Trainer Name: Abhinav Mishra
Title: Hacking iOS Applications, Like A Pro
Duration: 3 Days
Dates: 3rd - 5th March 2020


Can you guess an attack surface, which is constantly moving, connecting to several different wifi, stores user critical information and is still highly insecure? Well the answer is, Mobile applications. With almost 15% market share, iOS devices and iOS applications handle huge amount of user data. This requires these apps to be very secure and strong in terms of security. Though, that's not the case often. This comprehensive training will talk about real world iOS application security issues, and will teach the delegates, how to find and exploit those vulnerabilities.


A training designed to teach the skills required to find and exploit vulnerabilities in real world iOS applications. The training includes exploits and vulnerabilities discovered on several penetration tests or in bug bounty programs. The target mobile apps used in this training are a state of art training apps, enabling attendees to change the security controls through a hidden menu. One app to understand both sides of the coin i.e. secure & insecure implementations, in action. The training application is also available in both formats, Objective C and Swift. As all topics are followed by challenges, to be first solved by the delegate, it teaches a hands on, real world approach.
