Description

The amateur_chimpanzee_z3n npm package is part of a malicious campaign linked to tea.xyz token rewards. It contains autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The payload modifies package.json files to remove private flags and alters version numbers to repeatedly republish variants. This activity pollutes the npm registry and inflates developer reputation scores fraudulently.

Impact

The malicious package pollutes the npm registry with numerous derivative packages, which can degrade the quality and trustworthiness of the ecosystem. It enables fraudulent inflation of developer reputation scores tied to the tea.xyz token reward campaign. There is no indication of direct exploitation or compromise of user systems from this package alone.

Defensive guidance

Mitigation involves avoiding use or installation of this package and its derivatives. Registry maintainers and security teams should monitor and remove such autopublished malicious packages to preserve ecosystem integrity.

Summary

This threat involves the amateur_chimpanzee_z3n npm package, which is associated with the tea.xyz token reward campaign. The package includes autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of derivative npm packages with randomized names. These scripts modify package.json by removing private flags and changing version numbers to enable continuous republishing. The goal is to flood the npm registry with numerous variants, artificially inflating developer reputation scores for the tea protocol token rewards system.
