To get started, youвЂ™ll be given a 7-day free trial.macOS supports developing Flutter apps in iOS, Android, and the web (technical preview release). App.io comes with cool features and capabilities, allowing you to perform all required actions and tests without any issues. Since Mac is an Apple product, it will integrate remarkably well with this iOS emulator. The Xcode IDE combined with the Swift programming language make developing apps easy and fun.Open Xcode and click on the Xcode tab -> Open Developer Tool -> Simulator How to launch Android Emulator from Terminal To see the the Android SDK location run this command.OS X & iOS Reverse Engineering: How to Reverse Engineer an iOS App & OS X SoftwareNow closed, App.io is an emulator that is compatible with both Windows & Mac. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch.

Now letвЂ™s talk about the macOS and iOS reverse engineering tools that can help you on this journey.Restoring Classes вЂ“ Useful Tips for Software Reverse Engineers Software reverse engineering toolsBelow are standard command-line tools for reverse engineering iOS and macOS apps. This file is located at the following address: /System/Library/Caches/com.apple.dyld/.These are the basic things you need to know about before doing any reverse engineering. CachesNowadays, all system frameworks and dynamic libraries are merged into a single file called the shared cache. In addition, itвЂ™s good to be familiar with calling conventions and some things specific to ARM-based systems on a chip (SoC), like thumb mode and opcodes format. Mobile devices use ARMv7, ARMv7s, ARMv8-A, ARMv8.2-A, ARMv8.3-A, and ARM64 CPUs.Knowledge of instruction sets is important when reverse engineering algorithms. Modern desktop devices usually use x86-64 CPUs.

nm is a console tool for browsing names and symbols in mach-o executables. It displays specified parts of libraries and object files. otool is a console tool for browsing and editing in mach-o executables. Lldb allows you to debug code on both actual iOS devices and simulators. You can use this tool to reverse engineer and debug code written in C++, Objective-C, and C. lldb is a powerful debugger used in Xcode.

The key difference is that MachOView does have a GUI, so you can browse the structure of mach-o files in a more comfortable way. ThereвЂ™s also a paid version, IDA Pro, which supports a wider range of processors and plugins.MachOView is a utility that works similarly to the otool and nm console tools. The program has a free evaluation version with limited functionality. ItвЂ™s a cross-platform tool that runs on macOS, Windows, and Linux.IDA can be used for disassembling software designed for macOS, Windows, and Linux platforms. IDA is a disassembler and debugger thatвЂ™s suitable for performing complex research of executables. It provides comprehensive information on code signatures and allows for creating and manipulating them.In addition, there are several third-party reverse engineering utilities:LetвЂ™s look closer at each of these utilities.IDA (Interactive DisAssembler) is one of the most famous and widely used reverse engineering tools.

Hopper was designed for Linux and macOS and works best for retrieving Objective-C specific information from the analyzed binary.Dsc_extractor is AppleвЂ™s own open-source tool for extracting libraries and frameworks from dyld_shared_cache. Similarly to IDA, Hopper has a free version with a limited set of features in addition to a paid version. In particular, class-dump creates declarations for classes, categories, and protocols.Hopper is an interactive tool for disassembling, decompiling, and debugging software and applications. With class-dump, you can get pretty much the same information as from otool but in the form of standard Objective-C declarations. MachOView is free to use, but unfortunately, it isnвЂ™t always stable.Class-dump is a free command-line utility for analyzing the Objective-C segment of mach-o files.

The human-readable selector is a great hint for understanding executable code. The selector is the key for searching implementations by name. ItвЂ™s impossible to find a direct call to a method implementation. It can be customized with the help of scripts and plugins written in Java or Python.Id -(id self, SEL _cmd, int value) As we can see, this is an almost regular C function except for its unusual name that contains вЂњ+вЂќ or вЂњ-вЂќ (which distinguishes static methods from non-static methods), the name of a class, the selector string, and two extra arguments ( self and _cmd).From this point of view, the main purpose of the objc_msgSend function is to find the implementation for a given selector and object and call it by passing all specified arguments.The described approach brings at least two specific nuances into the reverse engineering process: Ghidra can be used as a decompiler, as well as a tool for performing such tasks as assembling/disassembling, graphing, and scripting code. It supports macOS, Windows, and Linux.

The executable can be obtained in an obvious way from an application.And when you decompile an IPA file, itвЂ™s just a regular zip archive with a certain structure. Getting an executable to reverse engineerFor macOS software, the simplest case is reverse engineering an executable from an IPA file or an app. For example, the structure of the Code Signature part of mach-o can be understood by inspecting the codesign tool, whose sources are publicly available. A lot of things are available as source code on this platform. Reversing open-source codeBefore reverse engineering anything, check out the Apple Open Source website.

Reversing emulator binariesIf thereвЂ™s no chance to get binary from a device, thereвЂ™s still a possibility to get it from an iOS simulator. If jailbreaking is not an option, thereвЂ™s still a possibility to get the file from the filesystem using the Document Interaction functionality. Usually, we need to have a jailbroken device. In such form, any executable can be traced by any reverse engineering tool described above.A more tricky case is reverse engineering the iOS part.
