![]() ![]() Additionally, the plug-in is able to automatically rename constants, which further speeds up the analyst workflow. This allows the information to be integrated as seamlessly as possible. The MSDN Annotations plug-in integrates information about functions, arguments and return values into IDA Pro’s disassembly listing in the form of IDA comments. In this blog post we will release a script that does just that, and we will show you how to use it. Frequently switching to the developer documentation can interrupt the reverse engineering process, so we thought about ways to integrate MSDN information into IDA Pro automatically. While analyzing malware samples with the team, I realized that a lot of time is spent looking up information about functions, arguments, and constants at the Microsoft Developer Network (MSDN) website. Motivationĭuring my summer internship with the FLARE team, my goal was to develop IDAPython plug-ins that speed up the reverse engineering workflow in IDA Pro. We hope you find all these scripts as useful as we do. As always, you can download these scripts at the following location. We started this blog series with a script for Automatic Recovery of Constructed Strings in Malware. ![]() I'm assuming that all the OpenSSL functions are in the same area.The FireEye Labs Advanced Reverse Engineering (FLARE) Team continues to share knowledge and tools with the community. Obviously, this is a pain for an entire library. It should then populate the correct type information. Then press N, make sure the name is exactly as it's spelled in the header/.til file, and then press enter. This will bring up your type declaration. Go to one of the OpenSSL functions, and put your cursor on the name. That being said, you should still be able to make use of the. Since the names were already present, it wouldn't count as "auto-generated" to IDA (i.e. sig file using IDA's Flirt utilities.īy default, IDA won't replace existing type information unless it was "auto-generated" upon initial analysis so you've got to reset the type field for IDA to fill in the type info. For that piece you're going to need produce the requisite. til file doesn't tell IDA how to actually recognize that function in order to apply function prototype information. IDA's til files are basically IDA's way of storing type information for particular functions. ![]()
