I received the same and the invoice came from an individual named “Shin Deryl”
They couldn’t have chosen a worse scam. The email included Paypal’s anti-phishing footer (including a warning that official emails from PayPal include the customer’s full name) and the invoice was for Bitcoin.
The email was addressed “Dear Customer” and I’d rather douse myself in napalm and run into a bonfire than buy cryptocoins.
