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

Typosquat

  1. Find it

    Search your lockfiles and build artifacts for baryon-ini-biomimicry-entanglement (all published versions).

  2. If you installed it — respond

    baryon-ini-biomimicry-entanglement is a typosquat — you almost certainly intended a legitimately-named package. Remove baryon-ini-biomimicry-entanglement, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

  3. Did it already run?

    If baryon-ini-biomimicry-entanglement 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.
