Hey everyone, Mike Reavey here again.  We’re headed into the weekend and I wanted to check in and provide you with some more information about the Excel issue we are investigating.  As of right now it’s still just a single customer impacted.  But I want to reiterate that all of our various protection tools detect this malware and remove it.

The MSRC, together with the SWI team, have identified some workarounds that help stop the attack.  However we’re concerned that they might have an impact to the usability of Excel.  Based on some of the customer feedback regarding the recent Word workarounds, we want to take the extra time to fully vet our guidance. 

Of course, the Excel team is hard at work putting together the plan for an update as well. We’re working on an advisory through the weekend and will post it as soon as we are confident in the protection steps. 

- Mike
