Is it just me, or should this title be "Zero-Day Attack"? What's the "Under" all about?

Phrasing is a little weird, but I read it as that this is a zero-day that is actively being exploited, but a patch is not coming for a while.

Supporting evidence for this interpretation: http://blogs.technet.com/b/msrc/archive/2013/11/05/microsoft... which includes "We are aware of targeted attacks, largely in the Middle East and South Asia."

They mean that it is being exploited in the wild, not just theoretically.
