The word "jailbreak" is a colloquial reference to all-in-one tools that automate the disabling process.ĭeveloping a jailbreak for a given version of iOS is not easy. custom code or downloaded from alternative app stores such as Cydia or Sileo). ![]() The purpose of jailbreaking is to disable iOS protections (Apple's code signing mechanisms in particular) so that arbitrary unsigned code can run on the device (e.g. This is why even official iOS images can't be installed if they aren't signed by Apple, and it makes iOS downgrades only possible for as long as the previous iOS version is still signed. On iOS devices, flashing a custom ROM is impossible because the iOS bootloader only allows Apple-signed images to be booted and flashed. The bootloader may require an exploit to unlock it. Flashing custom ROMs: This allows you to replace the OS that's running on the device after you unlock the bootloader.Exploits aren't required to obtain root access as long as the bootloader is accessible. Rooting: This typically involves installing the su binary on the system or replacing the whole system with a rooted custom ROM.To explain the difference, we'll first review the concepts of "rooting" and "flashing" on Android. IOS jailbreaking is often compared to Android rooting, but the process is actually quite different. It is an enterprise SaaS solution with a per user license model and does not offer community licenses. Testing on an EmulatorĬorellium is the only publicly available iOS emulator. Apps compiled for a real device don't run, making the simulator useless for black box analysis and reverse engineering. Most importantly, emulator binaries are compiled to x86 code instead of ARM code. Unlike the Android emulator, which fully emulates the hardware of an actual Android device, the iOS SDK simulator offers a higher-level simulation of an iOS device. If you don't have access to a jailbroken device, you can apply the workarounds described later in this chapter, but be prepared for a more difficult experience. These devices allow root access and tool installation, making the security testing process more straightforward. You should have a jailbroken iPhone or iPad for running tests. It is also possible to get the UDID via various command line tools on macOS while the device is attached via USB:īy using the I/O Registry Explorer tool ioreg: You can copy the UDID by right clicking on it. ![]() Open Finder and select the connected iOS device in the sidebar.Ĭlick on the text containing the model, storage capacity, and battery information, and it will display the serial number, UDID, and model instead: You can find the UDID of your iOS device on macOS Catalina onwards in the Finder app, as iTunes is not available anymore in Catalina. The UDID is a 40-digit unique sequence of letters and numbers to identify an iOS device. Testing Device Getting the UDID of an iOS device Burp Suite or other interception proxy tool.At least one jailbroken iOS device (of the desired iOS version).Wi-Fi network that permits client-to-client traffic.Xcode and Xcode Command Line Tools installed.Ideally macOS host computer with admin rights.The following is the most basic iOS app testing setup: ![]() This means that you'll definitely want to work on macOS for source code analysis and debugging (it also makes black box testing easier). In addition, the Xcode development environment and the iOS SDK are only available for macOS. iOS Testing SetupĪlthough you can use a Linux or Windows host computer for testing, you'll find that many tasks are difficult or impossible on these platforms. These basic processes are the foundation for the test cases outlined in the following chapters. In this chapter, we'll talk about setting up a security testing environment and introduce basic processes and techniques you can use to test iOS apps for security flaws. In the previous chapter, we provided an overview of the iOS platform and described the structure of its apps. ![]()
