120,000 out of 180,000 corporate customers of IT giant KPN failed to change their default password (welkom01), forcing them to shut down their portal due to the inherent security risks.

The first question that pops to mind is whose fault is it? Then you realize it was everyone’s: from system designers to customer relations to customers etc. Overall it was a complete communication failure. You can see how everyone assumed that the other realized the implications and would act to prevent such a ridiculous situation. Yet no one did.

This is really why I have my job. The things people assume… Sigh.
