I was once investigating an uptick of telnet traffic, when I came across something that looked like a pppoe router web interface.

For shits and giggles, I decided to try admin/admin, and to my surprise, I was logged into this device with full control.

I immediately logged out, but I could have easily changed the password or changed their configuration, knocking them offline...

I'm sure there are legal issues surrounding that, and I have no idea what kind of devices connected to the thing, but you'd be surprised how many random internet junk is out there with default credentials.
