Malicious code in low_hummingbird_replicate_automation (npm)

Details

**Severity:** Critical

**Affected versions:** `= 2.2.1`

Part of a self-republishing campaign: the package ships autopublish3.js, which in a loop gives the package a new random name, bumps its version, rewrites package.json and runs `npm publish` to publish the package again under the new name. Self-replicating publication is the propagation step of a registry worm and fills the registry with copies. Version examined: 2.2.1; tarball SHA-256 27350f7324f64a2c30cb92c938c4e5133d65e27b6efba13d97b15986732027e7.
