Mac Attack Signatures list? + I got linked to a blank page

I was just chatting with a Norton tech support person, and he mentioned there was a list for Attack Signatures for Macs that was separate from the page at

symantec.com/security_response/attacksignatures/

I have been unable to find the list via a search though.  Does anyone know where it is or how to find it?

 

The specific Attack Signature I'm trying to find more information on at the moment takes me to:

http://www.symantec.com/security_response/attacksignatures/detail.jsp?asid=27270

But that is a blank page.  I got to there from the Learn More button on my Firewall (Norton Internet Security for Comcast version) Does anyone have info on this?
