Before the Breach: Detecting npm Supply Chain Attacks Through Structural Signals

npm supply chain attacks aren't unpredictable—they exploit structural weaknesses like single maintainers, governance gaps, and abandoned high-impact packages that leave visible behavioral signals. Using proof-of-commitment scoring to analyze past attacks shows these vulnerabilities are detectable before exploitation, shifting from reactive incident response to proactive risk mitigation. For organizations relying on npm's ecosystem, recognizing these structural patterns becomes essential to protecting their entire software supply chain.
