Josh welcomes back David Bernstein to talk about creating a disaster recover plan. It’s a very timely topic given all the current events. There are more supply chain attacks and compromises than ever before. There are some great resources for this planning, but as David tells us, it’s really not that hard to put some plans together. It’s easy to over-plan, David gives some great tips on getting started with our planning for an eventual incident. ...

Josh talks to Paul McCarty of Open Source Malware about … open source malware. Paul explains why there aren’t many good open source malware datasets.

It’s a fun discussion with a lot of new and interesting problems we all have to deal with.

It’s been a rough couple of weeks for open source There have been some high profile attacks like the TeamPCP events. Anthropic has a new model that’s going to create more security vulnerabilities than anyone can count. The number of security bug reports is going through the roof. AI slop is running rampant through GitHub. And let’s not even try to count all the hot takes from the LinkedInIstas. It’s clear we should never trust open source again, but we should trust someone on linkedin whose company is built on top of all open source and uses AI to do everything. This feels like animal farm but the animals have all been replaced with frozen burritos. All burritos are equal, but some burritos like my linkedin posts! ...

Josh welcomes back Andrew Nesbitt to discuss some recent blog posts he wrote about the challenges of new ecosystems as well as challenges of no ecosystems like C. There aren’t very many people who look at multiple ecosystems in the way Andrew does. He has thoughts on why it’s so hard to create a new ecosystem as well as some of the reasons we don’t see a C language ecosystem. Andrew has a ton of interesting ideas and insight for us about both existing, new, and nonexistent ecosystems. ...

Josh talks to Michael Winser about a talk he gave at FOSDEM as well as his work on Alpha Omega at the Linux Foundation. Michael is approaching open source security in a way that nobody has ever tried before. What if we could fund some really big, really hard projects? It’s not cheap or easy, but he’s getting it done. We spend a lot of the time discussing package registries, which are a huge topic. Michael is doing some amazing work helping package registries which is the first step in a very long journey. ...

Thank you for clicking on the clickbait! What a year it’s been. It seems like open source is under constant attack. The security people don’t know what’s going on anymore. What day is it? It doesn’t matter. The latest open source mess is the popular open source scanner Trivy being compromised, for a month, then other open source projects downstream in the “chain” getting compromised, which will probably lead to more things getting compromised until we get back to Trivy someday. Then I think we have to call it a supply wheel. I’m not sure how these rules work. ...

Josh chats with Brian Fox from Sonatype about their 2026 State of the Software Supply Chain report. Most of the number continue to grow at alarming rates, but there’s some new interesting findings in this one. We discuss end of life and open source which is tough to define. We touch on what using AI with open source dependencies looks like (and why it’s broken), and we discuss the challenge of upgrading your open source dependencies in a way that doesn’t break everything. It’s a great report and great discussion. ...

Josh talks to Luke Hinds, CEO of Always Further, about MCP and agent security. We start out talking about Luke’s new tool, nono which is a sandboxing tool that has AI agents in mind as a use case. We explain what MCP and agents are doing as well as why it’s so hard to secure them. It’s not impossible, but it’s not simple either. We end the show by discussing some of the more human aspects to security and how history may be repeating itself with security folks laughing at new users who don’t know any better. ...

Josh talks to Paul Kehrer and Alex Gaynor, from the Python Cryptographic Authority. Alex and Paul recently published a statement discuss the challenges posed by modern OpenSSL. We discuss the statement and their relationship with OpenSSL. We chat about some of the current features in cryptography, as well as some of what’s coming in the future. It’s a fun conversation that hits on a lot of great points.
