Description

The npm package react-router-dom.js version 1.0.0 is identified as a malicious multi-stage information stealer. Upon installation, it executes a payload that opens a new terminal and compromises the host system. Any computer with this package installed should be considered fully compromised, and all stored secrets and keys must be rotated from a secure machine. Removing the package alone may not eliminate all malicious software introduced.

Impact

Full system compromise on any computer with the package installed. All secrets and keys stored on the compromised machine are at risk and should be rotated immediately from a different, secure computer. Removal of the package does not guarantee removal of all malicious components, indicating persistence mechanisms or secondary payloads may be present.

Defensive guidance

Immediately remove the react-router-dom.js package version 1.0.0 from all affected systems. Rotate all secrets and keys stored on compromised machines from a secure environment. Conduct a thorough investigation and system cleanup, as removing the package alone may not fully eradicate the malware. Consider rebuilding affected systems to ensure complete remediation.

Summary

The react-router-dom.js package version 1.0.0 on npm contains malicious code that acts as a multi-stage information stealer. The malicious payload executes during installation, opening a new terminal and potentially granting full control of the compromised computer to an attacker. This threat can lead to complete system compromise and exfiltration of sensitive information such as secrets and keys.
