CHAPTER 11Attacking Windows Phone Applications

This chapter follows the previous chapter’s introduction to Windows Phone applications by exploring the various ways in which apps can be vulnerable, and how an attacker can exploit identified weaknesses.

Akin to applications that run on popular desktop and mobile platforms, Windows Phone 8.x apps may also be vulnerable. This chapter focuses on testing for, finding, and exploiting vulnerabilities around issues such as transport security weaknesses, injection vectors, Interprocess Communications (IPC) mechanisms, and native code, among others. Many of the vulnerability classes that we discuss and explore are common to software that runs on other mobile operating systems (OSes), as well as to vulnerability classes encountered in application security generally.

This chapter also covers enumeration and identification of data entry points into applications, because they are critical to understanding an app’s threat landscape and pinpointing areas of an app that are potentially vulnerable to security weaknesses.

Analyzing for Data Entry Points

Before moving on to testing for, identifying, and exploiting security vulnerabilities in Windows Phone (WP) applications, we explore a very important initial step common to all application security reviews: locating and analyzing data entry points into the app. Doing this allows a would-be attacker insight into the attack surface of the app in question.

The phrase data entry point, or simply ...
