Is anyone else getting this problem ?
So far today we have received around 300 spams purporting
to be from various arms of MS and announcing a
new "Security Update".
Is MS looking into this ?
When will it be resolved ?

We are/were a registered MS developer - are other
developers getting the same problem ?
