A critical malware incident was identified in the npm package mastraqqq. According to the GitHub Advisory (GHSA-7vj9-63m9-3x7f), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate removal of the package and rotation of all secrets and keys from a different, unaffected computer. However, due to the nature of the compromise, there is no guarantee that removing the package alone will eliminate all malicious software that may have been installed as a result of the initial infection.\n\nThis represents a critical supply chain attack through a malicious npm package with potential for complete system takeover.
