GMail and Last Account Actions

This happened

On Friday, 05/14/10, as usual, checking the GMail street saw an inscription above the message window, something like:
" YOUR ACCOUNT HACKED - more?"

(human memory is imperfect, I cannot vouch for authenticity)
under the link, which incidentally can be found at the bottom of the mailbox: " Additional Information "
Here is what was behind the link:

Total

Naturally, I came out of all sessions, changed the password and checked the password recovery system.
What do you think of such a convenient reminder of strange account events? Mine need to enter all e-mail services.

PS - the account was not opened on another machine, look carefully at the screen, it describes the sequence of actions aka, namely:
registration registered 3 days before this day from the USA in an unknown way.
