Background
The nasrul-poke89 package is part of the npm ecosystem, which is widely used for JavaScript package management. This package, like many others, is intended to facilitate the development and distribution of JavaScript applications. However, it has been identified as part of a malicious campaign that exploits npm's publishing capabilities to generate and distribute harmful code. The package is associated with the tea.xyz token reward scheme, which has led to the proliferation of numerous derivative packages that can compromise the integrity of the npm registry.
Vulnerability Detail
The vulnerability in nasrul-poke89 stems from its association with a malicious campaign that modifies the package.json file to remove private flags and change version numbers. It generates random package names, often themed around Indonesian culture, and continuously republishes these variants to clutter the npm registry. This behavior not only inflates developer reputation scores for token rewards but also poses significant risks by potentially introducing harmful code into 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 nasrul-poke89If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
