👉 Overview
👀 What ?
iOS hooking with Objection is the process of intercepting and altering the flow of data and instructions within an application on an iOS device using the Objection runtime mobile exploration toolkit.
🧐 Why ?
This technique is important in cybersecurity as it allows security researchers and penetration testers to understand how an application works, identify potential vulnerabilities, and test the effectiveness of security measures. It is especially useful in assessing the security of iOS applications, as these are often used to handle sensitive data.
⛏️ How ?
To use Objection for iOS hooking, you first need to install it on your machine. Then, you can connect your iOS device to your machine, launch the target application, and use Objection commands to interact with the application's runtime. This allows you to manipulate the application's data and functionality, revealing how it works and where it may be vulnerable.
⏳ When ?
iOS hooking with Objection has been in use since the toolkit was first released in 2017. It is particularly relevant today, as mobile application security has become increasingly important in the face of growing cyber threats.
⚙️ Technical Explanations
Objection uses Frida, a dynamic code instrumentation toolkit, to attach to the running process of an iOS application. It then injects JavaScript code that can intercept and modify function calls and data within the application. This allows for a wide range of exploration and manipulation capabilities, from viewing and altering an application's files and databases, to invoking hidden or non-public methods and altering runtime variables.
