I received an email from Ebay.com (vs. ebay.com) telling me that my account has a problem. It included a link to what appeared to be the ebay login page, but upon further looking it was a "look alike" site. I viewed the source and found that the page owner was using get another 3rd party service to collect the data (user name and password), so I notificed the 3rd party service, and they have subsequently shut down their service to this scammer. (I also notified ebay ;-)
Please be on the look out for these scams, and always use the "secure" feature when logging in.
Additionally, here's an article on MSNBC (sorry for the pop-up):
http://www.msnbc.com/news/957191.asp titled "EBay thief reveals tricks of the trade - ‘Kenneth’ and friends claim $2 million stolen from Net users" It's well worth reading.
