I concur on the increase. We saw a 50% falloff after 11 August, but the last
two weeks has seen our spam hits rising to +30% what they were before 11
August. Based on the patterns we've seen, I expect our spam count in
December to be six times what it was in December of last year, and three
times what it was this past August.

For over 4 years, we have been building and maintaining a database of known
spam sources. The growth of spam this past month has been just incredible,
and our database size statistics give a good indication of how much spam has
Comparing the size of the database today (2003/09/14) to the same hour one
month ago (2003/08/14), we have seen the database grow by 48%. The volume of
spam email traffic has not grown quite as fast (thank goodness for small
favors!), but is dramatically up. A couple of days last week, we reached the
point where over 99% of all externally originated mail server connections
were spam related -- either proxy server port scans or attempts to deliver
The other disturbing trend: The mind-boggling insecurity of Academic
computing networks. Its not just Universities either. We are seeing an ever
expanding number of K-12 systems compromised -- especially in the U.S.,
Japan, and Korea. The most insecure Universities appear to be in the U.S.,
France, and Germany.
A final trend that I find disturbing: The number insecure Government
computer networks. Especially troubling is that Egypt and Turkey appear to
have MAJOR problems keeping their Government computer networks secure. If
spammers can hijack these systems, what are terrorists capable of doing with
Just a few thoughts for this Sunday.
