Background

The utomo-tahu70-riris package is part of the npm ecosystem and is associated with the tea.xyz token reward campaign. This package is designed to facilitate the generation and publication of derivative packages, which can inflate developer reputation scores for token rewards. However, it has been identified as containing malicious code that compromises its integrity and the security of the npm registry.

Vulnerability Detail

This vulnerability originates from the package's design to include autopublish scripts that modify the package.json file. The malicious payload removes private flags, alters version numbers, and generates random package names, leading to the continuous republishing of variants that pollute the npm registry. This not only affects the integrity of the affected package but also poses a risk to developers relying on npm for secure package management.

How To Fix

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

npm uninstall utomo-tahu70-riris

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