![]() This new version of Hopper is able to decode the mangled Swift names. Hopper can use LLDB or GDB, which lets you debug and analyze the binary in a dynamic way (Intel CPU only).īased on an advanced understanding of the executable Hopper can present a pseudo-code representation of the procedures found in an executable. Hopper is specialized in retrieving Objective-C information in the files you analyze, like selectors, strings and messages sent. Most of the Hopper features can be invoked from Python scripts, giving you the ability to transform a binary in any way you want.Įven if Hopper can disassemble any kind of Intel executable, it does not forget its main platform. Once a procedure has been detected, Hopper displays a graphical representation of the control flow graph. Hopper analyzes function's prologues to extract procedural information such as basic blocks and local variables. With the Hopper SDK, you'll be able to extend Hopper's features, and even write your own file format and CPU support. The macOS version makes full use of the Cocoa framework, and the Linux version makes use of Qt 5. Hopper is perfectly adapted to the environment. Hopper is able to transform the assembly language into a pseudo-code that is easier to understand! You can use its internal Python scripting engine to analyze binaries the way you want (this feature works only with Lion)! Starting from version 2.0, Hopper can even use GDB to debug programs!Īnd, last but not least, unlike all other tools of its kind, Hopper is perfectly integrated into the OS X environment. It will let you disassemble any binary you want, and provide you all the information about its content, like imported symbols, or the control flow graph! Hopper can retrieve procedural information about the disassembled code like the stack variables, and lets you name all the objects you want. Nice and simple output.Hopper Disassembler is a binary disassembler, decompiler, and debugger for 32-bit and 64-bit executables. Have a nice day!Ĭ:\Documents and Settings\Administrator\Desktop\diff>dirĭirectory of C:\Documents and Settings\Administrator\Desktop\diff C:\Documents and Settings\Administrator\Desktop\diff\python make-asm.py Ida_path = os.path.join(os.environ, "IDA", "idaw.exe") ![]() The following script can be used to create the assembly output for all executables in the working directory. In order to use kdiff to diff the binaries you will need the disassembly output generate by IDA. If you need to dig deeper go the BinDiff or DarunGrim route as mentioned by Mick. Most of the time I need a simple visual of the different instructions. Note: I use diffing for writing signatures on malware. I'm a big fan of the kdiff route because it's quick and clean. In the end you'll have a few tabs, Matched functions, Unmatched Functions, Identical Functions. Warning this takes a while and IDA will become unresponsive. idb of the file (I noticed it fails when just diffing an exe) and in the IDA View-A tab go to Edit down to plugins and you should see PatchDiff2 just click on it and choose the secondary. ![]() Open your executables you want to be diffed and save them as.Unzip the two patch2diff zip and in it will be two folders holding two files for Linux and Windows just copy the patchdiff2.p64 and w to your plugins directory located in C:\Program Files\IDA Pro Directory\plugins\ Patchdiff2 supports all processors that IDA can handle and is available in two versions: 32 bit and a 64 bit. Therefore this tool is not made to find similar functions between two different programs. The main purpose of this plugin is to be fast and give accurate results when working on a security patch or a hotfix. Display a flow graph for identical and matched functions.Display the list of unmatched functions (with the CRC).Display the list of identical functions.The plugin can perform the following tasks : PatchDiff2 is free and fully integrates with the latest version of IDA (6.1) on Windows and Linux. PatchDiff2 is a plugin for the IDA dissassembler that can analyze two IDB files and find the differences between both. I'd recommend PatchDiff2 too, if you're using IDA Pro. ![]()
