For those not familiar with Shodan, this is one of the easiest ways to find vulnerable internet-connected hardware. This could be anything from personal webcams to gas pipeline control systems.
Also, this article should be a major heads up to everyone: DO NOT EVER use the factory default logins for your devices! Make unique logins and strong passwords for everything, and use MFA whenever possible.
@voltronic The threat research team at work has gotten more than one DEFCON/Black Hat presentation out of Shodan results. :-D

Yeah, I have a Samsung network printer that has the same functionality. Changing the login isn't enough; it's still constantly trying to connect to the cloud print server. I have its external connection denied through the router, but looking at my pi-hole logs shows it thrashing away.
