The npm package express-ini has been identified as containing malware. According to the GitHub Advisory (GHSA-w3p6-c3cm-r253), 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.
