📣I’m happy to announce that I’m planning to write a brand new “macOS Vulnerability Research” training. 🥳 Considering the amount of work the writing requires it will be available late 2025 or early 2026. It will be Live class only, and likely only once or twice a year.
☀️🏝️This is the day! Don’t miss it if you want to learn how to talk with launchd and how to generically detect XPC exploits. 🔥🔥🔥 #OBTS

Been a while since we've seen #macOS #malware abusing osacompile rather than plain osascript, but #Amos Atomic Stealer is nothing if not adaptable. SHA1: 51ef05c84eea3dde149a5dd3ea9916a824e95afc. A reminder that it's possible (didn't say easy 😅) to reverse compiled #applescript. s1.ai/fadedead

I was featured in PagedOut Issue #5 with my macOS notification forensics article (page 25). I find the whole idea of this magazine pretty cool. Lot's of interesting stuff in there!

Excellent stuff even though i’m not really a phone guy. Love the reversing and the detailed explanation of the process. 👏 👏 naehrdine.blogspot.com/2024/11/reve...
