According to the GitHub Advisory (GHSA-hg4h-mv37-7x88), any computer with this package installed or running should be considered fully compromised.\n\nImmediate action is required: all secrets and keys stored on affected computers must be rotated immediately from a different, uncompromised system. While the package should be removed, there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the package installation, as the attacker may have gained full control of the system.\n\nThis is a critical supply chain incident affecting the npm ecosystem.
