Number 1, I highly doubt than a spam message would be very effective
using the FD list of address only. Number 2, this list is full of
security professional (white, black and grey) and I would guess that
most of the core users you see on here would not just run a attachment
or be fooled by the double extensions trick. Given there most likely are
"normal internet users" on this list but I would guess that number is
pretty low.

Every mailing list is targeted by spammers and phishing. There are
program that are designed to spider google and collect e-mail addresses.
Since this list is mirrored several times in several sites in different
countries, this shouldn't be a surprise.

This is true, GuidoZ could expand on this fact I know. If he is
around..lol Then again most corporate e-mails systems (and some people
at their house) have very in-depth spam filters and programs to weed out
spam and junk mail. The number would look different and should be
different.

I would guess that most spammers don't mail thru mailing list. Most
would use the thousands and thousands of relay bots all over the
internet to hide their e-mail in bulk. When I say in bulk, I mean in
bulk. To target a single list with a crafted message would be anymore
wasteful. Now that doesn't mean it wouldn't work, it would most likely.
But just like in stealing cars or wireless internet. Why take the time
to create the special message (or break the WEP) if you can send out a
general "New Microsoft patch" or "We need your banking info" and get a
10% return. There 10% return will be normal internet users that most
likely don't know about about computers, don't have AV and don't know
about the spam underworld. Spammers don't want to get caught, they want
to use the computers that are still infected with the CodeRed worm.
Unmanged computer heaven. ;)
