Background

The kentung-17 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 publication of derivative packages, which can inflate developer reputation scores for token rewards. However, it has been identified as containing malicious scripts that compromise the integrity of the npm registry.

Vulnerability Detail

The vulnerability in the kentung-17 package arises from its inclusion of autopublish scripts that modify the package.json file to remove private flags and alter version numbers. It generates random package names, often themed around Indonesian culture, and continuously republishes these variants to pollute the npm registry. This behavior can lead to a significant increase in spam packages, affecting the overall health of the npm ecosystem and potentially compromising the security of applications that depend on these packages.

How To Fix

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

npm uninstall kentung-17

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