![]() ![]() IDA 7.2 can disassemble S4īinaries but you must use ida64.app, since ida.app cannot properly disassemble 64-bit code. S4 processors have a 64-bit instruction set but use a 32-bit address space in order to save some memory. The Apple Watch Series 4 introduced a unique processor architecture: ARM64_32. ![]() The majority of this post focuses on the various "flavors" of ARM64e binaires, and what can be done to refine their analysis.īefore we get started, let's make a quick note about watchOS. IDA 7.2 fully supports ARM64e, and should be able to disassemble/debug/decompile almost any iOS 12 binary found in the IOS 12 introduced the ARM64e Mach-O file format for binaries that utilise ARMv8.3 PAC extensions. Get a snapshot of the current state of things, address some immediate issues, and get a sense of IDA's trajectory for the future. Here we will push these capabilities to their limit - to This writeup is geared towards the Mac power users (or really anyone interested in reversing Apple binaries) who want to get the most out of IDA's more "Darwinesque" features. With the advent of ARMv8.3-A extensions, new kernelcache and dyldcache formats, and the ARM64eĪrchitecture for iOS, there's never been more demand for a reversing tool that can clear all of Apple's various hurdles. Audience IDA 7.2 was an exciting release for Mac users.
