Hopper Disassembler 4.2.1: A Powerful Reverse Engineering Tool for macOS and Linux
Hopper Disassembler is a software that allows you to analyze, disassemble, decompile and debug your applications. It supports various file formats and architectures, such as Mach-O, ELF, PE, ARM, x86, x86-64 and more. It also has a rich set of features that make it a versatile and useful tool for reverse engineering.
In this article, we will introduce some of the main features of Hopper Disassembler 4.2.1, the latest version of the software as of April 2023. We will also show you how to download and install it on your macOS or Linux system.
Features of Hopper Disassembler 4.2.1
Hopper Disassembler 4.2.1 has many features that can help you understand and modify the code of your applications. Here are some of them:
Procedures: Hopper analyzes function's prologues to extract procedural information such as basic blocks and local variables[^1^].
Extensible: With the Hopper SDK, you can extend Hopper's features, and even write your own file format and CPU support[^1^]. You can also find many plugins and scripts created by the community on GitHub[^2^].
Control Flow Graph: Once a procedure has been detected, Hopper displays a graphical representation of the control flow graph. You can even export a PDF[^1^].
Decompiler: Based on an advanced understanding of the executable, Hopper can present a pseudo-code representation of the procedures found in an executable[^1^].
Debugger: Hopper can use LLDB or GDB, which lets you debug and analyze the binary in a dynamic way (only for Mac and Linux hosts, not for mobile devices)[^1^].
Objective-C: Hopper is specialized in retrieving Objective-C information in the files you analyze, like selectors, strings and messages sent[^1^].
Swift: Hopper is able to decode the mangled Swift names[^1^]. No more cryptic names!
Tabs: Use tabs to create workspaces with different representations of the file[^1^].
Semantic Coloration: The analysis performed by Hopper separates code from data, memory accesses from stack variablesâ¦ And to help you understand the various discovered objects, Hopper will use a different color to each of them[^1^].
Types: Use the embedded type editor to create your own structures, unions, or enumerated types[^1^]. It greatly helps the understanding of the code to use symbols, rather than raw numbers.
