ISP phishing

[Gadi Evron <gadi () tehila gov il>]

Hi guys. I notice a large increase in recent weeks of ISP directed
phishing - largely because of worms moving backward to using the user's
own domain for the spam, but not just in the from: address.

I believe this started out as a "let's feel this out" or "wow, that
worked, let's phish ISP's directly too". I now have several reports that 
point to this becoming a serious problem.

Old with a spark of new, but definitely a problem.

Anyone else dealing with this?
