Malicious code in intimate_ostrich_amethyst-45 (npm)

Details

**Severity:** Critical

**Affected versions:** `= 3.1.4`

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: 3.1.4; tarball SHA-256 c2602bb843cad68aa7f593fca592887cf660bfcf72e918d1865320c0fed5ec38.
