BoostSecurity News, Press & Events

After connecting with dozens of CISOs and CTOs, we've realized there’s a lot of diverging ideas around what software supply chain security even is. Even more so, the range of opinions around how to effectively protect against the unique and expanding kinds of risks is confusing to say the least. And while there are plenty of supply chain security standards around, and plenty of deeply technical supply chain security resources, there wasn't anything talking about it from a business risk level. So, we put together a resource for CISOs and CTOs that explores four categories of risks;

TL;DR: Your trusty Dependabot (and other GitHub bots) might be an unwitting accomplice. Through "Confused Deputy" attacks, they can be tricked into merging malicious code. This doesn’t stop here. It can escalate to full command injection via crafted branch names and even bypass branch protection rules. Plus, we disclose two new TTPs to build upon previously known techniques.

TL;DR: CI/CD remains a stealthy and soft target for supply chain attacks—especially via linters, formatters, build and test tools. This guide breaks down Living Off the Pipeline (LOTP) techniques, where attackers exploit CI tools already present and without modifying the workflow itself—using config files, plugins, and environment variables instead.

TL;DR: We've been quiet lately—despite recent Supply Chain drama—because we wanted a clearer picture before chiming in. Attacks on popular GitHub Actions (tj-actions/changed-files and reviewdog/action-setup) have shocked us, but not surprised us. They simply proved the point we had warned about. Alarmingly, reviewdog automatically promoted “typo-fixers” to maintainers overnight. Combine that with GitHub's audit logging gaps—attackers can update releases leaving no trace—and we've got a real mess. It’s time we reassess our threat models and demand better visibility.

TL;DR: Our deep dive into open source projects’ CI/CD systems has revealed that build pipelines can be just as vulnerable as any other link in the software supply chain. We found hundreds of zero days on open source projects’ build pipelines with our detection at scale and responsibly disclosed them. Jump to the Research at Scale section to learn more.

TL;DR BoostSecurity.io is thrilled to announce ‘poutine’ – an Open Source security scanner CLI you can use to detect misconfigurations and vulnerabilities in Build Pipelines. Additionally, it can create an inventory of build-time dependencies so you can track known vulnerabilities (CVEs) as well. Today, the tool has about a dozen rules covering vulnerabilities found in GitHub Actions workflows and Gitlab pipelines. We have plans to add support for CircleCI, Azure Pipelines and more. The source code is published under the Apache 2.0 license and it is available on GitHub.

TL;DR: Granting repository "Write" access in an Open Source project is a high-stakes decision. We delve into the risks of insider threats, using a responsible disclosure for the AWS Karpenter project to demonstrate why strict safeguards are essential – branch and tag protection, code review, and especially controls around the publication of release artifacts. Also GitHub may be lacking in terms of auditing capabilities to help spot Indicators of Compromises (IoCs) in some scenarios.  

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.

Generative AI solutions and tools are being developed at a breakneck pace. Builders everywhere are doing whatever it takes to ship their products. Security left merely an afterthought. There are a myriad of concerns on the surface of these solutions including bias, privacy of information, and harmful output (i.e. hate speech). Looking deeper, issues can manifest within these solutions that are imperceptible. Imagine querying one of these solutions and receiving reasonable output in return. Unless you are a subject matter expert, the validity of the contents are likely to go over your head. You’re prone to instinctively trust the output. In some domains, this is harmless. Using code emitting from one of these solutions that is broken requires you to spend some time sharpening its rough edges. In biotechnology, a misdiagnosis from a generative AI solution might prescribe a medication or a certain procedure that could kill the patient. Generative AI is being built on a shaky foundation that could collapse at any moment. Is anyone paying attention?
