Trainer Name: Ankur Bhargava
Title: Securing Android Applications
Duration: 3 Days
Dates: Sept. 6, 2022 To Sept. 8, 2022


This course starts by talking about the basics of android and then goes into attacking android applications focusing on vulnerabilities and how to secure against them. Another part of the course focuses on the application development process and attempts to establish various flows where security is not an afterthought but rather a built-in part of the process. To be clear this is not another “let’s fill CI/CD with tools” training. We will be focusing on understanding what threat landscape is exposed to an application, threat-model different application scenarios and then we will work on various tools, techniques, and procedures that people need to follow to achieve a solid security posture on the application.

Major areas covered are

  • Basics of android.
  • Android-specific vulnerabilities and how to secure against them.
  • Identifying weaknesses
  • Adding Security to CI / CD Pipeline for the application
  • Security beyond just tools

Training level: Basic; Intermediate

Securing Android Application

  • Understanding the development process and how to do Secure SDLC
  • OWASP MASVS and its usage along with additional observations
  • Establish defense methodology and strategy
  • Identify various issues in code via static code analysis (semgrep and other tools)
  • Introduction to CI / CD Pipeline for Android applications
  • Identifying various tools to be placed in the CI / CD pipeline
    • SAST
    • DAST
    • Third-party library tracking

CTF: Multiple challenges will be made available to students during the whole course Best practices while coding android applications.


Laptop with:

  • 80+ GB free hard disk space
  • 8+ GB RAM
  • VirtualBox / VMWare installed on the machine
  • Administrative access to the system and BIOS
  • External USB access allowed

Setup instructions will be sent over as part of pre-course communication. On-site help can be provided with regards to VM Setup but would absolutely need administrative access on laptop OS as well as BIOS.


The course assumes basic familiarity with command-line and Linux. A user-level understanding of Android phones is good to have knowledge.


  • Android Developers
  • Android application architects
  • Product security engineers


  • Very Detailed step-by-step instruction manual for all challenges covered during the class.
  • A Slide deck containing the slides covered during the class
  • A set of Virtual Machine with all required tools pre-configured


  • How to attack android applications, including vulnerabilities from owasp and beyond.
  • Securing android application, what not to do.
  • How to set baseline security in android application
  • How to establish defenses for the android application


Becoming a zero to hero in 3 days of training. This training provides you with the path and guidance needed to walk the path. Students will have to walk the path on their own. The trainer will guide but the efforts will be needed from the students.
