This looks like just Messenger spam. It is designed to pop up a message on
the target's Windows desktop. The messages commonly promote malware
disguised as legitimate utilities. They send commonly these to any or all of
1025 through 1029, since Windows creates a listener on one of the low
dynamic ports. Usually I see an accompanying attempt against UDP 137 with
the same content.
