That there is the hallmark of your system being hacked!

  • Take it offline
  • Close any open ports on your router (also check it for infected Firmware)
  • Wipe it (the Pi4)
  • Check all network connected equipment (better to be safe)
  • Start over
  • Never open up ports to Node RED, without knowing how to correctly secure it.
