Why enforce supply chain security at the artifact registry

Software supply chain attacks increasingly exploit open-source dependencies and install-time scripts, allowing malicious code to run on developer machines or CI systems before traditional downstream scanners can detect it. The passage argues that artifact registries should serve as a centralized security control point, vetting packages at ingestion so policies apply consistently across developer workstations, builds, and production environments. This approach is presented as especially important for self-propagating malware such as Shai-Hulud and its successors, which can steal credentials, exfiltrate data, or consume resources while avoiding detection. Registry-level dependency firewalls can automatically block known malware, delay newly published packages through cooldown periods, enforce vulnerability thresholds based on CVSS, EPSS, and CISA KEV data, and restrict problematic software licenses. The growing use of AI coding agents further increases dependency volume and reduces human review capacity, making automated package trust controls more important across the software development lifecycle.
