Description

The npm package 'putri-klanting49-breki' is part of a malicious campaign linked to tea.xyz token rewards. It contains autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The payload modifies package.json files to remove private flags and changes version numbers, enabling continuous republishing of variants. This activity pollutes the npm registry and inflates developer reputation scores fraudulently.

Impact

The malicious package undermines the integrity of the npm registry by flooding it with numerous derivative packages, which can mislead users and automated systems relying on package metadata. It artificially inflates developer reputation scores within the tea protocol token reward system, potentially enabling fraudulent gains. 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 trusting packages related to this campaign. Registry maintainers should consider removing these packages and monitoring for similar autopublish scripts. Developers should verify package authenticity and metadata before use.

Summary

This threat involves a malicious npm package associated with the tea.xyz token reward campaign. The package includes autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of derivative packages with randomized names. The malicious code alters package.json by removing private flags and modifying version numbers, facilitating repeated republishing of variants. This behavior aims to manipulate developer reputation metrics and flood the npm registry with numerous variants, degrading the ecosystem's integrity.
