Jailbreak Detection Bypass: How to Disable It on Your iDevice

Now, we'll go through each tweak that can be used to minimize jailbreak detection. Some apps, however, cannot be patched and will not work when jailbroken, regardless of the content below. Other apps may need bypasses made specifically for them.

The goal of jailbreak detection is to make running the app on a non jailbroken device so that the attacker will not get more privileges, which in turn blocks some of the tools and techniques like reverse engineers etc. and it helps an application to prevent many vulnerabilities.

One-Time jailbreak detection bypass helps the pentester to permanently bypass the jailbreak detection for the respective application, Which means the pentester has to bypass the jailbreak detection only once.

For example, we can use Frida & Objection for bypassing the jailbreak detection at run-time. Once you bypass jailbreak detection with Frida & Objection, it only works till you run the Frida or objection. As you stop the Frida or objection respective applications again start detecting that the device is jailbroken.

Once a device is jailbroken, it becomes an easy target for threat actors who can flush volumes of malicious elements into the device and sniff sensitive user information. This also poses risks for the other genuine apps running on the jailbroken devices. Taking the required jailbreak detection bypass steps not only protects the app itself, but also the device and user data from being compromised at the hand of threat actors.

Note: Although iOS can be managed without the use of the Systems Manager app, additional features (e.g. GPS location, jailbreak detection) require the app. It can also be used for manual enrollments. View the following article here for more information.

Jailbreak is the method lifting user restrictions on your device set by the company. It is important to know that jailbreaking voids the warranty of your device. There are various jailbreaking methods for iOS - differing version to version. Canijailbreak is a great website for suggesting jailbreak tools based on the iOS application. It is worth mentioning, jailbreaking can be done using Windows, Mac, or Linux. Furthermore, we have different classifications of jailbreaking - which are defined below.

Objection toolkit, powered by Frida, allows you to test and analyze your mobile applications security posture without requiring a jailbreak. As it provides the easiest way to hook an application in runtime. I frequently use it to bypass SSL pinning on iOS and other issues. Basically, it lets us complete Frida operations efficiently.

However, since we are the root user, we can subvert these detection mechanisms. Largely this is done through hooking the application at run time using something like Frida, finding the functions that check the jailbreak, hooking them and then returning a false response. This can range from a simple boolean function to complex functions that require significant time to analyse and subvert.

DVIA has 5 levels of jailbreak detection. Level 2 you can do with the standard method of finding the Java class and the method, then hooking it with Frida or Objection to replace. However for the other levels this was not possible. This was due to DVIAv2 being written in Swift, and there is very little documentation on hooking Swift at runtime. I could find the methods with frida-trace, but had no meaningful way to interact with them.

I was able to learn about existing jailbreak detection methods from some online documentation and communities like r/jailbreak, but most of the useful information I learned in the course of this research came from reverse engineering popular anti-jailbreak-detection tools.

For these reasons, users of jailbroken devices frequently install anti-jailbreak-detection tools that aim to hide the tampered status of the device. These tools modify operating system functionality such that the device acts as though it were in an untampered state. They are effectively a type of intentionally installed rootkit, though generally running in userland rather than in the iOS kernel.

fileExistsAtPath is an Objective-C method commonly used to check for the existence of jailbreak artifacts. Replacing the implementation of fileExistsAtPath to always return false for a list of known jailbreak artifacts is a common strategy to defeat this jailbreak detection technique.

We mentioned that dyld exposes functionality that allows clients to inspect what libraries have been loaded into the running process. Anti-jailbreak-detection tools are loaded into processes as shared libraries, and dyld will expose this. To combat this, some anti-jailbreak-detection tools also hook exposed dyld functionality to hide their presence.

Some anti-jailbreak-detection tools are aware of this, and will actually intercept calls to dlsym and return pointers to the hooked functions. This is an interesting example of the cat-and-mouse game that has been played between app developers who wish to detect jailbroken devices and hobby developers who maintain anti-jailbreak-detection tools.

Consider that even if there was, the device has already been jailbroken, meaning arbitrary code execution is possible, and the jailbreaker would just modify whatever method of detection you would use to signal that the device has not been jailbroken.

As a result, jailbreaking your iDevice could void your warranty and violate copyright laws in your country, as well as result in fines and even imprisonment. If you jailbreak, you could face jail time.

A jailbroken iPhone is one that has been modified to allow unauthorized code execution. This means that you can install apps and tweaks that are not approved by Apple, which gives you a lot more freedom and customization options than a standard iPhone. However, jailbreaking your iPhone also voids your warranty and can make your device more vulnerable to security threats.

Many users have reported that jailbreaking your iPhone is the most secure method of unlocking the carrier. According to this method, you will have to uninstall the previous firmware on your device and then install the most recent firmware on it. As a result of the recent modification, some locks and permissions have been removed.

You can restore a jailbroken device to its original manufacturer settings by simply restoring it to its original state. Because everything from your jailbreak apps is removed by the procedure, you do not need to manually uninstall them.

To protect against the risks posed by rooted/jailbroken devices, banking apps or other apps with sensitive data need the ability to detect such conditions and to respond to them by preventing the execution or restricting the functionalities of the application. In what follows, we will see what corresponding techniques are used for jailbreak and rooting detection.

Note: Since the application has jailbreak detection mechanism in it, it crashes and closes whenever the user tries to open the application, hence disabling the user to use this application on a jailbroken device.

This guide will run through different forms of malicious software that could end up on your iOS or Android handset, what the warning signs of infection are, and how to remove such pestilence from your mobile devices if it is possible to do so.

There are many different tweaks available that can bypass jailbreak detections in apps. Some of these tweaks work well with some apps while they may not work at all with others. However, a new kernel-based bypass has now been released for iOS 13 which, so far, seems to work with a very wide range of apps, including Fortnite and PUBG.

To bypass iCloud activation, you will need to jailbreak the iOS device. UnlockGo will start to download the right jailbreak package for your device. You can check the full guide to see how to jailbreak iPhone on Windows and how to jailbreak iPhone on Mac here.

If your device has enabled Screen Time, you will be subject to various restrictions when using your phone. Forgot Screen Time and no idea how to do? Follow the below guide to bypass Screen Time passcode.

Second option is to Enhanced jailbreak detection (Enabled or Disabled). I think, for security reasons, this should always be set to Enabled (jailbroken devices will be marked as not compliant device).

Many acceptable use policies (AUPs) explicitly state that rooted devices are not allowed to access corporate networks, applications and data. As discussed in more detail below, IT admins may also use rooting or jailbreak detection capabilities within their mobile device management (MDM) solution to red-flag any compromised devices enrolled. Even if these policies and protections are not in place, users who are aware their device is rooted should think twice before using that phone for business purposes.

Jailbreaking your iPhone can open up your iPhone to new apps and ways to customize your iPhone. But sometimes it can be hard to do and some people will be cautious and decide not to jailbreak their iPhone because of some of the negatives involved.
