ultrasurf false detection

We are seeing traffic listed as ultrasurf simply by visiting https://s3.amazonaws.com. This seems to have just started in the last few days. Anybody else seeing this on Firesight?

Bryan,

We had a new ASA and Firesight installed a couple weeks ago and we see the exact same thing. Its reporting https://s3-us-west-1.amazonaws.com as web application Ultrasurf. 

I have an open case on this issue but have not heard back from the TAC since submitting logs and pcaps. I'll update if I get a solution but it's obviously something in the software.
