Uncovering Apple Vulnerabilities: diskarbitrationd and storagekitd Audit Part 3 Exploring CVE-2024-27848 & CVE-2024-44210: How macOS vulnerabilities in storagekitd allowed privilege escalation, how they were exploited & Apple’s patch.

Wasn't that good due to my lingering plantar fasciitis issue. But that is life, sometimes there are low moments, and coming out of those will make you stronger. Hopefully things will get better next year. ⛰️🏃

📣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

We are doing again a community run tomorrow. We will meet at the lobby, at the “Aloha” sign at 8AM, and run about 5k north on the beach and then back. #OBTS10k #OBTS

Entering last day of trainings with my colleagues from @kandji.bsky.social . There is always something new to learn in this field, and it’s great to learn directly from iOS experts @naehrdine.bsky.social and Sn0wfreeze #OBTS

FADE DEAD | Adventures in Reversing Malicious Run-Only AppleScripts - SentinelLabs We show how to statically reverse run-only AppleScripts for the first time, and in the process reveal new IoCs of a long-running macOS Cryptominer campaign.

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.

Reverse Engineering iOS 18 Inactivity Reboot Wireless and firmware hacking, PhD life, Technology

How does the new iOS inactivity reboot work? What does it protect from?

I reverse engineered the kernel extension and the secure enclave processor, where this feature is implemented.

Paged Out! #5 is out – enjoy! pagedout.institute
And if you like the cover, we have wallpapers!

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!

@theevilbit.bsky.social 's Apple Disk-O Party

#Apple added three new rules for XCSSET - a #malware we’ve not seen since 2021 - to #XProtect this week as DubRobber F, G & H in v5282. Curious, to say the least.

low detection rates on macOS Amos malware on virustotal

Bunch of new Amos/Atomic #macOS #infostealers if you pivot off ```behaviour_processes:"sh -c curl -s https[:]//api.ipify[.]org/?format=text" tag:macho```
Low detections on V(h/t x.com/malwrhuntert...) #malware #apple #cybersecurity

Apple M4 devices can't virtualize macOS versions prior to 13.4. Hopefully this will get fixed. More info here:

BlueNoroff Hidden Risk | Threat Actor Targets Macs with Fake Crypto News and Novel Persistence SentinelLabs has observed a suspected DPRK threat actor targeting Crypto-related businesses with novel multi-stage malware.

Last week, we released new research about new Mac #malware with TTPs consistent with suspected DPRK #APT BlueNoroff. s1.ai/BNThief. This week, friends-of-NK say we’re shills for US gov. 😂 easternherald.com/2024/11/10/s...
Hate to break it to ‘em, but that ain’t how we roll. 😆
