Hey Groovemeister53,

Thanks for the question. Please report any suspected phishing emails to us, if still available:

What to do with suspicious iCloud emails

If you receive a suspicious email, select the message text so that it is highlighted. Choose Forward as Attachment from the Message menu (OS X Mail) or the Actionsmenu (Outlook). Send the email to abuse@icloud.com. This provides Apple's legal department and law enforcement with useful information to help prevent future phishing emails.
