My PR to Binary Ninja to provide a “Pseudo Objective-C” representation of decompiled code was merged and is available in the latest 5.1-dev builds. For best results, use in conjunction with https://github.com/bdash/bn-objc-extras to hide Obj-C memory management noise and propagate more type information.

New #BinaryNinja plugin: Obfuscation Analysis
Simplifies arithmetic obfuscation (MBA) directly in the decompiler (see demo below). Also identifies functions with corrupted disassembly.
Co-authored by @nicolodev ; available in the plugin manager.

I managed to finally get BYUCTF's pwn/MIPS going. Ghidra gave me a wrong value for __stack_chk_guard and also didn't tell me about it being a pointer. Binary Ninja helped (but had some other issues).
I have updated my writeup, FWIW:

Crazy thought… what if your decompiled Objective-C code looked like Objective-C code?
Today's journey: implementing an Objective-C “pseudo-language” view for Binary Ninja.
My plug-in providing this additional analysis is available at https://github.com/bdash/bn-objc-extras
I've been experimenting with improving Binary Ninja's analysis of Objective-C code recently. Having the ability to hide Obj-C runtime reference counting calls, and apply type information based on [super init] and objc_alloc_init calls can dramatically improve the readability (and in some cases even accuracy!) of the decompiled code.

When performing process injection, one of the most important IOCs that make up behavioural signatures is passing execution to our shellcode. Whilst there are multiple techniques to doing so and this is certainly nothing purely “new” - in this post I want to showcase not just a “new proof-of-concept technique”, but the entire process I went through in hope that this can become a proper addition to a capability developer’s skill set.
