What this malware does

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: 2.3.4; tarball SHA-256 ce54dc3b5212e9e3c4ea35938e592aeba77d0683479bb3b4d9cb0d254ae97fb5.

Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for itchy_gecko_magenta-98 (version 2.3.4).

  2. If you installed it — respond

    Remove itchy_gecko_magenta-98 from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If itchy_gecko_magenta-98 was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
