The npm package depcruise-wrap-stream-in-html version 99.9.1 is a hollow package designed to mimic an internal helper of dependency-cruiser. It installs a runtime dependency from an arbitrary HTTPS tarball hosted on an unrelated Google Cloud Storage bucket. This allows the bucket owner to change the tarball contents at any time without republishing to npm, bypassing registry scanning and version pinning. The package appears to be a dependency-confusion or smuggling lure.
