According to the GitHub Advisory (GHSA-829c-v26f-5g9m), any computer that has this package installed or running should be considered fully compromised.\n\nAffected systems require immediate remediation. All secrets and cryptographic keys stored on compromised computers should be rotated immediately from a different, unaffected computer. 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 is a critical supply chain incident affecting the npm ecosystem.
