I just got an email tonight from my "bank". Logos, official colors, all the fine print at the bottom, proud sponser of the Olympics, etc.
It was a long letter (to make it look offical no doubt) that said my account was not up-to-date and that I needed to update my password, etc. or I wouldn't be able to make any computer transactions and my account would be closed.
Putting the cursor on "clik here" came up with some weird url with .bankname_registration/update/blahblahblah.
Of course I didn't click it, and have warned my wife in the past about this stuff too. I just wonder about all the poor folks that DO get scammed by this stuff. (And no - most banks are not looking for an easy way to CLOSE your account!)
what you got is what they call "phissing". I got one from my credit union also, but i inquired with them in person without responding to the email.
