Outline:
This course has been prepared after years of research and experience gained through pentesting mobile applications. It is structured to follow the OWASP Mobile Top Ten and the OWASP Mobile Security Testing Guide. This is a hands-on practical course, the skills gained can be applied to mobile security assessments immediately.

Each day starts with a brief introduction to the mobile platform for that day and then continues with a look at the static analysis, moves on to dynamic checks finishing off with a nice CTF session to test the skills gained.

Day 1 includes but is not limited to a brief introduction to Android security, a series of techniques focused on static analysis, followed by dynamic analysis covering both monitoring and modifying app behavior at runtime. The day ends with beautiful CTF challenges to entertain even advanced mobile app penetration testers.

Day 2 begins with a brief iOS security crash course, static analysis techniques, followed by dynamic analysis including both monitoring and modifying app behavior at runtime. The day ends with more lovely CTF challenges.

Day 3 takes a deeper look at instrumentation on both Android and iOS, with a special focus on app behavior modification at runtime. Learn more about Frida scripts, Objection, and Xposed modules. Bypass jailbreak detection and much more. End the day by testing your skills, more CTF time!

This is a basic outline of the course; it contains various other components and details that will help the students understand and perform better. This will be a learning experience from which people relatively new to the ever-growing world of mobile security will benefit, while the advanced students will polish their skills in specific areas and perhaps complete more or the CTF challenges.
