Trainer Name: Sneha Rajguru
Title: Mobile Application Hacking - Master Class
Duration: 2 Days
Dates: 27th - 28th Feb 2019

Course Abstract:

Mobile Application Hacking is a hands-on class designed to teach participants with techniques and tools for Android mobile application penetration testing. The class covers a wealth of techniques to identify, analyze and exploit vulnerabilities in the mobile apps. The class also covers inbuilt security schemes in Android platforms and teaches how to bypass those security models on the Android platforms.

The class is equipped with labs that contain intentionally crafted real-world vulnerable Android apps by the author and enables participants to learn the art of finding and exploiting flaws in mobile applications. The class also has a CTF in the end which gives the participants the opportunity to test their skills which they will learn in the class.

Note: This is a major upgrade of the previous class by the author “Mobile App Attack” which was delivered around the world at conferences such as OWASP AppSec USA, DeepSec, DEFCON, NullCon and BSides LV. 

Training Outline: 

This training will mainly focus on the following :

  • Arm basics and Android native code.
  • Reverse engineer Dex code for security analysis.
  • Rooting of the device and also various techniques to detect Root.
  • Runtime analysis of the apps by active debugging.

Modifying parts of the code, where any part can be specified as some functions, classes and to perform this check or to identify the modification, we will learn how to find and calculate the checksum of the code. Our objective in this section will be to learn, Reverse Engineering an application, get its executable binaries, modify these binaries accordingly, resign the application.

Runtime modification of code. Objective is to learn how the programs/codes can be changed or modified at runtime. We will learn how to perform introspection or overriding the default behaviour of the methods during runtime and then we will learn how to identify if the methods have been changed).

Hooking an application and learn to perform program/code modification.

By the end of training, based on the course content CTF challenges written by the trainer will be launched, where the attendees will use their skills learnt in the workshop to solve the CTF challenges. The training will begin with a quick understanding on the architecture, file system, permissions and security model of the Android platform.
