Description

The npm package andi-jus57-ruro contains malicious code linked to the tea.xyz token reward campaign that flooded npm with over 15,000 spam packages in 2024. These packages include autopublish scripts that automatically generate and publish derivative packages with randomized names to inflate developer reputation scores for token rewards. The malicious payload modifies package.json files to remove private flags, alters version numbers, generates random Indonesian-themed package names, and continuously republishes variants to pollute the npm registry.

Impact

This malicious package pollutes the npm registry by flooding it with numerous derivative packages, potentially misleading developers and automated systems that rely on package metadata for trust and reputation. It manipulates developer reputation scores by artificially inflating package counts and versions, which could undermine the integrity of token reward systems tied to npm package publishing activity. There is no indication of direct exploitation or compromise of end-user systems beyond registry pollution and reputation manipulation.

Defensive guidance

The recommended mitigation is to avoid installing or using the andi-jus57-ruro package and other related packages from the tea.xyz token reward campaign. Registry maintainers and security teams should monitor and remove such spam packages to protect the ecosystem. Developers should verify package authenticity and provenance before use.

Summary

The andi-jus57-ruro npm package is part of a large-scale malicious campaign associated with tea.xyz tokens. It contains autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of derivative packages with randomized names. This behavior aims to manipulate developer reputation scores by inflating package counts and versions. The malicious code modifies package.json by removing private flags and changing version numbers, then repeatedly republishes variants with randomized Indonesian-themed names, contributing to registry pollution and potential ecosystem trust degradation.
