Moreover, because it’s a command line tool, it integrates very easily with other command line tools that you are likely familiar with, including things like grep, awk, diff and so on. And as we’ll see in the tips below, you can triage a binary with it very quickly indeed!
RAPIDCLICK MAC MALWARE INSTALL
You can install and run it very quickly in a new VM without having to worry about dependencies or licensing (the latter, because it’s free) and it’s much less likely (in my experience) to crash on you or corrupt a file or refuse to start. Radare2 is an extremely powerful and customizable reversing platform, and – at least the way I use it – a great deal of that power comes from the very feature that puts some people off: it’s a command line tool rather than a GUI tool.īecause of that, r2 is very fast, lightweight, and stable. For a rare example of r2 introductory material using Mach-O samples (albeit not malware), I recommend having a look at these two helpful posts: 1, 2.īefore we dive in, I do want to say a little bit about why r2 is a good choice for macOS malware analysis, as I expect at least some readers are likely already familiar with other tools such as IDA, Ghidra and perhaps even Hopper, and may be asking that question from the outset. I’m going to assume that you’ve read at least one or two basic intro r2 posts before starting on the material below. Very few are aimed at malware analysts, and even fewer still are aimed at macOS malware analysts, so they are not much use to us from a practical point of view. However, most such posts are aimed at CTF/crackme readers and typically showcase simple ELF or PE binaries. Such posts will serve you well in terms of learning your way around the basics of installing and using the tool if it’s completely new to you.
There are many introductory blogs on installing and using r2, and I’m not going to cover that material here. Why Use radare2 (r2) for macOS Malware Analysis?įor rapid triage, my preferred tool is radare2 ( aka r2). For those rarer samples that pique our interest and look like they need deeper analysis, we want our triage session to give an overall profile of the sample and indicate areas for further investigation. Ideally, we want to get a sample “triaged” in just a few minutes, where “triage” means that we understand the basics of the malware’s behavior and objectives, collecting just enough data to be able to effectively hunt for related samples and detect them in our environments.

We don’t want to get stuck in the weeds reversing lots of unnecessary code only to find out that the sample really wasn’t worth that much effort! Analysts are busy people, and the majority of malware samples you have to deal with are neither that interesting nor that complicated.
RAPIDCLICK MAC MALWARE HOW TO
We kick off with a walk-through on how to rapidly triage a new sample. We’ll walk through problems such as beating anti-analysis and sandbox checks, reversing encrypted strings, intercepting C2 comms and more.
RAPIDCLICK MAC MALWARE SERIES
In this new series of posts, we move into intermediate and more advanced techniques, introducing you to further tools and covering a wide range of real-world malware samples from commodity adware to trojans, backdoors, and spyware used by APT actors such as Lazarus and OceanLotus. In our previous foray into macOS malware reverse engineering, we guided those new to the field through the basics of static and dynamic analysis using nothing other than native tools such as strings, otool and lldb.
