Details

Part of a self-republishing campaign: generated names of the form <adjective>_<animal>_<colour>-<number>, each package shipping the same autopublish.js, which runs `npm publish --access public` to publish the package again. Self-replicating publication is the propagation step of a registry worm and fills the registry with copies. Version examined: 2.4.3; tarball SHA-256 a3154921b8a06cfa66c41cf8d689a9e16610ddda9e78c8db51e986bcf1e056d9.
