Citibank identity theft scam

I get these kinds of things all the time, but this one is especially sneaky and legitimate looking. Here’s an email I received this afternoon — allegedly from the address admin@citi.com — threatening the potential loss of my CitiBank debit card unless I changed the password immediately.

The email sounds serious:

Recently there have been a large number of identity theft attempts targeting CitiBank customers. In order to safeguard your account, we require that you update your Citibank ATM/Debit card PIN.
This is, of course, a scam to get CitiBank debit card numbers and PIN numbers. What follows will seem elementary to most who read this blog, but I’m doing this for the sake of those who aren’t familiar with this stuff.

One way to check the validity of any of these scam emails is to open the email and click “View” and “Options”. This reveals a pull-down screen:

This gives you a look at the message “Headers,” the language that the Internet uses to deliver the message. Unfortunately, these can be manipulated, but there’s always a giveaway. Here are the headers from the scam email:

At the very bottom of the headers above, notice two lines that begin with an X. These “X parameters” will not look this way on a valid email. Here’s an example of how they look on an email just I sent myself.

If you’re ever concerned about the validity of an email, always begin your investigation here.

There’s another sneaky giveaway on this one. The scam email contains a link that looks like it goes to the Citibank Website. Take a look:

https://www.citibank.com/signin/citifi/scripts/login2/update_pin.jsp

Here’s the html code for that link:

This is the actual URL that the link is going to:

Once you get there, a nice, official looking Citibank page with a pop-up appears, where the unknowing are supposed to fill in their account and PIN numbers:

The only way to really protect yourself against Internet crime is to be knowledgeable about it. Consider yourself informed.
