The npm package pm-claude-skills-mcp has been identified as containing malware. According to the GitHub Advisory (GHSA-87v2-285p-xhrr), any computer that has 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 initial compromise, given that the attacker may have gained full control of the system.\n\nThis is a critical supply chain incident affecting the npm ecosystem.
