Static Devirtualization of Tencent VM. There are many others with similar results to ours, we have had the VM devirtualized for several months now. Others are posting full devirt bins, so we feel it is ok to release our research now. back.engineering/blog/31/07/…

In iOS 18.4, Apple introduced a bug in dynamic symbol resolutions for some specific exports. @0xf4b took a long journey down a rabbit hole to understand its root cause. synacktiv.com/en/publication…

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. naehrdine.blogspot.com/2024/…

Our slides about WASM bugs in browsers are now available. Thanks to everyone who helped with the talk.🫡 Hope we can do better next time. 1. BH USA 2024: i.blackhat.com/BH-US-24/Pres… 2. GeekCon Shanghai 2024: geekcon.top/js/pdfjs/web/vie… cc my partners (@p1umer @xmzyshypnc1 @q1iqF)
My Chrome RCE bug(CVE-2024-1939) mentioned in our BlackHat USA 2024 talk was public now. More information not mentioned in the issue will be included in our coming soon slide.🧐 So regret unable to attend Blackhat USA and BugSWAT Vegas in person due to some personal reason.😶
