These have been around for awhile, I'm not on my home machine at the moment or
I'd post a link to a blog analysis of this sort of thing.  Although it's 
impossible to tell due to the lack of figures from either side (PKI phishing 
vs. client cert use) it may well be that there's more use of PKI to attack 
bank clients than to defend them.

Fascinating!

This may be the first phishing e-mail I've seen that uses
a message related to digital certificates for attacking the
client; I am not a customer of Comerica.

Has anyone else seen this before?

Had to remove the link so it would get past the spam-filters;
apologies if you see multiple postings.

I did notice this reference to certificates in the phishing blabla message.

I checked very quickly at comerica.com, they don't seem to use client PK 
pairs (nor certificates), merely the usual name/password authentication.


If the target financial institution was using client authentication, it 
would be interesting to see phishing scenario details, but that's not 
the case until shown otherwise.


I'm not impressed by the phisher blabla message.
