Background

rinto-poke31 is an npm package that has been identified as part of a malicious campaign targeting the npm ecosystem. This package is associated with the tea.xyz token reward initiative, which aims to inflate developer reputation scores by flooding the npm registry with derivative packages. The package is designed to automate the generation and publication of these derivative packages, potentially compromising the integrity of the npm ecosystem.

Vulnerability Detail

The vulnerability in rinto-poke31 stems from its malicious code that modifies the package.json file by removing private flags and altering version numbers. It generates random package names, often themed around Indonesian culture, and continuously republishes these variants to pollute the npm registry. This behavior not only compromises the affected package but also poses a risk to developers relying on the integrity of the npm ecosystem, leading to potential security breaches and reputational damage.

How To Fix

This package is malicious. Remove it and rotate any credentials it could have accessed.

npm uninstall rinto-poke31

If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
