Background

The eko-kolak88-ruro package is part of the npm ecosystem, which is widely used for JavaScript package management. This package is associated with the tea.xyz token reward campaign, which has been known to flood the npm registry with malicious packages. The primary function of this package is to facilitate the automatic generation and publication of derivative packages, which can inflate developer reputation scores for token rewards. However, its malicious nature poses significant risks to developers and users alike.

Vulnerability Detail

The vulnerability in the eko-kolak88-ruro package stems from its inclusion in a campaign that deploys malicious scripts designed to manipulate package metadata. These scripts, such as auto.js and autopublish.js, modify the package.json file to remove private flags, alter version numbers, and generate random package names. This behavior leads to the continuous republishing of variants, which pollutes the npm registry and can compromise the integrity of other packages. The origin of this vulnerability is linked to the exploitation of npm's publishing capabilities, allowing attackers to manipulate package data for malicious purposes.

How To Fix

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

npm uninstall eko-kolak88-ruro

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