On `npm install`, npm fetches that URL and installs whatever bytes it returns, executing any lifecycle scripts contained in the fetched tarball — unpinned, integrity-unchecked, and outside the npm registry's publish controls. The shipped `index.js` is an empty stub, so the manifest-declared off-registry URL is effectively the entire install-time payload. The dependency source is a mutable third-party storage bucket; whoever controls that URL controls code running on the installer's machine at install time. The high version number (`99.9.1`) relative to a short, generic name is consistent with a dependency-confusion lure intended to win resolution against an internal `sc-wizard` package. ## Source: ossf-package-analysis (54691cc130e614ee031186f7e646c3e6076efad6105a6e9cad68f62aa736516b) The OpenSSF Package Analysis project identified 'sc-wizard' @ 99.9.1 (npm) as malicious.
