Hobbyist Maintainers with Thomas DePierre
Open Source Security
Thomas DePierre joins Open Source Security to discuss the central idea from his blog post, "You are all on the hobbyist maintainers turf now," exploring the massive disconnect between the corporate world that consumes open source and the hobbyist community that actually produces it. The conversation reveals this isn't a new problem, but a long-standing reality whose consequences for security, stability, and the future of software we are only now beginning to truly confront.

STIG automation with Aaron Lippold
Open Source Security
I chat with Aaron Lippold, creator of MITRE's Security Automation Framework (SAF), to discuss how to escape the pain of manual STIG compliance. We explore the technical details of open-source tools like InSpec, Heimdall, and Vulcan that automate validation, normalize diverse security data, and streamline the entire security authoring process.

Ecosyste.ms with Andrew Nesbitt
Open Source Security
I recently chatted with Andrew Nesbitt about his project, Ecosyste.ms. Ecosyste.ms catalogs open source projects by tracking packages, dependencies, repositories, and more. With this dataset Andrew is able to incredible insights into the world of open source. We chat all about how Ecosyste.ms works and how he manages to wrangle all this data.

Curl vs AI with Daniel Stenberg
Open Source Security
Daniel Stenberg, the maintainer of Curl, discusses the increase in AI security reports that are wasting the time of maintainers. We discuss Curl's new policy of banning the bad actors while establishing some pretty sane AI usage guidelines. We chat about how this low-effort, high-impact abuse pattern is a denial-of-service attack on the curl project (and other open source projects too).

Repository signing with Kairo De Araujo
Open Source Security
I recently had a chat with Kairo about a project he maintains called Repository Service for TUF (RSTUF). We explain why TUF is tough (har har har), what RSTUF can do, and some of the challenges around securing repositories. The show notes and blog post for this episode can be found at

Securing GitHub Actions with William Woodruff
Open Source Security
William Woodruff discussed his project, Zizmor, a security linter designed to help developers identify and fix vulnerabilities within their GitHub Actions workflows. This tool addresses inherent security risks in GitHub Actions, such as injection vulnerabilities, permission issues, and mutable tags, by providing static analysis and remediation guidance. Fresh off the heels of the tj-actions/changed-files backdoor, this is a great topic with some things everyone can do right away. The show notes and blog post for this episode can be found at

Embedded Security with Paul Asadoorian
Open Source Security
Recently, I had the pleasure of chatting with Paul Asadoorian, Principal Security Researcher at Eclypsium and the host of the legendary Paul's Security Weekly podcast. Our conversation dove into the often-murky waters of embedded systems and the Internet of Things (IoT), sparked by a specific vulnerability discussion on Paul's show concerning reference code for the popular ESP32 microcontroller.

tj-actions with Endor Lab's Dimitri Stiliadis
Open Source Security
Dimitri Stiliadis, CTO from Endor Labs, discusses the recent tj-actions/changed-files supply chain attack, where a compromised GitHub Action exposed CI/CD secrets. We explore the impressive multi-stage attack vector and the broader often-overlooked vulnerabilities in our CI/CD pipelines, emphasizing the need to treat these build systems with production-level security rigor instead of ignoring them.

Syft, Grype, and Grant with Alan Pope
Open Source Security
I chat with Alan Pope about the open source security tools Syft, Grype, and Grant. These tools help create Software Bills of Materials (SBOMs) and scan for vulnerabilities. Learn why generating and storing SBOMs is crucial for understanding your software supply chain and quickly responding to new threats like Log4Shell.

CVE for EOL with Aaron Frost
Open Source Security
Aaron Frost explores the overly complex world of vulnerability identifiers for end of life software. We discuss how incomplete CVE reporting creates blind spots for users while arming attackers with knowledge. The conversation uncovers the ethical tensions between resource constraints and security transparency, highlighting why the "vulnerable until proven otherwise" approach is the best path forward for end of life software.

info_outlineJosh and Kurt talk about a CWE Top 25 list from MITRE. The list itself is fine, but we discuss why the list looks the way it does (it's because of WordPress). We also discuss why Josh hates lists like this (because they never create any actions). We finish up running through the whole list with a few comments about the findings.
