The npm package monitoring-service-util was found to contain malware. According to the GitHub Security Advisory (GHSA-mc6r-4967-53wm), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate action: all secrets and keys stored on affected computers should be rotated from a different, uncompromised system. While the package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning removal of the package alone may not eliminate all malicious software that resulted from the installation.\n\nThis represents a critical supply chain attack through a compromised npm package with potential for complete system compromise.
Indicators of compromise
- Packages

Remediation
- Immediately isolate any system that has monitoring-service-util installed or running from the network
- Rotate all secrets, API keys, credentials, and cryptographic keys from a different, uncompromised computer
- Remove the monitoring-service-util package from all affected systems
- Conduct a full forensic analysis of affected systems to identify any additional malicious software or persistence mechanisms
- Review system logs and network traffic for signs of unauthorized access or data exfiltration
- Consider rebuilding affected systems from clean media if full compromise is suspected
