As mobile devices have become increasingly prevalent, the security of Android applications has become a critical concern.
Pentesting is an essential process for identifying and mitigating potential vulnerabilities in these applications, but Android app hacking is a specialized area that is less well-documented than other pentesting techniques.
In this session, the focus will be on how to pentest Android apps and their APIs.
The presentation will address key questions such as what Android pentesting is, how to set up an Android App pentest lab, and how to pentest an Android App and its APIs from start to finish.
Participants will leave the session with tips and resources for learning, practicing, and setting up a complete set of tools for Android application pentesting, including detailed examples on a purposefully vulnerable application.
The goal is to equip attendees with the knowledge and skills necessary to conduct thorough and effective pentests of Android applications.
