A critical malware incident was identified in the npm package rsflows-pexml. According to the GitHub Advisory (GHSA-m2qp-j4c5-7m6m), any computer that has this package installed or running should be considered fully compromised.\n\nThe advisory warns that all secrets and keys stored on affected computers should 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 compromise, as the outside entity may have gained full control of the system.\n\nThis represents a supply chain attack through a compromised package in the npm ecosystem with critical severity due to the potential for complete system takeover.
