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.

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.

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.

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.

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.

Cargo Semver Checks is a Rust tool by Predrag Gruevski that is tackling the problem of broken dependencies that cost developers time when trying to upgrade dependencies. Predrag’s work shows how automated checks can catch breaking changes before they’re released, potentially saving projects from unexpected failures and making dependency updates less painful across the entire Rust ecosystem.

I got to chat with Lars about a new CI/CD system he’s been working on called Ambient. It sounds really cool and does some very clever things today, with even more things planned in the future. We also spend some time discussing a project he works on called Radicle, a distributed Git forge. It feels like having decentralized infrastructure might be more important than it’s ever been, for some reason. ...

When William Brown posted a rant on Mastodon about the FIDO Metadata Service, it sounded like exactly the sort of thing I wanted to learn more about. So that’s what I did! It’s a fun conversation, William is really good at explaining insanely complicated topics in a way that’s easy to understand. This one is dense, but it’s really interesting, you’re going to learn a ton.

When Luis Villa said he was willing to talk to me about the CRA I knew it would be a great conversation. The number of actual lawyers who also work on open source issues isn’t a large number. Luis is one of those people and he has a ton of knowledge and insight he’s willing to share. Open source legal issues are especially weird because the very nature of the open source license was to hack copyright to give us more rights instead of less. So what did Luis have to tell us about the CRA? ...

I recently sat down with Brian Fox, CTO and co-founder of Sonatype, about a report they recently published about malware in open source ecosystems. This is something that’s not a surprise to anyone paying attention, but there are some things Sonatype is doing in this space that’s very clever. I’ve known Brian for a long time so it was a treat to catch up and see what they found, and what it means for the future. ...
