Supply Chain Zero Days: Closing the Gap Between Publication and Detection

Modern software development depends on open source packages. Developers and AI coding agents can pull new dependencies and versions into projects at speed, helping teams build and ship faster. But that speed creates a challenge for security teams. When a trusted package is compromised, malicious code can enter development environments and build pipelines before traditional vulnerability databases flag the threat. Organizations cannot manually review or block every update to foundational packages without slowing development. Therefore, most organizations scan newly downloaded packages against known vulnerabilities and block if needed. But, zero-day supply chain compromises won’t show up in vulnerability databases right away; and, because popular packages are already trusted, developer workflows and build pipelines are often configured to automatically pull their latest versions. If…
