Once our environment is set up, we’re ready to get started. If a list of commands related to the tool is returned by the -help call, the tool is most likely functioning properly. A good way to test this in terminal-based tools is to issue the help command, which in most cases will be a variation of -help, -h, or similar. Before we get started, make sure to set up all the tools above and ensure they are functioning correctly. These are fairly straightforward to use and can provide a lot of information related to the binary that we are attempting to reverse engineer. Hopper Disassembler: Hopper is an amazing tool that will allow us to disassemble an executable and inspect the machine-level code that composes the binary.strings: looks for ASCII strings in a binary file or standard input.codesign: Xcode utility that adds signatures to built projects.otool: The otool command displays specified parts of object files or libraries.nm: displays the name list (symbol table) of each object file in the argument list.Tools and Utilities for Reverse Engineering iOS Appsįirst, let’s take a quick look at some of the tools and utilities that we will be using to gain additional knowledge about the app we’re working with: If you don’t have access to macOS you can always grab the ideas portrayed in the contents of this blog and utilize similar tools available in other operating systems to achieve a similar goal. Note that we will be using macOS to perform these tests because it provides the most useful utilities and commands to achieve our goal. These will help us obtain valuable information about the mobile application we’re analyzing. In this blog we will learn the basics of reverse engineering iOS binaries by utilizing some of the more popular tools provided by Apple (Xcode Command Line Tools) and some third-party tools as well. This makes the reversing process slightly more complicated but not impossible by any means. Compared to reverse engineering Android with tools like apktool, jadx and similar, reversing tools for iOS are scarce due to security measures implemented by Apple and iOS being less open source in general. Reverse engineering iOS mobile applications is no simple task.
