There is currently an EVE mail going around from someone claiming to be from EVE Online Customer Support saying that account security has been compromised and asking players to go to a certain link to log in and change password. This email is not from CCP, and several players have wound up victims of this scam unwittingly.

We urge you to be careful whenever you receive emails of this nature, and to always double-check links. It's much better to be safe than sorry.
