If i get hacked, do i have a port with unknown label/service when running nmap command?

  • If i get hacked, do i have a port with unknown label/service when running nmap command?

  • Or is more common that you get a malware/virus that make mess in the operating system without
    network involvement?

  • Is there a program/script that could run nmap commands a few times a day and i get notified if
    some port maybe has service “unknown”?
