As the holiday season gets closer, expect the number of phishing emails to go up. Recently, for the first time in my experience, I got one that used a secure socket layer server (SSL) (see email below). You know, the kind of website that starts with https://.
The intent of SSL is to create an encrypted tunnel between your PC and the web server. In addition, and here is the important part, it includes a digital certificate. The certificate is supposed to be examined by you to determine whether the server name in the certificate matches the URL you just typed in. If there is a difference, there is a probability that someone is trying to masquerade as someone else.
So, in theory, if you see a secure server address, you are supposed to feel safe. But. The theory doesn’t always hold true. In practice, if the URL doesn’t match the certificate, your browser should warn you of a discrepancy. The problem is, most people ignore the warnings because so many webmasters forget to renew their certificates so it is common to get warnings.
What’s even worse, cross-site scripting, frame-injection attacks, and browser bugs can allow phishers to run their own code as if it were from your own bank’s website (thus using their SSL connection and certificate). In addition, they could have a domain that sounds like your bank’s when it isn’t. According to the article, in 2005 over 450 SSL attacks were documented. I have no idea what it is in 2007 or what it will be in 2008 but I would guess it is/will be higher.
With these types of attacks, it really comes down to remembering that banks/credit card companies don’t send security emails to customers telling them to log in to a site and give them personal financial information/logins/passwords that they already have.
As they used to say on TV, “Let’s be careful out there.”
