Thanks Amazon and Google!

If you're a phisher your basic strategy is to convince the victim that he's talking to some site he regularly does business with. Now, you can't control the user's experience when he's talking to the legit site so what you do instead is make the experience you provide as much like the legit site as possible, hence tools for mirroring the site you're impersonating. If you're a potential victim of impersonation, you want to get the user into the habit of not trusting indicia that the phishers can easily indicate. To that end, you might want to tell your users not to click on URLs they receive in e-mail claiming to be from you. Unless, that is, you're Amazon:

Greetings from Amazon.com.

We're writing to let you know that we are having difficulty processing your

top right menu.

2. Choose the option "Change payment method" (found under "View by Order"
in the "Where's My Stuff" box).

3. After you sign in, you will see all your current open orders. You can
click the "View or change order" button beside any order and make changes.

4. Click "Change" button in the "Payment Information" box beside "Payment
Method." At this point, you may review your current payment method, choose

Please note: This e-mail was sent from a notification-only address that
cannot accept incoming e-mail. Please do not reply to this message.

Now, this mail has been sent in plaintext (i.e., text/plain) so there aren't any links. (Though you could of course get caught by cutting and pasting out of the message.) Unfortunately, Gmail decided to help me out and turned everything that looks like a domain name or URL into a link. Now, as it happens I had screwed up something with my credit card and this isn't a phishing message and, but it just as easily could have been. For extra credit, if you put a link to a different location in your message, Gmail will display it exactly like the links it auto-formats. Outstanding!
