I got this email from service@intl.paypal.com, with the title: 

Your account has been limited until we hear from you.

I think this is a scam / spoof email because I don't see any notification in my Paypal account and this is Hotmail account is not used as my Paypal login. (It used to be not any more for more than a year.)

But the troubling thing is, the TO: field has my old password as my name, then my email in brackets. A screenshot below should clarify what I'm saying. I've blurred my email and the two red arrows are pointing to what was my old password in plain text.

Is there anything I could do to protect myself? Does that mean the sender has me under their "contact book" with my name as my password? I have already forwarded the email to spoof@paypal.com.



It seems like the spammer got your personal information including your password through a security breach somewhere. Why did they use your password instead of your name? I would say it was an honest mistake on their side. They just mixed up the fields when designing the spam mail.

When you are still using the password somewhere, you should change it ASAP. In the future you should avoid using the same password for different services. Data breaches become more and more frequent, and they even hit larger companies which really should know how to secure their systems. Using a password manager like KeePass can help you to manage all the different passwords.
