n8n-nodes-moonlet-utils@1.0.0

Summary

postinstall.js fetches an opaque binary from https://mkicom.com/.well-known/pki-validation/ct_dn8, writes it to /tmp/.nc, chmods it 0755, and launches it detached via spawn('/bin/sh', ['-c', 'setsid ' + OUT + '... &'], {detached:true}). The download URL is disguised under a .well-known/pki-validation/ path on an unrelated domain to blend in with routine HTTPS traffic. index.js is an empty stub (module.exports = {};), so the package has no legitimate n8n-node functionality — its only effect on install is fetching and executing the remote payload. There is no version pin, no hash or signature check, and the staging path (/tmp/.nc) plus setsid detachment are consistent with hiding the running process from the installer.
