## 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: 2.1.1; tarball SHA-256 d889bb1a1d8f63c6103dc3a023c76def899e0c3e0d888409a086dc995b12762c.
