Welcome back, hackers!

After a long break, we’re relaunching 0x00sec and opening the doors to what it was always meant to be: a place for hackers, researchers, students, and curious minds to share real work, learn from each other, and push their skills forward.

To kick things off, we’re publishing two new articles that set the tone for what we want this site to be about.

First, Malwareless Initial Access through Web and API Exploitation takes a grounded look at red team work without the usual obsession over implants and tooling. It walks through a real engagement focused on achieving an objective using careful testing and exploitation.

Second, Below Local Privilege Escalation Vulnerability: A light look at CVE-2025-27591 digs into a Linux LPE in the below resource monitor. It breaks down the vulnerable code, and shows how the issue can be exploited in practice. Technical, but approachable.

These two pieces reflect what we want more of: practical research, clear thinking, and content written by people who actually did the work!

What else is coming back?

Forums
The forums are live again. This is a fresh Discourse instance and a clean slate. Use it for longer-form discussions, sharing research, asking for help, posting write-ups, or just talking shop. We’ll be moderating and keeping things civil, but the direction of the forum is up to the community. You can browse historical forum posts at the 'Archive', link at the top of the page.

Articles and spotlight content
The new front page at https://0x00sec.org will feature high-quality submissions from core contributors and the wider community. Topics can range across penetration testing, reverse engineering, fuzzing, incident response, forensics, strategy, CTFs, conferences, and anything else that moves the field forward.

Chat
We’re also active on Discord. It’s a relaxed place to meet people at all experience levels, collaborate, and keep conversations moving in real time. Mods and admins are easy to find there if you have questions, feedback, or ideas.

Get involved

We’re actively looking for contributions, feedback, and suggestions. If you’ve got research to share, an idea for an article, or thoughts on what you’d like to see from 0x00sec next, we want to hear it.

You can reach us at hello [at] 0x00sec.org, join the forums, or drop into Discord.

As the community grows, we’re hoping to organize challenges, CTFs, and other events driven by the people who show up and participate.

Thanks for being here.
