Background
The nasrul-poke38 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 aims to inflate developer reputation scores through the automatic generation and publication of derivative packages. This behavior not only compromises the integrity of the npm registry but also poses a significant risk to developers who may unknowingly use these tainted packages.
Vulnerability Detail
The vulnerability in nasrul-poke38 originates from its involvement in a malicious campaign linked to the tea.xyz token reward system. The package contains scripts designed to automatically modify its own package.json file by removing private flags, altering version numbers, and generating random package names. This results in the continuous republishing of these variants, which pollutes the npm registry and can lead to security risks for developers who may inadvertently install these compromised packages. The malicious payload can also lead to unauthorized access or manipulation of projects 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-poke38If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
