This would be very interesting to see how message labs verified this. How do
they know if a given ip is hijacked?

Subject: [Asrg] 2. Spam Measurements - Analysis - Spam Delivery
According to Message Labs, Inc. in this recent MSNBC article
(http://www.msnbc.com/news/940853.asp) over 70% of all spam
is sent via
hijacked computers. This supports what Barry Shein has been
saying for some
time and we need to take this factor into account.

"Researchers say hundreds of thousands of vulnerable
computers are being
used to launch spam campaigns now. In fact, 70 percent of all
spam is now
sent this way, according to anti-spam firm Message Labs Inc.
ù and perhaps
6 to 7 billion spam messages are routed through hacked home
computers."
