Description

The npm package joko-kupat41-sukiwir 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 inflate developer reputation scores and pollute the npm registry.

Impact

The malicious package can degrade 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 package metadata to bypass privacy settings and inflate reputation scores, which could undermine trust in npm packages and disrupt legitimate package discovery and usage.

Defensive guidance

Users and maintainers should avoid installing packages associated with the tea.xyz token reward campaign and monitor for suspicious autopublish scripts in npm packages. Registry maintainers should consider removing or blocking such malicious packages to protect the ecosystem.

Summary

This threat involves a malicious npm package used in a token reward campaign flooding the npm registry. The package includes scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) that automate the creation and publication of derivative packages with randomized names. These scripts modify package metadata to remove privacy flags and increment version numbers, enabling continuous republishing of variants. The goal is to manipulate developer reputation scores for the tea protocol token rewards and to pollute the npm ecosystem with numerous malicious or spam packages.
