Description

The npm package cindy-rangi16-riris was identified as containing malicious code linked to a large-scale spam campaign involving over 15,000 packages. This campaign, associated with the tea.xyz token reward system, uses autopublish scripts to generate and publish numerous derivative packages with randomized Indonesian-themed names. The malicious payload manipulates package metadata to remove privacy flags, alter version numbers, and continuously republish variants, thereby polluting the npm registry and inflating developer reputation scores illegitimately.

Impact

This malicious package campaign pollutes the npm registry with numerous spam packages, potentially misleading developers and automated systems that rely on package metadata and reputation scores. It artificially inflates developer reputation metrics within the tea.xyz token reward system, which could distort trust and reward mechanisms. There is no indication of direct exploitation or compromise of user systems beyond registry pollution and reputation manipulation.

Defensive guidance

Users and maintainers should avoid installing or depending on the cindy-rangi16-riris package and related variants. Registry maintainers and automated systems should implement detection and removal mechanisms for these spam packages to preserve ecosystem integrity.

Summary

The cindy-rangi16-riris npm package is part of a widespread malicious campaign flooding the npm registry with spam packages related to the tea.xyz token reward system. It contains autopublish scripts that automatically generate derivative packages with randomized names to artificially boost developer reputation scores. The malicious code modifies package.json files by removing private flags and changing version numbers, enabling continuous republishing of variants. This activity results in registry pollution and undermines the integrity of the npm ecosystem.
