Apple has patched a vulnerability I reported that had been present for over a decade. The fix was released in macOS 27.2. CVE-2026-112445 Of all the local privilege escalation (LPE) vulnerabilities I’ve seen, this is probably the easiest to exploit, the most straightforward, and the most bizarre—so bizarre that it makes you wonder whether it was an Apple backdoor. github.com/Mas0nShi/CVE-2026…

The screensharingd bug is a pre-auth, and an amazing bug that LLM enabled clowns killed without understanding it. Releasing a PoC that allows to download files from vulnerable macOS. It’s not super reliable, but the real one is very much. Patch asap! reverse.put.as/2026/07/29/it…

🍎🌁 Big changes to user TCC.db in macOS Golden Gate! It seems that it finally got the protection it deserves. It was moved to: /private/var/containers/Data/ProtectedSystem/[UUID]/Data/Library/Application Support/com.apple.TCC/ You can't access it even with FDA, and likely need "com\.apple.private.security.protected-system-container" entitlement to write to it.

IMO Mysk is not trustworthy. They tried to hype low impact vulns as critical in the past (HTTP icon download). Also... duplicates happen, and Apple always credits you for those. If you can't trust the vendor's decision about first submitter, then don't submit. I did cross check a few of these duplicates with researchers in the past, and Apple was always right.

Today, Project Zero released a 0-click exploit chain for the Pixel 9. While it targets the Pixel, the 0-click bug and exploit techniques we used apply to most other Android devices. projectzero.google/2026/01/p…

A tiny timing flaw in Apple’s core file-copy APIs can put millions of devices at risk 📂🍏 Despite warnings, Apple thought it was “too hard to exploit”—until Mickey Jin developed an exploit that steals secrets in privileged services 👉nullcon.net/berlin-2025/spea… #NullconBerlin2025

🍏 #AppleDevelopers use NSFileManager thinking it’s safe — but @patch1t found a race condition once thought “impossible to exploit.” At #NullconBerlin2025, he’ll show how it works, why CVE-2024-54566 failed, and Apple’s final fix. 👉 nullcon.net/berlin-2025/spea… #iOS #applesecurity

We released our Fuzzilli-based V8 Sandbox fuzzer: github.com/googleprojectzero… It explores the heap to find interesting objects and corrupts them in a deterministic way using V8's memory corruption API. Happy fuzzing!
