Hi Steve -
A French security expert named David Bizeul wrote the best study I've ever read on the RBN. I covered it here, along with a link to the .pdf.
However, another important group to watch is Rock Phish.
And don't miss the CloudMark study on the Economics of Phishing by Chris Abad. A link to that study is in my Rock Phish post above.
Thanks for the hat tip, Stan. I added my two cents worth below.
