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: 2.3.2; tarball SHA-256 0fe7b3d8ed7ec429ff5f53971bb933640ddb717f2dd39621a5d435b7664ac18a.
