Mobile Application Exploitation (iOS and Android)

A completely hands-on training on exploiting mobile applications for the iOS and Android platform. The training is based on exploiting Damn Vulnerable iOS app and other vulnerable apps which are written by the trainer in order to make you understand the different kinds of vulnerabilities in mobile applications. You can test your skills in the CTF at the end !

Course Description

This course will also discuss how a developer can secure their applications using secure coding and obfuscation techniques. After the workshop, the students will be able to successfully penetration test and secure mobile applications. All the students will get a PDF presentation with all the slides, vulnerable apps used for training, sample source code and all the necessary tools used to pentest mobile applications.

The training will also include a CTF challenge in the end where the attendees will use their skills learnt in the training to solve the CTF challenges.
