The npm package signup-embedder has been identified as containing malware. According to the GitHub advisory (GHSA-8j4q-hx83-pfq9), 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 package installation, as the outside entity may have gained full control of the system.\n\nThis is a critical supply chain incident affecting the npm ecosystem.
