SRI have a new (according to ISC, can't say either way personally) site detailing all manor of malware related activity. (http://mtc.sri.com/).

I haven't had a chance to search through the site in it's entirety (work, life etc.) but it looks like it is a good resource for those of us trying to protect against the latest threats.

It's definitely going in my bookmarks, if your interested in the area could be well worth a look.
