Suspicious activity to my account

I've just opened the forum and I see this text in red:
"We have detected suspicious activity on your account.
We recommend changing your password here as soon as possible".
I have changed the password but are there more information to know who is the ip that tried to login to my account and I would like to know if someone succesfully logged to my account or only tried to do that.

Thanks

The email for resetting the password they sent had nothing but a TXT attachment. i DO NOT RECOMMEND opening it unless we have confirmation from PoE directly. This is too suspicious. Normal PoE emails have a certain distinct format and stuff. PoE might be hacked?

edit: i looked around in the forums and this is a thread worth having a look at.
