Description

The npm package budi-semur84-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 enables automated spamming and republishing of npm packages, which can degrade the quality and trustworthiness of the npm registry. It facilitates fraudulent inflation of developer reputation scores tied to the tea.xyz token reward system. While no direct exploitation or code execution impact on end users is described, the campaign pollutes the package ecosystem and may lead to indirect risks such as supply chain confusion or trust erosion.

Defensive guidance

The recommended mitigation is to avoid using or installing the budi-semur84-ruro package and other related spam packages from the tea.xyz campaign. Registry maintainers and users should monitor for and remove such spam packages to preserve ecosystem integrity.

Summary

The budi-semur84-ruro npm package is part of a large-scale malicious campaign associated with tea.xyz token rewards. It contains autopublish scripts (such as auto.js and autopublish.js) that automate the creation and publication of derivative packages with randomized names. The malicious code manipulates package.json by removing private flags and changing version numbers to enable repeated publication. This behavior aims to inflate developer reputation scores fraudulently and pollute the npm registry with spam packages, undermining the integrity of the ecosystem.
