Description

The npm package 'siska-brengkes9-ruro' 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, alters version numbers, and continuously republishes variants to pollute the npm registry.

Impact

The malicious package pollutes the npm registry with numerous derivative packages, potentially misleading developers and automated systems relying on package metadata. It manipulates package.json files to bypass privacy flags and artificially inflates reputation scores within the tea.xyz token reward system. While no direct exploitation or code execution impact is described, the registry pollution can degrade trust and integrity of the npm ecosystem.

Defensive guidance

Users and maintainers should avoid installing or depending on packages related to this campaign. Registry maintainers should consider removing these malicious packages and monitoring for similar autopublish scripts. Since this is a registry pollution issue, standard npm security practices such as verifying package provenance and using trusted sources are recommended.

Summary

This threat involves a malicious npm package that participates in an automated campaign to inflate developer reputation scores for tea protocol token rewards. The package includes scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) that modify package metadata by removing private flags and changing version numbers. It generates numerous derivative packages with randomized Indonesian-themed names and repeatedly republishes them, resulting in registry pollution and potential ecosystem disruption.
