RE: Discovering and Stopping Phishing/Scam Attacks

I think that the system you're proposing will stop *current* phishing 
schemes but it wouldnt take a lot for the phishers to come up with a way 
to retrieve that third piece of information from the user.

A lot of places verify information with the "third question" you're 
referring to (pet's name, childhood superhero, mother's maiden name, etc) 
and identity theft is still a problem for us.

If a user is willing to give their username and password to an unverified 
source, it only takes a little more work to get that third piece of 
information from them.
