This functionality already exists in Ghidra. The researcher could define a bit pattern correlating with the beginning of functions in the observed CPU architecture, and search for these patterns in order to identify all code blocks following this rule, which would most likely be a function prologue. In order to resolve this, one can utilize the simple observation that many functions share a similar structure, which can be easily defined by a common pattern. Most of the time, IDA’s default explorer manages to identify all the functions, but sometimes it has some hiccups, especially in the context of raw firmware dumps. I find that in many cases Ghidra performs much better analysis than IDA when dealing with a raw firmware dump. However, I use other programs’ capabilities as well because these have their own benefits.
#USING PLUGINS IN IDA PRO SOFTWARE#
Like many other researchers, my go-to tool for software reverse engineering is IDA Pro. One aspect of efficient initial firmware analysis is to define functions correctly after you have loaded the extracted firmware to an analysis tool (e.g. This can make the initial software reverse engineering task more complex than analyzing a good old ELF executable on a Linux system. It is necessary to consult the processor datasheet in order to load it correctly and perform an initial analysis and that’s before even mentioning luxuries such as debug symbols. When you take a first look at the firmware of an embedded device, you don’t always know what the memory layout is. It is often the first phase when we conduct penetration tests on automotive systems (which are basically embedded devices, but in a car, which is cooler). The task of firmware exploration is well known in the embedded research realm and constitutes a significant part of the vulnerability research process.

I’m sharing this tool on Github ( IDAPatternSearch), and in this blogpost I’ll explain how it works and how to use it. Since I miserably failed to convince them to give Ghidra a chance, I implemented this Ghidra feature on IDA (borrowing Ghidra’s format for bit-patterns). One of these perks is the ability to efficiently locate functions using bit-patterns, according to the CPU architecture – a challenge my colleagues and I often tackle on the Argus research team. Take for example Ghidra, which offers awesome perks when analyzing raw embedded firmware.

I get it, IDA Pro is a powerful tool and has beautiful color schemes, but that doesn’t mean other disassemblers don’t have amazing features that you simply can’t find in IDA. Many security researchers have a monogamous relationship with IDA Pro.
