    Summary: Malicious code in temporary_smelt_lavender-81 (npm)

    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: 3.3.1; tarball SHA-256 3d62a6900cb2eec57c55e599f930c466dcd4ca3539ad7b2ca55779b0fbccba6a.
