Malicious code in hollow_wildebeest_silver-94 (npm)

Details

**Severity:** Critical

**Affected versions:** `= 1.1.2`

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: 1.1.2; tarball SHA-256 01f53d63acbd1e1c1275a099ac442ab52446e4fa180395088fd49c7a168f193c.
