Learn 3 easy steps to Protect iOS Apps against Jailbreak Bypass and Jailbreak Hiding tools such as JailProtect, Liberty Lite, TweakRestrictor, KernBypass, and FlyJB.
Jailbreaking is the process of unlocking the iOS operating system on an Apple mobile device. Jailbreaking is a form of administrative privilege escalation, which bypasses Apple’s restrictions, resulting in full administrative control over the OS (the highest level of administrative privilege possible). Jailbreaking is often accomplished by exploiting bugs in Apple’s software/firmware or modifying system kernels to allow read and write access to the file system. Jailbreaking is one of the primary methods/tools for every hacker – both black hat hackers and white hat hackers (eg: penetration testers or security researchers). They all use Jailbreaking in similar ways (to compromise the security model of mobile devices, the operating system, and any app running on the device). The main difference is that black hat hackers have malicious intent, while white-hat hackers generally have non-malicious intent.
Whatever the intent, Jailbreaking makes every hacker’s job much easier by providing a significant advantage to compromise the security model, due to the elevated level of privilege and full administrative control that Jailbreaking enables. You can think of Jailbreaking as a ‘gateway’ hacking tool: In other words, Jailbreaking is a fundamental hacking tool that enables more advanced hacking tools or methods. For instance, jailbreaking makes it easier to use emulators and simulators to hack mobile games. Jailbreaking provides unfettered access to alternative repositories like Cydia, where one can obtain any number of tweaks, mods, fake apps, clones and. more. Jailbreaking makes it easier to disable anti-tampering protections, turn off digital rights management checks, to disable mobile threat detection SDKs in the source code. Jailbreaking makes it easier to run a tool like FRIDA to perform dynamic code injection, function hooking, method swizzling (all methods by which hackers alter the logical control flows of a mobile app to replace intended app behaviors with their own malicious behaviors). Jailbreaking makes it easier to hack in-app purchases, to disable mobile advertising SDKs, to set-up a malware beacon inside the app.
Bottom line: Jailbreaking compromises the mobile security model. It enables hackers to send fake signals, to modify code, to modify the file system, to disable security protections. Any iOS app that runs on a Jailbroken device is in a vulnerable state, where hackers can amplify and increase the magnitude of their attacks – all with less effort.
Hackers use Jailbreak Bypass and Jailbreak Hiding tools to evade Jailbreak detection/protections. As mentioned above, Jailbreaking makes it easier to hack iOS apps and to compromise the mobile security model. So if a mobile app is protected with Jailbreak detection or Jailbreak protection, hackers will try to either bypass the protection or hide the fact that the device is Jailbroken. If they can evade detection, then they can operate in a Jailbreak state longer (doing whatever activity they used Jailbreak to achieve in the first place): such as play the game for free longer, or use more advanced or automated tools like emulators to modify in-app purchases, use FRIDA to inject malicious code, to use IDA-Pro to create a call graph to trace the app’s source code, to modify app workflows, or send fake signals to unsuspecting users to make their attacks seem more legitimate/credible.
Hackers combine Jailbreak tools with Jailbreak bypass tools to kill two birds with one stone. For example, hackers combine the use of Jailbreak tools like CheckRa1n, Unc0ver, Zylon, PlankFilza, Chimera, etc, (which they use to Jailbreak iOS), alongside special-purpose Jailbreak Bypass or Jailbreak hiding tools like FlyJB, JailProtect, Liberty Lite, TweakRestrictor, KernBypass. The first set of tools is used to achieve Jailbreak state, while the second set of tools is used to conceal the fact that the device is Jailbroken or to bypass Jailbreak protection/detection mechanisms in the app.
Below is a non-exhaustive list of some of the top Jailbreak, Jailbreak bypass/hiding tools, and how hackers combine those tools for maximum effect.

Appdome Jailbreak Prevention enables an iOS app to protect itself against Jailbreaking and Jailbreak Hiding. You can use Appdome to build Jailbreak Prevention into any iOS app – without coding. When the Appdome-secured app detects that it’s running on a Jailbroken device the app will shut itself down (default behavior) after displaying a message to the mobile user. This protects that app, user, and mobile data from being compromised or attacked by a malicious actor using Jailbreaking.
Please follow these 3 easy steps to add Jailbreak Prevention to any iOS app, which automatically protects iOS apps against the most common Jailbreak bypass and jailbreak hiding tools.
Appdome’s Jailbreak Prevention automatically protects mobile apps against the most common combinations of Jailbreak and Jailbreak hiding tools and combinations.
Congratulations! The app can now defend itself against Jailbreaking and Jailbreak Hiding/Bypass tools.
Appdome’s no-code mobile app security platform offers mobile developers, DevSec and security professionals a convenient and reliable way to protect Android and iOS apps with RASP (Runtime Application Self-Protection), such as Jailbreak Prevention. When an Appdome user clicks “Build My App,” Appdome leverages a microservice architecture filled with 1000s of security plugins, and an adaptive code generation engine that matches the correct required plugins to the development environment, frameworks, and methods in each app.
Here’s what you need to build secured apps with
After successfully securing your app using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
