Unusual pattern of compromised accounts

["Pollock, Joseph" <PollockJ () EVERGREEN EDU>]

Has anyone observed the following:


1.        A cluster of compromised accounts with no indication of a common factor such as clicking on a phishing link. 
Users have no idea how the compromise occurred.

2.       The culprits change the user's direct deposit authorization

3.       They may have been familiar with the Banner system.

4.       No other activity was observed.

We are looking for other indications,  such as compromised desktops,  but have found nothing as yet.

Please reply outside the list if you wish.
