FLARE IDA Pro Script Series Generating FLAIR function patterns using IDAPython

Par Security Bloggers Network
Le [2015-01-08] à 22:52:02



Présentation : The FireEye Labs Advanced Reverse Engineering FLARE Team continues to share knowledge and tools with the community. This is the third IDA Pro script we ve released via this blog and we ll continue to release these scripts here. Summary ------- This blog describes an IDAPython script to assist with malware reverse engineering. FLIRT signatures help IDA Pro recognize common functions in compiled programs and automatically rename for the reverse engineer. The IDAPython script idb2pat.py generates IDA Pro FLAIR patterns from existing IDB files. You can use it to generate FLIRT signatures for 32- or 64-bit executables loaded into IDA Pro, even if you don't have the typical requirements of an original source or static libraries. Because idb2pat.py is written in Python, you won't need to recompile it after each IDA Pro SDK release. Problem ------- IDA Pro uses Fast Library Identification and Recognition Technology FLIRT signatures to quickly identify compiler-generated and statically linked functions in programs. Once identified, IDA Pro renames the common functions and marks these as library functions to guide the reverse engineer toward more relevant sections of code. For example, without FLIRT signatures, the reverse engineer may encounter the complex function shown in Illustration 1, and work to understand its purpose. With FLIRT signatures enabled, IDA Pro renames the function as printf, and the analyst can likely pass over it. Hex-Rays distributes utilities in the Fast Library Acquisition for Identification and Recognition FLAIR, no relation to the FireEye FLARE team - package to generate custom FLIRT signatures on its website. These utilites operate on static libraries such as .a files on Linux and .lib files on Windows. Reverse engineers can easily teach IDA Pro to identify custom libraries with the FLAIR utilities. Typically the reverse engineer starts by using a utility such as pelf to generate a pattern file that describes major features of each function in the library. They then use the sigmake utility to translate the textual pattern file into a binary signature file. This second step resolves conflicts in the signatures and produces an efficient format that IDA Pro can digest. The reverse engineer can now load the signature file and instruct IDA Pro to rename custom library functions in a statically linked program. For example, during the FLARE-On challenge, some of the successful participants completed the sixth challenge linhax using custom FLIRT signatures. The statically linked Linux executable was stripped, so many common functions appeared mixed in with key functionality. Using the FLAIR utilities on the matching runtime libraries created the FLIRT signatures required to resolve many of the support function names in linhax. Unfortunately the FLAIR utilities only work on static libraries, which makes them most useful when a reverse engineer has access to source code or libraries prior to linking. Usually this is just fine however, there are a few edge cases. For instance, Go binaries are always statically linked to their Go-language dependencies, and it is not possible to build these libraries separately. When I loaded a stripped Hello, World program into IDA Pro, I encountered 1,777 unnamed functions I'd save a lot of time if a majority of those functions could be renamed automatically. Existing Solutions ------------------ For more than a decade, IDA plugins that extract signatures from programs loaded into IDA Pro have been freely available online. Notably, idb2pat and idb2sig are shared library plugins that you can download here. Illustration 2 shows a reverse engineer generating a pattern file from ntdll.dll using idb2sig in IDA Pro. These plugins are fast and well-tested. However, since they are written in C , they must be recompiled with each update to the IDA Pro SDK. Also, many plugins have limited support for 64-bit programs. Proposed Solution ----------------- The IDAPython script idb2pat.py generates FLAIR patterns from IDB files. It works on both 32- and 64-bit programs. It is a very close port of the C idb2sig by mercury, and updated by TQN to Python. Installation and Use -------------------- The script idb2pat.py is provided under the Apache License, version 2.0, and can be downloaded from the FLARE team's Github repository here. Once downloaded, you can run the standalone script directly using IDA Pro's scripting dialog. The script will prompt you for the output file path, and use sane defaults while generating patterns of each function in the current project. These defaults can be tweaked, and sufficient documentation is found in the plugin file. I was motivated to develop idb2pat.py while considering how to reverse engineer Go binaries. As an example, I compiled the Hello, World sample program available on the Go tutorial website here, for 64-bit Linux. The Go compiler includes copious debugging information and symbols in the default executable format, and IDA Pro's analysis helpfully renamed all 1,777 functions in the binary file. However, after stripping the file, IDA Pro was unable to rename any function and I had a difficult time differentiating support code from the main function's disassembly. Illustration 3 and Illustration 4 show the before and after disassembly listings when stripping the Go binary. To help IDA Pro identify support functions, I used idb2pat.py to generate a pattern file from the unstripped binary. Illustration 5 shows the plugin output as the script generated 1,754 patterns. Next, I ran the FLAIR utility sigmake to identify 18 pattern conflicts in the file, and subsequently remove them from the database. This resulted in 1,718 patterns that I translated into a signature file, also using sigmake. I used the following command to invoke sigmake against the pattern file sigmake -ngolang-linux64 helloworld.pat helloworld.sig Then, I opened up the stripped version of the program, applied the FLIRT signature, and watched IDA Pro rename most of the functions. The few functions it missed were due to either the 18 pattern conflicts, or functions with fewer than six bytes of instructions too short to effectively signature . Illustration 6 shows a basic block of an initialization routine when no names are recognized, and Illustration 7 shows the same block after the FLIRT signatures have been applied. The second view shows much more contextual information via the function names. Applying the same signature to other programs in the Go tutorial series also yielded good coverage since many of the support and library functions are the same. I plan on developing a Go program that imports all standard libraries and using this as the source for a comprehensive FLIRT signature for Go. Conclusion ---------- You can use the IDAPython script idb2pat.py to quickly and easily generate function patterns for IDA Pro FLIRT signatures. This helps IDA automatically rename common functions in compiled programs. The script works on both 32- and 64-bit programs, and because it is written in Python, it can be easily updated and modified by users. I hope you'll give this free tool a shot by downloading it from the FLARE team's Github repository
