Jailbreak detection: Necessity for safe working of the device


When it comes to new application security, iOS has traditionally been seen as a secure haven. Every year, this operating system attempts to provide more and more economical upgrades in order to make life easier for its users and the corresponding application and security agency providers. However, for tech-savvy consumers, these timely upgrades may not be sufficient, and there will always be those who believe that there is potential for more progress. As a result, the word “jailbreaking” was coined.

What Exactly Is ‘Jailbreaking’? ‘Jailbreaking’ is the method by which a user gains access to an operating system’s administrative commands and capabilities. It grants the ability (or authorization) to change or substitute application software, files, and settings, as well as remove pre-installed applications and execute specialized software (“apps”) that need administrator-level privileges. Wandera noted a 50 percent rise in the number of jailbroken smartphones from the previous year in a 2020 study of 425 million devices, a significant spike!

The term “jailbreak detection” refers to the program’s ability to determine it isn’t really running on a jailbroken device. The goal of jailbreak monitoring is to make the software run on a non-jailbroken phone so that the hacker does not get further permissions, which limits different tools and approaches like reverse engineering, and it allows an app to prevent several vulnerabilities.

Two types of Jailbreak:

  • Bypassing One-Time Jailbreak Detection One-time jailbreak detecting bypass enables the pentester to securely circumvent the jailbreak identification for the particular application, implying that the pentester only has to surpass the jailbreak detection once. Pentesters, for example, can utilize the Liberty program to permanently avoid jailbreak detection. When you use the liberty program to avoid jailbreak detection,
  • Bypassing Run-Time Jailbreak Detection Run-time jailbreak verification bypass enables the pentester to avoid jailbreak detection throughout the testing process. This implies you may change the value during runtime, but you’ll have to do it again and again to avoid the jailbreak detection; it’s not permanent. For example, we may utilize Frida and Objection to avoid jailbreak detection at runtime. When you use Frida and Objection to avoid jailbreak detection, it only functions till you run the Frida or objection again. When you disable the Frida or other relevant programs, the device starts recognizing that it is jailbroken again.

Apple places limitations on which applications may be loaded on a device. Furthermore, without authorization, no programme may access data and information on the phone or perhaps another app. Because of Apple’s restricted administrative rights, this limits the possibilities of an app. Jailbreaking enables a person to circumvent license conditions and get key administrative powers. This allows the hacker to do the following:

  • Remove any manufacturer-imposed limitations on software and programs. This, in turn, permits the installation of programs that would otherwise be unavailable on jailbroken smartphones.
  • Replace or modify any application, configuration, or file.
  • Install modifications and themes on jailbroken iPhones and iPad phones via unauthorized App stores such as Cydia.
  • Get free in-app purchases and premium applications.

Game hacking and cheating

Furthermore, as an iOS programmer, you may wish to jailbreak your Ios smartphone in order to test your applications, install software on phones, and evaluate the app’s security level.

It’s also simple to understand how jailbreaking may endanger developers like you. A penetrator may quickly circumvent all of your hard work, time, and money spent on establishing an app.

Why is it difficult to detect jailbreaks?

Hackers employ a variety of techniques to achieve their objective of jailbreaking devices. Furthermore, there are several sorts of prisons, and each has a unique set of detection methods. Furthermore, the detection techniques themselves vary over time, which means that once a prison identifies a device’s condition, the next time a user reboots the gadget, they may be in a new form of jail. The detection techniques for jailbreaks can also vary with each release of iOS, making it impossible to forecast what the detection process will look like.

How Is Jailbreak Detection Performed?

One critical factor on which iOS detection with jailbreaking might rely is determining whether the app requests more services and app data than the Apple operating system allows. The app may also hunt for other programs, such as Cydia, which is only available on jailbroken smartphones.

Methods for Detecting Jailbreaks

To prevent jailbreaks, you might employ a variety of detecting methods. Many of them are fairly simple, and these are generally the ones that hackers can readily circumvent. Some complicated procedures are more difficult to avoid. We’ll take a look at a couple of them below:

  • Booting

This iOS detection is present on all smartphones. When you launch or reboot your device, the program tests to see if all of the activities, apps, and info are compliant with Apple’s rules and privacy policy. This is similar to a required jailbreak detection approach.

Any app that does not comply with Apple’s administrative standards will be disabled. As a result, certain apps must avoid jailbreak detection each time they are used on a jailbroken device.

  • The File System

All data and files in the computer are kept in precise locations with defined names. When a device gets jailbroken, the files stored on it change. They could be renamed, modified, or even deleted. This modification to the file system

  • Extra Directory Permission

When a phone is jailbroken, the permissions that specific files and folders have may be altered. This additional accessibility to administrative rights indicates that the device has been jailbroken.

  • A large /etc/fstab file

This is the folder that Apple devices use as a mount point. When a phone is jailbroken, several entries are often written to this file, boosting its size. Another approach to identifying the existence of a jailbroken device is to have a huge /etc/fstab file.

  • Apps that have been jailbroken

Certain applications are only available on jailbroken smartphones. Cydia (an app store), Frida (a tool used by app makers and reverse engineers), and so on.

  • Other Pathway Files

Certain programs’ data is confined to a certain folder on the Apple device, generally the Applications folder. The app can generate and save data in those other files in the system directory on a jailbroken smartphone.

These are only a few methods for detecting jailbreak on iOS devices. However, hackers are always seeking ways to circumvent jailbreak detection techniques and obtain access to data. It is critical to understand how this might happen in order to successfully prevent your apps from getting jailbroken. Appsealing is a website where one can find software-related content.
