In this episode, Josh and Otto dive into the world of Debian packaging, exploring the challenges of supply chain security and the importance of transparency in open source projects. They discuss Otto's blog post about the XZ backdoor and how it's a nearly impossible attack to detect. Otto does a great job breaking down an incredibly complex problem into understandable pieces.

Actually finding vulnerabilities using AI with Joshua Rogers
I chat with Joshua Rogers about a blog post he wrote as well as some bugs he submitted to the curl project. Joshua explains how he went searching for some AI tools to help find security bugs, and found out they can work, if you're a competent human. We discuss the challenges of finding effective tools, the importance of human oversight in triaging vulnerabilities, and how to submit those bugs to open source projects responsibly. It's a very sane and realistic conversation about what AI tools can and can't do, and how humans should be interacting with these things.

Sustaining Package Repositories with Brian Fox
Brian Fox discusses the challenges and future of open source package repository infrastructure. We discuss the complexities of managing public registries, the impact of overconsumption, and the importance of sustainable practices in the open source community. Brian tells us how organizations can reduce their footprint and contribute to a more balanced ecosystem. The package repositories cannot continue to be the world's CDN.

Arch Linux Security with Foxboron and Anthraxx
Join us for a conversation with Foxboron (Morten Linderud) and Anthraxx (Levente Polyak), members of the Arch Linux security team. We talk about the difficulties of maintaining a Linux distribution, the challenges of handling CVEs, and the dedication of volunteers who keep the open-source community working (and how overworked those volunteers are). We explain what makes Arch a little different, how they approach their security process, and what sort of help they would love to see in the future.

Open Source Security is a media project to help showcase and educate on open source security. Our goal is to give the community a platform educate both developers and users on how open source security works.
There's a lot of good work happening that doesn't get attention because there's no marketing department behind it, they don't have a developer relations team posting on LinkedIn every two hours. Let's focus on those people and teams then learn what they do and how they do it. The goal is to hear from the people doing the work, they know what's up, they have a lot to teach us. We just have to listen.
