Background

The tehah-nutafday-kob package is part of the npm ecosystem and is associated with the tea.xyz token reward campaign. This package is designed to facilitate the automatic generation and publishing of derivative packages, which can inflate developer reputation scores for token rewards. However, it has been identified as containing malicious code that compromises the integrity of the npm registry.

Vulnerability Detail

The vulnerability originates from the malicious payload embedded within the tehah-nutafday-kob package. This payload modifies the package.json file by removing private flags, altering version numbers, and generating random package names, which can lead to the pollution of the npm registry. The malicious scripts (auto.js, autopublish.js, etc.) continuously republish these variants, potentially harming developers and users relying on the integrity of the npm ecosystem.

How To Fix

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

npm uninstall tehah-nutafday-kob

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