Description

The npm package agus-gembus4-riris was identified as containing malicious code as part of a large-scale spam campaign linked to tea.xyz token rewards. This campaign involved flooding the npm registry with over 15,000 spam packages in 2024. The malicious code includes autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. These scripts modify package.json files to remove private flags and alter version numbers, enabling continuous republishing of variants to inflate developer reputation scores and pollute the npm registry.

Impact

The malicious package enables continuous automated publishing of derivative packages, which pollutes the npm registry and can undermine trust in the ecosystem. It artificially inflates developer reputation scores within the tea.xyz token reward campaign, potentially misleading users and developers relying on reputation metrics. There is no indication of direct exploitation or compromise of user systems beyond registry pollution and reputation manipulation.

Defensive guidance

Users and developers should avoid installing or using the agus-gembus4-riris package and other packages linked to the tea.xyz spam campaign. Registry maintainers and security teams should monitor and remove such spam packages to preserve ecosystem integrity.

Summary

The malicious npm package agus-gembus4-riris is part of a widespread spam campaign associated with the tea.xyz token reward system. It contains autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of derivative packages with randomized names. The payload modifies package.json by removing private flags and changing version numbers to facilitate repeated republishing. This behavior aims to artificially inflate developer reputation scores and flood the npm registry with spam packages, degrading the ecosystem's integrity.
