Description

The npm package erick-bakwan27-ruro contains malicious code linked to the tea.xyz token reward campaign, which flooded npm with over 15,000 spam packages in 2024. This malware uses autopublish scripts to automatically generate and publish derivative packages with randomized names. The payload modifies package.json files to remove private flags, alters version numbers, and generates random Indonesian-themed package names. It continuously republishes variants to pollute the npm registry and inflate developer reputation scores for token rewards.

Impact

This malicious package pollutes the npm registry with spam packages, which can degrade the quality and trustworthiness of the npm ecosystem. It manipulates package metadata to bypass privacy settings and continuously republishes variants, potentially misleading users and automated systems that rely on package reputation. While no direct exploitation or code execution impact is described, the campaign undermines the integrity of the npm package ecosystem and developer reputation systems.

Defensive guidance

Users and maintainers should avoid using the erick-bakwan27-ruro package and related packages from the tea.xyz token reward campaign. Registry maintainers should consider removing these spam packages and enhancing detection mechanisms to prevent autopublishing spam packages. Monitoring for packages with similar autopublish scripts and randomized Indonesian-themed names can help identify and block this campaign.

Summary

The erick-bakwan27-ruro npm package is part of a large-scale malicious campaign associated with tea.xyz token rewards. It contains autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) that automate the creation and publication of derivative packages with randomized names. These scripts modify package.json by removing private flags and changing version numbers, enabling continuous republishing of variants. The campaign's goal is to flood the npm registry with spam packages, artificially inflating developer reputation scores to gain token rewards within the tea protocol ecosystem.
