My father applied for a new credit card the other day. MumbleBank sent him an email notifying him about some security arrangements for the new account — the details aren’t important. This mail contained HTML content, and a link to MumbleBank’s website where he had to configure something. This is where the fun begins.
The link’s text said mumblebank.com/creditcard. The link target was http://mumblebankcreditcard/foo/. Obviously these aren’t the same. He knows enough to hover the mouse over the link and to get nervous when the link text doesn’t match the target URI.
