Description

The npm package dian-mendut69-breki contains malicious code linked to a large-scale token reward campaign that flooded npm with over 15,000 spam packages in 2024. The malicious payload 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 change version numbers, enabling continuous republishing of variants. The campaign aims to inflate developer reputation scores to earn tea protocol token rewards and pollutes the npm registry with spam packages.

Impact

The malicious package enables automated generation and publication of numerous derivative packages, polluting the npm registry and potentially misleading users and automated systems relying on package metadata. It manipulates package.json files to bypass privacy settings and artificially inflates developer reputation scores tied to the tea protocol token rewards. While no direct exploitation or system compromise is described, the campaign degrades the integrity of the npm ecosystem and may affect trust in package authenticity and reputation metrics.

Defensive guidance

Users and organizations should avoid installing the dian-mendut69-breki package and other related spam packages from the tea.xyz campaign. Registry maintainers and security teams should monitor and remove such spam packages to preserve the integrity of the npm ecosystem. Since this is a malware campaign rather than a software vulnerability, remediation involves blocking and removing malicious packages rather than patching software.

Summary

The dian-mendut69-breki npm package is part of the tea.xyz token reward campaign that introduced over 15,000 spam packages into the npm ecosystem in 2024. It contains autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) that automate the creation and publication of derivative packages with randomized names. The malicious code modifies package.json files by removing private flags and altering version numbers to facilitate repeated republishing. This activity inflates developer reputation scores to gain token rewards and results in significant pollution of the npm registry.
