Background

The madan-poke9 package is part of a series of npm packages that have been associated with the tea.xyz token reward campaign. These packages are designed to inflate developer reputation scores by automatically generating and publishing derivative packages with randomized names. The functionality of madan-poke9 is compromised due to its malicious payload, which modifies critical files and repurposes the package for nefarious activities.

Vulnerability Detail

The vulnerability in madan-poke9 stems from its malicious code that alters the package.json file by removing private flags and changing version numbers. It generates random Indonesian-themed package names and continuously republishes variants to pollute the npm registry. This behavior not only compromises the integrity of the npm ecosystem but also poses risks to developers who may unknowingly use these tainted packages, leading to potential security breaches in their applications.

How To Fix

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

npm uninstall madan-poke9

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