Hacking Android, iOS and IoT apps by Example

Workshop by Abhishek J M (7aSecurity)

Abhishek J M

This course is a 100% hands-on deep dive into the OWASP Mobile Security Testing Guide (MSTG) and relevant items of the OWASP Mobile Application Security Verification Standard (MASVS), so this course covers and goes beyond the OWASP Mobile Top Ten.

Learn about Android, iOS and IoT app security by improving your mobile security testing kung-fu. Ideal for Penetration Testers, Mobile Developers and everybody interested in mobile app security.

All action, no fluff, improve your security analysis workflow and immediately apply these gained skills in your workplace, packed with exercises, extra mile challenges and CTF, self-paced and suitable for all skill levels, with continued education via unlimited email support and lifetime access to training portal with step-by-step video recordings and interesting apps to practice, including all future updates for free.

Course Objectives

This course will take any student and make sure that:

• The general level of proficiency is much higher than when they came
• The skills acquired can be immediately applied to mobile app security assessments
• Skills can be sharpened via continued education in our training portal for free
• The student is equipped to defeat common mobile app assessment challenges
• People who are new to mobile security will learn a lot in this training.
• Advanced students will come out with enhanced skills and more efficient workflows
• The skills gained are highly practical and applicable to real-world assessments

Attendees will be provided with

• ​Lifetime​ access to ​training portal​, with all course materials
• ​Unlimited access​ to ​future updates​ and step-by-step ​video recordings
• Unlimited email support​, if you need help while you practice at home later
• ​Government-mandated​ and ​police apps​ in various countries
• Many other excitingly vulnerable real-world apps
• ​IoT​ apps controlling Toys, Drones, etc.
• Digital copies of all training material
• Custom Build Lab VMs
• Purpose Build Vulnerable Test apps
• Source code for test apps

Topics Included

1. Review of Common Flaws in Source Code and at Runtime
2. Modification of App Behavior Through Code/Configuration Changes
3. Interception of Network Communication aka MitM
4. Jailbreak/Root Detection Bypasses and App Review from a Privileged Standpoint
5. Instrumentation (Review and Modification of App Behavior)
6. CTF Challenges for Attendants to Test Their Skills

Prerequisites

This course has no prerequisites as it is designed to accommodate students with different skills:

• Advanced students will enjoy comprehensive labs, extra miles and CTF challenges
• Less experienced students complete what they can during the class, and can continue at their own pace from home using the training portal.

This said, the more you learn about the following ahead of the course, the more you willget out of the course:

• Linux command line basics
• Android basics
• iOS basic

Hardware & Software required

A laptop with the following specifications:

• Ability to connect to wireless and wired networks.
• Ability to read PDF files
• Administrative rights: USB allowed, the ability to deactivate AV, firewall, install tools, etc
• Knowledge of the BIOS password, in case VT is disabled.
• Minimum 8GB of RAM (recommended: 16GB+)
• 60GB+ of free disk space (to copy a lab VM and other goodies)
• VirtualBox 6.0 or greater, including the “VirtualBox Extension Pack”
• Genymotion (can be the free version)
• A mobile phone capable of receiving text messages
• A jailbroken iPhone / iDevice with iOS >=9 (ideally: iOS 12-14) for the iOS labs
• Optional but useful: One of the following BurpSuite, ZAP or Fiddler (for MitM)
• Optional but useful: A Mac/Hackintosh with the latest XCode installed, for iOS code review & labs

Who should attend

Any mobile developer, penetration tester or person interested in mobile security will benefit from attending this training regardless of the initial skill level:

The course is for beginners, intermediate and advanced level students. While beginners are introduced to the nuances of mobile app security from scratch, intermediate and advanced level learners get to perfect both their knowledge and skills on the subject. Extra mile challenges are available in every module to help more advanced students polish their skills.

The course is crafted in a way that regardless of your skill level you will significantly improve your mobile security skills:

If you are new and cannot complete the labs during the class, that is OK, as you keep training portal access, you will learn a lot in the class but can continue from home with the training portal.

If you are more advanced in mobile security you can try to complete the labs in full and then take the CTF challenges we have for each day, you will likely also attempt to complete some exercises from home later :)

What to expect

A fully practical class that will seriously improve your mobile security knowledge and skills, regardless of the skill level you come in with.

Battle-tested tips and tricks that take your abilities to the next level and that you can apply as soon as you go back to your workplace, making security testing of mobile apps as efficient as possible.

Intensive hands-on exercises that challenge you to deep dive into the world of mobile security.

Lifetime access to training portal (including all future updates), unlimited email support, access to private groups to communicate with other students, mandated, police, IoT and otherwise interesting apps from various countries.

What not to expect

This is ​more​ than a virtual attendance course: You get the online course but also lifetime access​ to a training portal with step-by-step video recordings, slides and lab exercises, ​including all future updates for free​.

The course does ​not​ cover: Android or iOS 0-day, exploits against the platforms themselves, ARM exploit writing, writing buffer or heap overflows.

Do ​not​ expect the teachers to be talking through slides most of the time: This class is practical not theoretical, the teachers don’t bore you with slides all the time, instead you do exercises all the time and the teachers help you solve the challenges you face as you complete them.
