This is a list of default credentials for various infrastructure devices. There are lots of lists like this out there. Now ask yourself, why is this useful to anyone? It's useful because people don't change the default credentials. A more interesting question is, perhaps, why are there default credentials at all? Why is it possible for me to set up a functioning system with credentials that are not specified by me. This is changing...yet it's still a problem, and perhaps a bigger one when you intersect it with virtualization. Go check out the VMTN appliances. Here's a whole new breed of ready-built systems with default credentials.
