Background

The manud-nofty-muatu package is part of the npm ecosystem, which is widely used for managing JavaScript packages. This package is associated with the tea.xyz token reward campaign, which has been linked to a series of malicious activities aimed at inflating developer reputation scores. The package's functionality is compromised by the inclusion of scripts that automatically generate and publish derivative packages, leading to pollution of the npm registry.

Vulnerability Detail

The vulnerability in the manud-nofty-muatu package stems from its malicious payload that modifies the package.json file. It removes private flags, alters version numbers, and generates random package names, primarily themed around Indonesian culture. This behavior not only compromises the integrity of the npm registry but also poses a risk to developers who may unknowingly use these tainted packages. The origin of this vulnerability is traced back to the tea.xyz token reward campaign, which exploits the npm ecosystem for malicious purposes.

How To Fix

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

npm uninstall manud-nofty-muatu

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