The dependency is unpinned, carries no integrity hash, and is not resolved through the npm registry. On , npm fetches whatever bytes that host returns and installs them as a package, executing any lifecycle scripts ( / / ) contained in that artifact; the shipped index.js then re-exports the fetched module so also loads its code. The manifest further exhibits dependency-confusion shape: the scope with placeholder metadata (author , generic description, example.com repository) suggests a package intended to shadow an internal name during resolution. Control of install-time and import-time code execution on the installer's host rests entirely with the operator of . ## Source: ossf-package-analysis (fc751fb286e3a288e498adfc3b9b936c1ff40270a1c342047a7d778ce24936f4) The OpenSSF Package Analysis project identified '@flexmr/utils' @ 3.0.12 (npm) as malicious.
