A critical malware incident was identified in the npm package @mastra/mcp-registry-registry. According to the GitHub Security Advisory (GHSA-5w62-p653-57mf), any system that has installed or executed this package should be treated as fully compromised.\n\nThe advisory recommends immediate action: all secrets and cryptographic keys stored on affected computers must be rotated from a different, uncompromised system. While the malicious 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, as the attacker may have gained full control of the system.\n\nAffected users should assume complete system compromise and take appropriate incident response measures.
