Description

The npm package 'iwan-brengkes8-sumpek' is part of a malicious campaign linked to the tea.xyz token reward scheme. It contains 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 to inflate developer reputation scores and pollute the npm registry.

Impact

The malicious package undermines the integrity of the npm registry by flooding it with numerous derivative packages, potentially misleading users and automated systems relying on package metadata. It manipulates developer reputation scores, which could affect trust and reward mechanisms within the tea.xyz token ecosystem. There is no indication of direct exploitation or compromise of user systems beyond registry pollution and reputation manipulation.

Defensive guidance

No specific patch or fix is indicated for this malicious package. Mitigation involves avoiding use or installation of packages associated with the tea.xyz token reward campaign and monitoring for suspicious autopublish scripts in npm packages. Registry maintainers and security teams should consider removing or blocking these packages to prevent further pollution. Users should verify package authenticity and provenance before installation.

Summary

This threat involves a malicious npm package that is part of the tea.xyz token reward campaign flooding the npm ecosystem. 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 payload modifies package.json by removing private flags and changing version numbers, facilitating repeated republishing of variants. This behavior aims to manipulate developer reputation scores for token rewards and results in registry pollution.
