6/24/2023 0 Comments Hopper disassembler tutorialGetting this pseudo-code can literally be accomplished in just a couple clicks with a tool such as Hopper. Have you ever wondered how people get pseduo-code of some private API like the image below? It's actually very simple and is a great way to chase down those annoying bugs in UIKit or some other binary you don't have source code for. The goal of this post is to bridge the gap for those that have shied away or aren't familiar with reverse engineering. I spend a lot of my time in a tool called Hopper (it's a must have in my toolbox) and while it's an amazing tool, it can seem overwhelming at first. Lately I've seen a lot of people asking "How are you getting that pseudo-code," in regards to radar he filed and I thought this would be a great first blog post of mine as I've been wanting to for awhile. I look forward to seeing more of your work.Hopper + lldb for iOS Developers: A Gentle Introduction Here's a webpage from Intel which discusses these differences along with some of the advantages and disadvantages of both types of analysis.Īgain, thank you for writing this series and for going over more nitty-gritty details that normally get glossed over when people teach this stuff. So disassemblers and decompilers would be tools for static analysis, but debuggers remain tools for dynamic analysis. The difference between static and dynamic analysis is that static analysis studies the program without running it, whereas dynamic analysis studies the program during runtime. I could be misinterpreting this section or be outright wrong, but the definitions for static and dynamic analysis here differ from the most common definitions. Thanks for writing this series! I wish I had something like this series earlier when I was learning about the x86 assembly language and architecture. In our next lesson we will discuss various types of malware. The project will be very basic however it will ultimately showcase the power of Assembly Language and how one can use it to reverse engineer and ultimately provide solutions on how to better design the code to make it safer. At the end of our series, our capstone tutorial will utilize IDA as we will create a real-world scenario where you will be tasked by the CEO of ABC Biochemicals to secretly try to ethically hack his companies software that controls a bullet-proof door in a very sensitive Bio-Chemical lab in order to test how well the software works against real threats. Reverse engineering is much more than just malware analysis. There are other disassembler/debugger tools as well on the market today such as Hopper Disassembler, OllyDbg and many more.Ī disassembler will convert an executable binary written in Assembly, C, C++, etc into Assembly Language instructions that you can debug and manipulate. The most popular tool in the market today is called IDA which is a multi-platform, multi-processor disassembler and debugger. We will not focus on this type of analysis here as we are going to focus on actual disassembled binaries instead however in future courses we will.ĭynamic analysis uses disassemblers and debuggers to analyze malware binaries while actually running them. Static analysis uses software tools to examine the executable without running the actual decompiled instructions in Assembly. The first being static analysis and the other being dynamic analysis. There are two basic techniques that you can employ when analyzing malware.
