I was looking for some faces that I found back here :)

macOS reverse engineering code sign

typical saturday!

test(lib/cli): dsym filetype by tony-go · Pull Request #29 · tony-go/macho_re macho_re is a lightweight command-line tool for parsing and analyzing Mach-O binary files on macOS. - test(lib/cli): dsym filetype by tony-go · Pull Request #29 · tony-go/macho_re

i like to enrich the lib as much as read new stuff in J Levin's book

Hey Apple/macOS/iOS Security Specialists! 👋

I'm looking to connect and have a chat with some of you.

Is anyone interested?

stick this morning, but I still managed to tweak this: https://buff.ly/49crdaS

We're now @vlt.sh here!

I'm sure you're already aware of this resource, but in case others aren't, Marco Ivaldi released some nice weggli rules and wrote a blog showing some vulnerabilities he found with them.

Yes! I spot a lot of stuff like that.

During the last year and half I was working on an Electron replacement. The consecration for my career! Mixing C++, Objective-C, CMake and Javacript.

The project was suddenly stopped! Since then it is really hard to find a project that requires and challenge these skills.

I spent a lot of time understanding how things work embracing new concepts across différents layers.

It gives a sense to what I do regardless the layer I work on: web, systems, application, tooling …

This is the first time since I started software engineering that I am really confused about the path I should follow.

I started doing React, then Node, then I dived into systems programming doing Rust, C++.

After my previous post, I recieved a few comments about ptrace!

I was curious and decided to explore this new track.

In the post:
➡️ I used ptrace to prevent debugger attaching my program
➡️ I dived into xnu sources to reverse-engineer ptrace

This awesome fuzzing blog post by @r00tkitsmm.bsky.social covers a super reliable macOS kernel binary rewriting to instrument any KEXT or XNU at BB or edge level. Mandatory reading for anyone interested in fuzzing whether you use MacOS or not. So many good system internals and fuzzing references!

I created an AsyncAPI friends starter pack. We're not many here yet. Yet! 😄

having a C++ unified API, wrapping platform specific abstracts is one of the most challenging job I had to do!
