zynamics Objective-C helper script has moved to Google Code ==================================++======================= This repository has moved to Google Code: zynamics Objective-C helper script Description ----------- This is an idapython script that analyzes ARM/Objective-C files in order to patch calls made to msgSend(), in order to have a better callgraph and more useful cross references. A bit of extra information can be found on: Also fixObjectiveCx86 implements a port that works on x86 binaries, as Vincenzo explains in this other blog post: Prerequisites ------------- The script has been developed and tested using IDA 5.6 and idapython 1.3.0 but it should work with older versions. Usage ----- Just open the target executable file or IDB and run the script. If you are working with iPhoneOS binaries you will find your target inside the IPA file. And remember that applications downloaded from the AppStore have the code section encrypted, so you will need to decrypt it before running the script or trying to analyze it. After running the script is recommended to make IDA re-analyze the program to get the correct assembly listings and cross references. In order to do that, inside IDA go to Options->General->Analysis and then click on "Reanalyze Program" WARNING: This script modifies the IDA DataBase by creating new segments and patching code. If you don't know the implications of this, it is a good idea to have a backup of the database. License ------- The Objective-C helper script is GPLv2-licensed. If you prefer to distribute code from the script under another license please contact us to learn about re-licensing options.
