Android Security: Attacks and Defenses is for anyone interested in learning about the strengths and weaknesses of the Android platform from a security perspective. Starting with an introduction to Android OS architecture and application programming, it will help readers get up to speed on the basics of the Android platform and its security issues.
Explaining the Android security model and architecture, the book describes Android permissions, including Manifest permissions, to help readers analyze applications and understand permission requirements. It also rates the Android permissions based on security implications and covers JEB Decompiler.
The authors describe how to write Android bots in JAVA and how to use reversing tools to decompile any Android application. They also cover the Android file system, including import directories and files, so readers can perform basic forensic analysis on file system and SD cards. The book includes access to a wealth of resources on its website: www.androidinsecurity.com. It explains how to crack SecureApp.apk discussed in the text and also makes the application available on its site.
The book includes coverage of advanced topics such as reverse engineering and forensics, mobile device pen-testing methodology, malware analysis, secure coding, and hardening guidelines for Android. It also explains how to analyze security implications for Android mobile devices/applications and incorporate them into enterprise SDLC processes.
The book’s site includes a resource section where readers can access downloads for applications, tools created by users, and sample applications created by the authors under the Resource section. Readers can easily download the files and use them in conjunction with the text, wherever needed. Visit www.androidinsecurity.com for more information.

By the HelloWorld Application 46 Android Security: Attacks and Defenses Android SDK. We concluded the chapter by examining the structure of a typical Android project and application. The reader should now be familiar with different terms used across the stack. Chapter 3 Android Application Architecture In this chapter, we introduce the reader to Android Application Architecture. We present various components that make up an Android application, and we demonstrate how these components work.
Vulnerability described here was not theoretical. There have been cases where a similar issue could have resulted in compromised user data. 7.4 Real World Example 1—Google Wallet Vulnerability Google Wallet is mobile payment software developed by Google. It allows users to store (securely) credit card numbers, gift cards, and so forth, on their cell phones. It uses Near Field Communication (NFC) to make secure payments on PayPass-enabled terminals at checkout counters (e.g., MasterCard’s.
Depending on the type of application, it might be possible to perform sensitive operations and data processing on the server side. For example, for an application that pulls data from the server to load locally (e.g., twitter), much of the application logic is performed on the server end. Once the application authenticates successfully and the validity of the user is verified, the application can rely on the server side for much of the processing. Thus, even if compiled binary is reverse.
Space-time or timememory trade off (i.e., increasing memory reduces computation time). In addition, we recommend using iterative hashing for sensitive data. This means simply taking the hash of data and hashing it again and so on. If this is done a sufficient number of times, the resultant hash can be fairly strong against brute force attacks in case an attacker can guess or capture the hash value. 7.6.4 Choose the Right Location for Sensitive Information The location of sensitive information.
Application. The Seesmic application has three folders: databases, libs, and shared_prefs. Accessing the /data/data directory on the device would not be possible, as permissions are restricted to the system owner (as opposed to the shell user). One has to either root the phone or image it to be able to obtain access to the contents of this directory.
