Description

The npm package fajar-rangi51-riris contains malicious code linked to a large-scale spam campaign involving over 15,000 packages in 2024. This malware uses autopublish scripts to automatically generate and publish derivative packages with randomized Indonesian-themed names. The payload modifies package.json files to remove private flags and alter version numbers, enabling continuous republishing of variants. The campaign aims to inflate developer reputation scores for the tea.xyz token reward system and pollutes the npm registry with spam packages.

Impact

This malicious package pollutes the npm registry with spam packages, potentially degrading the quality and trustworthiness of the ecosystem. It manipulates package metadata to bypass privacy settings and repeatedly publishes variants, which can mislead users and automated systems relying on package reputation. While no direct exploitation or active attacks are reported, the campaign undermines the integrity of the npm package ecosystem and token reward mechanisms.

Defensive guidance

Users and maintainers should avoid using the fajar-rangi51-riris package and related variants. Registry maintainers and security teams should monitor for and remove such spam packages to preserve ecosystem integrity. Since this is a malware campaign rather than a software vulnerability, remediation focuses on detection and removal rather than patching.

Summary

The fajar-rangi51-riris npm package is part of a widespread malicious campaign associated with tea.xyz token rewards. It contains autopublish scripts (such as auto.js and autopublish3.js) that automate the creation and publication of numerous derivative packages with randomized names. The malicious code modifies package.json by removing private flags and changing version numbers to facilitate repeated republishing. This behavior results in registry pollution and artificially inflates developer reputation scores within the tea protocol ecosystem.
