This makes hooking into other app functions (a technique heavily used by ( "Cycript") and other reverse engineering tools) easy. For example, Objective-C allows method invocations to be changed at runtime.

( "Hopper") is a reverse engineering tool for macOS and Linux used to disassemble, decompile and debug 32/64bits Intel Mac, Linux, Windows and iOS executables.īecause Objective-C and Swift are fundamentally different, the programming language in which the app is written affects the possibilities for reverse engineering it. For the more budget-minded reverse engineer, ( "Hopper") offers similar static analysis features. IDA is widely seen as the gold standard for GUI-based interactive static analysis, but it isn't cheap. ( "IDA Pro") can deal with iOS binaries. However, there are some commercial alternatives.

manage simulators, launch apps, take screenshots or collect their logs.īuilding a reverse engineering environment for free is possible. simctl is an Xcode tool that allows you to interact with iOS simulators via the command line to e.g. For more information run `xcrun swift-demangle -help` once installed. swift-demangle is an Xcode tool that demangles Swift symbols. For example you may want to use it to locate and run swift-demangle or simctl. ( "xcrun man page") can be used invoke Xcode developer tools from the command-line, without having them in the path.

Make sure you have the ( "Xcode Command Line Tools") properly installed or install them straight away from your terminal: We'll be using standard tools that come with macOS and Xcode in addition to the tools mentioned above. This way you'll have properly installed ( "Apple Xcode IDE"). # Building a Reverse Engineering Environment for Freeīe sure to follow the instructions from the section "Setting up Xcode and Command Line Tools" of chapter "iOS Basic Security Testing". This tool has been discussed in "(0x04c-tampering-and-reverse-engineering.md#ghidra "Ghidra")" section.

( "Ghidra") is a software reverse engineering (SRE) suite of tools developed by NSA's Research Directorate.
Radare2 supports iOS binaries and many useful iOS-specific features, such as a native Objective-C parser and an iOS debugger. It is built with the Capstone disassembler engine, Keystone assembler, and Unicorn CPU emulation engine. ( "Radare2") is a complete framework for reverse engineering and analyzing. ( "nm") is a tool that displays the name list (symbol table) of the given binary.
It works with Mach-O files and universal file formats. ( "otool") is a tool for displaying specific parts of object files or libraries. ( "MachOView") is a useful visual Mach-O file browser that also allows in-file editing of ARM binaries. Directories or the entirety of dyld_shared_cache can be recursively mass-dumped. It can generate header files from app binaries, libraries, frameworks, bundles, or the whole dyld_shared_cache. ( "Class-dump-dyld") allows symbols to be dumped and retrieved directly from the shared cache, eliminating the necessity of extracting the files first. Removing these unnecessary calls makes class-dump-z nearly 10 times faster than its predecessor. ( "Class-dump-z") is class-dump re-written from scratch in C++, avoiding the use of dynamic calls. It generates declarations for the classes, categories, and protocols. ( "Class-dump") is a command line utility for examining the Objective-C runtime information stored in Mach-O (Mach object) files. Make sure that the following is installed on your system:

Throughout this chapter, we refer to the ( "OWASP UnCrackable Apps for iOS"), so download them from the MSTG repository if you're planning to follow the examples. In this guide, we'll introduce static and dynamic analysis and instrumentation. Unfortunately, this also means that no direct cross-references between methods are available in the disassembler and constructing a flow graph is challenging. The advantage of runtime name resolution is that these names need to stay intact in the final binary, making the disassembly more readable. In Objective-C, object methods are called via dynamic function pointers called "selectors", which are resolved by name during runtime. On one hand, apps programmed in Objective-C and Swift can be disassembled nicely.
