SPAM: Ebay Fraud SPAM

I received some more fraud spam, the kind that is basically a web form in a mail message. This time, it attempted to deceive me into revealing my Ebay password. It's pretty cleverly done. Like the recent Paypal fraud SPAM, they author uses many images from Ebay, but when the form is submitted (from the email message), the data (Ebay password) goes to "/ailabouni.com". It's really the freakin' Wild West out there. Never, ever, ever, send passwords through email, or trust that a message you get is "real." For posterity, here's the fraudulent SPAM.

SPAM: Email address fishing.

I noticed a new form of SPAM today, which didn't even contain a URL, just an email address. So i guess they are just fishing for active email addresses. Here's the message:

***************************************************^
Hello,  I'm 22 years old female and my name is Anna.  I saw your profile
on the net and found to be interesting.. email me back at
 Megan_647_knoged@hotmail.com if you want to exchange pictures or whatever.. 

Hugs, later...

*****************************

Why do i think Anna is bogus? Two reasons, apparent from this line in the headers:

Received: from sender1590 (YahooBB219030032091.bbtec.net [219.30.32.91])
        by kurma.ewranglers.com (8.11.6p2/8.11.6) with ESMTP id
        h7CCGwu18838; Tue, 12 Aug 2003 07:16:58 -0500 (CDT)

My machine, kurma.ewranglers.com, that received the mail message is the lowest priority backup mail exchanger (MX) for ewranglers.com. It shouldn't be getting mail unless three other machines fail to accept mail. And since kurma delivered the message to lakshmi (the primary MX for ewranglers.com) 4 seconds after it received it, it seems very unlikely that lakshmi was inaccessible when the message was delivered to kurma. So it seems that the person deliberately picked a backup MX to dump the SPAM on. I've previously seen spammers do this. I suspect it's because they think that backup MXs will be "more accepting" than the primaries. (That isn't the case for my machines, though that's irrelevant for this piece of spam.)

The second clue is that the machine that dumped the SPAM on kurma identified itself as "sender1590," even though it's IN ADDR record in the DNS identifies itself as "YahooBB219030032091.bbtec.net".

SPAM chronicles, part 1.

I compiled some spam stats and stuck them in my "old" journal on my site. For some reason, i feel better about keeping my content on my machines, so don't be weirded out when the URL is something other than LJ. If you care, which you probably don't. But anyway, the SPAM thing is an becoming a more active crusade, and there will probably be more posts in this vein to ignore.
