npm Supply Chain Audit: The Checklist Most Teams Stop Too Early
The article discusses the importance of comprehensive npm supply chain audits. It highlights a significant security breach involving the ua-parser-js package, which had no known vulnerabilities before a malicious release occurred. The piece emphasizes that most teams only conduct partial audits, missing critical layers of risk assessment.
- ▪In October 2021, the ua-parser-js package was widely used and had no reported vulnerabilities.
- ▪A compromised npm token led to a malicious release that affected millions of installs within hours.
- ▪A complete npm supply chain audit should cover three layers, but most teams only perform one or two.
