The Search Engine More Dangerous Than Google
mallyn writes "This is an article about a search engine that is designed to look for devices on the net that are not really intended to be viewed and used by the general public. Devices include pool filters, skating rink cooling system, and other goodies. 'Shodan runs 24/7 and collects information on about 500 million connected devices and services each month. 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.'"

I mean, how hard is it to ship new devices with something tougher than admin and 1234?
they should at least change the account name from "admin" to "luggage"....
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.

Dinitrous Monoxide however is quite a laughing matter.
So the person setting it up is lulled into thinking that the default "4nk^&nW3)(&" is secure and doesn't need to be reset (despite any attacker being just one web search away from learning the "better" default)? Using a default of '1234' is a great way of reminding even minimally competent people that the password needs to be changed from default *right now.* Unfortunately, there are enough people out there not even minimally competent about security that this continues to be a problem.
To that end, the best option (but scarcely used on hardware interfaces) is to force someone to login as the admin before the device is functional, and during that login to force them to set a new password (with certain password rules prohibiting foolishly simple passwords). Do this, and the problem almost goes away, but the new problem of constant password recovery questions flooding tech support will commence. Most companies, sadly, choose the less secure/less pesky route of just letting it run with the default perpetually.
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.

Which begs the question: Why are our prisons accessible from the internet in the first place?
