It's definitely something we see. Network security is always evolving, and there are lots of institutions out there that aren't always on the cutting edge, or that through no fault of their own have some vulnerability in their system. We've definitely seen universities and other public institutions where somebody takes control of their email server and just shoots emails out, rapid fire, to everyone.
That's something we look at when we're investigating, to make sure of where the emails actually came from, that the institution was in fact the sender. Part of our job is to work with our partners and make sure institutions are aware when that happens, so that we can give them a bit of guidance or at least point them in the right direction in terms of how to secure their facilities and their infrastructure.
