I first stumbled across this report while I was at SecureWorld in Boston this spring. One of the Keynote speakers, Bret Arsenault, General Manager of Microsoft's National Security Team, went over the 1H07 report and provided some spiffy bound hard copies for the attendees. It is really well done and a nice view of the current threats against the Windows Environment.

Now, Microsoft has released 2H07 for download. Sadly, no hard copies for me, but it's still a very good read. Available are the complete report and a "Key Findings" section suitable for 50000ft views.
