Analysis of a Mail Scam

September 16, 2007

It is actually surprising that that actually a spam/scam phishing mail actually made it past Gmail’s filter, given that I have only had a handful of spam mails making through out of the years I’ve had the account.

If that made through, I’m sure other people would have received the same thing as well, so it might be a good idea to share with others this information, lest someone gets their bank account broken into.

Besides marking out my email addresses with XXXXX, the entire body of the message remains the same:

Received-SPF: neutral (google.com: 76.224.245.158 is neither permitted nor denied by domain of update@yahoo.com) client-ip=76.224.245.158;
smtp.mail=update@yahoo.com

The parts highlighted in red is the ones that people should look out for. Firstly, Bank of America decided to send me a mail via Yahoo, how interesting. The second part, being that instead of linking to Bank of America’s website, an IP address is used for this purpose. That’s a giveaway that the server isn’t legitimate.

Doing a reverse DNS lookup via 'host' yields the following information:

adsl-76-225-156-194.dsl.pltn13.sbcglobal.net

Isn’t that interesting to find out that Bank of America has to rely on someone’s home ADSL connection. sbcglobal.net is one of the America’s Internet providers, so I assume this has originated from somewhere in the US.

Doing a 'traceroute' seems to confirm that it came from somewhere in the East Coast, possibly New York, and the machine is still up and running.

Well either the hacker is really dumb, or some poor guy’s machine has been compromised and became an unwitting accomplice in a phishing scam attempt. If you are one of the few who has received any warning email from Bank of America, take note, and don’t fall for it.
