I didn't say I was "guessing", I said it wouldn't surprise me.
And I've been running Linux since I got on the Internet, so the hack
didn't occur on my end.....

Okay folks, look around you at the history of things. For more than 2 decades now,
Microsoft's software products have been at the top of the list of software having
security problems in CERT ( goto http://en.wikipedia.org/wiki/CERT_Coordination_Center
and search for Microsoft) alerts. Viruses have, for the past two decades, routinely
infected peoples computers, obtained complete lists of people email "friends",
visited web sites, contents of files on your disk, trashed your disks, and otherwise
wrecked havoc repeatedly.
Anyone on this list, who has participated in mail to and from this list, would provide such viruses
access to email addresses which are supposed to be "restricted" to this list's members.
There is no such thing as "security" when Microsoft's software is involved, and as soon
as you are on a network, security becomes even more difficult to achieve.
"Guessing" that it might be an inside job is a little bit silly when there are
countless ways that people on this list have exposed the list members by their use of
insecure software systems and the downloading of virus laden content from the internet.
Accounts are being hacked, but as Phil notes, the "From:" headers of an email message tell you all you need
to know to understand where it "did not" originate from. The last secure SMTP sever will have recorded in a
"From:" header, the location the "last" insecure server to have been involved in transmitting an
email message.
Look over how the SMTP protocol works. Authentication of "sending" email was not happening in the original design, and only
recently, has that been "used" by ISPs and hosting companies interested in "not" supporting spam and other abuses of
the email systems. This means that certain "open" systems or "insecure" systems, can provide a link from the world of
"spam" if they can be accessed.
That's what you need to focus on to understand whether your account was
compromised.
SMTP allows email to be from anyone, and to anyone, if the servers don't
authenticate the origination and secure the transmission of the content. Until
that happens, we will always have this kind of stuff going on…

IIRC, Yahoo! took over for most of the Bells. My Pacbell.net account is now
managed by Yahoo!, and I had a similar event happen last year, as well as a
friend of mine who had her account with another Baby Bell compromised.
Considering how much support is off-shored these days, it wouldn't surprise me if it was
an "inside job".

Thanks Phil. Yes, I'm not sure how it was done but the settings are
correct in my PC. AT&T has helped me to assign a new password to my
account to shut this down. They say it appears to have been hacked on
the AT&T web mail site.
Interesting. I saw no actual evidence in the scam mail itself that your account
had been hacked.
This particular message was sent through Yahoo's webmail service. Anyone could
subscribe to the amsat-bb list and see who its contributors are, so they would
know who to send the scam spam to.
(Wait -- does Yahoo provide service for swbell.net?)
Without cryptographic authentication it's easy to forge email from anyone; SPF
helps somewhat but it's often not implemented and is frequently ignored even
when it is. In this case I perused the headers myself and saw the IP address
41.71.175.195, which happens to be in Nigeria (look it up!)
It's somewhat trickier to intercept the replies. In this case they did it with
a Reply-To: header to a fraudulent account (rdwel...@yahoo.com) that'd be easy
to miss if you weren't looking for it.
I had theorized that they did this because they hadn't actually gotten into
your swbell.net account, but it's possible they did it anyway so that they'd
still get any replies from victims after your account had been secured or shut
down. It would take a little longer to get rdwel...@yahoo.com shut down since
it's at a different service provider.
