A critical malware incident has been identified in the npm package equiviewer. According to the GitHub Advisory (GHSA-98hr-v28p-r787), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers 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 represents a critical supply chain compromise affecting the npm ecosystem.
