Droid-Sec Exploitation

Blessen Thomas


The Droid-Sec Exploitation training will enable attendees to master various android application penetration testing techniques and exploitation methods. With the rise of IoT devices, we have also included IoT smart watch wearable application penetration testing methodology and case studies.

This training focuses on practical hands-on exercises on several dedicated vulnerable apps, with the basic theory explained prior to the Do-It-Yourself mind-bending exercises - enabling the attendee to test his acquired skills during the training course.

This two-day fast-paced, brain-melting, revamped, custom-tailored, flag-ship training program will include subjects such as setting up Android pentest environments, identifying and exploiting application vulnerabilities in a variety of mobile application architectures, relevant mobile forensics, malware analysis concepts, and complementary subjects.

Key Learning Objectives:

  • Understand the Android ecosystem and application architecture
  • Identify specific threats and risks associated with the Android platform
  • Perform a hands-on penetration test and reverse engineer an Android application
  • Ability to find vulnerabilities in various real world applications for the Android platform
  • Ability to audit an android application for client engagements

What not to expect:

  • To become Android Ninja overnight.
  • Although this training will help considerably to get to the next level in Android Security, continued learning and further research in Android Security would be expected.


PREREQUISITE WARNING Each class has prerequisites for software loads and a laptop is mandatory. These individual class guides will list material the students are expected have knowledge about coming in and software tools that need to be pre-installed before attending so you get the maximum benefit from the focused intermediate or advanced level course. Please pay particular attention to the prerequisites, as the material listed there will not be reviewed in the courses, and will be necessary to get the maximum benefit out of these educational programs.
