According to the GitHub Security Advisory, 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. The malicious package should be removed, though there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the initial compromise.\n\nGiven the severity of the threat and the potential for complete system compromise, users should treat any system that has run this package as potentially fully controlled by an external threat actor.
