    Sharing a new demo + an article on BlueKeep dissection (CVE-2019-0708) using REVEN. See how data Tainting, Memory History, and its Python API streamline the RE process to quickly and accurately analyze the root-cause and behavior at the system level.

    If you’re tired of hearing about crypto32, elliptic curves, and other CVE-2020-0601 shenanigans, have a read over our new blog post on Windows’ Intel CET implementation in the face of SetThreadContext and NtContinue. Come for the exploit mitigation, stay for the XState Internals.

    I've developed a new technique for bypassing firewalls/NATs and producing full TCP/UDP session to targeted user. Anyone have RCE for a service that's typically only run behind NATs (eg desktop software like Sonos, Spotify, Dropbox, etc which bind to *) and want to merge projects?

    Starting today, Twitter will preserve JPEGs as they are encoded for upload on Twitter for Web. (Caveat, cannot have EXIF orientation) For example: the attached photo is actually a guetzli encoded JPEG at 97% quality with no chroma subsampling.

    Here is an exploit chain I wrote for Firefox that gets RCE via CVE-2019-9810 and escape the sandbox with CVE-2019-11708/CVE-2019-9810. Once compromised, it drops a payload and injects privileged JS code in already/newly created tabs.

    Here is a recent writeup that I did. It's not as indepth as I want. I'll write a definitive guide for hunting these bugs starting with 0 knowledge when I'm home in a few weeks. I'll also upload all my pocs to github, including recent bugs. I'm pissed. Bye

    Introducing the fzero fuzzer! A target-architecture-agnostic grammar-based fuzzer (inspired by F1). With no input size constraints, multi-thread support, and all Rust code for no corruption bugs. 5x faster than the worlds fastest grammar-based fuzzer ;D
