The Search Engine More Dangerous Than Google

It's stunning what can be found with a simple search on Shodan. Countless traffic lights, security cameras, home automation devices and heating systems are connected to the Internet and easy to spot. Shodan searchers have found control systems for a water park, a gas station, a hotel wine cooler and a crematorium. Cybersecurity researchers have even located command and control systems for nuclear power plants and a particle-accelerating cyclotron by using Shodan. ... A quick search for "default password" reveals countless printers, servers and system control devices that use "admin" as their user name and "1234" as their password. Many more connected systems require no credentials at all — all you need is a Web browser to connect to them.'"

Re:astounding that defaults are not tougher

Using a complex default will fool people into thinking the default is secure, and more people will fail to change it. If you're using the same default for every device, it doesn't matter what you use, it's not secure and needs to be changed.

Now they could issue a different default for every device, but that would require printing a unique card for each device, which is significantly more effort than just telling users to change the default login.

You hit a good point. There is a corollary to it, most devices have a method of resetting the login to the default (usually something that requires physical access to the device) because there are a significant number of times when for one reason or another the correct login credentials have been lost. If the manufacturer does not use the same default login credentials for every one of a particular device and the end user has lost the card they sent with it that has the default credentials (an eventuality that is likely in those cases where the changed credentials have been lost) the company will either have to have maintained a database of the default credentials for every one of their devices they have shipped, or the end user will be SOL (which will probably result in them being very unhappy with the manufacturer).
The fact of the matter is that a lot of these devices are going to be things which are infrequently accessed, so even if you file the credentials away in a "safe, secure" location by the time you need them again you may have forgotten where that was.
