Subject: AOL Spam down 27%
Date: Wed, 24 Mar 2004 16:44:50 +0200
Hi There,
Just saw this news article on a SANS NewsBites email...
http://www.forbes.com/technology/newswire/2004/03/19/rtr1305508.html
They saying they are seeing a 27% decline in spam entering there network
since the 20th of February.
They attributing it to the spam law that came into effect on the 1st of
January and that over time there tweaking of spam filters has improved
somewhat.
Now what I want to know is are those just numbers? And are the spammers
just sending less now and could send more in April and then less again
in
June, just some sort of up and downcycle like the stock market?
Or is it possible that the fact that the takeup of spf has something to
do with it?
Especially since AOL posted there records in early Jan?
Or maybe even a portion of it?
Cant check when the uptake really took off...
http://spftools.infinitepenguins.net/earlyadopters.php appears to be
broken :-(
Anyone got similar stats?
Wishful thinking?
Comments?
Cheers
Bradley

My own stats don't support that. Our dynamic Black List server keeps track
of the IP addresses used for Spam in the last 18 hours. Since I started it
at the beginning of the year, it has averaged about 1200 active records at
any one time. What I have noticed recently is very large swings with
periods of less than 800 active records and periods of over 1800 active
records.
These are basically Spam engines that don't play by the rules, and include
hijacked IP addresses. It probably doesn't include those Spammers that host
a number of servers on legitimately obtained address space, but without
digging deeply into the individual addresses, I have no way of knowing that.
