Together with @pnolsec and @ms_s3c we just published version 2.0 of Nautilus, our grammar fuzzer. It's now compatible w AFL++, can fuzz binary only targets, supports binary formats and scripting for non context free grammars & much more. Get it at: github.com/nautilus-fuzz/…

Big thanks to everyone who attended my thesis defense. If you missed it, here's a recording. I cover important topics like: * Why (human) memory matters when programming * How the Rust borrow checker works * How to make a lemon meringue pie youtube.com/watch?v=BrVk97…

The regex crate is vulnerable to denial of service attacks when parsing untrusted regexes (CVE-2022-24713). We released version 1.5.5, fixing the issue. Read the advisory: blog.rust-lang.org/2022/03/08/cve…

Since a number of you have asked, here are the super-beautiful slides of Nikolas' Ph.D. defense for you to watch and remix. Enjoy! docs.google.com/presentation/d…

My student Nikolas Havrikov defended his Ph.D. thesis today! Nikolas' main contribution is _k-paths_, a means to assess and ensure structural input diversity in grammar-based fuzzing. Congratulations, Dr. @havrikov! 🎓🧑‍🎨🎉🥲 publications.cispa.saarland/2971/

So I built CVEtrends.com 

- data comes from Twitter + NIST NVD APIs
- back-end: Python, Flask, PostgreSQL, and Redis
- front-end: React + Bootstrap

It's a quick MVP, but let me know your thoughts and feedback...

can't agree more

Linux is a kernel which you can't even attach debugger to, sprinkle breakpoints here and there and step through its code. Not even its kernel modules. This is literally the opposite of "the best", especially if you're a developer. Don't @ me.



ms's ebpf is based on ubpf, i run ubpf with afl for several minutes, a lot of crashes...

In January I found, exploited, fixed and responsibly disclosed Linux kernel vulnerabilities in virtual sockets. Public announcement: seclists.org/oss-sec/2021/q… My PoC exploit gains LPE on Fedora Server 33 for x86_64 bypassing SMEP and SMAP. I'll share all the details later. Demo!
