The 'sixseven1' package in the npm ecosystem is identified as malicious software. Installing or running this package results in a full compromise of the affected system, potentially allowing an attacker complete control. Due to the nature of the compromise, simply uninstalling the package may not remove all malicious artifacts or backdoors introduced. The advisory recommends treating any affected system as fully compromised and rotating all credentials from a different, secure environment.

Full system compromise on any computer with the 'sixseven1' package installed or running. All secrets and keys stored on the compromised system are at risk and should be considered exposed. The malicious code may persist beyond removal of the package, indicating potential for ongoing unauthorized access or control.

Remove the 'sixseven1' package immediately. Rotate all secrets and keys from a separate, uncompromised machine. Because the system is considered fully compromised, further forensic analysis and remediation may be necessary to ensure complete removal of malicious software. No official patch or fix is available; remediation relies on removal and credential rotation.
