This is some interesting research. I am wondering though: Does anyone know whether there are any potential legal issues with scanning devices / networks that do

  As someone who has scanned e.g. all of 24.0/8 from a work machine, you do get angry emails to abuse@<your-reverse-dns-name>. I don't think there are legal issues here -- these are all public services on the internet. But installing software like the author did is legally problematic.

  It's legal to port scan networks you don't own (from a US perspective), though logging in and/ or performing changes to the device are definitely not. As another person has mentioned, you will get a lot of abuse emails but there's nothing illegal about port scanning by itself. Source: I run Shodan (http://www.shodanhq.com http://www.shodanhq.com)

  It's almost always against the terms of your provider's AUP.

    That's why you do the scanning from someone else's router. :-)

      Replacing possible AUP-violation with definite felony.

        Isn't some AUP violation a felony, because you're using a computer without authorisation?
