US FTC Shutdown of 3FN Effect on Spam: None?

I’ve been monitoring spam using ATLAS for a while now, keeping track of spamming botnets etc using a spam trap. The shutdown of 3FN by the US FTC supposedly had an effect on spam levels. We saw this last fall with the 75% drop in spam after McColo was de-peered. Are we seeing it with 3FN?

I’m not so sure.

Below is a graphic showing you the top 50 countries sending our spam traps messages uniqued by sending IP and subject (which is designed to measure how big a spam botnet is, as opposed to mail message volumes). Note that the US FTC announcement was June 4, 2009.

On June 4 we see a big spike in spam activities (more bots sending more unique messages). This isn’t what we expected.

Still investigating but I don’t think we’ll see the kind of drops we saw last fall here.

Where are places like ComputerWorld getting their numbers then?

everyone has their own metrics and measurement areas. i trust the numbers that were posted in krebbs’ piece about cutwail2 specifically being kneecapped, but overall spam numbers just don’t seem down from here.

Seeing this is 6 months old, Russian criminals and their goverment never give up, Cutwail2 has been both Bulletproof, and getting support from 419 scam spammers, both in Russia, Ukriane, Nigeria, and Burkina Faso, and these 4 countries will do every bit to keep this going until World War 3.
