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: 3.4.3; tarball SHA-256 cdf7bcc56962d977f34fdb72789ce2b6aaac0020f0debb9ce4d55de8257ac352.
