Am no expert in this area, yet your question certainly deserves some response asap.

You may want to change your Apple ID password right away:
What to do: If you think your Apple ID has been compromised - Apple Support
Eg: Above article says:
"Gain control of your Apple ID (NB: There is much more info. in the above article as well)
- Change your Apple ID password
- If your Apple ID password has been changed by someone else, reset your password.
- Go to appleid.apple.com to update any of personal or security information that isn't correct or that you don't recognize.
- Check with your email address* provider to make sure that you control every email address associated with your Apple ID. If you don't control an email address, work with your email provider to regain control or use a different email address.
* In China mainland and India, you can use your phone number as your Apple ID"
