You're essentially appropriating other people's computing resources for your own agenda, even if it's a good one, without the owner's permission. That's a crime

You're essentially appropriating other people's computing resources for your own agenda, even if it's a good one, without the owner's permission. That's a crime. I'd just suggest using the scanning portion to identify unsecured connections that should be added to a firewall's blacklist. Maybe that could be a good SAAS service that would provide a blacklist of all unsecured IOT devices and printers to everyone interested for blacklisting purposes.
