The series will be assuming that the user is using Electra jailbreak. ‘Objection’, created by Sensepost, is another useful tool built on top of Frida that makes analysis much faster and easier. ‘Frida’ is a dynamic instrumentation tool that is primarily useful for runtime manipulation and dynamic analysis.

In the upcoming blog post, we will look more into Frida Scripting and how you could leverage Frida’s API and additional tools to perform iOS and Android application security assessment.This post is part 3 of a series giving an overview of the most useful iOS app pentesting tools. Jailbreak Detection Bypass – Device is Not Jailbroken Conclusion If you look in your iOS application now, it would say that the Device is not Jailbroken (as shown below). Patching function by modifying the return value in an iOS app – Jailbreak Detection bypass

Once we run this, we see that the return value has been modified as shown below. Let’s get started by identifying all the classes in the application. IOS application security process Finding Classes for Jailbreak Detection with Frida in DVIA Here, we will be looking for anything related to Jailbreak, so that we are able to perform Jailbreak Bypass with the help of Frida.

Let’s go ahead and write a basic Frida script to dump all the various classes and methods present in our target application. The goal for this exercise is to identify which ViewController and function are responsible for validating whether our device is jailbroken or not – in the Jailbreak Detection exercise of DVIA. We can either work here in the Frida’s shell and interact with our process, or we can write our own JavaScript to obtain analyze the data that we want. To attach to any process, we could do a frida –U process-name and we would now be in the frida console where we can access all the different properties, memory content and functions of our target process. Let’s start by seeing a list of all the running processes on our target device:Īs you can see from the screenshot above, we now have a list of all the running processes on our iOS device. We are going to be analyzing the Jailbreak Detection exercise from DVIA, which currently shows that the device is Jailbroken. The credits for most of the scripts below go to Interference Security Github’s repo available here. The target application in our case is the Damn Vulnerable iOS Application (DVIA) by Prateek Gianchandani, available from here. Now that we have Frida all set up, we are ready to start using Frida and start our iOS application security assessment and exploitation journey!

To install Frida’s Python bindings on your system, launch up your terminal and type in pip install frida to install Frida’s bindings.

Open up the Source or search for Frida, and click on Modify, then Install.

To install Frida server on your iOS device, follow the below steps. You need to perform setup both on the iOS device as well as your host machine. Setting up Frida to perform iOS application security is fairly straightforward. In order to run Frida to debug applications on non-jailbroken devices, you can use tools such as Swizzler2 which modifies the application to add the FridaGadget dylib in the app. One of the other things which make Frida so useful is its ability to work on non-jailbroken devices. There have been several tools which are built on Frida including Needle and AppMon. The API of Frida is what makes it so powerful and a first choice for building your own security or analysis tools. The reason why I mentioned “and so on” is because Frida could be used for a number of different purposes.

Dumping class and method information from an iOS app.

Performing debugging of your own applications.

Analysing custom protocols in place and sniffing/decrypting the traffic on the fly.

Hooking into a specific function and changing the return value.

Some of the use cases of Frida (depending on for which purpose you are using it) are –

Ravnås ( and also has a pretty active IRC channel where you can jump in to discuss ideas, questions and new features with other like minded people who have worked on Frida.

Runtime manipulation of iOS apps using Fridaįrida is a dynamic code instrumentation toolkit allowing you to hook into applications, inject your own JavaScript while getting complete access to the memory and functions.Connecting to an iOS process using Frida.Here’s what we are going to cover in this blog post: This is also something we cover in-depth in our Advanced Android and iOS Exploitation training for which you can register here – Training LinkĮven if you have never used Frida, this post will serve as a guide for you to get started into the world of Frida for Mobile application security analysis and exploitation. In this blog post, we will have a look at Frida, which is one of the really interesting tools for mobile application security analysis.
