    Summary: Malicious code in unfortunate_crawdad_emerald-79 (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 9b1c0d601c4b827fd86f48aff1ab51a397ef52f5ccd42b4b03947234dcc2f891.
