package.json declares no-for-of-loops as its own dependency and devDependency, with the source pointed at http://pack.nppacks.com/npm/no-for-of-loops instead of the npm registry. On npm install, npm fetches a tarball from this host over unauthenticated plain HTTP with no integrity hash, and installs its contents into the consumer's node_modules. The domain operator can serve arbitrary, mutable bytes on each fetch, meaning any code shipped from that host runs inside the installer's dependency tree. The main module's header additionally self-identifies the package as a 'Security Research Testing Purpose' artifact, and the package description is a bare 'NPM', consistent with a hijack-vector proof-of-concept rather than a functional utility. The auto-execute condition is satisfied: any default npm install of this package resolves and installs the attacker-controlled tarball without user opt-in.
