Notification said I was hacked
So about an hour ago I got a notification (similar to imessage or text) by something along the lines of “apple safety” or “apple security” that say I was hacked. I clicked on it and it had said I was hacked by a calendar subscription. I unsubscribed but I am concerned as to whether or not they still have my stuff. I went through a ton of discussions and found almost the same story. I’m freaking out and any help would be highly appreciated.
