## From the sources

Part of a self-republishing campaign: the package ships auto.js, which in a loop gives the package a new random name, rewrites package.json and runs `npm publish` to publish the package again under the new name. Self-replicating publication is the propagation step of a registry worm and fills the registry with copies. Version examined: 1.4.4; tarball SHA-256 d7a004f21796f6884acc016de74cb95c0db3e7e8b5220b38b15cf40befdadaa0.
