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.

ok mr. moderator... i think the real problem to phishing exists is the weak process of login systems today... anyone just needs a login and password, to be authenticated, i think web aplications needs to change login systems... to be more tight... and the phishers maybe loose there hope to grep information very easy with just a username and password... my idea and solution to a new login system is this... creating a 3rd field, this 3rd field the user will choose... it will work like saying yes this is the real bank system welcome back mr. user insert your password... the process... 1rst page user -> puts the username... second page.. 3rd field -> what is your cat name? now the user knows that this was the question that he have put int the 3rdfield from the real bank site (he can put what he want)... password ?? -> user puts the password.. he is athenticated. now the phishers they have more work, needs two process to gain access to the bank user account... first they need to colect the username to get the 3rd field... and they need to put the 3rdfield in the false website... to get the password... but this is the deal... when a user or anyone, puts the username in this login system needs to proceed with a password, if not, if the user close the browser, if he tries 3times and can't login, the system will block the username and send a email to the real user, a code to unblock the username and force the user to change the username and 3rd field... and now the phishers don't know again what will be the new username and 3rdfield... this system, is nothing from other planet and i think that help a lot the users, and will stop a litle or a big % this phisher mans... regards Nuno Costa -----Original Message----- From: Krul Thomas [mailto:Thomas.Krul () psepc-sppcc gc ca] Sent: April 27, 2005 10:31 AM To: 'Alex'; incidents () securityfocus com Subject: RE: Discovering and Stopping Phishing/Scam Attacks I received a phishing scam email for RBC Bank literally moments ago. The Web site is based in the Czech Republic with very little in the way to disguise the address of the site. (At last check, the site was still up at: http://updatestatus.webz.cz/rbc/cgi-bin/rbaccess/login.html) Odd, either there are some newbie phishers out there, or they are starting to realise that no matter how much they disguise their sites someone will be having them shut down soon enough so catching the uninformed in the few moments they have is paramount. Will we be seeing an increase in the diversity of referring addresses in a flooding attempt to catch the last remaining moms and pops who don't know better versus well-crafted addresses that don't arouse suspicions? -----Original Message----- From: Alex [mailto:incidents () alex gotdns org] Sent: Tuesday, April 26, 2005 7:51 PM To: incidents () securityfocus com Subject: Re: Discovering and Stopping Phishing/Scam Attacks I agree that checking by referer addresses is a powerful way to detect phishing sites, but such logs can easily be adverted? Doesn't some anti-popup software remove referer fields? Simple use of javascript can allow a page to fetch anything without showing up in referer logs. While we are on the subject, has anyone come across commercial and/or government websites being (illegally?) mirrored? For example, I recently came a website located on a (Asian?) hosting provider where the content of the website was EXACTLY that of a well-known US govt website. (It appeared that they ran the equivalent of a recursive "wget" on the real site and hosted the files). It appeared to be several layers deep. Why would anyone want to do that? -Alex ------------------------------------------------------------------------ -- Test Your IDS Is your IDS deployed correctly?
