A critical malware incident was identified in the npm package @mplay-core-lib/utilities. According to the GitHub Advisory (GHSA-w8v3-x4pv-78rp), 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, given that the outside entity may have gained full control of the system.\n\nAffected users should treat this as a critical security incident requiring comprehensive system remediation beyond simple package removal.
