What this malware does

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: 2.4.2; tarball SHA-256 ffebf73f874c957dd668301a366650064b7e52d0b33aca0943fdd0e1f7d58807.
