This has been the preferred method of hijacking e-bay accounts too. You get a message, seemingly from e-bay. that tells you your account is in trouble (usually for some reason that will outrage you so you click through ASAP). Then they tell you to follow the enclosed link, log in and verify some detail or other.

By the time you realize something is up, you've already sent your usrname and password to some leech who will then use your account to list one of those "I'm currently traveling in another country and the product itself is in Spain / Greece/ Turkey / Uzbekistan" ads that are the #1 hallmark of e-bay fraud.
