TL;DR: We disclosed to Chainguard in December 2023 that one of their GitHub Actions workflow was vulnerable to “pwn request”, potentially impacting the integrity of Docker images signed by their cosign Terraform Provider. Fortunately, this ended up being a near-miss incident. We also introduce the Living Off The Pipeline project, which inventories tools used in build pipelines that have RCE-by-Design features.
BoostSecurity News, Press & Events
Last fall, my security research team at BoostSecurity published two articles on supply chain security, initiating an in-depth exploration of the Supply chain Levels for Software Artifacts (SLSA) model. Our first article, “SLSA dip — At the Source of the problem!” concentrated on Source Control Management (SCM) systems like GitHub. There we analyzed the role of SCMs in the supply chain from both Red Team (Attackers’) and Blue Team (Defenders’) perspectives, culminating in an attack tree built using Deciduous, an open-source security decision tree tool. Since then, we gave a talk entitled “Broken Links : Behind the scenes of Supply Chain breaches” at several conferences, including BSides NYC and NorthSec.
