Background
The test1df23 package is an npm module that is intended for use in JavaScript applications. It is designed to facilitate certain functionalities within the npm ecosystem. However, this package has been identified as containing malicious code that executes upon installation, posing significant security risks to users and their systems.
Vulnerability Detail
The vulnerability stems from the presence of preinstall and postinstall hooks in the package.json file of test1df23. These hooks trigger the execution of index.js during the npm install process. The index.js file contains code that sends an HTTP GET request to a hardcoded IP address (128.199.122.145) over plain HTTP, embedding the package name in the query string. This action leaks the installer's outbound IP address and confirms the successful execution of the code to the operator of that IP. This behavior is indicative of a dependency-confusion or typosquatting attack, which can lead to unauthorized access and data leakage.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall test1df23If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
