Description

The npm package eko-jamblang57-breki contains malicious code linked to the tea.xyz token reward campaign. This campaign flooded 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. The intent is to inflate developer reputation scores to gain tea protocol token rewards and pollute the npm ecosystem.

Impact

This malicious package pollutes the npm registry with numerous spam packages, potentially degrading the quality and trustworthiness of the npm ecosystem. It manipulates package metadata to bypass publishing restrictions and continuously republish variants, which can mislead users and automated systems relying on package reputation. While no direct exploitation or code execution impact is described, the campaign undermines the integrity of the npm package repository and developer reputation systems.

Defensive guidance

Users and maintainers should avoid installing or depending on the eko-jamblang57-breki package and other related spam packages from the tea.xyz campaign. Registry maintainers should consider removing these malicious packages and enhancing detection to prevent autopublish spam. Developers should verify package provenance and metadata before use.

Summary

The eko-jamblang57-breki npm package is part of a large-scale malicious campaign associated with tea.xyz token rewards. It contains autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of derivative packages with randomized names. These scripts manipulate package.json by removing private flags and changing version numbers to bypass restrictions and enable repeated publication. This behavior results in a flood of spam packages in the npm registry, aiming to artificially boost developer reputation scores and disrupt the package ecosystem.
