The npm package @gleamkit/socket.io was found to contain malware. According to the GitHub Advisory (GHSA-666h-5h3g-crf4), 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 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, given the potential for full system control by an outside entity.\n\nUsers should treat any system that has run this package as potentially fully compromised and take appropriate incident response measures.
