What this malware does

This package appears to be part of the tea.xyz token reward campaign that flooded npm. These packages typically contain autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) designed to automatically generate and publish derivative packages with randomized names to inflate developer reputation scores for tea protocol token rewards. The malicious payload modifies package.json to remove private flags, changes version numbers, generates random Indonesian-themed package names (some variants are also in English), and continuously republishes variants to pollute the npm registry.

Detection & response playbook

Malicious package

  1. Find it

    Search your lockfiles and build artifacts for nconf-cryptography-paleoanthropology-janus (all published versions).

  2. If you installed it — respond

    Remove nconf-cryptography-paleoanthropology-janus 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 nconf-cryptography-paleoanthropology-janus 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.
