## AI overview

This article examines the mini Shai-Hulud supply chain worm, which affected more than 400 packages. It argues that malicious code can enter during package build and distribution without a CVE, and that teams should strengthen preventive security across registries, GitHub Actions, CI/CD pipelines, dependencies, AI coding agents, and configuration files.
