the device to be written on to. a) This allows you to flash images onto the main partitions of the phone. 2) Installing custom recovery - overwrite stock Android recovery a) Allows for creating/restoring backups b) Flash ROMs 3) Gaining Root Access Prerequisite Part ● Download: ○ ADB (Android Debug Bridge): lets you communicate with android device ○ Fastboot - tool/protocol used to modify file system images ● Make sure phone is charged and PC is plugged in ● Backup! ● USB Debugging - establishes connection between Android phone and Android SDK ● OEM (Original Equipment Manufacturer) Unlocking - gives option to unlock bootloader ● Download TWRP (Team Win Recovery Project) and Magisk Fastboot Part I. Reboot phone into fastboot mode (2 methods) II. “fastboot devices” III. “fastboot oem unlock” IV. Place Magisk on Device Internal memory V. “fastboot flash recovery (file name).img” VI. Reboot phone in recovery mode (2 methods) A. “fastboot boot recovery.img” TWRP Part I. Install Magisk to root phone II. Reboot (but wait!) Flashing Custom ROM 1. Wipe -> Format Data 2. Advance Wipe -> Cache, System 3. “adb push filename.zip /sdcard/” 4. Install .zip package 5. Reboot -> System ● Guide I used: https://forums.oneplus.com/threads/oneplus-5t-unlock-bootloader-flash-twrp-r oot-nandroid-efs.685403/ ● Custom ROM I installed: https://lineageos.org/ .

On Root Detection Strategies for Android Devices

Its success is driven by its availability channels used. to a variety of smartphone hardware vendors on the one hand, This can directly contradict with users enjoying the cus- and the customization possibilities given to its users on the other hand. While other big smartphone operating systems restrict user tomizability of their devices, as one popular method to enable configuration to a given set of functionality, Android users can broad control over ones’ device is the act of gaining elevated leverage the whole potential of their devices. This high degree privileges through a process called rooting. of customization enabled by a process called rooting, where the As our main contribution we propose a method for remote users escalate their privileges to those of the operating system, rooting detection in wireless tethering networks provided by introduces security, data integrity and privacy concerns. Several rooting detection mechanisms for Android devices already exist, an Android device. Such networks define a special case of aimed at different levels of detection. This paper introduces wireless networks, as all communication is routed over the further strategies derived from the Linux ecosystem and outlines device offering the hotspot, and can thus be manipulated by their usage on the Android platform. In addition, we present said device. One example for extensive tethering hotspot usage a novel remote rooting detection approach aimed at trust and and a matching use case for this remote rooting detection is integrity checks between devices in wireless networks.

Android Malware Detection Via (Somewhat) Robust Irreversible Feature Transformations
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Citation information: DOI 10.1109/TIFS.2020.2975932, IEEE Transactions on Information Forensics and Security IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY 1 Android Malware Detection via (Somewhat) Robust Irreversible Feature Transformations Qian Han1, V.S. Subrahmanian1 and Yanhai Xiong1 1Department of Computer Science and the Institute for Security Technology and Society Dartmouth College, Hanover, NH 03755, USA As the most widely used OS on earth, Android is heavily targeted by malicious hackers. Though much work has been done on detecting Android malware, hackers are becoming increasingly adept at evading ML classifiers. We develop FARM, a Feature transformation based AndRoid Malware detector. FARM takes well-known features for Android malware detection and introduces three new types of feature transformations that transform these features irreversibly into a new feature domain. We first test FARM on 6 Android classification problems separating goodware and “other malware” from 3 classes of malware: rooting malware, spyware, and banking trojans. We show that FARM beats standard baselines when no attacks occur. Though we cannot guess all possible attacks that an adversary might use, we propose three realistic attacks on FARM and show that FARM is very robust to these attacks in all classification problems. Additionally, FARM has automatically identified two malware samples which were not previously classified as rooting malware by any of the 61 anti-viruses on VirusTotal. These samples were reported to Google’s Android Security Team who subsequently confirmed our findings.

You may not use the material for commercial purposes. 1 Overview Android devices do not allow their owners to have the root privilege on the device. This is ﬁne for normal customers, but for users who want to make deep customizations on their devices, this is too restrictive. There are ways to overcome these restrictions, most of which require the root privilege on the device. The process of gaining the root device on Android devices is called rooting. Being able to root Android devices is a very useful skill for security experts. The objective of this lab is two-fold. First, through this lab, students will get familiar with the process of device rooting and understand why certain steps are needed. Many people can root Android devices, but not many people fully understand why things have to be done in a particular way. Second, the entire rooting mechanism involves many pieces of knowledge about the Android system and operating system in general, so it serves as a great vehicle for students to gain such in-depth system knowledge.
