Open Source Sustainability Is an Attack Surface Problem
Unmaintained, underfunded open source is not just a reliability risk — it is how attackers get in. The xz Utils backdoor proved that maintainer burnout is a security vulnerability with a CVE number.
Event-Stream npm 2018: Package Trust Lessons That Still Apply
The event-stream npm incident remains the cleanest case study in maintainer-handoff risk. What it taught the ecosystem, and what we still ignore in 2026.
Immature Open Source Projects as a Supply Chain Risk
xz-utils, event-stream, node-ipc: a decade of supply chain incidents traces back to one root cause — thinly maintained, single-person open source projects.
Corporate Dependence on Volunteer-Maintained Projects: A ...
Corporations run on code that volunteers maintain for free. Here's a data-backed risk map—from left-pad to the xz-utils backdoor—and how to manage it.
Succession Planning for Open Source Projects: Why It Rare...
Most open source maintainers have no succession plan. That gap has already caused real incidents, from event-stream to XZ Utils, and it explains why.
Measuring Project Health: Bus Factor, Commit Velocity, an...
Bus factor, commit velocity, and maintainer concentration predicted the xz-utils and event-stream incidents before any CVE did. Here's how to read these proxies — and where they mislead.
Monitoring Package Maintainer Changes as a Threat Signal
Most package hijacks start with a maintainer change nobody was watching. Registry metadata makes these events observable — if you bother to look.
Safeguard Open Source Manager: Understanding the Health of Your Dependencies
Vulnerability counts do not tell the full story. Open Source Manager evaluates the health, maintainability, and trustworthiness of the open-source projects your software depends on.
Single-Maintainer Bus Factor Risk in OSS
A single person maintaining critical infrastructure is one medical emergency, burnout, or coercion event away from a supply chain crisis. The bus factor is not a theoretical metric.
npm colors and faker Sabotage: When Maintainers Revolt
The maintainer of colors and faker deliberately corrupted his own packages, affecting thousands of projects. It raised uncomfortable questions about open source sustainability and trust.
