The ADP -- a payroll service -- passwords (which, interestingly, aren't in the headline), are probably the ones that, despite being smallest in number, offer the most opportunity for direct financial disruption.
The ADP employee site hasn't changed in the past ten years and still uses basic auth. It's horrible. And freaky. When you login to your new company account, it shows all paystubs from your past employers too. [With the implication of your current payroll department being able to see how much you were getting paid at all your previous jobs since it's the same account?]
The article here says that the account information that was compromised can. I'm not sure if that is a result of bad reporting on the same level as that related to FTP in the article, or the accounts that were compromised are different than the ones for the website you are talking about.
The more power you wield in an organization the less competent with technology you are.
