Spammer strategies

Posted by Michael Bloch in online world (Sunday March 4, 2007 )

Ever wondered about some of the weird and wonderful ways that spammers get their messages through to you and avoid detection?

Rick Conner of Rick’s Spam Digest has authored a very interesting and detailed article on spammer tricks and strategies. It includes information on:

– Transfer via open relay
– Use of offshore ISPs
– Pink contracts
– Insecure mailback scripts
– Open proxies / zombies
– Direct-to-MX software
– Forged headers
– Bogus addresses
– Obfuscated URLs
– Encoded message bodies
– Encrypted message bodies
– Disabled right-click
– Hashbusters
– Web bugs and beacons
– “Personalized” messages
– “Creative” misspelling
– Bogus text
– Obfuscated HTML
– DNS tampering
– Affiliates and portals
– Dictionary attacks

The article also contains links to further reading, detection methods and tools sprinkled throughout. In fact, Rick’s site contains just about everything an anti-spam vigilante would want to know.

As for how spammers get hold of your email address in the first place; see my article on the subject. If you’re looking for an anti-spam service; try my review on email filtering services – it contains a free trial offer.

  1. It’s funny. You can see this as a “How-to avoid” and a “How to” do something. If I was interested in Spamming, this would be a great starting point.

  2. Hi Chris, I guess you’re right – luckily all readers of this blog have the highest level of integrity and wouldn’t even think of engaging in such nefarious activity. I like to think that anyway :)
