License type:	GNU General Public License v2
Description:	PatchDiff2 is a plugin for the Windows version of the IDA dissassembler that can analyze two IDB files and find the differences between both. PatchDiff2 is free and fully integrates with the latest version of IDA (5.6). The plugin can perform the following tasks: - Display the list of identical functions - Display the list of matched functions - Display the list of unmatched functions (with the CRC) - Display a flow graph for identical and matched functions The main purpose of this plugin is to be fast and give accurate results when working on a security patch or a hotfix. Therefore this tool is not made to find similar functions between two different programs. Patchdiff2 supports all processors that IDA can handle and is available in two versions: 32 bit and a 64 bit.

Tool name:	IDACompare	Currently2/5 1 2 3 4 5 Rating: 2.0 (1 vote)
Author:	David Zimmer
Website:	http://sandsprite.com/blogs/index.php?uid=7&pid=185
Current version:	5.4
Last updated:	March 5, 2009
Direct D/L link:	https://github.com/dzzie/IDACompare/raw/master/IDACompare.exe
License type:	Free
Description:	Update: This tool is no longer available for download through the iDefense website. An copy of the installer has been made available by the author. IDACompare is a plugin designed to compare and match up equivalent functions across two IDA databases. IDACompare was primarily designed for analyzing changes across malcode variants, it should also find good use when conducting patch analysis. Once function matches have been made, names can be ported across disassemblies, or sequentially renamed in both. Project also implements a signature scanner, letting you build your own listing of known functions.

Tool name:	DarunGrim	Currently1/5 1 2 3 4 5 Rating: 1.0 (1 vote)

License type:	Free / Open Source
Description:	DarunGrim is a binary diffing tool. DarunGrim is a free diffing tool which provides binary diffing functionality. Binary diffing is a powerful technique to reverse-engineer patches released by software vendors like Microsoft. Especially by analyzing security patches you can dig into the details of the vulnerabilities it's fixing. You can use that information to learn what causes software break. Also that information can help you write some protection codes for those specific vulnerabilities. It's also used to write 1-day exploits by malware writers or security researchers.  This binary diffing technique is especially useful for Microsoft binaries. Not like other vendors they are releasing patch regularly and the patched vulnerabilities are relatively concentrated in small areas in the code. That makes the patched part more visible and apparent to the patch analyzers. There is a "eEye Binary Diffing Suites" released back in 2006 and it's widely used by security researchers to identify vulnerabilities. Even though it's free and opensource, it's powerful enough to be used for that vulnerabilities hunting purpose. Now I'm releasing DarunGrim2 which is a C++ port of original python codes. DarunGrim2 is way faster than original DarunGrim.

Description:	pynary will become a powerful platform independent framework for binary code analysis. The initial goal is to the implementation of function signature matching using graph isomorphism and an extensible 'write-your-own-heuristic' model to allow tweaks for particular targets. It will also identify standard library global constants and structure where possible. Once the initial goal is achieved, a number of cool features are planned: * stack frame analysis * un-inliner * exception handling parsing/analysis * 'functionally equivalent' matching * c++ template function matching * meta-data transfer between IDBs * c++ class reconstruction (with/without RTTI) * ...  This project is still in its infancy, and looking for volunteers.

Tool name:	asmDIFF	Currently0/5 1 2 3 4 5 Rating: 0.0 (0 votes)
Author:	Michael Willigens, Rene Laemmert
Website:	http://duschkumpane.org/index.php/asmdiff
Current version:	1.1
Last updated:	August 28, 2012
Direct D/L link:	N/A
License type:
Description:	asmDiff is an binary assembly search, diff and disassembly tool. It supports Windows PE (exe/dll) and Linux ELF binary format compiled for x86 and x68_64 architectures. It is particular useful when searching for asm functions, instructions or memory pointers in a patched, updated or otherwise modified binary.  Features: - Single search mode, if one needs to test one or several addresses by hand. - Supports batch mode updates. A header file (containing lots of hardcoded pointers) and two binary files (old, new) is given as input. asmDIFF can then output a "new" header file for the updated binary. Extremely helpful on reverse engineering projects that get updated. - Can find similar functions in different programs. But this can behave very fuzzy. It was tested on related programs where it workes with moderate success.  - Full diff mode. It prints out the entry points of "new", "modified" and "removed" functions. Currently a full featured WebBased version is available. asmDIFF is also included in mmBBQ (http://duschkumpane.org/index.php/mmbbq) version 3.X and upwards.
