Background

The manda-32 package is part of the npm ecosystem and is associated with the tea.xyz token reward campaign. It is designed to facilitate the automatic generation and publication of derivative packages. This package has been identified as malicious due to its functionality that modifies package metadata and floods the npm registry with spammy packages, impacting the integrity of the ecosystem.

Vulnerability Detail

The vulnerability in the manda-32 package originates from its malicious intent to manipulate package.json files by removing private flags and altering version numbers. It generates random package names, primarily themed around Indonesian culture, and continuously republishes these variants. This behavior not only inflates developer reputation scores for token rewards but also pollutes the npm registry, making it difficult for developers to find legitimate packages. The malicious code can lead to security risks, including the potential for further exploitation of affected systems.

How To Fix

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

npm uninstall manda-32

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