Subject: Phishing attack. Basic encoding

I was forwarded a very similiar message late last week.

When I loaded the page in IE it brought up the homepage of the domain
being phished and and a pop up window with a captcha image.  Some more
analysis of the page showed that the image was being pulled from a
Russian email site while the rest of the pop up from a host in
Germany.

I was unable to locate any exploit code and it never asked me for
actual credentials so it is my belief this is an attempt to get people
to decode captcha images so that some phishers/spammers can create
email accounts.
