Fuzzing Linux Kernel Modules, with Slava Moskvin

Stream by @slava_moskvin hosted by @steph3nsims about building a custom fuzzer to rediscover CVE-2025-0927 in the HFS+ filesystem implementation.

Slava started with a simple fuzzer implementation and then improved it step-by-step by adding coverage collection, proper seed generation, mutations, etc.

The source code of the fuzzer is public.

I'm considering to learn PIC programming. Please send help!

Want to learn about Chrome exploitation and the role of WebAssembly in it?

In our new article, we'll break down the world of WASM, how it interacts with V8, and use CVE-2024-2887 as a case study to show how flaws in WASM can lead to remote code execution.

"Exclusive: Meta won't tweak pay-or-consent model further despite risk of EU fines, sources say"

https://www.reuters.com/sustainability/boards-policy-regulation/meta-wont-tweak-pay-or-consent-model-further-despite-risk-eu-fines-sources-say-2025-07-11/

IMO pay-or-consent is a reasonable model for #adtech, but if Meta implements that *and* pays fines, that's good enough for me!

We just updated our bug bounty hall of fame to include the great security researchers from the last two quarters. Thank you for securing the best #Firefox yet :)

in the interest of helping other small publications, i want to pass along a request for elpis zine, an online zine about the small web, retro tech, and alternate protocols that recently celebrated its 10th issue!

for their next issue, they want to focus on #women of the #internet: "who, one way or another, influenced the creation of the modern Internet, which is why the modern World Wide Web looks exactly like this."

from elpis:

These are women who are at the forefront of the attack and work on the technologies that surround us. These are women who have influenced design, content, and politics. But we're not just talking about the modern Internet, we're also talking about the small web.

There are legendary women here, too. We want to write about you, about your sites, if you have ideas about whom we can also write about, or links to pages (feel free to give your sites), that's cool! We'll publish them.

the editors are looking specifically for "ideas about who can be written about from the great women who influenced the modern Internet (designers, programmers, and so on)." there's so many women in internet #history that we must keep their stories going! <3

the editor of the zine, turboblack, is a 32-bit cafe member and a passionate member of the independent web. :) i hope you appreciate this departure to spread some internet-focused publication love!

I'm pleased to announce a new version of the Rust bindings for IDA Pro! With: - Improved strings, metadata, and core APIs. - Support for the names API. Thank you to @raptor.infosec.exchange.ap.brid.gy & Willi Ballenthin for contributing! Docs: idalib.rs Code: git.idalib.rs

There’s an entire rant buried in here but, in short, I absolutely agree.

📣"Debuggers 1103: Introductory Binary Ninja" is released!📣
https://ost2.fyi/Dbg1103

This class by Xusheng Li of Vector 35 @binaryninja provides students with a hands-on introduction to the free version of Binja as a debugger, thus providing decompilation support!

Like all current #OST2 classes, the core content is made fully public, and you only need to register if you want to post to the discussion board or track your class progress. This mini-class takes approximately 2 hours to complete, and can be used as standalone cross-training for people who know other reverse engineering tools, or by students learning assembly for the first time in the https://ost2.fyi/Arch1001 x86-64 Assembly class.

"Engineers from Apple & Google have proposed patches in the GNOME gitlab issues, but neither has had a fix applied to the git repo since there is currently no maintainer for libxslt."
