Description

The npm package eslint-angular-react contains malicious code that executes a preinstall script during npm install. This script sends system information such as OS, username, working directory, and hostname to a hardcoded IP address, acting as a reconnaissance beacon. The package does not provide any legitimate ESLint functionality and appears to be a typosquatting or dependency confusion attempt targeting developers. Installing this package may lead to full system compromise, requiring immediate secret and key rotation.

Impact

The package's preinstall script leaks sensitive environment information to an attacker-controlled server. The presence of this package on a system indicates a high likelihood of full compromise, potentially allowing attackers to access secrets and keys stored on the machine. Removal of the package alone may not eliminate all malicious artifacts or backdoors introduced by the attacker.

Defensive guidance

Remove the eslint-angular-react package immediately if installed. Rotate all secrets and keys stored on the affected system from a separate, trusted machine. Conduct a thorough security assessment of the compromised system to identify and remediate any additional malicious software or backdoors.

Summary

The eslint-angular-react npm package declares a preinstall lifecycle script that automatically runs on npm install without user interaction. This script performs a curl request to a hardcoded IP address (http://109.71.252.153:8080/) sending the installer's OS, username, working directory, and hostname as query parameters. The package contains only a README and package.json, with no actual ESLint plugin code, indicating it is a malicious typosquatting package designed to collect reconnaissance data from developers' environments. According to the ghsa-malware source, any system with this package installed should be considered fully compromised, necessitating secret and key rotation and removal of the package.
