OCAT - Obj-C ARM Tools
Optimistically, this is a collection of tools for derping around with Objective-C stuff on ARM platforms (iOS binaries). Realistically, this "collection" currently consists of:
This script is designed to parse through the IDA Pro database (IDB) for an ARM Objective-C binary and build method-to-method cross references (xrefs). The basic technique is to parse through the "__objc_methanme" segment, find xrefs to every method name string that come from the "__objc_const" segment, and read function pointers out of the "const" structures.
This is a quick and dirty, unscientific approach. We're taking advantages of the heavy lifting that IDA has already accomplished for us and using it to squeeze out some additional functionality.
CAUTION: This script has the ability to mess up your IDB file in a ways that you will not appreciate. Back up your IDB!
