The npm package winston-prism has been identified as containing malware. According to the GitHub Advisory (GHSA-3xpg-2wmm-jjj2), 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 compromise.\n\nThis represents a critical supply chain attack through a compromised package in the npm ecosystem, with potential for complete system compromise on any machine where it was installed.
